Embodiment Construction

[0027] 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 herein 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, the drawings only show some but not all structures related to the present invention.

[0028] As described in the background art, the existing display devices usually have problems such as poor display quality of black images and flickering of the screen, which seriously affect the display effect of the display device. The inventors have found that the reasons for the above problems are as follows: In the pixel circuits of the existing display devices, thin film transistors made of low temperature polysilicon (LTPS) materials are generally used to drive the light-emitting devices for light-emitting display, which is ...

Abstract

Embodiments of the present invention disclose a display panel and a display device. The display panel includes: a substrate; an active layer and at least two metal layers, located on one side of the substrate, the active layer and the at least two metal layers form a pixel circuit in the display panel; between the active layer and the at least two metal layers , and an insulating layer is included between the adjacent metal layers, and the insulating layer is provided with vias connecting the active layer to any two of the at least two metal layers; the pixel circuit includes a first pixel circuit and a second pixel circuit , the numbers of thin film transistors and capacitors in the first pixel circuit and the second pixel circuit are equal, and the number of vias in the first pixel circuit is less than the number of vias in the second pixel circuit. The technical solutions of the embodiments of the present invention reduce the number of defect states in the related film layers of the thin film transistor caused by the etching of the via holes by reducing the number of via holes in the display panel, thereby reducing the leakage current generated by the thin film transistor and improving the display Effect.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for the performance of display devices. Existing display devices usually have problems such as poor display quality of black images and flickering of the screen, which seriously affect the display effect of the display device. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a display panel and a display device, so as to reduce the leakage current of the thin film transistor, thereby improving the display effect. [0004] In a first aspect, an embodiment of the present invention provides a display panel, including: [0005] base; [0006] an active layer and at least two metal layers located on one side of the substrate, the active layer and the at least ...
