Problems solved by technology

However, for a display panel with a different shape, limited by the shape of the display panel, the lengths of the reference signal lines set in the display panel are different, and the corresponding loads are also different, which leads to the fact that the reference signal is on different reference signal lines. Different degrees of attenuation during uplink transmission lead to different reset degrees of sub-pixels electrically connected to different reference signal lines, which in turn leads to differences in luminous brightness of sub-pixels, resulting in split-screen phenomenon in the picture displayed on the display panel, which affects the display of the display panel. performance

Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and aims to improve the split screen phenomenon. The display panel comprises adisplay area provided with sub-pixels, a reference bus, reference signal lines, and a load compensation structure, wherein the reference signal lines are connected with the sub-pixels, at least partof the reference signal lines are connected with the reference bus through the load compensation structure, the load compensation structure comprises a load compensation wire connected with the reference bus, a signal transmission wire connected with the reference signal wire, and at least two switches connected between the load compensation wire and the signal transmission wire, the reference signal lines comprise a first reference line and a second reference line, and the first reference line is shorter than the second reference line. The display panel is advantaged in that in the load compensation structure connected with the first reference line, equivalent loads of the load compensation line and the signal transmission line which are connected through the switches are LA1, in the loadcompensation structure connected with the second reference line, equivalent loads of the load compensation line and the signal transmission line which are connected through the switch are LA2, and LA1 is larger than LA2.

Description

【Technical Field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In display technology, Organic Light Emitting Diode (OLED) display panels have been widely used due to their advantages such as fast response speed, wide viewing angle, high brightness, and low power consumption. [0003] The display area of ​​the OLED display panel is provided with multiple reference signal lines electrically connected to the sub-pixels for providing reference signals to the sub-pixels to reset the gates of the driving transistors and the anodes of the light-emitting diodes in the sub-pixels. However, for display panels with irregular shapes, limited by the shape of the display panel, the length of the reference signal line provided in the display panel is different, and the corresponding load is also different, which causes the reference signal to be on different reference signal lines. ...
