Abstract:
A display panel and a manufacturing method therefor, and a display device. The display panel comprises a substrate (11); a pixel unit array (12), arranged on a first side of the substrate (11), each pixel unit in at least a portion of pixel units (20) in the pixel unit array comprising a light emission layer (22), and an anode layer (21) and a main cathode layer (23) arranged on either side of the light emission layer (22), the anode layer (21) being closer to the substrate (11) than the main cathode layer (23), and the main cathode layer (23) being able to transmit light; and a sensor array (13), arranged on the side of the pixel unit array (12) away from the substrate (11), each sensor (30) sensing light emitted by a corresponding pixel unit (20). In the present display panel, pixel luminous intensity can be detected even though the sensors (30) are provided on the non-light-emitting side of an OLED panel.
