Abstract

The invention discloses a display panel and a display device. The display panel is provided with a display area and a non-display area; the display panel comprises a touch substrate, the touch substrate comprises a touch integrated circuit located in the non-display area and a touch sensing block located in the display area, and the touch sensing block is electrically connected with the touch integrated circuit through a signal line; the signal line comprises a first section located in the display area and a second section located in the non-display area, and the sectional area of at least part of the second section is larger than that of the first section. According to the display panel provided by the embodiment of the invention, the resistance between the touch sensing block and the integrated circuit is reduced by increasing the sectional area of the touch signal line connected between the touch sensing block and the integrated circuit, so that the influence on the touch performance of the display panel due to overlarge resistance of the touch signal line is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of technology and the diversification of people's needs, touch functions are increasingly applied to display devices such as mobile phones, tablet computers, and vehicle display screens. A display panel in an existing display device usually includes a touch sensing block and an integrated circuit, and the touch sensing block and the integrated circuit are connected through a touch signal line to realize signal transmission. As the product size continues to increase, the length of the touch signal line will also increase, and the resistance caused by the corresponding wiring will also increase. Excessive resistance will affect the transmission of signals between the touch sensing block and the integrated circuit, thereby affecting the touch performance of the display panel. Conte...
