As smartphone camera resolutions continue to improve, lenses inevitably become thicker, impacting the weight of the devices. Market rumors suggest that Apple has been researching metalens technology over the past few years, with plans to initially use it to replace the plastic lenses in the iPad's Face ID system. Metalens technology could debut in the Face ID of the iPhone 16 Pro and flagship models as early as 2024.

As LED demand recovers, many companies have experienced operational improvements in the first half of 2024, particularly in the invisible light and automotive markets, which have become key drivers of sales growth.

An anonymous reader quotes a report from Ars Technica, written by Andrew Cunningham: Back in 2013, Nvidia introduced a new technology called G-Sync to eliminate screen tearing and stuttering effects and reduce input lag when playing PC games. The company accomplished this by tying your display's refresh rate to the actual frame rate of the game you were playing, and similar variable refresh-rate (VRR) technology has become a mainstay even in budget monitors and TVs today. The issue for Nvidia is that G-Sync isn't what has been driving most of that adoption. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens. Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM. These new MediaTek scalers will support all the same features that current dedicated G-Sync modules do. Nvidia says that three G-Sync monitors with MediaTek scaler chips inside will launch "later this year": the Asus ROG Swift PG27AQNR, the Acer Predator XB273U F5, and the AOC AGON PRO AG276QSG2. These are all 27-inch 1440p displays with maximum refresh rates of 360 Hz.

Although Innolux just turned around in the second quarter of 2024, James Yang, President of the company, recently indicated uncertainties when looking ahead to the third quarter. Demand is expected to decrease, and Innolux's utilization rate will be reduced by about 5%. This slowdown in demand is anticipated to continue until the first quarter of 2025, with hopes for a surge in AI-related product replacements in 2025, leading to better notebook demand.

Apple's new iPhone is slated to launch in the second half of 2024, sparking intense competition between the two major South Korean panel manufacturers for the iPhone's OLED market. Reports indicate that Samsung Display (SDC) and LG Display (LGD) are aggressively vying for OLED orders in the iPhone 16 series' two high-end models.

LG Display (LGD) is expected to become the second supplier of OLED panels for Apple's iPhone SE4, slated for release in the first half of 2025. Samsung Display (SDC) will focus primarily on the high-end iPhone 16 series.

Taiwanese panel giant AUO is undergoing a significant transformation to diversify its business and reduce reliance on the cyclical display panel market. The company is focusing on three core operating structures: smart mobility solutions, vertical solutions, and display technology.

A transparent television might seem like magic, but both LG and Samsung demonstrated such displays this past January in Las Vegas at CES 2024. And those large transparent TVs, which attracted countless spectators peeking through video images dancing on their screens, were showstoppers.

Although they are indeed impressive, transparent TVs are not likely to appear—or disappear—in your living room any time soon. Samsung and LG have taken two very different approaches to achieve a similar end—LG is betting on OLED displays, while Samsung is pursuing microLED screens—and neither technology is quite ready for prime time. Understanding the hurdles that still need to be overcome, though, requires a deeper dive into each of these display technologies.

How does LG’s see-through OLED work?

OLED stands for organic light-emitting diode, and that pretty much describes how it works. OLED materials are carbon-based compounds that emit light when energized with an electrical current. Different compounds produce different colors, which can be combined to create full-color images.

To construct a display from these materials, manufacturers deposit them as thin films on some sort of substrate. The most common approach arranges red-, green-, and blue-emitting (RGB) materials in patterns to create a dense array of full-color pixels. A display with what is known as 4K resolution contains a matrix of 3,840 by 2,160 pixels—8.3 million pixels in all, formed from nearly 25 million red, green, and blue subpixels.

The timing and amount of electrical current sent to each subpixel determines how much light it emits. So by controlling these currents properly, you can create the desired image on the screen. To accomplish this, each subpixel must be electrically connected to two or more transistors, which act as switches. Traditional wires wouldn’t do for this, though: They’d block the light. You need to use transparent (or largely transparent) conductive traces.

A display has thousands of such traces arranged in a series of rows and columns to provide the necessary electrical connections to each subpixel. The transistor switches are also fabricated on the same substrate. That all adds up to a lot of materials that must be part of each display. And those materials must be carefully chosen for the OLED display to appear transparent.

