Problems solved by technology

However, the current optical compensation technology uses a CCD camera to collect the brightness of each pixel to compensate. This method requires relatively large equipment, so it is limited to one-time compensation before the manufacturer ships, and cannot address the brightness difference caused by long-term product aging. make compensation

Abstract

The invention provides a display panel, a brightness compensation method and a display device. The display panel comprises an array substrate, a light-emitting layer, a plurality of optical film layers and a photoelectric sensor. The light-emitting layer is located on one side of the array substrate, the array substrate is used for driving the light-emitting layer to emit light, the optical film layers are located on the side, away from the array substrate, of the light-emitting layer, and light emitted by the light-emitting layer forms waveguide light on the array substrate and/or the optical film layers. The photoelectric sensor is used for obtaining the waveguide light so as to perform brightness compensation on light emitted by the light-emitting layer according to data of the waveguide light. According to the display panel provided by the invention, the waveguide light formed by the light emitted by the light-emitting layer on the array substrate or the optical film layers can be obtained through the arrangement of the photoelectric sensor so that the brightness compensation can be performed on the light emitted by the corresponding light-emitting layer according to the brightness of the waveguide light, and the brightness uniformity of the display panel is ensured; and the visual experience of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, and in particular to a display panel, a brightness compensation method and a display device. Background technique [0002] Organic light-emitting diode display (Organic Light-Emitting Diode, OLED) is a self-luminous display device that emits light through OLED to display images. It is thinner and lighter than liquid crystal display (LCD), and has higher display characteristics. It is attracting much attention as a next-generation display device for portable electronic devices. [0003] Generally, the active driving method of OLED devices adopts voltage driving. For voltage-driven compensation methods, it can be divided into electrical compensation and optical compensation. Among them, optical compensation directly uses brightness as the compensation object. After compensation, it can achieve the advantages of uniform brightness and height. Therefore, optical compensation is given high hopes and is ...
