Retina Display is a brand name used by Apple for its series of IPS LCD and OLED displays that have a higher pixel density than traditional Apple displays.trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.

The Retina display debuted in 2010 with the iPhone 4 and the iPod Touch (4th Generation), and later the iPad (3rd generation) where each screen pixel of the iPhone 3GS, iPod touch (3rd generation), iPad 2 was replaced by four smaller pixels, and the user interface scaled up to fill in the extra pixels. Apple calls this mode HiDPI mode. In simpler words, it is one logical pixel = four physical pixels. The scale factor is tripled for devices with even higher pixel densities, such as the iPhone 6 Plus and iPhone X.

The Retina display has since expanded to most Apple product lines, such as Apple Watch, iPhone, iPod Touch, iPad, iPad Mini, iPad Air, iPad Pro, MacBook, MacBook Air, MacBook Pro, iMac, and Pro Display XDR, some of which have never had a comparable non-Retina display.marketing terms to differentiate between its LCD and OLED displays having various resolutions, contrast levels, color reproduction, or refresh rates. It is known as Liquid Retina display for the iPhone XR, iPad Air 4th Generation, iPad Mini 6th Generation, iPad Pro 3rd Generation and later versions,Retina 4.5K display for the iMac.

Apple"s Retina displays are not an absolute standard for display sharpness, but vary depending on the size of the display on the device, and at what distance the user would typically be viewing the screen. Where on smaller devices with smaller displays users would view the screen at a closer distance to their eyes, the displays have more PPI (Pixels Per Inch), while on larger devices with larger displays where the user views the screen further away, the screen uses a lower PPI value. Later device versions have had additional improvements, whether an increase in the screen size (the iPhone 12 Pro Max), contrast ratio (the 12.9” iPad Pro 5th Generation, and iMac with Retina 4.5K display), and/or, more recently, PPI count (OLED iPhones); as a result, Apple uses the names “Retina HD display", "Retina 4K/5K display", “Retina 4.5K display", "Super Retina HD display", “Super Retina XDR display”, and "Liquid Retina display" for each successive version.

When introducing the iPhone 4, Steve Jobs said the number of pixels needed for a Retina display is about 300 PPI for a device held 10 to 12 inches from the eye.skinny triangle with a height equal to the viewing distance and a top angle of one degree will have a base on the device"s screen that covers 57 pixels. Any display"s viewing quality (from phone displays to huge projectors) can be described with this size-independent universal parameter. Note that the PPD parameter is not an intrinsic parameter of the display itself, unlike absolute pixel resolution (e.g. 1920×1080 pixels) or relative pixel density (e.g. 401 PPI), but is dependent on the distance between the display and the eye of the person (or lens of the device) viewing the display; moving the eye closer to the display reduces the PPD, and moving away from it increases the PPD in proportion to the distance.

In practice, thus far Apple has converted a device"s display to Retina by doubling the number of pixels in each direction, quadrupling the total resolution. This increase creates a sharper interface at the same physical dimensions. The sole exception to this has been the iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus, which renders its display at triple the number of pixels in each direction, before down-sampling to a 1080p resolution.

The displays are manufactured worldwide by different suppliers. Currently, the iPad"s display comes from Samsung,LG DisplayJapan Display Inc.twisted nematic (TN) liquid-crystal displays (LCDs) to in-plane switching (IPS) LCDs starting with the iPhone 4 models in June 2010.

Apple markets the following devices as having a Retina display, Retina HD display, Liquid Retina display, Liquid Retina XDR display, Super Retina HD display, Super Retina XDR display or Retina 4K/5K/6K display:

Reviews of Apple devices with Retina displays have generally been positive on technical grounds, with comments describing it as a considerable improvement on earlier screens and praising Apple for driving third-party application support for high-resolution displays more effectively than on Windows.T220 and T221 had been sold in the past, they had seen little take-up due to their cost of around $8400.

That much resolution is stunning. To see it on a mainstream device like the iPad—rather than a $13,000 exotic monitor—is truly amazing, and something I"ve been waiting more than a decade to see. It will set a bar for future resolution that every other manufacturer of devices and PCs will have to jump.

Writer John Gruber suggested that the arrival of Retina displays on computers would trigger a need to redesign interfaces and designs for the new displays:

Raymond Soneira, president of DisplayMate Technologies, has challenged Apple"s claim. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of 12 inches (305 mm).Phil Plait notes, however, that, "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4S"s pixels are resolved. The picture will look pixelated. If you have average eyesight [20/20 vision], the picture will look just fine... So in my opinion, what Jobs said was fine. Soneira, while technically correct, was being picky."

