tft display vs super amoled display hindi for sale

Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.

TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.

OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.

आपके स्मार्टफोन की डिस्प्ले के बारे में आप कितना जानते हैं? डिस्प्ले के नाम जैसे कि AMOLED, OLED, LCD, TFT के बारे में आप कितना विस्तार से जानते हैं? इनके नाम बहुत छोटे हैं, लेकिन इनमें से कौन-सा बेहतर है, किस रिफ्रेश रेट के साथ आता है, रेज़ॉल्यूशन कितना है इन सब सवालों को जानकर यदि आप अपने लिए स्मार्टफोन चुनना चाहते हैं तो आपके इन सभी प्रश्नों के उत्तर मिलेंगे यहाँ।

पिछले कुछ सालों में स्मार्टफोन की डिस्प्ले काफी बेहतर हुई हैं। लेकिन प्रत्येक स्मार्टफोन डिस्प्ले के साथ जो शार्ट-फॉर्म एक संक्षिप्त नाम जुड़ता है, जैसे कि AMOLED, LCD, इत्यादि वो केवल नाम नहीं बल्कि अपने आप में एक तकनीक है। स्मार्टफोन पर लगे पैनल AMOLED, OLED, LED, LCD, IPS, TFT, LTPS, इत्यादि होते हैं। ये सभी पूर्णत: अलग होते हैं।

पहले ही इतने टाइप के पैनल मौजूद हैं, ऐसे में स्मार्टफोन निर्माता द्वारा फैंसी नामों का इस्तेमाल जैसे कि Apple द्वारा Super Retina XDR और Samsung द्वारा Dynamic AMOLED ग्राहकों के बीच भ्रम या असमंजस को और बढ़ा देता है।

डिस्प्ले के टाइप तो बहुत सारे हैं जैसे कि TFT, LTPS, AMOLED, OLED, IPS, LCD इत्यादि। लेकिन इन दिनों TFT, LTPS जैसी डिस्प्ले काफी कम हो गयीं हैं। किफ़ायती दामों पर और मिड-रेंज में आने वाले फोनों में आपको IPS LCD डिस्प्ले मिलेगी। लेकिन इन सबका विस्तार से समझें, तो मतलब क्या है ?

LCD का मतलब या फुल फॉर्म है लिक्विड क्रिस्टल डिस्प्ले (Liquid Crystal Display)। इसमें लिक्विड क्रिस्टल्स की एक श्रंखला दी जाती है जिसके पीछे एक बैकलाइट होती है। इस डिस्प्ले टाइप का हर जगह आसानी से उपलब्ध होना और कम दामों में इसका निर्माण इसे स्मार्टफोनों के लिए एक प्रचलित विकल्प या पसंद बनाता है।

स्मार्टफोनों में आपको दोनों डिस्प्ले TFT और IPS मिलती हैं। TFT का फुल फॉर्म है – Thin Film Transistor, जो LCD का ही एक बेहतर या एडवांस्ड वर्ज़न है, जो एक एक्टिव मैट्रिक्स (active matrix) का इस्तेमाल करता है। active matrix का अर्थ है कि प्रत्येक पिक्सेल एक अलग ट्रांजिस्टर और कपैसिटर से जुड़ा होता है।

TFT डिस्प्ले का सबसे बड़ा फायदा यही है कि इसके प्रोडक्शन में तुलनात्मक कम खर्च होता है और इसमें असल LCD के मुकाबले ज्यादा कॉन्ट्रास्ट मिलता है। वहीं TFT LCD में नुकसान ये है कि इन्हें रेगुलर LCD प्रकारों के मुकबाले ज्यादा एनर्जी यानि बैटरी चाहिए, इनके व्यूिंग एंगल और रंग भी इतने अच्छे नहीं होते। इन्हीं सब कारणों से बाकी डिस्प्ले विकल्पों की गिरती कीमतों के कारण अब TFT डिस्प्ले का इस्तेमाल स्मार्टफोनों में नहीं किया जाता।

TFT(Thin Film Transistor) – ये भी LCD डिस्प्ले का ही एक प्रकार है जिसमें नीचे एक पतली सेमीकंडक्टर की परत होती है जो हर एक पिक्सल पर रंगों को नियंत्रित करने का काम करता है। इसका और AMOLED में आने वाले AM यानि कि active matrix का काम लगभग एक ही है।

LTPS(Low Temperature PolySilicon) – ये भी Si (amorphous silicon) तकनीक पर आधारित TFT का ही वैरिएंट है जिसमें आपको हाई रेज़ॉल्यूशन मिलता है और ऊर्जा यानि कि पॉवर साधारणत: TFT से कम लेता है।

