Problems solved by technology

Due to the limitation of the size of the flexible circuit board, these driver chips may not be evenly arranged relative to the display area, which leads to a large length difference between the fan-out lines corresponding to different driver chips
As a result, the impedance of different fan-out lines is different, which in turn affects the signal transmission speed of the fan-out lines, resulting in uneven display defects

Abstract

The embodiment of the invention provides a display panel and a display device, and the display panel comprises a fan-out area, and the fan-out area comprises a first group of fan-out lines which comprise a plurality of first fan-out lines which are arranged in parallel along a first direction; the second group of fan-out lines and the first group of fan-out lines are adjacent in the first direction, the second group of fan-out lines comprise compensation lines and a plurality of second fan-out lines arranged in the first direction, the second fan-out lines comprise N short fan-out lines adjacent to the first group of fan-out lines, N is a positive integer larger than 0, wiring intervals are formed between the short fan-out lines and the first fan-out lines, and the first fan-out lines are adjacent to the compensation lines. The length of at least part of the short fan-out lines is smaller than that of the adjacent first fan-out lines, each short fan-out line in the N short fan-out lines is electrically connected with at least one compensation line, and the compensation lines extend to the wiring interval from the short fan-out lines. The display effect of the display panel can be improved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] In the display panel, the display panel includes a display area and a non-display area. Signal lines such as data signal lines and scanning signal lines are arranged in the display area to control the display of the picture. The non-display area is provided with a driving circuit and a fan-out lead. Used to transmit signals for signal lines such as data signal lines. A plurality of fan-out leads are usually arranged in a concentrated manner to form a fan-out area located in a non-display area. [0003] In a medium-to-large size display panel, multiple driver chips for connecting fan-out lines need to be provided, and each driver chip corresponds to a group of fan-out lines. Due to the limitation of the size of the flexible circuit board, these driver chips may not be evenly arranged relat...
