We proposed a new full-color display framework QD-OLEDs, where blue OLEDs are used as pump light, and red green QDs printed on color filters conversion layers.
Abstract Combining blue micro‐light‐emitting diodes (LEDs) with color conversion layers (CCLs) is a promising approach to develop efficient full‐color displays. However, no such practical display reported so far potentially because of two major challenges, i.e., rarely available materials and severe crosstalk effect among adjacent pixels due the thick sapphire substrates LED chips. Here, micro‐LED prototype by combining rationally designed micro‐LEDs backlight CsPbBr 3 perovskite CdSe QDs as...
