VueReal demonstrates a scalable process to make RGB microLED cartridges for printing next generation displays

VueReal has announced that its multi device cartridge structure enables faster population of a display with higher yield and higher alignment accuracy. 

Most applications such as displays require more than one sub pixels with different devices per sub pixels. In case of microLED display, red, green, and blue microLEDs are required for each pixel.

Moreover, most of these devices are fabricated in different environments using different material sets for higher performance. The common approach is to transfer each device independently to a large substrate. For a 4K microLED display, that means  three repetition of transfering of 8 million LEDs into a large substrate which can result in low throughput, low yield and high misalignment.
