Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a substrate; a display device arranged on the substrate; and a touch control device arranged on the side, away from the substrate, of the display device, wherein the touch control device comprises a bridging layer, an insulating layer and a touch control electrode layer which are sequentially arranged in a stacked mode in the light emitting direction of the display panel, the bridging layer comprises a plurality of bridge-crossing electrodes, and the touch control electrode layer comprises touch control electrodes distributed in the first direction or the second direction; the second direction intersects with the first direction; each touch electrode comprises a touch electrode part, and the touch electrode part and the span bridge electrode are at least partially overlapped in the direction perpendicular to the plane where the display panel is located; each touch electrode part comprises a plurality of touch metal parts which form a metal grid shape and are electrically connected with one another, the bridge-crossing electrode comprises a plurality of bridge-crossing metal parts, and at least part of the touch metal parts extending in the same direction cover the bridge-crossing metal parts in the direction perpendicular to the plane where the display panel is located.

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] With the progress of the information age, the touch screen technology has gradually replaced the key technology to become the mainstream technology of mobile terminals and the like. Touch screen technology is a technology that detects the touched position (in the form of coordinates) and sends it to the controller when a finger, pen, etc. touch the touch screen installed on the front of the display device, so as to determine the input information. At present, the application range of touch screen is very wide, and the main products include mobile terminals such as touch mobile phones and notebook computers, as well as human-machine display interfaces in the industrial automation industry. [0003] In order to realize the touch function of the display device, it is usually necessary to introduce touch el...
