JBD unveils a 1 million nits MicroLED microdisplay

Shanghai-based Micro-LED microdisplay developer JBD demonstrated its latest Microdisplay that achieve an extremely high brightness - 1 million nits. The display resolution is VGA. JBD is already offering its monochrome VGA micro-LED microdisplays commercially (but we're not sure if these are the 1 million nits ones).

JBD's current micro-LED process still suffers from low yields, but the company hopes to achieve at least a 70% yield in the future, which will enable it to bring prices down to about $10 to $20 per display.

PlayNitride demonstrates micro-LED prototypes at SID 2018

Taiwan's PlayNitride demonstrates two Micro-LED prototypes at SID 2018. The first one is a small 0.89" 64x64 (105 PPI) panel with a brightness of 800 nits. All of the LED chips in this display were transferred in three shots (one shot per color). The pixel size in this display is 0.243 mm.

The second display is a larger panel - 3.12" 256x256 (116 PPI). Due to the larger number of LEDs (total of 786K LEDs) PlayNitride had to use 24 shots to transfer all three colored chips. The pixel size in this larger display is 0.219 mm.

X-Celeprint demonstrates a 5.1" 70 PPI Micro-LED display

Ireland-based micro-transfer printing developer X-Celeprint demonstrated a 5.1" Micro-LED display in a private demo room at SID Displayweek.

X-Celeprint's display has a low resolution - the pixel density is 70 PPI, which means the resolution is around 300x200. The display uses micro ICs to control and compensate each pixel (this is not a TFT display). X-Celeprint says it intends to spin off a new display-focused company within the next 12 months.

AUO demonstrates a 8" 169 PPI Micro-LED display prototype

AUO demonstrated a micro-LED display, which it says is the world's highest resolution full-color TFT micro-LED.

AUO 8'' Micro-LED prototype (SID 2018)

The 8" panel features a resolution of 1280x480 (169 PPI). The micro-LEDs use blue LED chips with color conversion, on an LTPS backplane. AUO did not disclose any roadmap to commercialize this technology.

JBD details the company's micro-LED technology and plans for 2018-2019

Shanghai-based JBD is developing micro-LED based Microdisplays for near-eye and image projection applications, using the company's proprietary hybrid monolithic integration technology. JBD received a $10 million investment and developed a 5,000 PPI micro-LED array, with plans to reach 10,000 PPI.

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.
