Abstract

The invention relates to a touch screen, a color film base plate and a manufacture method thereof. The touch screen comprises a base plate, wherein a plurality of first signal lines and second signal lines for forming a plurality of touch sensing areas are arranged on the base plate; the first signal lines are connected with a first piezoelectric switch; the second signal lines are connected with a second piezoelectric switch; and the first piezoelectric switch and the second piezoelectric switch are used for conducting when the touch sensing areas are in touch and are applied with voltage and transferring a voltage signal respectively by the first signal lines and the second signal lines for confirming position coordinates of the touch sensing areas in touch. The invention utilizes the principle that charge is formed on the surface of a film when a piezoelectric film is applied with voltage, adopts structural ways of the signal lines and the piezoelectric switches and has the advantages of simple structure, low cost, high precision, long service life, and the like.

Description

technical field [0001] The invention relates to a touch device and a manufacturing method thereof, in particular to a touch screen, a color filter substrate and a manufacturing method thereof. Background technique [0002] Existing touch screens have various structure types, which are classified according to working principles, mainly including inductive, capacitive and resistive types, among which the resistive touch screen is controlled by pressure sensing. 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 displayed according to the display content of the corresponding coordinate point on the display or Graphics learn the touch's intent. At present, the resistive touch screens applied to liquid crystal displays in the prior art mainly include two types: four-w...

AI Technical Summary

Problems solved by technology

Although the five-wire resistive touch screen improves the service life by using a nickel-gold conductive layer with good ductility and low resistivity, the structure has defects such as complex structure and high cost.

In addition, due to process limitations, the uneven thickness of the nickel-gold conductive layer will cause uneven distribution of the voltage field, and there will be defects such as reduced accuracy caused by linear distortion.