The conductive traces are the easy part. The display industry has long used indium tin oxide as a thin-film conductor. A typical layer of this material is only 135 nanometers thick but allows about 80 percent of the light impinging on it to pass through.

The transistors are more of a problem, because the materials used to fabricate them are inherently opaque. The solution is to make the transistors as small as you can, so that they block the least amount of light. The amorphous silicon layer used for transistors in most LCD displays is inexpensive, but its low electron mobility means that transistors composed of this material can only be made so small. This silicon layer can be annealed with lasers to create low-temperature polysilicon, a crystallized form of silicon, which improves electron mobility, reducing the size of each transistor. But this process works only for small sheets of glass substrate.

Faced with this challenge, designers of transparent OLED displays have turned to indium gallium zinc oxide (IGZO). This material has high enough electron mobility to allow for smaller transistors than is possible with amorphous silicon, meaning that IGZO transistors block less light.

These tactics help solve the transparency problem, but OLEDs have some other challenges. For one, exposure to oxygen or water vapor destroys the light-emissive materials. So these displays need an encapsulating layer, something to cover their surfaces and edges. Because this layer creates a visible gap when two panels are placed edge to edge, you can’t tile a set of smaller displays to create a larger one. If you want a big OLED display, you need to fabricate a single large panel.

The result of even the best engineering here is a “transparent” display that still blocks some light. You won’t mistake LG’s transparent TV for window glass: People and objects behind the screen appear noticeably darker than when viewed directly. According to one informed observer, the LG prototype appears to have 45 percent transparency.

How does Samsung’s magical MicroLED work?

For its transparent displays, Samsung is using inorganic LEDs. These devices, which are very efficient at converting electricity into light, are commonplace today: in household lightbulbs, in automobile headlights and taillights, and in electronic gear, where they often show that the unit is turned on.

In LED displays, each pixel contains three LEDs, one red, one green, and one blue. This works great for the giant digital displays used in highway billboards or in sports-stadium jumbotrons, whose images are meant to be viewed from a good distance. But up close, these LED pixel arrays are noticeable.

TV displays, on the other hand, are meant to be viewed from modest distances and thus require far smaller LEDs than the chips used in, say, power-indicator lights. Two years ago, these “microLED” displays used chips that were just 30 by 50 micrometers. (A typical sheet of paper is 100 micrometers thick.) Today, such displays use chips less than half that size: 12 by 27 micrometers.

While transparent displays are stunning, they might not be practical for home use as televisions. Expect to see them adopted first as signage in retail settings. AUO

These tiny LED chips block very little light, making the display more transparent. The Taiwanese display maker AUO recently demonstrated a microLED display with more than 60 percent transparency.

Oxygen and moisture don’t affect microLEDs, so they don’t need to be encapsulated. This makes it possible to tile smaller panels to create a seamless larger display. And the silicon coating on such small panels can be annealed to create polysilicon, which performs better than IGZO, so the transistors can be even smaller and block less light.

But the microLED approach has its own problems. Indeed, the technology is still in its infancy, with costing a great deal to manufacture and requiring some contortions to get uniform brightness and color across the entire display.

For example, individual OLED materials emit a well-defined color, but that’s not the case for LEDs. Minute variations in the physical characteristics of an LED chip can alter the wavelength of light it emits by a measurable—and noticeable—amount. Manufacturers have typically addressed this challenge by using a binning process: They test thousands of chips and then group them into bins of similar wavelengths, discarding those that don’t fit the desired ranges. This explains in part why those large digital LED screens are so expensive: Many LEDs created for their construction must be discarded.

But binning doesn’t really work when dealing with microLEDs. The tiny chips are difficult to test and are so expensive that costs would be astronomical if too many had to be rejected.

Though you can see through today’s transparent displays, they do block a noticeable amount of light, making the background darker than when viewed directly. Tekla S. Perry

Instead, manufacturers test microLED displays for uniformity after they’re assembled, then calibrate them to adjust the current applied to each subpixel so that color and brightness are uniform across the display. This calibration process, which involves scanning an image on the panel and then reprogramming the control circuitry, can sometimes require thousands of iterations.

