Abstract

The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. A problem of uneven brightness of a display image can be solved. In the display panel, multiple first power supply lines extending in the first direction and multiple second power supply lines extending in the second direction are arranged in a display region. The first power supply lines and the second power supply lines cross each other and are connected to form an integrated net-shaped structure which is electrically connected with anodes of multiple OLEDs. At least one driving chip is arranged in a periphery region, and is electrically connected with the net-shaped structure. The net-shaped structure comprises multiple grids which are defined by the first power supply lines and the second power supply line in a crossed manner. In the direction away from the at least one driving chip, the density of the grids of the net-shaped structure in the farther place from the at least one driving chip is bigger. The display panel and the display device are used for display processes of an OLED.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. [0003] 【Background technique】 [0004] The display panel in the organic light-emitting diode (Organic Light-Emitting Diode, OLED) display product includes a plurality of display units distributed in a matrix in the display area, each display unit is provided with an OLED correspondingly, and the anode of the OLED is electrically connected to the power line. The line extends from the display area to the non-display area and is electrically connected with the driving chip, and the driving chip provides power for the OLEDs in the plurality of display units through the power line. [0005] However, in the process of power transmission from the driving chip to the OLED, due to the influence of the resistance of the power line itself and the electric charge consumed when the OLED emits light, the voltage values ​​at differen...
