A 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.
