TCL shows a tiled 163" microLED display prototype
TCL has demonstrated a 163" microLED TV display prototype. This seems to be the same display showed at IFA 2023 last year.
We do not have any more technical details. In May 2023, TCL unveiled a small tiled display (18.8"), this could be based on the same tiles. The 2023 display featured a pixel-pitch of 0.43 mm, an IGZO backplane and a peak brightness of 1,200 nits. CSoT says that the LED chips have an area of 400 squm, which means chip size of about 20 microns.
Konka shows a massive 310" 4K-Plus microLED display
At CES 2024, Konka is demonstrating a massive 310" microLED display. The display offers 4K-Plus resolution (Konka did not detail the exact resolution), low reflectivity (<5%), 800 nits of brightness, high refresh rate (not detailed) and a large color gamut (85% BT.2020).
Konka says that this display uses the company's self developed and fully proprietary microLED chips. Konka produces its microLED chips using Aixtron's MOCVD systems.
AUO to demonstrate a 108-inch microLED TV display in 2024
AUO announced that it will demonstrate a 108-inch residential microLED TV during ISE Europe 2024 (January 30, 2024). As far as we know, this is the first time that AUO shows a large-area microLED display. The screen is most likely a tiled microLED display.
Last month AUO announced its plans to invest further in its microLED technologies, and re-iterated its plans to mass produce microLED smartwatch displays by the end of 2023 - and also to introduce automotive and TV displays. You can read more about AUO's microLED wearable display project here.
DSCC: the microLED display market to reach $1.4 billion by 2028, led by TV, wearables, automotive and AR displays
DSCC estimates that the microLED display market will reach $1.4 billion by 2028, led by TVs and wearables. Other applications will include AR glasses and automotive displays (these do not appear in the graph below).
DSCC believes that MicroLED displays will offer superior performance, but its high price will keep it from being a mainstream technology in the near future. The first microLED smartwatch will launch in 2024, but it will target the high-end of the market and volumes will remain low.
Yole sees significant microLED production in 2-3 years, with broader adoption in 5-10 years
Yole Intelligence has published its latest microLED market report, in which it sees commercial microLED production starting in 2-3 years, following several delays. In 5-10 years, adoption will increase.
In its base scenario, Yole sees microLED panel sales reaching $1.5 billion in 2029 and $2.2 billion in 2030, with almost 90% coming from wearables and AR/VR/MR microdisplays. The rest of the panels will be used in TV applications. If you want to hear more about Yole's microLED market insights, you are welcome to join the MicroLED-Connect online event later this month.
How seamless are microLED tiled TV displays?
Samsung, Sony, LG and others are producing commercial microLED panels, mostly for ultra-premium, signage and commercial applications. The ultra-large size displays are made from small microLED modules, seamlessly tiled together.
MicroLED technology makes it possible to connect two tiles in a way that retains exactly the same pixel pitch even at the tile connection (this is something that is challenging to do with OLED or LCD displays). When the displays are active, it is indeed very difficult to spot the seam. When the display is completely black however, this is not the case, and the seams are visible, and the different modules (which are never 100% aligned) reflect light a bit differently which creates a mosaic-like image.
AUO reiterates its plans to mass produce microLED smartwatch displays by the end of 2023, to expand microLEDs to TVs and Automotives
During the company's latest conference call, AU Optronics made some interesting remarks on its microLED project. First of all, the company intends to continue investing in micro-LED technologies going forward. That's not a surprise. Second, the company re-iterated its plans to mass produce microLED smartwatch displays by the end of 2023.
AUO also says it plans to apply microLED displays to an "increasing number of high end TV and automotive display products". AUO will increase its microLED display range and make it commercially available to more products and applications. As far as we know, this is the first time that AUO discusses microLED TVs.
North Carolina State University installs a 6 x 2.5 meters Sony microLED display at one of its libraries
North Carolina State University’s James B. Hunt Jr. Library installed a large curved Sony Crystal LED microLED display, to replace several video walls that were previously used.
The Sony microLED display was installed in a space known as the iPearl Immersion Theater. The display has a resolution of 4000 x 1620, and it’s approximately 6 x 2.5 meter in size. The display works as a digital exhibit space for student, faculty and community projects, so viewers will see student and faculty work, community project results, and special events information.
Just Video Wall launches a microLED TV design tool to assist potential customers
Just Video Wall, a system integrator that focuses entirely on microLED displays, has launched a MicroLED TV design tool that aims to make the MicroLED quoting process easier.
The company says that their patent-pending design tool enables custom display professionals to enter the MicroLED space by starting with the project parameters, not the product lines or individual specs. The system presents the best range of possible options, based on a questionnaire derived from years of experience in installation and application.
Visionox shows a 58-inch tiled microLED display prototype
Visionox demonstrated a new microLED display prototype, a 58-inch tiled display, made from a matrix of 16 modules (each 14.5" in size). The display offers a 10-bit color depth, 240Hz refresh rate, and an ultra-high contrast.
Visionox says that the new display uses 25 um microLED chips, and utilizes China's first dedicated microLED driver IC and a TFT backplane (likely LTPS). From the image we have, it seems as if there are much more than 16 modules, and the seams are quite visible, this seems to be an early-stage display prototype.