IGZO(Indium Gallium Zinc Oxide) – ये भी एक सेमिकंडक्टर मैटेरियल है जो डिस्प्ले के नीचे लगी फिल्म में इस्तेमाल होता है और आजकल a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays

PLS (Plane to Line Switching) – PLS और IPS के नाम या उनके फुल फॉर्म लगभग एक ही जैसे लगते हैं। लेकिन इसमें आश्चर्य की कोई बात नहीं है क्योंकि इनका मुख्य कार्य भी एक समान ही है। PLS टेक्नोलॉजी को Samsung Display द्वारा बनाया गया है और IPS डिस्प्ले की ही तरह इसकी विशेषता भी डिस्प्ले पर अच्छे रंग दर्शाना और बेहतर व्यूइंग एंगल दिखाना ही हैं। लेकिन इसमें OLED और LCD/VA डिस्प्ले के मुकाबले कॉन्ट्रास्ट थोड़ा कम है।

Samsung Display का कहना है कि PLS पैनलों के उत्पादन में लागत कम लगती है, ब्राइटनेस लेवल अच्छा मिलता है और प्रतियोगी कंपनी LG Display के IPS पैनलों के मुकाबले व्यूइंग एंगल भी काफी अच्छे मिलते हैं। अंतत: PLS पैनल का उपयोग किया जाए या IPS पैनल का इस्तेमाल करें, ये पूरी तरह से स्मार्टफोन निर्माताओं पर निर्भर करता है।

AMOLED की फुल फॉर्म – एक्टिव मैट्रिक्स ऑर्गेनिक लाइट एमिटिंग डायोड (Active Matrix Organic Light-Emitting Diode) है। हालांकि ये सुनने में बहुत मुश्किल नाम लग रहा होगा, लेकिन ये है नहीं। हम पहले ही TFT LCD टेक्नोलॉजी में एक्टिव मैट्रिक्स के बारे में पढ़ चुके हैं और अब रहा OLED, तो ये केवल एक पतली फिल्म वाली डिस्प्ले तकनीक है और कुछ नहीं।

और क्योंकि OLED डिस्प्ले में काले पिक्सल बंद हो जाते हैं, उनमें करंट नहीं आता, इसीलिए कॉन्ट्रास्ट लेवल भी LCD डिस्प्ले के मुकाबले ज्यादा मिलता है। AMOLED डिस्प्ले में रिफ्रेश रेट तो ज़्यादा मिल जाता है, लेकिन वहीँ LCD डिस्प्ले को, AMOLED की तुलना में ज्यादा ब्राइट बनाया जा सकता है। क्योंकि ये एक ऑर्गेनिक मैटीरियल से बने होते हैं, एक लम्बे समय के इस्तेमाल के बाद इनकी ब्राइटनेस घटने लगती है जिससे कई बार स्क्रीन बर्न-इन जैसी समस्याएं भी आ सकती हैं। हालाँकि ये समस्या पुराने स्मार्टफोनों में ज्यादा आती थी, अब ऐसा ना के बराबर होता है।

वहीँ इसकी अच्छी बात ये है कि AMOLED डिस्प्ले LCD के मुकाबले पतली होती हैं क्योंकि इनमें अंदर बैकलिट की परत लगाने की ज़रुरत नहीं पड़ती और इन्हें फ्लेक्सिबल यानि कि लचीला भी बनाया जा सकता है।

OLED को- Organic Light Emitting Diode कहते हैं। एक OLED डिस्प्ले electroluminescent मैटीरियल की पतली शीट से बनी होती है, जिसका सबसे बड़ा फायदा यही है कि ये अपनी रौशनी खुद पैदा करते हैं और इन्हें बैकलाइट की ज़रुरत नहीं पड़ती, जिससे ऊर्जा या बिजली की ज़रुरत कम पड़ती है। यही OLED स्क्रीन जब स्मार्टफोन या टीवी के लिए उपयोग होती है तो इसे ज़्यादातर AMOLED डिस्प्ले के नाम से जाना जाता है।

जैसे कि हमने पहले भी बताया AMOLED में AM एक्टिव मैट्रिक्स (Active Matrix) के लिए इस्तेमाल होता है। हालाँकि ये पैसिव मैट्रिक्स (Passive Matrix) OLED से अलग होता है जिसे p-OLED कहा जाता है। ये स्मार्टफोनों में थोड़ा कम प्रचलित है।

