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 is reported so far potentially because of two major challenges, i.e., rarely available color conversion materials and severe crosstalk effect among adjacent pixels due to the thick sapphire substrates of LED chips. Here, a full‐color micro‐LED display prototype by combining rationally designed blue micro‐LEDs backlight with CsPbBr3 perovskite and CdSe QDs as green and red CCLs, respectively, is presented. The color gamut of the fabricated display can reach as high as 129% of the National Television Standards Committee (NTSC). Notably, the color gamut can still reach 126% NTSC even when only green light is converted through perovskite CCL while the other two colors are achieved from conventional micro‐LEDs. This is the first demonstration on employing perovskite materials as CCL in full‐color micro‐LEDs display.

Mini-LED and micro-LED are expected to be the next-generation display by virtue of their diverse applications. In this study, an 8-inch flexible mini-LED display was fabricated using an indium-gallium-zinc oxide (IGZO) thin-film transistor (TFT) backplane that adopted a top-gate structure, with a pixel pitch of 0.55 mm and a resolution of 320 x 160, 46 PPI. With colorless polyimide (CPI) as the substrate, the mini-LED panel has a thickness of less than 0.2 mm, and a transmittance is over 60%. The world's first 8-inch, full-color, flexible mini-LED with IGZO-TFT backplane is demonstrated.

In this paper, the first time reported the full color active matrix micro‐LEDs (AMLEDs) display with high transparent over 40% which is based on top gate IGZO TFT (Thin film transistor) backplane. This AMLEDs display was successfully developed with flip chip RGB micro‐LEDs that can achieve more than 108% NTSC gamut, while the display is also brighter than 400nits.

In this paper, we presented a active matrix Mini LED full color display with high transmittance over 60%. A 8-inch display with RGB Mini-LED with IGZO TFT backplane was demonstrated, which is 46 PPI pixel resolution and 256 grayscales and the pixel pitch is less than 0.55mm. It is the first time to realized the full color display based on RGB Mini-LEDs and chip on glass with top gate structure IGZO TFT backplane. We believe that it is a good breakthrough and demonstration for developing large-size Micro LED backplane and displays.

We successfully realized 14 inch flexible LCD display with FHD resolution. The LCD panel has the thickness less than 0.3 mm, which using new type of colorless PI as substrate. The flexibel LCD is IPS mode. The key technology includes the conbination of indium gallium zinc oxide (IGZO) TFT , Color filter on Array substrate(COA)and Black Photo Spacer(BPS).
