Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0050] As mentioned in the background art, existing display panels have serious mura problems and poor uniformity at low gray levels. In the prior art, the method of compensating the drive transistor is often used to improve the pixel circuit. The inventors found that the reason for the above problems lies in the large fluctuation and poor uniformity of the storage capacitor. The specific analysis is as follows:

[0051] figure 1 It is a schematic circuit diagram of an existing pixel circuit. see figure 1 , the p...

Abstract

The embodiment of the invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises an array circuit layer and a light-emitting device layer, the array circuit layer comprises a plurality of metal layers and a plurality of insulating layers, and each insulating layer is arranged between every two adjacent metal layers; one metal layer is provided with a first capacitor plate; the light-emitting device layer comprises a first electrode layer, and the first electrode layer is provided with a second capacitor plate; at least one insulating layer is arranged between the first capacitor plate and the second capacitor plate, and the first capacitor plate and the second capacitor plate form a capacitor. Compared with the prior art, the mura problem of the display panel is solved, the display uniformity is solved, and the display image quality is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technology, the application range of display panels is becoming wider and wider, and people's requirements for display panels are also getting higher and higher. In particular, the display quality of a display panel has always been one of the important indicators for consumers and panel manufacturers to measure the quality of a display panel. However, the existing display panels have serious mura problems and poor display uniformity at low gray scales, which affect the improvement of the display quality of the display panels. Contents of the invention [0003] Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device, so as to improve the mura proble...
