imac 27 inch lcd panel factory
I"ve had problems with image retention on my late-2012 27" iMac for a few months now and Apple"s "avoiding image retention" support page is useless for me.
On MacBooks, one can use this Terminal one-liner to check one"s display manufacturer. Is there a similar command for iMacs? I realize that I"ll have to return my iMac sooner or later because this is unacceptable, but I"d still like to know what panel I have before I do it.
Accessibility features help people with disabilities get the most out of their new iMac. With built-in support for vision, hearing, mobility, and learning, you can create and do amazing things.
You can find out what the manufacturer, model number, and type of LCD panel you have in any of your Macs, including the iMac, MacBook Air, MacBook, or any model MacBook Pro by using a fairly complex looking terminal command.
With the first line being the LCD panel model and the second line being the color profile you are using (same as set in your Display preferences). You can then find out what the manufacturer and specs of the display are by googling for the model number, for instance LTN154BT turns up this page indicating it is a Samsung 15″ display running at 1440×900 and capable of displaying a maximum of 262,000 colors.
This is particularly helpful information to know if your MacBook screen has been cracked and you want to do the installation yourself. Official repairs are often very expensive, but with a little patience and the right tools it can be done by anyone. You can typically pick up an LCD panel through Amazon or eBay for rather cheap and the installation takes about 30 minutes if you follow a guide.
It can also be handy to know if you’re just curious which particular panel or screen type is used in your Mac, since Apple often sources different panels from different manufacturers, but otherwise using them in the same Mac models.
The Cupertino company has had a curious and checkered history with displays, launching and then forgetting about a series of options over the years. The Apple Cinema Display and the Thunderbolt Display both lifted their collective heads over the parapets, only to immediately be relegated to obscurity, with extremely slow update cycles, underwhelming specs and extortionate prices. Apple’s Pro Display XDR was launched a couple of years ago, and while it had a hell of a spec, with a 32-inch Retina 6K resolution and ultra-high contrast, it also carried a $4,999 price tag for the standard glass version, and an eye-watering $5,999 for the nano-texture glass version that reduces reflections.
The Apple Studio Display is aimed at a very different audience, and with a $1,599 price tag it isn’t exactly pocket change, but it does something really important. Pair it with the freshly launched Mac Studio, and it finally decouples the screen from the computer. For a company that likes to shout about its environmental chops, it’s about damn time… The number of iMacs I’ve sold because the processor is slow as winter molasses while the screen is still in perfect shape has been a source of infinite frustration. Being able to upgrade just the screen or just the brains of the workstation, while staying within the Apple ecosystem, has been a long time coming.
Oh, yeah, and it has a screen, too. It packs in a 27-inch 5K retina display with 600 nits of brightness and an extra-wide color gamut. Its specs look suspiciously similar to those on the current-gen iMacs. The screen includes an all-aluminum enclosure, and Nano glass, which reduces reflections, is available as an option, as are various stands and mounting options, including a VESA mount option.
According to Reuters, the continued losses suffered by the company is due to "sagging prices" for LCD panels across the board. The company also said its production plans in South Korea and China could be impacted by the emerging trade war between the U.S. and China.
LG Display cited "concern for the global smartphone market," as well as the long-term decline of LG"s LCD panel business. The company has been shifting its emphasis towards OLED panels.
A report earlier this month stated that Apple has ordered between 3 and 4 million OLED panels from LG Display, for use in the 2018 generation of iPhones, with LG expected to become the majority supplier of OLED panels for iPhones for 2019, overtaking its rival Samsung.
There had been reports in April of manufacturing delays on LG"s side affecting Apple"s panel diversifaction plans. As of June, LG was expected to deliver 2 million and 4 million OLED panels to Apple for "a future iPhone," although it"s unclear whether they would be used in this year"s or next year"s models.
LG Display has long been a supplier of 4K and 5K panels for the iMac. LG Display and Samsung both supply screens for the Apple Watch, while LG Display supplies Pad screens as well.
The Studio Display – Apple"s new 27-inch, 5K monitor that was released alongside the new Mac Studio desktop – is one of the most difficult displays I"ve had to review. On the one hand, the price tag is sky-high for a 27-inch 5K panel that "only" promises coverage of the DCI-P3 gamut and is basically incompatible with Widows. On the other hand, it"s extremely color accurate, color uniformity is excellent, and if you doown a Mac, it offers a seamless experience previously only available on the muchmore expensive Pro Display XDR.
I have a hard time praising the Studio Display because it"s not the "baby Pro Display XDR" that I was hoping Apple would release. I"d much rather Apple had budgeted the $1,600 differently by swapping the webcam, speakers, and microphones for a miniLED backlight and a true 10-bit panel that covers 98%+ of bothDCI-P3 and AdobeRGB. That"s what I consider a "Studio" quality display.
