Array substrate and manufacturing method thereof, touch control panel and touch control device

Abstract

The embodiment of the invention provides an array substrate and a manufacturing method thereof, a touch control panel and a touch control device. The array substrate comprises an underlying substrate; a gate metal layer; a virtual layer which is arranged at one side, which is away from the underlying substrate, of the gate metal layer, wherein a gate insulating layer is arranged between the virtual layer and the gate metal layer; and a source-drain metal layer which is arranged at one side, which is away from the underlying substrate, of the virtual layer, wherein the virtual layer is adjacent to and contacted with the source-drain metal layer. The source-drain metal layer comprises multiple signal lines which include multiple touch control leads and multiple data lines. The virtual layer comprises multiple virtual leads which have the same shape with that of the multiple signal lines. The orthographic projection of the multiple signal lines in the source-drain metal layer is completely overlapped with the orthographic projection of the multiple virtual leads in the virtual layer in a direction perpendicular to the plane of the underlying substrate. Therefore, the problems of influencing the display effect and the touch control sensitivity of the touch control panel caused by high resistance of the touch control signal lines can be solved to a certain extent by the technical scheme.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of touch display, in particular to an array substrate and a manufacturing method thereof, a touch panel and a touch device. [0003] 【Background technique】 [0004] Currently, touch panels generally transmit touch signals through touch signal lines. In the prior art, the touch signal line and the data line are generally located in the same metal layer, and the touch signal line and the data line are generally arranged in the source-drain metal layer, and the extension direction of the data line is the same as the extension direction of the touch signal line. The same direction. [0005] However, in order not to reduce the aperture ratio of the touch panel as much as possible, the touch signal line should be as narrow as possible. The longer the distance between the control electrode and the IC, the greater the resistance of the touch signal line. In this way, it is easy to cause a large del...
