70‐1: Distinguished Paper: 9.4‐inch 228‐ppi Flexible Micro LED Display

9.4‐inch 228‐ppi full‐color micro LED display using the flexible LTPS‐TFT backplane has been successfully developed. In order to solve the interconnection of tiny micro LEDs, those size are less than 30um, we introduced the flip‐chip soldering technology for high resolution flexible micro LED displa...

Zusammenfassung:9.4‐inch 228‐ppi full‐color micro LED display using the flexible LTPS‐TFT backplane has been successfully developed. In order to solve the interconnection of tiny micro LEDs, those size are less than 30um, we introduced the flip‐chip soldering technology for high resolution flexible micro LED displays. Contrast ratio of >1,000,000: 1 with 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 be provided more comfortable user experience for high resolution flexible automotive applications.
