Sundiode Develops Stacked 3-colour Micro-LEDs On A Single Wafer

Sundiode, a Silicon Valley based company developing micro-LED technologies for display applications, announced the achievement of fully stacked 3-colour (RGB) micro-LED pixel devices on a single wafer.

In the stacked-RGB pixel technology patented by Sundiode and developed in collaboration with KOPTI (Korea Photonics Technology Institute), a single pixel features three independently controlled micro-LED subpixels that are stacked vertically to allow full-colour emission from essentially the entire area of the pixel.

This pixel technology results in a very compact pixel structure and a substantial reduction in the pixel-transfer processing requirement for micro-LED display fabrication. In addition, the operation of a full-colour micro-display consisting of a pixel-array typically sized smaller than a penny is significantly enhanced due to increased utilisation of the extremely small pixel area.
