tft display vs amoled in hindi supplier

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.

There is a constant debate on Amoled vs LCD, which is a better display? Where Amoled display offers some remarkable colors with deep black eye-soothing contrast ratio, LCD displays offer much more subtle colors with better off-axis angles for viewing & offers a much brighter picture quality.

While purchasing a new smartphone we consider various specifications like software, camera, processor, battery, display type etc. Among all the specifications display is something that most people are concerned about. 2 of the major competitors of smartphone display are AMOLED and LCD. Often in the LCD vs Amoled comparison, people get confused about which one to choose. In this article, we have explained a clear comparison of the Amoled vs LCD screen to find out which is actually better.

Amoled display is nothing but a part of OLED display which comes with some extra features. The first component is Light Emitting Diode (LED) and the second component is "O", here "O" stands for organic & together they make OLED. The real meaning derived from it is organic material placed with 2 conductors in every LED. And this is how light is produced.

The OLED display can generate light out of individual pixels. AMOLED displays contain Thin Film Translator (TLT) which makes the overall procedure of sourcing current to the correct pixel much quicker and smoother. The TXT further helps grab control for operating different pixels at a time. For example, some pixels could be absolutely switched off though others remain on in Amoled displays. This produces a deep black color.

Speaking about LCDs, it is relatively pretty much commonly found in today"s smartphones. LCD (Liquid Crystal Display) offers a devoted black light that is white or rather slightly blueish in color. Mostly here we get a blue light that is passed through some yellowish phosphor filter which brings out the white light. The white light is subsequently passed through multiple filters and thereafter the crystal elements are again passed through blue, red & green filters. Note that LCD displays have both passive and active matrix which depends on the cost and requirement involved.

Since the process involved in LCDs is much more complex than Amoled & requires extra steps, when compared to AMOLED displays, LCDs are less battery friendly. In the technological era where energy efficiency is the first priority, Amoled displays are certainly going to be the future of display technology. But both of them come with a separate set of pros and cons and it is only by knowing the pros and cons you will be able to choose the right one.

Amoled display technology is mostly used in smartphones, media players & digital cameras. Amoled is mostly used in low power, cost-effective & large application sizes.

Cost is one of the major factors that act as a differentiator between the two display types. Amoled displays are comparatively more expensive than LCD displays because LCD displays are much cheaper to manufacture. So while buying a low-budget smartphone, the probability to get a Amoled display is pretty less.

The quality of a display is mainly measured according to the colors and sharpness it offers. Also while comparing two displays, only technology comparison won"t work because often displays behave inversely even if a manufacturer is using the very same technology. If you consider colors especially contrasting colors such as blue, red or green, Amoled will serve better throughout the day. This happens mainly because in the case of AMOLED displays, as mentioned above, every pixel present in it emit its own light whereas in LCD light comes out of the backlight. Therefore Amoled displays offer high-end saturation and vibrant colors compared to LCD displays.

As Amoled displays put out vibrant colors, you will find Amoled displays to be warmer in nature compared to LCD displays which has a more neutral whitish tint. In short, the pictures seen on Amoled displays are more eye-soothing compared to LCD displays where the pictures appear more natural.

In the Amoled vs LCD screen display comparison, another thing to consider is the brightness offered by both of them. Compared to LCD displays, Amoled displays have lesser brightness levels. This is mainly because of the backlight in LCD displays which emits a higher brightness level. Therefore if you are a person who spends most of the time outdoors and mostly uses your smartphone under the sun, then LCD is the right choice for you. Although certain leading brands are working on the brightness level in Amoled displays.

The display is one such thing that sucks your phone"s battery to a great extent. In Amoled displays, the pixels can get absolutely switched off thereby saving a lot of battery. Whereas LCD displays remain dependent on the back light, as a result even if your screen is completely black, the backlight remain switched on throughout. This is why even though Amoled displays are more expensive than LCD displays as they consume much less battery than LCD displays.

In the battle between LCD display vs Amoled display both come with separate pros and cons. Well if battery consumption and color contrast or saturation is a concern then the Amoled display is going to win over LCD display anyway. While purchasing a smartphone, customers today mainly focus on two features- lesser battery consumption and a high-quality display. Amoled display offers both the benefits- high-end vibrant display and less battery consumption. The only criteria where LCD displays win over Amoled is the brightness level. But with brands coming with the latest technologies, Amoled is certainly going to catch up with the brightness level with LCD displays. Also, the brightness difference in current Amoled display smartphones that are available in the market is hardly noticeable.

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.

The OLED devices are simple solid-state devices consisting of a thin layer of organic compounds in an emissive electroluminescent layer where the electricity generates.

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:

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.

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 ?