Apple fan website CultOfMac hosts an article by John Brownlee"Apple"s Retina Displays are only about 33% of the way there."visual acuity in the population saying "most research suggests that normal vision is actually much better than 20/20" when in truth the majority have worse than 20/20 vision,WHO considers average vision as 20/40.presbyopia

The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the platform however, as all other Symbian-based devices had larger displays with lower resolutions. Some older Symbian smartphones, including the Nokia N80 and N90, featured a 2.1 inch display at 259 ppi, which was one of the sharpest at the time. The first Android smartphones with the same display - Meizu M9 was launched a few months later in beginning of 2011. In October of the same year Galaxy Nexus was announced, which had a display with a better resolution. By 2013 the 300+ ppimark was found on midrange phones such as the Moto G.Samsung Galaxy S4 and HTC One (M8) had 1080p (FHD) screens around 5-inches for a 400+ PPI which surpassed the Retina density on the iPhone 5. The second major redesign of the iPhone, the iPhone 6, has a 1334 × 750 resolution on a 4.7-inch screen, while rivals such as the Samsung Galaxy S6 have a QHD display of 2560 × 1440 resolution, close to four times the number of pixels found in the iPhone 6, giving the S6 a 577 PPI that is almost twice that of the iPhone 6"s 326 PPI.

The larger iPhone 6 Plus features a "Retina HD display", which is a 5.5-inch 1080p screen with 401 PPI. Aside from resolution, all generations of iPhone Retina displays receive high ratings for other aspects such as brightness and color accuracy, compared to those of contemporary smartphones, while some Android devices such as the LG G3 have sacrificed screen quality and battery life for high resolution. Ars Technica suggested the "superfluousness of so many flagship phone features—the move from 720p to 1080p to 1440p and beyond...things are all nice to have, but you’d be hard-pressed to argue that any of them are essential".

Apple is always looking to diversify its suppliers; this helps to improve existing technologies and make them less expensive. This time, TCL’s subsidiary CSOT wants to enter Apple’s LCD supply chain for upcoming Macs and iPads.

The publication says that CSOT is a “fierce competitor” to BOE in the global LCD market, but the company is ahead of CSOT in LCD panels for notebooks, tablets, and monitors as well as with the OLED technology for smartphones.

BOE, as you probably know, has for years been a third supplier of displays for Apple’s older LCD iPhones, but only started making OLED panels for Apple as of the iPhone 12. It was on track to pick up orders for 30-40M iPhones this year. It will also be responsible for around five million units of iPhone 14 OLED panels.

Not only that, but BOE is also supplying LCD panels to Apple for MacBooks and iPads. Analyst firm Omdia says the Chinese company will be the largest supplier of LCD panels for iPad this year.

CSOT also formed a team during the first half of the year to review building an OLED production line aimed at iPhones. CSOT’s expansion plan will, besides BOE, also threaten South Korean display maker LG Display, which leads the supply of LCD panels to Apple for high-end devices.

LG Display is expected to supply 14.8 million LCD panels to Apple for MacBooks this year, according to Omdia, making its share in this specific supply chain 55%. Having another competitor in the supply chain like CSOT could add pressure on LG Display to cut unit prices.

Samsung, a key Apple supplier that manufactures a number of vital components for iPhone, iPad and Mac, on Tuesday said it plans to cease traditional LCD panel production by the end of 2020.

In announcing the development, a spokeswoman for Samsung Display, a subsidiary of Samsung Electronics, said the company will end all LCD manufacturing in South Korea and China by year"s end, reports Reuters. The company in October announced the shutdown of one domestic plant due to weak demand.

Over the next five years, the tech giant will sink money into converting one of its two South Korean LCD plants into a production facility for quantum dot displays.

Used in conventional hardware like LED-backlit LCD panels, quantum dots can be "tuned," or manufactured, to emit very narrow spectrums of light when struck by energy from a common blue backlight, making them a prime candidate for display makers. Further, the construction of a quantum dot LCD panel is similar to that of a traditional LCD screen, with the addition of quantum tubes or films situated next to or on top of backlight LEDs.

Samsung has not decided what to do with the two LCD factories in China that will wind down operations as part of the strategy announced today, the report said.

Samsung has in the past supplied LCD screens for products including iPhone, iPad and Mac, but demand has waned as Apple and other smartphone brands move to OLED. The Korean company fills a bulk of Apple"s OLED orders for flagship iPhone models and Apple Watch, with LG picking up the slack. Chinese firm BOE is reportedly set to enter Apple"s supply chain in 2020 or 2021.

In the immediate future, Apple is rumored to launch at least six devices with mini LED screens, another LCD-based technology that enhances picture quality through highly specific local dimming and better color reproduction.

Samsung"s shift leaves Apple with LG, Japan Display and Sharp as its major LCD screen suppliers, though each are readying their own proprietary OLED products.