वहीं Super AMOLED, दक्षिणी कोरियाई कंपनी Samsung द्वारा दिया गया है एक नाम है जो अब कंपनी के मिड-रेंज से प्रीमियम रेंज के स्मार्टफोनों में देखने को मिलता है। IPS LCD की ही तरह, Super AMOLED डिस्प्ले में साधारण AMOLED डिस्प्ले पर टच रिस्पांस लेयर को जोड़कर एक किया जाता है, इसमें अलग से एक परत नहीं लगाई जाती। और इसका नतीजा ये होता है कि Super AMOLED स्क्रीन सूरज की रौशनी या आउटडोर में AMOLED के मुकाबले बेहतर नज़र आती हैं और साथ ही ये पावर भी कम लेती हैं।

जैसे कि Samsung ने इस स्मार्टफोन डिस्प्ले टाइप का नाम -Super AMOLED रखा है। साधारण भाषा में ये AMOLED स्क्रीन का सुधार किया गया या कहें कि बेहतर वर्ज़न है। और ये केवल मार्केटिंग के लिए मारने वाली डींगें नहीं हैं, बल्कि कई उत्पादों की समीक्षा (review) करने बाद, तथ्य यही है कि Samsung की डिस्प्ले बाज़ार में सबसे उत्तम श्रेणी में आती हैं।

वहीँ इसकी तकनीक में किये गए सबसे नए विकास या सुधार को कंपनी ने Dynamic AMOLED का नाम दे दिया। . हालांकि Samsung ने इसके बारे में कभी विस्तार से नहीं बताया है लेकिन इतना साफ़ कर दिया है कि इस तरह की डिस्प्ले में HDR10+ सर्टिफिकेशन शामिल होता है जिसके साथ आपको स्क्रीन पर रंगों और कॉन्ट्रास्ट की एक वाइड रेंज मिलती है। साथ ही इसमें ब्लू लाइट कम होती जिससे ये डिस्प्ले आँखों के लिए ज्यादा आरामदायक हो।

ठीक इसी तरह OnePlus ने भी हाई-एंड स्मार्टफोनों के लिए नाम रखा है – Fluid AMOLED, जिसमें हाई रिफ्रेश रेट ही इसकी ख़ास बात है, इसमें कोई और अंतर नहीं होता। उदाहरण के लिए – डिस्प्ले अगर 120Hz रिफ्रेश रेट के साथ आएगी तो उसमें आपको और ज्यादा स्मूथ एनीमेशन मिलेगा।

पिक्सल डेंसिटी की बात करें तो, 2010 में iPhone 4 के लॉन्च के समय Apple का मुख्य आकर्षण यही था। इस स्मार्टफोन डिस्प्ले में कंपनी ने LCD डिस्प्ले का इस्तेमाल किया। इस LCD पैनल ((LED, TFT, और IPS) को हाई रेज़ॉल्यूशन (उस समय पर 960 X 640 पिक्सल्स) के साथ Retina Display का नाम दिया। इस फ़ोन में 3.5 इंच की डिस्प्ले थी।

उस समय पर Apple के मार्केटिंग डिपार्टमेंट ने Retina Display नाम इसलिए चुना क्योंकि कंपनी के अनुसार एक निश्चित दूरी से हमारी या किसी भी इंसान की आंखें अलग-अलग पिक्सल में फर्क नहीं कर पाती। iPhones के केस में, ये नाम तब इस्तेमाल होता था जब फ़ोन की डिस्प्ले पर 300 ppi (pixel per inch) से ज्यादा होती थी।

जब सबने हाई रेज़ॉल्यूशन के साथ डिस्प्ले लेना आरम्भ कर दिया, फिर Apple ने खुद को भीड़ में अलग करने के लिए अपने प्रीमियम स्मार्टफोनों में इस्तेमाल होने वाली OLED डिस्प्ले को “Super Retina” का नाम दे दिया। ये डिस्प्ले iPhone X और उसके बाद आने वाले फोनों में आयी है। ये डिस्प्ले हाई कॉन्ट्रास्ट रेट और डिस्प्ले पर रंगों की सटीकता के लिए जानी जाती है, और ऐसी ही स्क्रीन Samsung के S-सीरीज़ के स्मार्टफोनों में भी आप देख सकते हैं।

इसके बाद कंपनी ने iPhone 11 Pro के साथ डिस्प्ले का नया नाम भी लॉन्च किया – “Super Retina XDR”। इसमें भी वही OLED पैनल का उपयोग किया गया है, लेकिन इसे पैनल का निर्माण Samsung Display या LG Display द्वारा हुआ है। इसमें आपको 2,000,000:1 रेश्यो के साथ और भी बेहतर कॉन्ट्रास्ट लेवल और 1200 nits की ब्राइटनेस मिलते हैं और ये ख़ासकर HDR कंटेंट के लिए अनुकूल हैं।

साथ ही दूसरी चुनौती ये है कि इनकी कीमत भी काफी ज्यादा होती है। उदाहरण के लिए – Samsung की microLED TVs (146 इंच से 292 इंच) की कीमत 3.5 करोड़ से 12 करोड़ है, जो कि बहुत ही ज़्यादा है।

