Raysolve shows new microLED microdisplay prototypes at CES 2024

Hong Kong based microLED microdisplay developer Raysolve Technology demonstrated two new microLED microdisplay prototypes, 0.11" (320x240) and 0.22" full color displays. The displays feature a density of 7,200 PPI and a brightness of up to 150,000 nits (full color). 

The displays are based on blue LEDs, with the company's proprietary Quantum dot photoresist (QDPR) process. Raysolve says it has optimized its QD process and increase the color gamut of its displays - which now achieve 147.2% sRGB, 104.3% NTSC and 108.5% DCI-P3.

XTPL launches an ultra-precise inkjet printing platform with support for microLED interconnection printing

Poland-based inkjet printing pioneer XTPL has launched its latest printing system, the Ultra-Precise Dispensing (UPD) System that enables the printing of high-precision electronically conductive or insulating structures.

The new systems are suitable for industrial production, and XTPL is targeting the display market, and specifically the microLED display market with its new systems. For microLED developers, UPD offers the ability to deposit precise conductive interconnections, supporting the integration of the microLEDs into heterogeneous microelectronic systems. These interconnections manage control, driving, and power distribution for microLEDs, expanding potential applications in AR/VR devices, smartwatches, automotive displays, and more.

Q-Pixel developed the world's smallest full color microLED pixel, and demonstrated a 10,000 PPI display

US-based Q-Pixel announced that it has developed the world's smallest full-color pixel (1 micron) and demonstrated a 10,000 PPI microLED microdisplay based on its proprietary tunable polychromatic microLED technology (which it brands as TP-LED). 

Q-Pixel's technology enables a single-pixel color-tunable microLED device, and the company's displays are produced using a monolithic process. In May 2023, the company announced a 5,000 PPI full-color microdisplay, so this is fast progress only a few months later. Q-Pixel is a MicroLED Industry Association member.

Q-Pixel announces a 5000 PPI microLED microdisplay based on its color-tunable single-pixel technology

US-based Q-Pixel announced that it has developed a 5000 PPI full-color microLED microdisplay, based on its proprietary Polychromatic microLED technology.

Q-Pixel's technology enables a single-pixel color-tunable microLED device. The displays are produced using a monolithic process. As the company is still in stealth-mode, we do not have more information, it will be interesting to know how this technology compares to Porotech's DPT color-tunable microLED technology.

Foxconn, Ennostar and Unikorn Semiconductor jointly develop microLED microdisplays

Hon Hai Precision Industry (Foxconn) has announced that it has developed a new microLED microdisplay, in collaboration with Ennostar and Unikorn Semiconductor (a part of Ennostar). The company is showcasing the display at Touch Taiwan 2023 - a monochrome blue 0.12" 6500 PPI 200,000 nits display.

Foxconn says that the companies have optimized the structure of the microLED chips in a join project, and developed a new thin film protection technology tat reduces surface defects, improves external quantum efficiency, and increases product reliability. Foxconn has also developed its own quantum dots based color conversion technology that enables it to convert the display to full-color (that achieved a PPI of 3,600).
