研究目的
To demonstrate a new active matrix Mini LED full color display with high transmittance over 60%, which has a pixel pitch of 0.55mm, using RGB Mini-LEDs and chip on glass with top gate structure IGZO TFT backplane.
研究成果
We demonstrated a 8-inch full color AM Mini-LEDs transparent display with IGZO TFT backplane, which exhibits high transmittance over 60%, and it achieved over 100% NTSC color gamut.
研究不足
The fabrication was limited by the numbers of IC driving and the thickness of PCB. Moreover, it is impossible to achieve a transparent display in case of using PCB as a backplane.
