Problems solved by technology

[0007] However, usually the cover plate of the display device is made of transparent material, such as glass, organic film, etc., so that the light of the electroluminescent element can pass through; however, the photosensitive detection element and its driving circuit are opaque; therefore, the The photosensitive detection element and its driving circuit in the external optical compensation sub-circuit will block the light of the electroluminescent element, resulting in a lower aperture ratio of the top-emitting OLED device, thereby affecting the display effect of the display device

Abstract

The invention discloses a display device with a built-in pixel compensation function, a display panel and a manufacturing method thereof. The display panel comprises a substrate, an electroluminescentEL device, a driving backboard of the EL device arranged between the EL device and the substrate, and a light detection unit arranged between the driving backboard and the substrate; a light hole arranged in a reflecting anode of the EL device is opposite to a photosensitive detection element in the light detection unit; the light detection unit is used for detecting a brightness signal of the ELdevice through the light hole, and an electric signal which is used as the pixel compensation evidence is output. The real-time Demura compensation is performed by applying the display device, the light of the EL element cannot be shielded, an opening rate of the top emission OLED device is improved, and a display effect of the display device cannot be influenced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device with a built-in pixel compensation function, a display panel and a manufacturing method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) or AMOLED (Active-matrix organic light-emitting diode, Active Matrix Organic Light-Emitting Diode) as a current-mode light-emitting device has been increasingly used in high-performance displaying. Due to its self-luminous characteristics, it has many advantages compared with LCD, such as high contrast, ultra-thin and light. However, brightness uniformity and afterimage are still the two main problems it faces at present. To solve these two problems, in addition to the improvement of the process, compensation technology has to be mentioned. Compensation methods can be divided into two categories: internal compensation and external compensation. Internal compensa...
