Abstract

The present application provides an array substrate, a display panel and a display device. The array substrate includes a base substrate, a driving circuit layer and a plurality of light emitting units. The driving circuit layer is arranged on the base substrate, including photosensitive devices. A plurality of light-emitting units are arranged on the driving circuit layer, including a first electrode, a transparent electrode, a light-emitting layer and a second electrode arranged in sequence from the driving circuit layer to a direction away from the base substrate, and the position of the first electrode corresponding to the photosensitive device is provided with Through the through hole of the first electrode, the transparent electrode covers the first electrode and fills the through hole, allowing the light emitted by the light-emitting layer to pass through and irradiate the photosensitive device. The display panel includes an encapsulation layer and an array substrate, and the encapsulation layer is arranged on the array substrate. The display device includes a display panel.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate, a display panel and a display device. Background technique [0002] OLED (Organic-Light-Emitting Diode, Organic Light-Emitting Diode) displays images by emitting light during the recombination process of electrons and holes in organic materials. Due to its simple preparation process, low cost, fast response speed, easy realization of color display and large-screen display, low power consumption, high luminous brightness, wide range of working temperature adaptability, thinness and easy realization of flexible display, etc., it has a wide range of applications. Application prospect. However, there are also some problems in the display technology using OLED. The general driving circuit includes a driving transistor for driving the OLED, and the OLED may display uneven brightness after long-term operation. It may be due to the drift of the thresh...