All of the variations use the same 5K 27-inch 60Hz IPS LCD panel that promises full coverage of the Display P3 color gamut (DCI-P3 with a D65 white point), for a base price of $1,600. That will get you the standard glass version with either a tilt-adjustable stand or a VESA mount. Spend an extra $400, and you can upgrade to a nicer stand with a height adjustment mechanism similar to the one you found on the Pro Display XDR, albeit without any rotation. And if you want to go all out, you can spend another$300 for the Nano-texture glass.
If you"re using an NVIDIA-powered device, you are able to control basic display parameters like color format and bit depth from the NVIDIA Control Panel, and we can confirm that this works. Changing from 8 bits per channel (bpc) to 10 bpc in the control panel actually made the change at the hardware level. But settings like Brightness, Contrast and Gamma won"t work properly if you adjust them at the level of the GPU.
If you have an NVIDIA-powered PC, you can control a few settings from the NVIDIA Control Panel app. Things like resolution, color format, and bit depth.
The speakers deserve their own paragraph. There are obviously limitations to what you can do with a 5-speaker array build into a 27-inch monitor, but the sound quality from the Studio Display is mind blowing when you compare it to anything other than a dedicated set of desktop computer speakers. They"re extremely loud, with a resonant bass response and crystal clear reproduction that makes the typical 6W or 9W speakers that are built into most monitors sound like hot garbage.
It seems like their goal was to replace the 27-inch iMac with the Mac Studio paired with a Studio Display, and to that end, a great camera, great speakers, and great microphones were a must. I just don"t really care about any of that, and I don"t think most "studio" professionals do either.
The panel at the heart of this display is, spec wise, identical to the panels used in the 5K iMac and the 5K LG UltraFine display that Apple has been selling for several years, but it is not the same panel. Apple confirmed to me that this is a new panel specially designed for this new thin-bezel monitor.
Apple also confirmed this is not a true 10-bit panel. There were several mentions of "over 1 billion colors" during the presentation, but it"s an 8-bit panel with temporal dithering (AKA Frame Rate Control) just like the LCD panels in the 14- and 16-inch MacBook Pros. The only true 10-bit panel is Apple"s lineup is still the Pro Display XDR, and it"s safe to assume that it will stay that way.
Of the 34 test patches, 29 passed recommended tolerance with a Delta E of less than 2, and the remaining 5 were all within nominal tolerance with a maximum Delta E of less than 4. This is exceptional performance that you really only see from high-quality photo- and video-editing displays that put a premium on panel uniformity.
From a performance perspective, this is an excellent panel. My only complaint is the color gamut, which could definitely be wider given the $1,600 price tag. But 99% coverage of DCI-P3 is already great, and when you combine that with the color accuracy and uniformity results above, you"ve got a display that can and should be used for color-critical work.
I see what Apple was trying to do here. It wanted the Studio Display to replace the discontinued 27-inch iMac when paired with a Mac Studio or Mac mini. That"s why it put so much emphasis on features that you don"t typically find in high-end photo- and video-editing displays: like amazing speakers, a built-in webcam, high-quality microphones, and an A13 Bionic to power all of the above. These are all features you"d expect to find in the next-gen iMac, so they"ve packed them inside of the Studio Display instead.
But while these features, when combined with a color-accurate 5K panel, justify the Studio Display"s $1,600 price tag, I would argue that Apple missed the mark by focusing too much on day-to-day usability and too little on the real-world photo-, video-, and graphic design studios that this display is supposedly meant for. Most studios don"t care about webcams or built in speakers, and some even use PCs in addition to (or instead of) Macs.
Earlier today, in their review of the Apple Studio Display, The Verge pointed out that the Studio Display"s webcam image quality left something to be desired. Not properly testing the camera quality was a major oversight on my part, and so I"ve gone back to compare the Studio Display"s built-in webcam against the FaceTime HD camera inside the 14-inch MacBook Pro and a dedicated Logitech Brio 4K webcam.
Compare that to the output from the latest 14-inch MacBook Pro, which (presumably) uses a very similar camera and very similar Apple AI processing to produce a frame with much better contrast and sharpness, and not nearly as much grain:

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 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.
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.
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."
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".
Due to the peculiar diamond Sub-Pixels layout found in the iPhone X, iPhone XS and iPhone XS Max, the actual density of the Red and Blue Sub-Pixels is lower than that of the Green Sub-Pixels, being reportedly 324 Sub-Pixels per inch.