It is the iPad that will (hopefully) benefit. It is cheap. It is versatile as it can function either in tablet mode or in laptop mode and so it has a distinct functional advantage over strictly tablet or laptop investments. Plus, since most remote learning tools are web based, a school can assign an iPad to the school"s Apple ID while allowing a student to sign on to their own remote learning ID (say to Google Classroom or Kahn Academy).

The 12.9-inch Liquid Retina XDR display has an IPS LCD panel supporting a resolution of 2732 by 2048 pixels for a total of 5.6 million pixels with 264 pixels per inch. To achieve Extreme Dynamic Range required an entirely new display architecture on iPad Pro. The all new 2D mini-LED backlighting system with individually controlled local dimming zones was the best choice for delivering the extremely high full-screen brightness and contrast ratio, and off-axis color accuracy, that creative professionals depend on for their workflows.

The Liquid Retina XDR display can support up to 1000 nits of full-screen brightness. It can also support up to 1600 nits for highlights in up to 40 percent of the screen area when the rest of that image is black or at brightness up to 600 nits.

Unlike the previous design that takes light emitting from one edge of the display and evenly distributes it across the entire back, the Liquid Retina XDR display uses over 10,000 custom-designed mini-LEDs spread uniformly across the entire back of the display, delivering higher LED density than any other display of its kind. These mini-LEDs are grouped into an array of over 2,500 individually controlled local dimming zones. This delivers incredibly deep blacks right next to bright image areas, achieving a 1,000,000:1 contrast ratio.

The Liquid Retina XDR display improves upon the trade-offs of typical local dimming systems, where the extreme brightness of LEDs might cause a slight blooming effect because the LED zones are larger than the LCD pixel size. This display is designed to deliver crisp front-of-screen performance with its incredibly small custom mini-LED design, industry leading mini-LED density, large number of individually controlled local dimming zones, and custom optical films that shape the light while maintaining image fidelity and extreme brightness and contrast.

Additionally, custom algorithms run on the advanced display engine of the M1 chip, working at the pixel level to control the mini-LED and LCD layers of the display separately, treating them as two distinct displays. These proprietary algorithms coordinate the mini-LED and LCD layers across transitions to deliver the optimal visual experience. Transitional characteristics of local dimming zones, such as a slight blur or color change while scrolling against black backgrounds, are normal behavior.

The Liquid Retina XDR display delivers P3 wide color. The color gamut afforded by the P3 primaries is larger than sRGB, offering richer and more saturated colors, especially with certain reds, yellows, and greens. The result is rich and vibrant color that’s also used in the digital cinema industry. Every Liquid Retina XDR display is also calibrated at the factory for color, brightness, gamma, and white point for a consistent visual experience.

ProMotion technology automatically adjusts the display refresh rate up to 120 Hz (twice the rate of typical LCD displays) to the optimal rate for the content. The result is ultra-smooth scrolling and incredible responsiveness on the display, whether you’re using your finger or Apple Pencil. True Tone technology subtly adjusts the white balance onscreen to match the color temperature of the light around you, so images on the display look as natural as on a printed page. The cover glass on the Liquid Retina XDR display has an on-axis reflection of 1.8 percent due to a custom antireflective coating. As a result, iPad Pro delivers industry-leading reflectivity for a more comfortable viewing experience indoors and out.

LG Display, which posted an operating loss of 361.9 billion won in the first quarter, is enjoying a surge in orders for LCD panels for tablet PCs and laptop monitors in the wake of the new coronavirus outbreak.

Apple has recently asked LG Display to supply LCD panels for the iPad fast. LG Display is expected to start supplying them as early as June by operating the production lines at full throttle.

Earlier, Apple cut orders for the second quarter in anticipation of a significant contraction in the general consumer (B2C) market due to the spread of the COVID-19 virus. However, it started to place additional orders as demand for the iPad surged in Asia due to the spread of remote education and telecommuting in Asia, a region which was relatively successful in coping with COVID-19.

However, Apple"s request was unusual considering the time required to secure raw materials and manufacture products. Normally, orders must be made at least three months in advance. "Since BOE of China and Sharp of Japan are also major suppliers of panels for the Apple iPad, LG Display needs to respond quickly to Apple"s request not to lose the order to its rivals,” an industry insider said.

LG Display has also been selected as a supplier of 6.1-inch panels for Apple"s iPhone 12, which is scheduled to be released this year. The company started supplying OLED panels for the iPhone 11 in 2019. Until recently, Apple had been relying heavily on Samsung Display for OLED panels for the iPhone. LG Display has also secured Huawei as its customers.

Meanwhile, panels for TVs (31 percent) and panels for mobile devices (32 percent) accounted for two-thirds of LG Display"s sales in the first quarter of this year while panels for laptops and tablets took up 12 percent and eight percent, respectively.
