Problems solved by technology

[0002] In recent years, touch quality is a very important factor among the factors affecting the quality of display panels. An important touch technology for display panels is self-capacitive touch. For self-capacitive touch, the touch electrodes connected The fan-out method of the touch leads on the same layer will affect the size of the lower border of the display panel. For example, if the bottom row of touch electrodes is reduced to allow the fan-out of the touch leads, the number of touch leads running in the display area will be affected. Due to the limitation, the horizontal winding of some touch leads still needs to pass through the lower frame, which is not conducive to the narrow frame

Abstract

The embodiment of the invention discloses a display panel. The display panel comprises a display area and a non-display area, the display panel comprises a plurality of touch electrodes arranged at intervals and touch leads overlapped with the touch electrodes, each touch electrode is electrically connected with the corresponding touch lead, the plurality of touch electrodes comprise a plurality of touch electrode columns, and the touch electrode columns are arranged in the non-display area. At least part of the touch leads comprise first line segments and second line segments which are arranged in different directions, and in the at least part of the touch leads, the first line segments of the same touch lead are overlapped with the multiple touch electrodes in the corresponding touch electrode columns; the second line segments are at least overlapped with the touch electrodes, closest to the non-display area, in the corresponding touch electrode columns; the first line segments of the same touch lead are overlapped with the multiple touch electrodes in the corresponding touch electrode column, and the second line segments are at least overlapped with the touch electrodes closest to the non-display area in the corresponding touch electrode column, so that the fan-out space and the wiring space of the touch lead are increased, and the width of a lower frame is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel. Background technique [0002] In recent years, touch quality is a very important factor among the factors affecting the quality of display panels. An important touch technology for display panels is self-capacitive touch. For self-capacitive touch, the touch electrodes connected The fan-out method of the touch leads on the same layer will affect the size of the lower border of the display panel. For example, if the bottom row of touch electrodes is reduced to allow the fan-out of the touch leads, the number of touch leads running in the display area will be affected. However, the horizontal winding of some touch leads still needs to pass through the lower frame, which is not conducive to the narrow frame. [0003] Therefore, there is an urgent need for a display panel to solve the above technical problems. Contents of the invention [0004] The present invention provides ...
