The JV will adopt Rohinni's proprietary high-speed MicroLED placement technology that is capable of placing 50 die-per-second (dps) with 10 micron accuracy at 99.999% die yields. BOE and Rohinni will initially focus on large panel applications (32-inch and up) for consumer electronic products in addition to all display sizes for industrial, automotive and other markets

Digitimes: San'an to start sampling micro-LED chips in January 2019

San'an Optoelectronics logoIn September 2018 we reported that China-based San'an Optoelectronics is gearing up to setup its first micro-LED epitaxial wafer and chip production line in Q1 2019.

According to Digitimes, San'an now plans to start sampling Micro LED chips as early as January 2019. San'an says that micro-LEDs are not mature yet, but early trial adoption will begin in the second half of 2019 - for movie theaters, TVs and automotive displays.

According to Digitimes, China-based Sa'nan Optoelectronics is gearing up to setup its first micro-LED epitaxial wafer and chip production line in Q1 2019. San'an developed 20-micron micro-LEDs, and the company is now aiming to develop 4-micron LEDs and 10-micro LED flip-chips.

According to the report, San'an aims to start small-volume micro-LED production to be used for wearables, automotive taillights and large-area displays. The company's green and blue micro-LEDs are ready for commercialization, but its red chips still require development.

Rohinni and Magna Electronics announce a new JV to develop flexible Micro-LED lighting panels for automotive applications

US-based Rohinni announced a new joint-venture with Magna Electronics to develop flexible mini-LED and micro-LED based lighting devices for the automotive market.

The new JV, controlled by Magna Electronics will be called Magna Rohinni Automotive Electronics and will be based in Holly, Michagan, US. In addition to the JV, Magna also made a minority equity investment in Rohinni.

Lumens demonstrates two Micro-LED automotive HUD prototypes

Korea-based LED developer Lumens is developing a Micro-LED based HUD for the automotive aftermarket, and at CES the company demonstrated two prototypes, a Direct-HUD and a project-based one.

Lumens MicroLED HUD prototype (CES 2018)

Lumen's HUDs use three monochrome (RGB) Micro-LED panels, which combined can reach 100,000 nits. The project one uses a projection lens for the image magnification. The smaller HUD uses the Micro-LED directly as the output to the combiner.

Jasper Display unveils a new silicon wafer specialized for micro-LED displays

Jasper Display LogoTaiwan's Jasper Display Corp (JDC) unveiled its new silicon micro-LED backplane, the eSP70, which reportedly features high brightness and contrast possible. JDC's eSP70 is capable of FHD (1920x1080) resolution using a pixel pitch of 8 um and JDC says that it offers excellent current uniformity via a proprietary current source pixel (uniformity is better than 1% across the array).

JDC demonstrated the eSP70 using micro-LEDs provided by glō. The company says that this is the industry's first specialized micro-LED ready silicon. JDC's technology can be customized and it can be suitable for a wide range of applications, from AR headsets to automotive headlights. JDC's eSP70's 8" are now shipping.

Innolux unveils an automotive 10.1" mini-LED display prototype

Taiwan's Innolux demonstrated a new prototype mini-LED display. The 10.1" panel features a resolution of 1540x720 (168 PPI) and it seems to be a monochrome white display. Innolux hopes to commercialize such displays by 2020.

Innolux says that this type is very suitable for automotive applications - as it has an almost infinite contrast (similar to OLED displays) and it can also work in the demanding temperatures required by the automotive industry. Innolux hopes that such mini-LED displays can find a market and be a bridge before the company can develop micro-LED displays with higher densities and increased brightness.

PlayNitride starts to ship micro-LED panel samples, working with 5-6 customers

PlayNitride began sampling micro-LED panels, shipping these to 10-20 potential customers in Q4 2017. The company's chairman and CEO, Charles Li, says that 5-6 of these customers are continuing the developing of micro-LED modules based on these panels.

In September 2017 we reported that Charles Li said that Micro-LED displays are not as challenging as originally expected, and the company aims to start trial production of Micro-LED displays in the second half of 2017 - it's great to see the company progressing as planned. PlayNitride says that it achieved mass transfer and placement yield rates of over 99% in its lab.

Lumens starts to produce 0.57" and 100" micro-LED displays, to be demonstrated in CES 2018

Lumens logoAccording to LEDsInside, Korea-based LED developer Lumens has begun to produce small and large-area micro-LED display prototypes, and it plans to demonstrate these prototypes at CES 2018 (January 2018).

Lumens focuses on automotive HUD displays and digital signage. The small HUD display is a 0.57-inch VGA (640x480) display (either VGA or 720p, it's not clear) that uses 8 μm LED chips while the signage display is a 100" panel that uses LEDs which are 300x100 μm.

Lumens aims to launch an automotive Micro-LED HUD by the end of 2017

Lumens logoThe Korean Herald posted an interesting interview with Jung Tae-hong, the president of Korea-based LED developer Lumens. Jung reveals that the company is developing an HD Micro-LED based automotive Heads-Up-Display (HUD), with plans to release its first such display by the end of 2017.

Lumens believes that Micro-LED displays are very suitable for HUDs as they can offer better usability under direct sunlight compared to LCD or OLED displays, and they can withstand high temperatures. In 2017 Lumens will launch a combiner-type HUD for the automotive aftermarket, and will introduce a built-in version within 2-3 years.
