Abstract

The application discloses a display panel. The display panel comprises a base material; a first touch electrode, a first touch signal line and a second touch signal line which are arranged on the base material, wherein the first touch electrode is electrically connected with the first touch signal line; an insulating layer which covers the base material, the first touch electrode, the first touch signal line and the second touch signal line; a second touch electrode located on an insulating layer, wherein an extending direction of the second touch electrode is intersected with an extending direction of the first touch electrode, and each second touch electrode is electrically connected with at least one second touch signal line through a via hole, the second touch signal line is insulated from the first touch electrode and the first touch signal line, and at least one second touch signal line is formed between two first touch electrodes. At least one second touch signal line is formed between two first touch electrodes through the implementation way, the space of a non-display area occupied by the second touch signal line can be reduced, thereby benefiting the realization of the design of a narrow frame.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] At present, existing touch display panels are mainly divided into mutual-capacitance display panels and self-capacitance display panels. The mutual capacitive display panel usually includes touch emitting electrodes and touch sensing electrodes. The extending direction of the touch emitting electrode intersects with the extending direction of the touch sensing electrode, and the touch position is determined by the mutual capacitance formed in the overlapped area. [0003] The touch emitting electrodes and the touch sensing electrodes generally respectively transmit touch driving signals and touch sensing signals through touch signal lines. The touch signal lines electrically connected to the touch sensing electrodes are usually routed along the non-display area of ​​the display panel. Due to the large number of touch si...
