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: A method for fabricating a touch display substrate and a touch display substrate are provided to solve the problem that existing touch electrodes of the micron-scale line width cannot meet the high PPI requirement. The fabrication method includes: forming functional layers of an organic light-emitting diode (OLED) device on a base substrate sequentially to obtain an OLED substrate; and forming a linear touch electrode with a nano-scale line width on the OLED substrate by electronic sputtering and transferring.

Abstract: A display driving unit circuit, a driving method, a display driving circuit and a display device are provided. The display driving unit circuit includes a pixel driving circuit and a light-emission control signal generation circuit. The light-emission control signal generation circuit is coupled to the pixel driving circuit. The pixel driving circuit is to drive a pixel to emit light. The light-emission control signal generation circuit is to supply a display light-emission control signal to the pixel driving circuit at a display stage to enable the pixel in a displaying mode and supply a fingerprint detection light-emission control signal to the pixel driving circuit at a fingerprint detection stage to enable the pixel in a fingerprint detection light-emission mode at the fingerprint detection stage. The display stage and the fingerprint detection stage are different time periods.
