Problems solved by technology
[0004] (1) Cause the display to increase in thickness and weight;
[0005] (2) The touch screen superimposed on the upper layer not only causes a decrease in light transmittance, a decrease in brightness, and a blurred display, but also the refraction effect generated by the touch screen is prone to defects such as what you touch is not what you get;
[0006] (3) Due to the increase in the process of attaching the two panels, the manufacturing process is complicated, resulting in an increase in production costs

[0083] The preparation process of the touch screen of this embodiment is briefly described as follows: first, a first metal film is deposited on the substrate, and a pattern including the first signal line is formed on the substrate through a patterning process using a common mask. Then a layer of piezoelectric film is deposited, and the pattern of the sensing electrode is formed on the first signal line through a patterning process using a common mask. The width of the sensing electrode is greater than the width of the first signal line below it. After that, a second metal film is deposited on the substrate, and a pattern including the second signal line is formed through a patterning process using a common mask. The second signal line is pressed on the sensing electrode, because the sensing electrode is wider than the first The width of a signal line is large, so the second signal line will not be connected to the first signal line. Similarly, in the patterning process of thi...

The present invention relates to a touch screen, a color film substrate and a manufacturing method thereof. The touch screen comprises a substrate, on which are formed a first signal line and a second signal line that intersect with each other. The first signal line and the second signal line are connected by an induction electrode, which generates electric charges when touched and compressed andgenerates the electric current signal in the first signal line and the second signal line to determine the position coordinates of a touch point. By the formation of the first signal line, the secondsignal line and the induction electrode on the substrate, the invention enables to determine the position coordinates of the touch point through the mechanism that piezoelectric thin film materials generate electric charges on the surface of the films when compressed. The touch screen of the present invention has the advantages of simple structure, low manufacturing cost, high precision, long service lifetime, etc.
Description
Technical field [0001] The invention relates to a touch device and a manufacturing method thereof, in particular to a touch screen, a color film substrate and a manufacturing method thereof. Background technique [0002] The existing touch screen has a variety of structural types, which are divided according to working principles, mainly including inductive, capacitive and resistive types. The main structure of the resistive touch screen is a resistive film that closely matches the surface of the display. The resistive film is used in conjunction with the display. If the coordinate position of the touch point on the display can be measured, it can be based on the display content or the corresponding coordinate point on the display. The graphic learns the intention of the toucher. [0003] Currently, liquid crystal displays with touch functions usually have a touch screen superimposed on the liquid crystal display. The actual use shows that the existing structure has the following...
