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 touch display substrate and a touch detection method thereof. The touch display substrate includes: a base substrate, and a photo-sensitive touch element and an Organic Light-Emitting Diode (“OLED”) device that are arranged on the base substrate sequentially. The photo-sensitive touch element includes a touch electrode layer, a photo-sensitive material layer, an insulating layer and an ITO layer that are arranged sequentially, wherein an orthographic projection of a touch sensing area of the touch electrode layer completely covers an orthographic projection of a pattern of the photo-sensitive material layer, and is within an orthographic projection of the ITO layer. The arrangement of the photo-sensitive touch element neither changes the sequence of manufacturing the layers of the display substrate, nor affects the illumination of the touch display substrate and is suitable for manufacturing a large-size touch screen.
