JBD demonstrates 2-million nits and 10,000 PPI Micro-LED microdisplays

Shanghai-based Micro-LED microdisplay developer JBD unveiled its latest Micro-LED microdisplay prototypes. JBD's panels can achieve a high brightness of 2 million nits coupled with very high pixel density (5,000 PPI) on a monochrome green display.

JBD also demonstrated an even high pixel density display (10,000 PPI). JBD can currently produce either monochrome or dual-color (red and green) microdisplays, and is developing full-color ones.

Mojo Vision developed a 14,000 PPI Micro-LED microdisplay

AR developer Mojo Vision announced that it developed a 14k sub-pixel PPI (1.8µm sub-pixel pitch) Micro-LED microdisplay, to power its upcoming AR platform. The microdisplay is a monochrome green one, that the company says is the smallest display ever developed at 0.48 mm diameter.

This prototype, according to Mojo Vision, demonstrates the capability that MicroLEDs have to create more seamless AR experiences. The company did not say how close it is to commercialize the display, but did say that it will release more details on its MicroLED displays and technology development at a "future date".

Glo partners with Kyocera and demonstrate a 1.8" Micro-LED display

US and Sweden based Micro-LED developer Glo has partnered with Japan-based display maker Kyocera to demonstrate a 1.8" Micro-LED display that features a resolution of 256x256 (200 PPI). For this demonstration panel, Kyocera provided the LTPS backplane and driving technology while glo provided its InGaN RGB micro-LEDs and its transfer technology.

Glo says its micro-LED technology enables the production of displays ranging from micro-displays to smartphone-sized panels, and have demonstrated several such panels at SID DisplayWeek 2019.

VueReal developed a 30,000 PPI micro-LED microdisplay, will start accepting orders for samples soon

Micro-LED microdisplay developer VueReal will start accepting orders for its first micro-LED display samples by June 2019. The company says that its patented self-aligned technology resulted in a robust and high yield microdisplay production process.

VueReal says that it developed Micro-LED microdisplays that achieve a brightness of 100,000 nits and a density of over 30,000 PPI - breaking its own world record of 6,600 PPI set in 2017.

In October 2018 VueReal announced that it has raised $8.5 million and that it will build an advanced nano technology fabrication center in Waterloo, Canada - which will include an integrated pilot production system that will use the company's proprietary sub-10 micrometer, high-efficiency, solid printing process at commercial volumes.

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.
