Problems solved by technology

[0004] However, in the prior art, each touch signal line is arranged through the display area of ​​the display panel, and what actually functions is only the connection between the driving chip and the via hole used to connect the touch signal line and the corresponding touch electrode. Part, the remaining part of the wiring is not used, but the space occupied by the remaining part can no longer be used to set up other components, resulting in a waste of space

Abstract

The invention discloses a touch control display device comprising a display area and a non-display area; the display area comprises a scanning line layer, a signal line layer and a touch control electrode layer; the scanning line layer, the signal line layer and the touch control electrode layer are spaced by insulating layers respectively; the scanning line layer comprises multiple scanning lines; the signal line layer comprises multiple signal lines; the multiple signal lines and the multiple scanning lines are staggeredly arranged; at least one grid signal line is electrically connected with one scanning line through a first through hole; at least one touch control signal line is electrically connected with a touch control electrode block through a second through hole. By means of the technology scheme provided by the embodiment, touch control signal lines and grid signal lines are set at the same layer, and the space, where the part of the touch control signal lines is ineffectively utilized, is cleverly utilized for installing grid signal lines to avoid the waste of space.

Description

technical field [0001] The present invention relates to the field of touch display, in particular to a touch display device. Background technique [0002] The touch display device that integrates the touch function inside the display panel does not need to set up a special space for the touch module, which expands the configurable area of ​​the screen, thereby meeting the needs of users for portable electronic products with simple operation, small size and large screen size. Gradually become a mainstream display device. [0003] The touch display device includes a touch display panel. According to different working principles, the touch display panel is divided into a self-capacitive touch display panel and a mutual capacitance touch display panel. For a self-capacitive touch display panel, each touch electrode block needs to receive a touch signal generated by a driving chip through a touch signal line electrically connected to it. In the prior art, a layer of touch signa...
