Project Description

Product Specification of JD27ET


The JD27ET is an 8” silicon wafer of JD67ET die. The JD67ET is a current source pixel array backplane designed for realizing emissive Micro LED and OLED products. Up to 2.0 Amps of current is available for high brightness and global dimming for high contrast. Digital modulation allows for stable color.
Pixel current and voltage are fully programmable.

The JD67ET is ideally suited for LED and OLED applications such as AR and HUDs.
