LTPS image sensor (LIS) driven by active pixel senor (APS) circuit based on LTPS backplane technology is demonstrated. Optical solution for LCD with in‐cell optical fingerprint scanning function is discussed. A 400PPI LTPS‐TFT LCD with in‐cell touch and in‐cell screen fingerprint scanning function is designed to realize fingerprint image capture when finger is 1.0mm height over the LIS array.