जैसे कि हमने पहले भी कहा, OLED या AMOLED डिस्प्ले में सबसे बड़ा फ़ायदा है कि हर पिक्सल खुद को रौशनी देने का कार्य संभालता है और इससे कंट्रास्ट लेवल बढ़ता है। साथ ही दूसरा फ़ायदा है ज़्यादा और सटीक काला रंग, जो कि डिस्प्ले पर देखते समय अच्छी पिक्चर क्वालिटी के लिए बेहद महत्वपूर्ण है। साथ ही जिस समय स्क्रीन कोई गहरे (डार्क) रंग की तस्वीर दिखाती है तो ये ये ऊर्जा भी कम लेते हैं।

वहीँ इनकी ख़ामियों की बात करें तो, इनको बनाने में काफी ज़्यादा लागत लगती है और कॉम्पोनेन्ट की पूर्ती करने वाली कंपनियां भी सीमित ही हैं। इनमें Samsung Display, LG Display और तीसरे नंबर पर चीन की इलेक्ट्रॉनिक्स कंपनी BOE और कुछ एक जो OLED की मांग को पूरा करते हैं। जबकि LCD पैनल बनाने वाली काफी कम्पनियां हैं।

Over time, the purpose of using mobile phones or Smartphones has changed. Comparatively, it has now become a basic necessity of every individual. Smartphone has dramatically transformed the lives of individuals. It has now become a mini-computer that everyone carries in their pocket. Instead, you can have multiple things at your fingertips in a few seconds. While there are plenty of things to look for, AMOLED vs OLED is also a part of it.

Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, we have brought a comprehensive study of the significant display technologies available nowadays.

This article will introduce you to AMOLED vs OLED display technologies. Then, we will discuss the properties of both display technologies, followed by the difference between AMOLED vs OLED.

It stands for Natural Light-Emitting Diode, a type of LED technique that utilises LEDs wherein the light is of organic molecules that cause the LEDs to shine brighter. These organic LEDs are in use to make what are thought to be the best display panels in the world.

When you make an OLED display, you put organic films among two conductors to make them. As a result, a bright light comes out when electricity is used—a simple design with many advantages over other ways to show things.

OLEDs can be used to make emissive displays, which implies that each pixel can be controlled and emits its very own light. As a result, OLED displays have excellent picture quality. They have bright colours, fast motion, and most importantly, very high contrast. Most of all, “real” blacks are the most important.  The simple design of OLEDs also makes it easy to create flexible displays that can bend and move.

PMOLED stands for Passive Matrix Organic Light Emitting Diode. The PMOLEDs are easy to find and much cheaper than other LEDs, but they cannot work for a long duration as their lifespan is very short. Therefore, this type of display is generally for small devices up to 3 inches.

AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display is generally for large platforms. It contains TFT, which further consists of a storage capacitor. It also works on the same principle as OLED displays.

AMOLED offers no restriction on the size of the display. The power consumption of AMOLED is much less than other display technologies. The AMOLED provides incredible performance. It is thinner, lighter, and more flexible than any other display technology like LED, or LCD technology.

The AMOLED display is widely used in mobiles, laptops, and televisions as it offers excellent performance. Therefore, SAMSUNG has introduced AMOLED displays in almost every product. For example, Full HD Super AMOLED in Samsung Galaxy S4 and Samsung Galaxy Note 3, Super AMOLED in Samsung Galaxy S3, HD Super AMOLED in Samsung Galaxy Note, and HD Super AMOLED Plus in Samsung Galaxy S3. Apart from this, it is also used in AMOLED vs OLED creating the following:

So far, we have discussed OLED and AMOLED display technologies. Now, we will look at some of the differences between OLED and AMOLED display technology:

OLED comprises thin layers of the organic component, which emits light when the current passes through it. In this technology, each pixel transmits its own light. On the other side, AMOLED consists of an additional layer of thin-film transistors (TFTs). In AMOLED, the storage capacitors are used to maintain the pixel states.

While the technology is different among various manufacturers, Samsung’s edge AMOLED displays use plastic substrates with poly-Si TFT technology similar to how LG uses it in their POLED technology. This technology is what makes the possibility to build curved displays using an active-matrix OLED panel.

OLED display much deeper blacks as compared to the AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight. The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.

These organic compounds are present between the protective layers of glass or plastic. Comparatively, AMOLED comprises an active matrix of OLED pixels along with an additional layer of TFTs. This extra layer is responsible for controlling the current flow in each pixel.

