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

Embodiments of the present invention provide a display panel and a display device, relate to the field of display technology, and improve split-screen phenomena. The display panel includes: a display area, the display area is provided with sub-pixels; a reference bus; reference signal lines connected to the sub-pixels, at least part of the reference signal lines are connected to the reference bus through a load compensation structure; the load compensation structure includes a load connected to the reference bus Compensation wiring, signal transmission wiring connected to the reference signal line, at least two switches connected between the load compensation wiring and the signal transmission wiring; the reference signal line includes a first reference line and a second reference line, the first The reference line is shorter than the length of the second reference line. In the load compensation structure connected to the first reference line, the equivalent load of the load compensation line and signal transmission line connected through the switch is LA1. In the load compensation structure connected to the second reference line , the equivalent load of the load compensation wiring and the signal transmission wiring connected through the switch is LA2, and LA1>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 the display technology, the organic light emitting diode (Organic Light Emitting Diode, OLED) display panel has been widely used because of its advantages such as fast response speed, wide viewing angle, high brightness, and low power consumption. [0003] A plurality of reference signal lines electrically connected to the sub-pixels are provided in the display area of ​​the OLED display panel 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 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 th...