Then there’s the problem of assembling the panels. Remember those 25 million microLED chips that make up a 4K display? Each must be positioned precisely, and each must be connected to the correct electrical contacts.

The LED chips are initially fabricated on sapphire wafers, each of which contains chips of only one color. These chips must be transferred from the wafer to a carrier to hold them temporarily before applying them to the panel backplane. The Taiwanese microLED company PlayNitride has developed a process for creating large tiles with chips spaced less than 2 micrometers apart. Its process for positioning these tiny chips has better than 99.9 percent yields. But even at a 99.9 percent yield, you can expect about 25,000 defective subpixels in a 4K display. They might be positioned incorrectly so that no electrical contact is made, or the wrong color chip is placed in the pattern, or a subpixel chip might be defective. While correcting these defects is sometimes possible, doing so just adds to the already high cost.

Could MicroLEDs still be the future of flat-panel displays? “Every display analyst I know believes that microLEDs should be the ‘next big thing’ because of their brightness, efficiency, color, viewing angles, response times, and lifetime, “ says Bob Raikes, editor of the 8K Monitor newsletter. “However, the practical hurdles of bringing them to market remain huge. That Apple, which has the deepest pockets of all, has abandoned microLEDs, at least for now, and after billions of dollars in investment, suggests that mass production for consumer markets is still a long way off.”

At this juncture, even though microLED technology offers some clear advantages, OLED is more cost-effective and holds the early lead for practical applications of transparent displays.

But what is a transparent display good for?

Samsung and LG aren’t the only companies to have demonstrated transparent panels recently.

AUO’s 60-inch transparent display, made of tiled panels, won the People’s Choice Award for Best MicroLED-Based Technology at the Society for Information Display’s Display Week, held in May in San Jose, Calif. And the Chinese company BOE Technology Group demonstrated a 49-inch transparent OLED display at CES 2024.

These transparent displays all have one feature in common: They will be insanely expensive. Only LG’s transparent OLED display has been announced as a commercial product. It’s without a price or a ship date at this point, but it’s not hard to guess how costly it will be, given that nontransparent versions are expensive enough. For example, LG prices its top-end 77-inch OLED TV at US $4,500.

Displays using both microLED technology [above] and OLED technology have some components in each pixel that block light coming from the background. These include the red, green, and blue emissive materials along with the transistors required to switch them on and off. Smaller components mean that you can have a larger transmissive space that will provide greater transparency. Illustration: Mark Montgomery; Source: Samsung

Thanks to seamless tiling, transparent microLED displays can be larger than their OLED counterparts. But their production costs are larger as well. Much larger. And that is reflected in prices. For example, Samsung’s nontransparent 114-inch microLED TV sells for $150,000. We can reasonably expect transparent models to cost even more.

Seeing these prices, you really have to ask: What are the practical applications of transparent displays?

Don’t expect these displays to show up in many living rooms as televisions. And high price is not the only reason. After all, who wants to see their bookshelves showing through in the background while they’re watching Dune? That’s why the transparent OLED TV LG demonstrated at CES 2024 included a “contrast layer”—basically, a black cloth—that unrolls and covers the back of the display on demand.

Transparent displays could have a place on the desktop—not so you can see through them, but so that a camera can sit behind the display, capturing your image while you’re looking directly at the screen. This would help you maintain eye contact during a Zoom call. One company—Veeo—demonstrated a prototype of such a product at CES 2024, and it plans to release a 30-inch model for about $3,000 and a 55-inch model for about $8,500 later this year. Veeo’s products use LG’s transparent OLED technology.

Transparent screens are already showing up as signage and other public-information displays. LG has installed transparent 55-inch OLED panels in the windows of Seoul’s new high-speed underground rail cars, which are part of a system known as the Great Train eXpress. Riders can browse maps and other information on these displays, which can be made clear when needed for passengers to see what’s outside.

LG transparent panels have also been featured in an E35e excavator prototype by Doosan Bobcat. This touchscreen display can act as the operator’s front or side window, showing important machine data or displaying real-time images from cameras mounted on the vehicle. Such transparent displays can serve a similar function as the head-up displays in some aircraft windshields.

