Micro-LED Production - Page 4

During the company's recent conference call, AUO said that the company is undergoing a strategic transformation, focusing on mobility solutions, vertical solutions, and the display segment. The company gave several interesting statements regarding its microLED project and investments.

First of all, the company says that microLED is a priority for the company, and it plans to allocate more resources into its microLED projects. AUO says that its microLED technology is 'gaining traction', and that it is producing microLED displays commercially, but it did not detail more. The company believes it is the leader in microLED development.

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.

MicroLED display developer VueReal announced a strategic partnership with PMOLED producer RiTDisplay display, that will enable device makers to access VueReal's microLED display technologies.

VueReal and RiTDisplay have been collaborating for several years, co-developing automotive displays and lighting solutions. The two companies will now target the consumer market with high-performance and cost-effective displays. The displays will be based on RiT's passive-matrix backplane and VueReal's microLED frontplane solutions.

MicroLED display developer VueReal announced that it plans to double its microLED manufacturing space. VueReal says that its upgraded and expanded facilities serve as both a production center for its customers and also as a blueprint for its partners to build their own fabs.

VueReal is currently offering microLED display production for the automotive market, and it is now also entering the consumer market, targeting wearable devices, TVs, IT applications, and AR products with its MicroSolid Printing platform. 

During AUO's recent investor conference call, the company updated on its microLED project and made some interesting comments. First of all, AUO says that it has started to ship wearable microLED display panels at the end of 2024 (that's in line with AUO's previous announcement).

As far as we know, AUO is working with a Swiss luxury watch producer (like Tag Hauer) that will announce its microLED smartwatch soon. AUO says that it expects to expand its wearable microLED production soon.

US-based signage leader STRATACACHE announced that it has signed a strategic research and IP licensing agreement with US-based Lumiode that will enable STRATACACHE to integrate Lumiode's technology in its upcoming E4 microLED production line in Eugene, Oregon.

Lumiode's technology enables the deposition of an active matrix backplane directly on the LED structure. Lumiode's technology enables the production of both large-area displays and small microdisplays, and it is likely that STRATACACHE is interested in the former. 

Porotech announced a strategic partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corp. (PSMC), to bring Porotech's microLED displays top market. 

The two companies did not disclose much, but Porotech says that this collaboration is an important step forward toward mass production of its microLED microdisplays. 

Finland-based Comptek Solutions develops passivation technology solutions for III-V compound semiconductor materials and devices, based on its novel surface treatment process. Comptek's research leader Marjukka Tuominen will give a talk at the upcoming MicroLED-Connect startup showcase event on February 2024, and Comptek's CEO and co-founder, Vicente Calvo Alonso, was kind enough to send us a short update on the company's technology and status, and his views on the microLED industry and market.

Q: Hello Vicente, thank you for your time. Can you tell us a bit about Comptek, your technology and current status?

Comptek Solutions is an expert in passivation technology solutions for III-V compound semiconductor materials and devices. With our novel surface treatment process, KontroxTM, we are able to control how the oxidation process happens on the surface of the compound materials, and for the first time ever, we can create high quality, crystalline native oxides which are thermodynamically stable and present very low levels of surface state defects.
