Problems solved by technology

[0006] Whether the above-mentioned touch screen utilizes the resistance effect, capacitive effect, or near-field detection principle, it is necessary to detect the change of the surface state of the touch screen by applying an external detection signal; the touch screen must rely on the external detection signal to obtain correct touch information, which will It is easy to be interfered by the outside world (such as external light, electromagnetic interference, etc.) and cause contact misjudgment

Embodiment 1

[0029] like figure 1 and figure 2 As shown, the touch screen provided in the embodiment of the present invention includes a first substrate 101 and a second substrate 102 oppositely arranged, wherein at least two strip-shaped transparent wires arranged in parallel are formed on the first substrate 101 103 (take horizontal arrangement as an example in the figure), at least two piezoelectric elements 104 are arranged on the transparent wire 103; .

[0030] In the embodiment of the present invention, the transparent wires may be made of ITO (Indium Tin Oxides, nanometer indium tin oxide) material, and the arrangement direction of the transparent wires 103 may be but not limited to figure 1 The horizontal arrangement shown in , can also be arranged vertically.

[0031] In addition, an embodiment of the present invention also provides a touch-screen liquid crystal display completed by using the above-mentioned touch screen; image 3 As shown, the touch screen liquid crystal di...

Embodiment 2

[0035] The touch screen provided in the embodiment of the present invention will be described in detail below with a specific embodiment.

[0036] combine figure 1 and figure 2 As shown, the touch screen provided in the embodiment of the present invention includes a first substrate 101 and a second substrate 102 oppositely arranged, wherein at least two strip-shaped transparent wires arranged in parallel are formed on the first substrate 101 103 (take horizontal arrangement as an example in the figure), at least two piezoelectric elements 104 are arranged on the transparent wire 103; , the electrical signal detection device 105 is used to measure the current intensity of the current it receives.

[0037] In the embodiment of the present invention, the arrangement direction of the transparent wires 103 may be as follows figure 1 The horizontal arrangement shown in , can also be arranged vertically. Moreover, both the first substrate 101 and the second substrate 102 may be,...

Embodiment 3

[0063] In this embodiment, a touch screen liquid crystal display completed by using the touch screen in Embodiment 2 will also be provided.

[0064] combine image 3 As shown, the touch screen liquid crystal display includes a touch screen 100 and a liquid crystal display panel 300; wherein, the touch screen 100 is the touch screen described in Embodiment 2, which will not be repeated here; and the liquid crystal display panel 300 includes a relatively set A color filter substrate 301 and an array substrate 302, and liquid crystal 303 is filled between the color filter substrate 301 and the array substrate 302;

Abstract

The embodiment of the invention discloses a touch screen and a touch screen liquid crystal display, which relate to the field of a touch screen and are used for strengthening the resistance to the external interference and saving energy sources. The touch screen disclosed by the embodiment of the invention comprises a first base plate and a second base plate which are oppositely arranged; at least two strip transparent wires which are ranked in parallel are formed on the first base plate; at least two piezoelectric elements are arranged on the transparent wires; and electric signal detection devices are arranged at the two ends of each transparent wire. The scheme disclosed by the embodiment of the invention is suitable for any display equipment which comprises the touch screen disclosed by the embodiment of the invention.

Description

technical field [0001] The invention relates to a touch screen, in particular to a touch screen made of piezoelectric material and a liquid crystal display of the touch screen. Background technique [0002] As a special computer peripheral, touch screen is currently the simplest, most convenient and natural way of human-computer interaction; it endows multimedia with a new look and is an attractive new multimedia interactive device. [0003] Currently, touch screens mainly include the following types: resistive touch screens, infrared touch screens, capacitive touch screens, surface acoustic wave touch screens and near-field imaging touch screens. [0004] No matter what type of touch screen, it generally includes two parts: a touch screen controller and a touch detection device. Among them, the touch detection device is generally installed on the front of the display, and its main function is to detect the user's touch position by applying an external detection signal (suc...