अगर संक्षिप्त रूप से और आसान भाषा में समझें तो दो तरह की टेक्नोलॉजी- एलसीडी (LCD) और ओलेड (OLED) बाज़ार में आ रहीं हैं। प्रत्येक में कुछ विभिन्न प्रकार और जनरेशन हैं जो बाकी के स्क्रीन टाइप शार्ट फॉर्म को बनाती हैं। इसी तरह टेलीविज़न की दुनिया में भी अलग स्क्रीन टाइप उपलब्ध हैं जैसे कि LED, QLED, miniLED – ये सब दरसअल एलसीडी (LCD) तकनीक के ही अलग अलग रूप हैं जिनमें थोड़ी विविधताएं हैं।

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

LTPO( Low Temperature Polycrystaline Oxide) – इस टेक्नोलॉजी को Apple ने डेवेलप किया है और इसे वर्तमान समय में OLED और LCD दोनों तरह की स्क्रीन में इस्तेमाल किया जाता है। इसमें LTPS और IGZO दोनों तकनीकों का इस्तेमाल मिलाकर किया जाता है और नतीजा होता है – डिस्प्ले द्वारा पॉवर का कम इस्तेमाल। ये Apple Watch 4 और Galaxy S21 Ultra में आयी है।

IPS तकनीक को In-Plane Switching तकनीक कहते हैं। IPS टेक्नोलॉजी ने सबसे पहले आयी LCD डिस्प्ले में आने वाली समस्या को दूर किया जिसमें TN तकनीक का इस्तेमाल होता था और इसमें साइड से देखने पर रंग बहुत ख़राब नज़र आते थे। ये कमी ज़्यादातर सस्ते स्मार्टफोन और टैबलेटों में नज़र आया करती थी।

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।

तब से, अन्य स्मार्टफोन बनाने वाली कंपनियों ने भी यही तरीका अपनाया और हाई रेज़ॉल्यूशन वाले पैनलों को अपनाना शुरू कर दिया। जबकि iPhone 12 Mini में 476 dpi और Sony Xperia 1 में 643 dpi मिलती है।

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।

वहीं iPhone XR और iPhone 11 के ग्राहकों को भी खुश रखने के लिए कंपनी ने इनमें आने वाले LCD पैनल को “Liquid Retina” का नाम दे दिया। बाद में यही डिस्प्ले कंपनी स्टैण्डर्ड के अनुसार बेहतर रेज़ॉल्यूशन और सही रंगों के साथ iPad Pro और iPad Air मॉडल में भी आया।

अंतरराष्ट्रीय प्रणाली या सिस्टम में Nit या कैंडेला प्रति वर्ग मीटर (candela per square meter), जलने या निकलने वाली रौशनी की तीव्रता या गहनता (intensity) को मापने की यूनिट है। अधिकतर स्मार्टफोन, टैबलेट, मॉनिटर के बारे में जब हम बात करते हैं तो ये यूनिट बताती है कि डिस्प्ले कितना ब्राइट है। इसकी वैल्यू जितनी ज्यादा होगा, डिस्प्ले पर पिछले से पड़ने वाली रौशनी की तीव्रता भी उतनी ही ज्यादा होगी।

टेलीविज़न की दुनिया में, miniLED के बारे में हम जान चुके हैं और ये फ़ीचर या तकनीक टीवी में हम देखते ही आ रहे हैं। इसमें बैकलाइट में लाइटिंग ज़ोन का नंबर बढ़ा दिया जाता है। लेकिन अब अफवाहों और कई ख़बरों के अनुसार स्मार्टफोनों और स्मार्टवॉच में भी कंपनियां microLED टेक्नोलॉजी जल्दी ही लेकर आ सकती हैं। ये टेक्नोलॉजी या पैनल LCD/LED से काफी अलग है क्योंकि ये OLED डिस्प्ले की तरह ही बारीकियों के साथ अच्छी पिक्चर क्वॉलिटी देती है।

microLED डिस्प्ले में हर एक सब-पिक्सल में एक अलग रौशनी देने वाला डायोड होता है – अधिकतर ये एक लाल, हरे और नीले डायोड का एक सेट होता है जो एक डॉट के लिए होता है । माना जा रहा है कि microLED में इस बार किसी तरह की अजैविक (inorganic) मैटेरियल का इस्तेमाल होगा जैसे कि gallium nitride (GaN)।

खुद अपनी रौशनी छोड़ने वाला पिक्सल यानि कि self-emitting light जैसी तकनीक अपनाने के साथ, microLED डिस्प्ले में भी बैकलाइट की ज़रूरत नहीं होती। इसमें भी आपको OLED जैसे ही हाई कॉन्ट्रास्ट के साथ पिक्चर देखने को मिलेंगी और साथ ही इसमें ऑर्गेनिक डायोड की तरह स्क्रीन बर्न-इन जैसी समस्याओं का डर भी नहीं है।

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।

इसके अलावा एक और बात जो हम यहां जोड़ना चाहते हैं, समय के साथ OLED स्क्रीन के ऑर्गेनिक डायोड अपनी चमक या कहें कि योग्यता खो देते हैं और ये तब होता है जब एक ही तस्वीर ज्यादा समय तक डिस्प्ले होती है। इसे कपनियां “burn-in” का नाम देती हैं।

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.

Hi all, I"ve done some research on tft vs IPS screens and it seems tft screens are the worst type around. With that said, all the videos and articles I found were from 5ish years ago. Are tft screens still garbage? If so, why in the world would Motorola put it in their flagship?

I have noticed that distributors for small and medium TFT, they consider TFT still a top quality product, it"s enough to see product list of any online distributor like