The OLED display offers a high level of control over pixels. Hence, it can be turned off completely, resulting in an excellent contrast ratio compared to the AMOLED displays and less power consumption. On the other side, AMOLED has faster refresh rates than OLEDs. Also, they offer a tremendous artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.

OLED displays are comparatively much thinner compared to the LCDs. Hence, it provides more efficient and bright presentations. In addition, OLED offers support for large display sizes compared to the traditional LCDs. AMOLEDs remove the limitation of display sizes. one can fit it into any display size.

Putting all the points mentioned above in view, the key difference to understand appropriately is that POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is Samsung’s word for its display technology which is mainly for marketing. Therefore, most phone manufacturers having AMOLED displays mean that they are using Samsung displays. It is as simple as that. To add to that, all the curved display technology is made possible because of the usage of plastic substrate.

So, based on the points mentioned above, the difference between OLED and AMOLED displays, you can choose any of the two display technology at your convenience. Both are good, offer excellent performance, and are customised according to your requirements.

The AMOLED display has a higher quality than OLEDs since it has an additional layer of TTs and uses backplane technologies. When compared to OLED screens, AMOLED displays are far more flexible. As a result, they are substantially more expensive than an OLED display.

Window to the digital world, the display is one of the first seen features when selecting a smartphone, so a show must be good, and an AMOLED display offers the same. Offering a great viewing experience, here are the top 3 AMOLED screen smartphones available in the market right now:

Since it comes with an FHD+ curved AMOLED display on the display front, it is a treat for gamers and media consumption lovers.

Smartphone displays have advanced significantly in recent years, more so than most people realise in this technological age. Display screens are similar to windows in the mobile world, which has seen a tremendous transformation in innovative products in the last several years. People have gotten more selective when buying a phone in recent years, and although all of the functions are important, the display is always the most noticeable.

Major smartphone manufacturers attempt to provide their consumers with the most delicate devices possible that incorporate the most up-to-date technologies. In AMOLED vs OLED, AMOLED is a type of OLED and a more prominent example of both OLED and POLED, so there’s no debate about which is superior.

AMOLED (active-matrix organic light-emitting diode, OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for passive-matrix OLED operation.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays.

AMOLED was developed in 2006. Samsung SDI was one of the main investors in the technology, and many other display companies were also developing it. One of the earliest consumer electronics products with an AMOLED display was the BenQ-Siemens S88 mobile handsetiriver Clix 2 portable media player.Nokia N85 followed by the Samsung i7110 - both Nokia and Samsung Electronics were early adopters of this technology on their smartphones.

Manufacturers have developed in-cell touch panels, integrating the production of capacitive sensor arrays in the AMOLED module fabrication process. In-cell sensor AMOLED fabricators include AU Optronics and Samsung. Samsung has marketed its version of this technology as "Super AMOLED". Researchers at DuPont used computational fluid dynamics (CFD) software to optimize coating processes for a new solution-coated AMOLED display technology that is competitive in cost and performance with existing chemical vapor deposition (CVD) technology. Using custom modeling and analytic approaches, Samsung has developed short and long-range film-thickness control and uniformity that is commercially viable at large glass sizes.

The amount of power the display consumes varies significantly depending on the color and brightness shown. As an example, one old QVGA OLED display consumes 0.3 watts while showing white text on a black background, but more than 0.7 watts showing black text on a white background, while an LCD may consume only a constant 0.35 watts regardless of what is being shown on screen.

AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.Super AMOLED technology addresses this issue by reducing the size of gaps between layers of the screen.PenTile technology is often used for a higher resolution display while requiring fewer subpixels than needed otherwise, sometimes resulting in a display less sharp and more grainy than a non-PenTile display with the same resolution.

The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.

As of 2010, demand for AMOLED screens was high and, due to supply shortages of the Samsung-produced displays, certain models of HTC smartphones were changed to use next-generation LCD displays from the Samsung-Sony joint-venture SLCD in the future.

Flagship smartphones sold in 2020 and 2021 used either a Super AMOLED. Super AMOLED displays, such as the one on the Samsung Galaxy S21+ / S21 Ultra and Samsung Galaxy Note 20 Ultra have often been compared to IPS LCDs, found in phones such as the Xiaomi Mi 10T, Huawei Nova 5T, and Samsung Galaxy A20e.ABI Research, the AMOLED display found in the Motorola Moto X draws just 92 mA during bright conditions and 68 mA while dim.

"Super AMOLED" is a marketing term created by Samsung for an AMOLED display with an integrated touch screen digitizer: the layer that detects touch is integrated into the display, rather than overlaid on top of it and cannot be separated from the display itself. The display technology itself is not improved. According to Samsung, Super AMOLED reflects one-fifth as much sunlight as the first generation AMOLED.One Glass Solution (OGS).