And so, while the large transparent displays are striking, you’ll be more likely to see them initially as displays for machinery operators, public entertainment, retail signage, and even car windshields. The early adopters might cover the costs of developing mass-production processes, which in turn could drive prices down. But even if costs eventually reach reasonable levels, whether the average consumer really want a transparent TV in their home is something that remains to be seen—unlike the device itself, whose whole point is not to be.

BOE Technology, the largest Chinese display panel manufacturer, is reportedly placing equipment orders for its 8.6-generation (8.6G) OLED panel plant under construction in China. Many South Korean equipment makers, including Sunic System, Avaco, Shinsung E&G, and DMS, are expected to benefit as potential suppliers.

The recent reports of Apple's delayed launch of the next-generation Vision Pro cast a shadow over the market outlook for OLED on Silicon (OLEDoS) technologies.

Samsung Display (SDC) has unveiled its outlook for the LED on Silicon (LEDoS) technology for Augmented Reality (AR) device displays, expecting that LEDoS technology will evolve from the "Blue + Quantum Dot (QD)" method to the "RGB 3-panel" and "Monolithic 1-panel" methods.

Due to the continuous expansion of production capacity in China, the polarizer industry is facing a problem of oversupply that exceeds even the demand for panel productions.

AUO is transforming its business structure, aiming to lower regular display panel sales to below 70% of overall company revenue in 2025, according to company chairman Paul Peng.

The world's first 10th-generation LCD panel factory, located in Japan's Sakai and operated by Sharp subsidiary Sakai Display Products (SDP), is set to cease production by September 2024. The impending closure has ignited industry concerns regarding how major customers, including Shenzhen MTC, Samsung Electronics, and LG Electronics, will reassess their supply partnerships for transferring orders.

TCL CSOT recently showcased its 7.85-inch tri-fold flexible OLED and other technologies at the Display Week 2024 event organized by the Society of Information Display (SID) in San Jose, California. TCL CSOT exhibited over 40 different panel products, spanning smartphones, tablets, notebooks, automotive displays, TVs, and medical devices. Among these, their printed OLED and flexible OLED technologies received the most attention.

VESA this morning is taking the wraps off of the next iteration of its DisplayHDR monitor certification standard, DisplayHDR 1.2. Designed to raise the bar on display quality, the updated DisplayHDR conformance test suite imposes new luminance, color gamut, and color accuracy requirements that extend across the entire spectrum of DisplayHDR tiers – including the entry-level DisplayHDR 400 tier. With vendors able to begin certifying displays for the new standard immediately, the display technology group is aiming to address the advancements in the display technology market over the last several years, while enticing display manufacturers to make use of them to deliver better desktop and laptop displays than before.

Altogether, the DisplayHDR 1.2 is easily the biggest update to the standard since it launched in 2017, and in many respects the first significant overhaul to the standard since that time as well. DisplayHDR 1.2 doesn’t add any new tiers to the standard (e.g. 1400), instead it’s all about increasing and/or tightening the specifications at each of its tier levels. In short, the VESA is raising the bar for displays to reach DisplayHDR compliance, requiring a higher level of performance and testing for more corner cases that trip up lesser displays.

All of these changes are coming, in turn, after over half a decade of technology improvements in the display space. Whereas even the original DisplayHDR 400 requirements represented a modestly premium display in 2017, nowadays even sub-$200 displays can hit those relatively loose requirements as panels and backlighting solutions have improved. And even at the high-end of things, full array local dimming (FALD) displays have gone from hundreds of zones to thousands. All of which has finally pushed VESA’s member companies into allowing higher standards going forward.

Market research firm DSCC recently stated that for Apple's OLED iPad launched in 2024, LG Display (LGD) is expected to account for over 65% of the panel shipments, ahead of Samsung Display (SDC). Observers in the South Korean industry have raised concerns about Apple issuing rather harsh requirements, suspecting that Apple may be attempting to shift the "responsibility" of weak sales and shipments onto the South Korean panel manufacturers

Apple reportedly has struck an agreement with South Korean panel supplier Samsung Display (SDC) for the development of foldable devices, according to speculation from the supply chain, according to industry sources.

