Abstract

The invention discloses a display panel and a display device, which belong to the technical field of display. The display panel comprises a substrate, a pixel circuit layer, a light-emitting element and an auxiliary wiring layer, wherein the pixel circuit layer comprises a plurality of pixel circuits, the pixel circuits are electrically connected with the power signal lines, the light-emitting elements are electrically connected with the pixel circuits in a one-to-one correspondence mode, and the auxiliary wiring layer is located on the side, away from the pixel circuit layer, of the substrateand comprises at least one auxiliary signal line; the power signal lines and the auxiliary signal lines are electrically connected through via holes, and at least part of the power signal lines are connected with the auxiliary signal lines in parallel or connected with other similar power signal lines in parallel through the auxiliary signal lines. The display device comprises the display panel.According to the display panel and the display device, at least part of the power signal lines on one side of the substrate are connected with other signal lines in parallel, so that the impedance ofthe power signal lines is reduced, the display brightness uniformity of the display panel can be improved, and the visual experience effect of a user can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Common display panels include liquid crystal display panels, plasma display panels, organic light-emitting diode display panels, etc. These display panels can be used in mobile phones, camcorders, notebook computers, desktop monitors, and projection TVs, etc. in consumer electronics or computer products. Organic light emitting diode (Organic Light Emitting Diode, referred to as OLED) display is generally lighter and thinner, and has brighter colors and stronger contrast, and can be used to realize flexible display and transparent display, so it is widely used in the display industry. [0003] Generally speaking, the OLED display itself is a current-driven device, and its luminous brightness is determined according to the magnitude of the passing current. Therefore, when the OLED is applied to ...