Future displays exhibited from 2011 to 2013 by Samsung have shown flexible, 3D, transparent Super AMOLED Plus displays using very high resolutions and in varying sizes for phones. These unreleased prototypes use a polymer as a substrate removing the need for glass cover, a metal backing, and touch matrix, combining them into one integrated layer.

Also planned for the future are 3D stereoscopic displays that use eye-tracking (via stereoscopic front-facing cameras) to provide full resolution 3D visuals.

The world of smartphones has been busy for the past few months. There have been numerous revolutionary launches with groundbreaking innovations that have the capacity to change the course of the smartphone industry. But the most important attribute of a smartphone is the display, which has been the focus for all prominent players in the mobile phone industry this year.

Samsung came up with its unique 18:5:9 AMOLED display for the Galaxy S8. LG picked up its old trusted IPS LCD unit for the G6’s display. These display units have been familiar to the usual Indian smartphone buyer. Honor, on the other hand, has just unveiled the new Honor 8 Pro for the Indian market that ships with an LTPS LCD display. This has led to wonder how exactly is this technology different from the existing ones and what benefits does it give Honor to craft its flagship smartphone with. Well, let’s find out.

The LCD technology brought in the era of thin displays to screens, making the smartphone possible in the current world. LCD displays are power efficient and work on the principle of blocking light. The liquid crystal in the display unit uses some kind of a backlight, generally a LED backlight or a reflector, to make the picture visible to the viewer. There are two kinds of LCD units – passive matrix LCD that requires more power and the superior active matrix LCD unit, known to people as Thin Film Transistor (TFT) that draws less power.

The early LCD technology couldn’t maintain the colour for wide angle viewing, which led to the development of the In-Plane Switching (IPS) LCD panel. IPS panel arranges and switches the orientation of the liquid crystal molecules of standard LCD display between the glass substrates. This helps it to enhance viewing angles and improve colour reproduction as well. IPS LCD technology is responsible for accelerating the growth of the smartphone market and is the go-to display technology for prominent manufacturers.

The standard LCD display uses amorphous Silicon as the liquid for the display unit as it can be assembled into complex high-current driver circuits. This though restricts the display resolution and adds to overall device temperatures. Therefore, development of the technology led to replacing the amorphous Silicon with Polycrystalline Silicon, which boosted the screen resolution and maintains low temperatures. The larger and more uniform grains of polysilicon allow faster electron movement, resulting in higher resolution and higher refresh rates. It also was found to be cheaper to manufacture due to lower cost of certain key substrates. Therefore, the Low-Temperature PolySilicon (LTPS) LCD screen helps provide larger pixel densities, lower power consumption that standard LCD and controlled temperature ranges.

The AMOLED display technology is in a completely different league. It doesn’t bother with any liquid mechanism or complex grid structures. The panel uses an array of tiny LEDs placed on TFT modules. These LEDs have an organic construction that directly emits light and minimises its loss by eradicating certain filters. Since LEDs are physically different units, they can be asked to switch on and off as per the requirement of the display to form a picture. This is known as the Active Matrix system. Hence, an Active Matrix Organic Light Emitting Diode (AMOLED) display can produce deeper blacks by switching off individual LED pixels, resulting in high contrast pictures.

The honest answer is that it depends on the requirement of the user. If you want accurate colours from your display while wanting it to retain its vibrancy for a longer period of time, then any of the two LCD screens are the ideal choice. LTPS LCD display can provide higher picture resolution but deteriorates faster than standard IPS LCD display over time.

An AMOLED display will provide high contrast pictures any time but it too has the tendency to deteriorate faster than LCD panels. Therefore, if you are after greater picture quality, choose LTPS LCD or else settle for AMOLED for a vivid contrast picture experience.

Advancements in technology have led to better, brighter display systems, redefining our experience of viewing content. Better picture quality and crystal-clear images are some of the benefits of new displays such as AMOLED and IPS LCD

When choosing which television or mobile phone to buy, it’s essential to consider the display quality and technology. Here are the differences between Super AMOLED and IPS LCD screens, two of the forerunners in display technology, and an analysis of which one of the two is better.

LCD, short for liquid crystal display, has a flat panel display. It is an electronically controlled optical device that uses the liquid crystals" light-modified properties along with polarisers. The liquid crystals do not directly emit light. Hence, a reflector and a backlight generate images either in monochrome or colour. An LCD blocks the light instead of emitting it and is used more widely in televisions and basic smartphones. IPS, which stands for in-plane switching, is a screen technology for LCD.

AMOLED is short for Active Matrix Organic Light-Emitting Diodes. This type of OLED is usually incorporated in flagship smartphones and modern televisions. It uses the latest technology of a particular type of thin display. The organic compounds present in it produce electroluminescent material.

