PlayNitride is exhibiting three types of microLED technology respectively based on PCB, TFT and Si backplanes at 2022 Touch Taiwan during April 27-29.

PCB-bsased microLED panels are for seamlessly stacking displays into big screens; TFT-based panels can form curved and transparent surfaces; and Si-based panels feature ultra-high brightness and resolution and can be used in AR glasses and automotive HUDs (head-up displays), PlayNitride explained.

PlayNitride is exhibiting a large display formed by many PCB-based microLED panels with wide color gamut of 116% NTSC, brightness of 2,000nits and a pixel pitch of 0.43mm.

For automotive displays, PlayNitride is showcasing a 9.8-inch TFT-based microLED panel with transparency of 65-70%, a 11.6-inch TFT-based 24:9 2.5K microLED panel and a 1.58-inch TFT-based square-shaped micro LED panel.

PlayNitride is also showcasing a 0.39-inch Si-based panchromatic microLED panel with resolution of 1,411ppi and brightness of 50,000nits for AR glasses.

Touch panel maker General Interface Solution (GIS) is exhibiting a 121-inch interactive LED display vform by stacking many curved-surface transparent LED thin-film panels as well as a 55-inch transparent touch OLED display.

Government-sponsored Industrial Technology Research Institute (ITRI) is exhibiting technology of low-diffraction transparent AM (active matrix) microLED, with the technology compatible with existing display panel manufacturing processes.

For mini/microLED equipment, Stroke PAE is exhibiting equipment of mass transferring, laser bonding, sorting and placing mini/microLED chips, while Saultech Technology is showcasing MX-10 equipment used to combine sorting, mixing and placing miniLED chips into a single process.
