Abstract: The present disclosure provides a touch display panel, a flexible display panel and a display apparatus. In one embodiment, light sensitive effect-based photo-sensitive diodes and switching transistors for controlling signal output of the photo-sensitive diodes are integrated in the display panel. Once a touch operation of an object (e.g., a finger) is implemented on a surface of the display panel, the photo-sensitive diode in a corresponding position can convert a sensed light intensity difference into an electrical signal difference to achieve detection of the touch operation.

Abstract: The disclosure provides a palmprint recognition circuit based on a LTPS technology, a palmprint recognition method and a display screen. The palmprint recognition circuit comprises an optical signal collecting unit, configured to collect an optical signal indicating a palmprint information and convert the collected optical signal into a current signal; a current signal amplifying unit, configured to amplify the converted current signal; and a current signal detecting unit, and configured to detect an intensity of the amplified current signal which indicates a ridge line or a valley line of the palmprint in the palmprint information. Therefore, it can solve the problem of having no palmprint recognition circuit and method for a LTPS-TFT display panel. This can eliminate an influence of a change of parasitic capacitance on the recognition result, wherein the change of parasitic capacitance is caused by a change of a wiring manner in the circuit.