The active matrix comes from the technology that addresses the pixels effectively. Super AMOLED contains integrated touch functionality. It exhibits a variety of colours and has exceptional clarity, translating into superior resolution.

AMOLED has a thinner film transistor fixed to every LED alongside a capacitor. AMOLED and IPS LCD screens are made using three pixels—red, blue, and green. LCDs generate light through a backlight. With AMOLED displays, every pixel has a separate light source, eliminating the need for a backlight. As a result, the display assembly is thinner and provides consistent lighting throughout the complete screen.

Each of these displays has its specialities. Nevertheless, if we compare Super AMOLED display vs IPS LCD, the former is better because it integrates the latest technologies and has excellent performance.

Both screens are made up of Pixels. A pixel is made up of 3 sections called sub-pixels. The three sections are red, green and blue (primary colors for display tech).

The light is generated from a “backlight”. A series of thin films, transparent mirrors and an array of white LED Lights that shine and distribute light across the back of the display.

On some lower quality LCD screens, you can see bright spots in the middle or on the perimeters of screens. This is caused by uneven light distribution. The downside to using backlights, is that black is never true black, because no matter what, light has to be coming through, so it will never have as dark of a screen as an AMOLED screen. Its comparable to being able to slow a car down to 2 mph versus coming to a complete stop.

Each pixel is its own light source, meaning that no backlight is necessary. This allows the screen assembly to be thinner, and have more consistent lighting across the whole display.

OLED displays have become increasingly common and accessible over the past few years. While they were once reserved for premium smartphones, you’ll now find OLED displays at every smartphone price point. Not every OLED display is equal, though – differences in materials and manufacturing processes can result in varying display qualities. In that vein, let’s explore the differences between POLED vs AMOLED, and what these acronyms mean in the real world.

Before differentiating between POLED and AMOLED, it’s worth understanding the fundamentals of OLED display technology. To that end, let’s ignore the P and AM prefixes for now.

If you look at an OLED display under a microscope, you’ll see these diodes arranged in various red, green, and blue configurations in order to produce a full range of colors. OLED has a key advantage over conventional LCDs – individual light emitters can be switched completely off. This gives OLED deep blacks and an excellent contrast ratio.

Naturally, light emitters in an OLED display need a power source in order to function. Manufacturers can use either a passive wiring matrix or an active wiring matrix. Passive matrix displays provide current to an entire row of LEDs, which isn’t ideal but it is cheap. An active matrix, on the other hand, introduces a capacitor and thin-film transistor (TFT) network that allows each pixel to be driven individually. This driving matrix is part of the panel that sits on top of a base substrate.

Today, virtually all high-resolution OLED displays use active-matrix technology. This is because a passive matrix requires higher voltages the more pixels you introduce. High voltage reduces LED lifetimes, making a passive matrix OLED impractical.

AMOLED simply refers to an Active Matrix OLED panel. The AMOLED branding has become synonymous with Samsung Display’s OLED panels over the years. However, all smartphone OLED panels, including those from Samsung’s rivals like LG Display use active-matrix technology too – they just aren’t marketed as such.

In case you’re wondering what Super AMOLED means, it’s another bit of branding to indicate the presence of an embedded touch-sensitive layer. Similarly, Dynamic AMOLED refers to a display with HDR capabilities, specifically support for Samsung’s favored HDR10+ standard.

Now that we know the layered structure of an OLED display, we can move on to the plastic part. While the first wave of OLED panels was built using glass substrates, the desire for more interesting form factors has seen manufacturers use more flexible plastic components. This is where the P in POLED comes from.

Manufacturers have experimented with a range of plastics for flexible displays, including polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). OLED manufacturers have settled on using polyimide plastics (PI) that can better withstand high TFT manufacturing temperatures. The type of substrate and heating process used also defines the flexibility of the display.

The somewhat confusing part is that Samsung’s AMOLED displays use plastic substrates. And as the name suggests, LG Display’s POLED technology clearly uses plastic as well. In summary, it’s absolutely possible to build a plastic substrate, active-matrix OLED panel. That’s exactly what both of the big two panel manufacturers are doing when it comes to mobile displays.

Even though LG and Samsung-made OLED panels qualify as both POLED and AMOLED simultaneously, the companies aren’t exactly producing identical panels. The quality of the TFT layer and plastic compound can make a difference to display performance, as can the type of emitters and sub-pixel layout.

Over the years, we’ve seen OLED display manufacturers converge on a set of standard parameters. For example, both LG and Samsung use a diamond PenTile sub-pixel layout for smartphone displays. This just means that both should offer similar long-term reliability.

