Abstract

The present invention provides a display panel and a display device. The display panel includes a common electrode layer and an auxiliary electrode layer, the common electrode layer forms a common electrode, the auxiliary electrode layer is patterned to form an auxiliary electrode line, and the two ends of the auxiliary electrode line are connected to the common electrode; By adding an auxiliary electrode line to the display panel, the common electrical signal flows into the auxiliary electrode line from one end of the common electrode, flows through the auxiliary electrode line, and then flows out of the common electrode from the other end, so that during the transmission of the common electrical signal, it can be seen The common electrode is connected in parallel with the auxiliary electrode line, and because the sheet resistance of the auxiliary electrode line is much smaller than that of the common electrode, the total resistance after the common electrode and the auxiliary electrode line are connected in parallel is much smaller than the resistance of the common electrode. , the resistance is reduced, and the voltage drop is reduced, that is, the present invention reduces the voltage drop on the common electrode line of the display panel, thereby improving the brightness uniformity of the display panel and reducing the power consumption of the display panel.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] The brightness uniformity of the display panel, as an important criterion for judging the display effect, needs to be strictly considered and controlled in the manufacturing process of the display device. [0003] However, in the design of the display panel, due to the voltage drop in the circuit, especially the voltage drop in the common electrode circuit, the brightness uniformity of the display panel is affected, and the power consumption of the display panel is also increased. [0004] Therefore, the existing display panel has the problem of excessive line voltage drop, which needs to be solved. Contents of the invention [0005] The invention provides a display panel and a display device to alleviate the problem of excessive line voltage drop in the existing display panel. [0006] In order to solve the above...
