Abstract
AbstractA 9.4‐inch 228‐ppi full‐color micro‐LED display using the flexible low temperature polysilicon thin‐film transistor (LTPS‐TFT) backplane has been successfully developed. In order to solve the interconnection of tiny micro‐LEDs, those size are less than 30 μm, we introduced the flip‐chip soldering technology for high‐resolution flexible micro‐LED displays. Contrast ratio of >1,000,000:1 with a brightness of 700 nits was realized by the full‐color micro‐LED display with uniform brightness and color shift free at any off‐axis viewing angles. These supreme micro‐LED visual performances will provide a more comfortable user experience for high‐resolution flexible automotive applications.