Even when it comes to other attributes like power consumption, brightness, low brightness performance, and panel uniformity, it’s unclear if one has an upper hand. That said, most smartphone makers — from Apple to OnePlus — turn to Samsung’s AMOLED panels for their flagship devices.

In the past, LG used POLED displays in its own flagship smartphones like the Velvet and Wing. However, these panels fell slightly short of the competition in certain aspects like peak brightness and color gamut coverage. These shortfalls led to speculations that Samsung has a leg up over the competition, but the accuracy of these claims is anyone’s guess.

So does that mean you should avoid POLED? Not quite — it’s still fundamentally OLED technology, which offers numerous advantages over IPS LCD. Moreover, you’ll mostly find POLED displays in mid-range and budget smartphones these days, where they should have no problem matching Samsung’s own lower-end AMOLED panels. As a relatively smaller player, LG may also offer more competitive pricing as compared to Samsung.

For most consumers, the choice of POLED vs AMOLED will be of little consequence. The underlying principle – an active-matrix OLED on a flexible plastic substrate – applies equally to both, after all. Despite the different names, LG Display and Samsung aren’t worlds apart in their approach to producing OLED panels for smartphones.

देखा जाये तो मार्केट में इस समय तीन तरह की डिसप्ले स्क्रीन ज्यादा मौजूद है, TFT, IPS और Super Amoled. लेकिन कई बार लोगों को ये पता ही नहीं होता है, कि कौन सी स्क्रीन सबसे बेस्ट है और वो कौन सा मोबाइल खरीदें।

इसलिए आज हम आपको TFT, IPS और Super Amoled डिसप्ले स्क्रीन के बारे में बताने जा रहे हैं। ताकि आप यह जान सके कि, कौन सी स्क्रीन है सबसे बेस्ट TFT, IPS और Super AMOLED. तो चलिए जान लेते है की, ips tft vs super amoled display which is better in hindi.

कौन सी स्क्रीन है सबसे बेस्ट TFT, IPS और Super AMOLED. चलिए एक एक करके हम लोग जान लेते है की, इन तीनो डिस्प्ले में से कौन सबसे अच्छा है। ताकि आप आसानी से यह जान सके की, कौन सी डिस्प्ले स्क्रीन वाली फ़ोन खरीदना चाहिए।

पहले के फोन में टीएफटी डिसप्ले देखने को मिलता है। ज्यादातर सस्ते और एंट्री लेवल फोन में TFT डिसप्ले लगा होता है। यह डिस्प्ले काफी सस्ता तो जरुर है। लेकिन क्वालिटी के मामले में, यह बिलकुल भी अच्छी नहीं होता है।

देखा जाये तो IPS एलसीडी और Super Amoled डिसप्ले, दोनों का ही क्वालिटी बहुत बढ़िया होता हैं। लेकिन फिर भी दोनों में काफी फर्क है। जहा IPS एलसीडी डिसप्ले थोड़ा मोटा होता है। तो वहीं Super Amoled डिसप्ले काफी पतला होता है, और इनके फोन भी पतले आते हैं।

लेकिन इसी कारण IPS एलसीडी में फोन की बैटरी भी जल्दी डाउन हो जाती है। क्योंकि जब फोन की स्क्रीन ऑन होता है। तो IPS एलसीडी भी सारी ऑन रहती है। जिसके कारण ज्यादा पावर का यूज होता है और बैटरी जल्दी डाउन हो जाता है। लेकिन वहीं दुसरी और Super Amoled display में ऐसा नहीं होता है।

सुपर एमोलेड डिसप्ले ज्यादातर हाई बजट के फोन में आते है। इसीलिए Super Amoled डिसप्ले के लिए, आपको थोड़ा महंगा फोन खरीदना पड़ेगा। सुपर एमोलेड डिसप्ले में कलर आखों के लिए अच्छे होते हैं और पिक्चर में मौजूद सभी कलर नैचुरल नजर आते हैं।

Super Amoled में IPS एलसीडी से ज्यादा चमक होती है। Super amoled screen के साथ आने वाले स्मार्टफोन की बैटरी लाइफ भी अच्छी होती है। क्योंकि फोन का सिर्फ उतना ही स्क्रीन ऑन रहता है। जितने में कलर नजर आते है। जैसे अगर आप के फ़ोन स्क्रीन पर डार्क कलर का इमेज है। तो फोन बहुत कम पावर लेगा।

आशा करता हु दोस्तों “TFT, IPS aur Super Amoled display me kaun hai sabse best”, अब आप को पता चल गया होगा। और अब आप अपने जरुरत के हिसाब से एक अच्छा डिस्प्ले स्क्रीन वाला फ़ोन ख़रीद पायेगे।
