ipad lcd display manufacturer

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.

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).

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.

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".

The M1 chipset. Loads of RAM. 5G. Thunderbolt support. All of these help make Apple’s new, 12.9-inch iPad Pro an almost startlingly capable tablet, one that seems well-equipped to compete against more traditional laptops. (Well, apart from iPadOS’s limitations, anyway.) But if there"s one area where the iPad Pro clearly outshines the rest of Apple’s portable computers, it"s the tablet"s brand new screen.

To learn a little more about what it took to build the Liquid Retina XDR screen, Engadget spoke to Vincent Gu, a senior engineering manager for Apple displays, and iPad marketing spokesperson Scott Broderick, who was quick to claim it is "the absolute best display we could put in the 12.9-inch iPad Pro,” Broderick said.

While some could justifiably argue that an OLED display like those seen in Apple’s iPhone 12 series might be even more impressive, Broderick has a point: this is one damned-good-looking screen.

But first, we should break down that name. As I mentioned in our iPad Pro review, the “liquid” bit refers to the fact that this is actually an LCD screen, which — unlike the OLED displays found in newer iPhones and other high-end mobile devices — relies on a bevy of small backlights to actually make the screen visible. “Retina” is a bit of classic Apple marketing fluff, which the company has used to refer to its mobile displays since the days of the iPhone 4. And the “XDR” part isn"t just meant to evoke images of Apple"s expensive, high-end monitors — it refers to the display"s "extreme" dynamic range.

Ultimately, what makes this display so appealing isn’t its size — it’s the same 12.9 inches as before — or the fact that it refreshes at 120Hz. No, it’s all because of a component you can’t even directly see: a new backlighting system composed of more than 10,000 super-small LEDs, divided up into 2,596 local dimming zones. (In case you were keeping count, Apple’s $5,000, 6K Pro Display XDR monitor only has 576 dimming zones.)

The idea is pretty simple: by making those light sources smaller, Apple could fit more of them behind the rest of the LCD panel"s many layers, allowing for more precise control over what parts of the screen are lit up in any given moment. It’s a pretty standard concept in the TV world, with TCL, Samsung, and LG each with their own confusingly branded version. For what it’s worth, though, Apple insists that its own mini-LED backlighting system was designed completely in-house.

“The mini LEDs we put into Liquid Retina XDR is a truly custom-designed, Apple-proprietary technology,” said Gu, who noted that they were more than a hundred times smaller than those used in last year’s iPad Pro. To no one’s surprise, carefully arranging those thousands of LEDs was a crucial hurdle, one Apple only managed to clear thanks to engineers who custom-designed manufacturing equipment and created their own special solder.

“We had to deliver specific equipment to be able to put these over 10,000 mini LEDs into place with such precision that didn’t exist prior to us,” said iPad spokesperson Broderick. (That said, Apple declined to tell us exactly how small each individual mini LED measures, or how long it takes to produce a single Liquid Retina XDR screen.)

Beyond the lighting system, Gu also said the switch to mini LEDs required Apple to re-engineer core components of its display stack, including the optical films and diffusers that help control the flow of light and distribute it evenly across the entire panel. And then, Apple’s design and manufacturing engineers had to take that new, physically larger screen package and bake it into a kind of device that has been synonymous with portability. In other words, the whole process was... sort of a pain.

It"s a good thing for the company"s engineers, then, that the mini-LED screen is said to remain a key part of the iPad Pro experience for a while. But that"s not to say other changes aren"t in the offing. Apple analyst Ming-Chi Kuo suggested in a recent note that Apple could shift to using OLED displays — which are known for their deep blacks and extremely vivid colors — in the iPad Air as early as next year. (For what it"s worth, Broderick and Gu wouldn"t confirm whether Apple had contemplated using OLED panels in the iPad Pro)

The reason many phones use ipad screen rather than LED or AMOLED screens is because of their relatively cheaper cost. Additionally, smartphone lcd screens also use less power than LED or AMOLED screens and therefore help conserve battery power. With today"s powerful apps, this can be a real advantage for those who do not like to or do not have the ability to charge their phone frequently.

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.

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.

Nowadays, LCD panels for smartphone displays are taking the back seat while tech companies move towards OLED screens, including Apple. Samsung Display, one of Apple’s suppliers for iPhone, iPad and Apple Watch displays, announced today that it is going to end LCD production in its China-based and South Korean factories by the end of 2020.

Reuters now reports that Samsung is moving on with its factories, but will still supply LCD display orders until the end of the year. The company has two LCD production lines in South Korea and two LCD-dedicated factories in China.

The production of LCD displays by Samsung has already been in decline since last year, as demand for LCD screens is continuously decreasing. In October, Samsung closed one of its LCD production lines in South Korea. Additionally, the company stated that it will invest around $10.72 billion in research and improvements for their production lines of quantum dot screens.

If you haven"t yet laid eyes on the new iPad"s screen, you must. "Sharp" doesn"t begin to describe Apple"s upgrade in display quality. But here"s the kicker: Samsung, a company firmly aligned with Android and one of Apple"s largest competitors in the mobile space, is manufacturing the new iPad"s flagship feature.

So, naturally, questions arise: Why are we seeing Retina displays in iPads but not in Samsung"s own Galaxy-branded tablets? Why would Samsung allow itself to be trumped by a mere customer?

Example: While Samsung pumps out tens of thousands of high-end LCD panels for Apple, the two companies remain embroiled in longstanding intellectual property litigation, with Apple accusing Samsung of blatantly ripping off the iOS user interface, as well as Apple"s iconic product designs.

Samsung isn"t just "Samsung," though. It"s a massive, multi-national conglomerate made up of more than 30 independent businesses, covering areas as disparate as life insurance and petrochemical engineering. One such free agent is Samsung Mobile Display. Founded in 2009, this company takes the years of R&D done by Samsung Electronics and Samsung SDI in AMOLED technology, and uses it to tuck nicely into products such as televisions, tablets and mobile phones.

So while Samsung Electronics Company LTD gets its pants sued off, Samsung Mobile Display wheels and deals with Apple at the very same time. And, of course, while all this is happening, both companies compete fiercely to sell mobile phones and tablets as quickly as possible.

Samsung isn"t the only company that manufactures displays for direct hardware competitors. LG and Sony -- both notable players in the Android phone and tablet space -- do it too. To put it simply: It"s complicated.

As it stands, Samsung champions a display technology for its own mobile products that"s currently of no appeal to Apple. Dubbed AMOLED (shorthand for active-matrix organic light-emitting diode), Samsung has deployed this display tech in millions of mobile phones -- most notably, the Galaxy SII, the company"s flagship Android device of 2011. The Galaxy Tab 7.7 also touts a Super AMOLED display as one of its most noteworthy features. (The "Super" variety of AMOLED integrates touch sensors directly in the surface glass of the screen, increasing brightness and reducing power consumption.)

In a sense, Samsung has a notable edge over competitors in the display space. Currently, Samsung Mobile Display is still the only manufacturer that can mass-produce Super AMOLED displays, says NPD DisplaySearch analyst Paul Semenza. And the company is using its advantage by pushing it out to Samsung-branded phones. "The Galaxy S phones have been quite successful by highlighting the AMOLED display," Semenza says.
