An overview of the latest microLED TV market news

It is quite challenging to produce microLED TVs, and while display companies all over the world are investing billions into R&D, and are developing new process and production technologies, we're still quite far from the emergence of mass production of microLED displays.

Konka APHAEA microLED TV launch

As we discussed earlier this month, it happens that even though the industry is still at an early stage, microLEDs are finding early market niches, mostly in AR/VR microdisplays and large-format TVs. Indeed the microLED TV market is promising and companies such as Sony, Samsung, LG, Konka and others already offer large-area tiled microLED TVs for the premium-consumer market. Here are some of the latest microLED TV updates that we published in recent months:

Q&A with the CEO of MicroLED driver and backplane developer SAPIEN

SAPIEN Semiconductors, based in Korea, is a fabless design company that provides innovative PWM CMOS backplane and µ-driver ICs for Micro-LED displays. The company utilizes its own patented technologies to achieve lower power consumption, lower leakage, better repairability and improved testability.

In the following interview, we discuss the company’s technology and business with its CEO, Myunghee Lee.

Q: Hello Mr. Lee, thank you for your time. Can you give us a short introduction to SAPIEN and your microLED technologies?

SAPIEN specializes in developing CMOS Backplane SoCs (System-on-Chip) for Micro-LED display applications. SAPIEN was founded in 2017 by industry veterans who have over 230 years of combined design experience in Display Driver ICs (DDI).

Why microLED displays may take longer than expected to reach the market

MicroLED displays show great promise, as the technology enables emissive displays that can offer performance on par with OLED displays and higher brightness and efficiency. In addition, these displays can offer higher lifetimes and less burn-in.

However, the production of microLED displays is still very challenging - with many issues that are yet to be resolved - around the LED epiwafer growth, the transfer process, RGB backplanes, inspection and repair, and more. Even after billions of dollars that have gone into microLED display technologies R&D, display makers are not ready for actual mass production.

We talk lasers in the microLED industry with Bolite Optoelectronics' CEO

The founder and General Manager of Bolite Optoelectronics, Dr. Bowen Cheng, was invited to present at the recent Touch Taiwan 2021 Conference in April. The title of his talk was “Laser Processing Applications for the Manufacturing of Mini and MicroLED Displays.” Since it was presented in Mandarin only, microled-info.com caught up with Dr. Cheng to learn more about this trending subject and the company he started.

Q: Dr. Cheng, can you please tell us a little about your background, prior to starting Bolite?

I was a research engineer at Xerox PARC and helped develop surface micromachined microspring interconnects in a project funded by the U.S. Army Research in collaboration with Oracle. I was also a vital member of the team that successfully demonstrated the world’s shortest wavelength diode laser at the time, a 250 nm UV laser for military applications. With these experiences in both semiconductor laser processing and MEMS processing, I decided to start Bolite and build a team to develop state-of-the-art laser solutions for microprocessing applications.

Q: I must admit I’ve not heard of Bolite before. What differentiates you from other laser microprocessing companies?

QuantumDots-Info, a new knowledge hub to focus on quantum dots technologies for the display industry

Metalgrass has launched a new knowledge hub, QuantumDots-Info.com. Our new site focuses on QuantumDots technologies for the display industry. QDs are already used in many displays, and it is likely that the future will bring us more types of QD Displays, including QDEL, QD-OLEDs and QD-MicroLEDs that use quantum dots to convert blue light to red and green.

QuantumDots-Info brings you daily news, commentary, resources and updates about QDs in the display industry. You can subscribe to our weekly QD display newsletter here - and if you have not done so already, be sure to also subscribe to the free monthly MicroLED newsletter!

STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.
