Abstract

The invention discloses a touch substrate, a manufacturing method thereof and a touch display device and belongs to the technical field of touch control. The touch substrate comprises a touch area and a peripheral area which are located on the substrate. The peripheral area comprises at least one signal line and at least one shielding line, and the shielding line is used for shielding interference of the signal line on the capacitance of the touch area. By means of the touch substrate, interference of the signal line on the touch area can be shielded, and the problem that the capacitance of a touch substrate is not uniform in distribution is alleviated.

Description

technical field [0001] The present invention relates to the field of display and touch technology, in particular to a touch substrate, a manufacturing method thereof, and a touch display device. Background technique [0002] With the rapid development of smart phones and tablet computers, touch screens have been widely used in daily life. At present, the most popular is the capacitive touch screen. When the finger touches the screen, the touch screen will calculate the position of the finger through the current generated by the capacitance change. [0003] Generally, a touch substrate includes a touch area and a peripheral area. Among them, the touch area is the area where the user can see the image and touch it, and the peripheral area includes a plurality of signal lines for providing control signals for the touch area, that is, one end of the signal line is connected to the touch area, and the other end Connect various drive control signals. [0004] With the developme...