Apple reportedly has struck an agreement with South Korean panel supplier Samsung Display (SDC) for the development of foldable devices, according to speculation from the supply chain, according to industry sources.

With sluggish iPhone sales and intense competition from Chinese panel manufacturers, Samsung Display (SDC)'s operating profit in the first quarter of 2024 saw a 56% year-on-year decrease. How SDC will respond to this has received a lot of attention.

Micro LED applications are expected to multiply in the coming years, especially in the automotive sector. Li Yun-Li, CEO of micro LED supplier PlayNitride, said customers will likely put the company's product into concept vehicles in 2025 and enter the design phase of volume-production cars in 2027. The adoption of micro LED solutions in EVs could progress faster than expected.

Taiwan's major panel specialist Innolux is poised to wow the audiences at the upcoming Touch Taiwan 2024 by showcasing the industry's first color conversion MicroLED display technology alongside other pioneering MicroLED innovations and applications.

After securing a 27-inch OLED display sale to Hyundai Motor Group's Genesis, LG Display (LGD) also reportedly received a large-sized LCD order from a foreign luxury car brand. This LCD order represents the longest size among LGD's automotive displays and is currently in preparation, with a target to officially begin mass production in the first quarter of 2026.

After fully embracing AI with the recent launch of the Galaxy S24 series flagship smartphones, Samsung Electronics unveiled its new lineup of Neo QLED, OLED, and Lifestyle series displays in Taiwan on April 17, where it also emphasized the advantages of AI in improving display performance and color rendering. By offering a more complete product line, Samsung hopes to take a leading sales position in the high-end display market and maintain double-digit growth for large-size TV sales in Taiwan in 2024.

Display leader BOE Technology began constructing the second plant of its Vietnam facility in addition to announcing the Smart GOAL strategy.

Apple is set to launch a new generation of the iPad Pro as early as March 2024. The total supply volume of OLED panels is estimated to be 8.5 million units, and it will be fully supplied by South Korea's Samsung Display (SDC) and LG Display (LGD). However, the absence of Chinese manufacturers like BOE has certainly garnered some attention.

E-paper solutions provider E Ink Holdings (EIH) anticipates revenue will be at its lowest for 2024 in the first quarter of 2024 before increasing and sustaining growth through the final quarter of 2024.

The demand for LED products is gradually warming up following a period of inventory adjustments in the market. While LED companies experienced a general decline in revenue for February 2024, they have been bolstered by steady demand in consumer and automotive applications. Ennostar and Everlight Electronics reported a double-digit year-on-year growth in cumulative revenue for January and February, with performance in the first quarter of this year poised to see year-on-year growth as well.

As global geopolitical tension, economic instability, and persistent inflation affected the recovery of consumer products, Coretronic's shipments and revenue declined in 2023. However, the commencement of mass production at its second Vietnamese factory in February is expected to boost the business this year, and more significant growth is expected in 2025. Overall, since some of Coretronic's projects would only officially commence in the fourth quarter of this year, a stronger growth momentum is anticipated in 2025.

Recent reports speculated that Apple might introduce its latest budget model, the iPhone SE 4, in 2025. It'll be equipped with the iPhone 14 OLED panel. Because the iPhone 14 OLED is considered a more mature product, Chinese manufacturers like BOE are expected to actively compete with Samsung Display (SDC) for the supply opportunity.

AUO is accelerating its efforts in MicroLED technology to secure a leading position in the next-generation display market. The company anticipates its automotive products to enter mass production between 2026 -2027. Industry sources reveal that AUO's clients in the automotive industry include major automotive manufacturers such as BMW, Audi, and Mercedes-Benz.

Taiwan-based E Ink Holdings (EIH), a provider of e-paper solutions, has launched a recruitment initiative to hire an additional 150 individuals for capacity expansion over the next 2-3 years. This is part of a broader expansion plan that includes increasing production lines and office buildings.

Taiwan-based Innolux, a technology partner with India-based Vedanta on TFT-LCD panels, said its collaboration with Vedanta will begin mass production of display panels in two years after approval and is likely to reach break-even two years after operation.
