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

PCB-based microLED panels are designed to seamlessly combine displays into large screens; TFT-based panels can form curved and transparent surfaces; and Si-based panels have ultra-high brightness and resolution and can be used in augmented reality glasses and automotive HUDs (windshield indicators), PlayNitride explained.

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

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

PlayNitride is also showing a 0.39-inch silicon-based microLED panchromatic panel with 1,411 pixels per inch and 50,000 nits of brightness for augmented reality glasses.

Touch panel manufacturer General Interface Solution (GIS) is demonstrating a 121-inch interactive LED vform display combining multiple transparent LED thin-film panels with a curved surface, as well as a 55-inch transparent OLED touch display.

The state-sponsored Industrial Technology Research Institute (ITRI) is demonstrating microLED low-diffraction transparent AM (active matrix) technology, a technology that is compatible with existing display panel manufacturing processes.

As for mini/microLED equipment, Stroke PAE presents equipment for mass transfer, laser joining, sorting and placement of mini/microLED chips, and Saultech Technology demonstrates MX-10 equipment used to combine sorting, blending and placement of miniLED chips into a single process.
