Tiled microLEDs

Tianma Microelectronics announced that it has developed a new side wiring technology that enables completely seamless tiled microLED displays. The new technology is based on a new process that is much more cost effective compared to other processes, in fact Tianma says it can reduce the cost of side wiring deposition by up to three times.

Tianma shared some details about its first tiled microLED displays. These offer a very small pixel pitch of 0.4 mm, and are based on an LTPS backplane. Tianma also revealed that it is using a laser-bsaed transfer process. The company is now running trial production, and it hopes to improve the yields and production efficiency in 2025, and then move to small batch mass production.

Future Stores has launched its first branch, in London's Oxford Street. The pop-up store retailer offers a next-generation shopping experience, utilizing next-generation technologies.

The shop's inside is almost completely covered by microLED displays. It is actually a single display that includes many surfaces - on the walls, pillars, and ceiling, all controlled by a unified system.

LG Business Solutions, the “Official Display Partner of the Dallas Cowboys”, announced that it has completed the installation of seven MAGNIT microLED displays at the Dallas Cowboy's AT&T Stadium in Arlington, Texas. 

The microLED displays have been installed in the newly renovated Bank of America Founders Club. There's a single 4.88 x 2.44 meters display, two 1.22 x 1.22 meters displays (these are LG's 1.2 mm LSAB012 displays), and two 1.83 x 1.83 meters displays (these are LG's 0.9 mm LSAB009 displays). The premium suites at the stadium also installed LG's OLED TVs. 

LG Electronics announced a strategic plan to focus on its Business Solutions division, with an aim to double its sales to $7.5 billion by 2030. The division is in charge of businss-to-business (B2B) and signage displays, commercial TVs, IT devices such as laptops and monitors, robots and EV chargers.

LG says that for its commercial and signage displays, it will focus on premium fine-pitch LED displays, which include its microLED Magnit models. Indeed LG says that "MAGNIT Micro LED display will be at the forefront of this expansion".  The company reveals that its annual MAGNIT sales grew almost 2X since introducing them in 2020 (though sales are still likely very low). LG plans to launch its next-generaiton AI-powered microLED TVs by the end of 2024. 

In June 2022, Tianma Microelectronics announced plans to establish a 1.1 billion Yuan ($164 million USD) full-process microLED pilot line, in Xiamen. A few days ago, Tianma announced that its production line has commenced trial production. The new production line is co-located with a 8.6-Gen LCD fan at the Tongxiang High-Tech New Town in Xiamen.

Tianma also detailed the first microLED display is produced at the new plant, a 7.5" module aimed towards tiled displays, that offers a brightness of 600 nits and a low 5% reflectance. This is the first time we hear of a tiled microLED display from Tianma, and hopefully Tianma will soon show a large-area TV based on these modules.

Samsung Electronics launched two new MicroLED TVs, in sizes 89-inch and 101-inch. Samsung's "consumer" microLED TV range now includes 89", 101", 110” and 114" sizes.

The price of the 89-inch model is $110,000, and the 101-inch model costs $130,000. Samsung's largest consumer MicroLED TV costs $150,000 at 114-inches.

Innolux showed several new microLED display prototypes at Displayweek 2024, as it focuses on microLEDs as its next-generation display solution.

First, the company showcased a large 106" tiled microLED TV display, build from 96 12.3" modules. The display uses 20x40 um blue microLED chips (with QD color conversion) and an LTPS backplane.

Visionox showed a large 88-inch tiled microLED display, with a pixel pitch of 0.5 mm, based on 25 micron LEDs and an LTPS backplane. The display feature low (<5%) reflectance and a brightness of up to 1,200 nits.

Vistar also showed a 14.5" panel, a single module that is used to build the 88-inch TV. Visionox says that it developed a dedicated microLED driver IC, that enables 10-bit color depth and "True Color" presentation. Vistar says that it reaches production yields of 99.995% in its mass transfer process, and a repair process that enables perfect displays.

At Displayweek 2024, TCL CSoT demonstrated its impressive 163-inch 4K (0.9375 mm pitch) tiled MicroLED display on show, that offered very high brightness (10,000 nits).

TCL says that the display has a 'nanosecond' response time, and its lifetime rating is over 100,000 hours. This is TCL's X11H Max commercial MicroLED TV, priced at $110,000.

AUO had an impressive booth at Displayweek, showing some of its latest microLED prototypes. It is clear that the company is highly focused on microLED technology as its next-gen display strategy.

First up, with a 31" large area single-panel microLED, which AUO says is the world's largest. The display is produced on a single glass LTPS backplane, and offers 120Hz and a brightness of 500 nits. AUO calls this a Large Size A.R.T. MicroLED display.
