Abstract

The invention discloses a touch substrate, a manufacturing method thereof, and a touch display device, belonging to the field of touch technology. The touch substrate includes: a touch area and a peripheral area located on the substrate; wherein the peripheral area includes at least one signal wiring and at least one shielding line, and the shielding line is used to shield the signal wiring pair The interference of the capacitance of the touch area. The invention can shield the interference of the signal wiring to the touch area, and improve the problem of uneven capacitance distribution of the touch substrate.

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...
