Embodiment Construction

[0021] see figure 1 , which is a schematic cross-sectional structure diagram of the first embodiment of the touch screen of the present invention. The touch screen 2 includes a first substrate 21 and a second substrate 22 oppositely disposed. The first substrate 21 is generally made of elastic transparent material, and the second substrate 22 is made of rigid transparent material to bear a certain pressure. In this embodiment, the first substrate 21 is a polyester film, and the second substrate 22 is a glass substrate. A first conductive layer 23 is disposed on a surface of the first substrate 21 opposite to the second substrate 22 . A second conductive layer 24 is disposed on a surface of the second substrate 22 opposite to the first substrate 21 . An adhesive layer 25 is disposed at the edge between the first substrate 21 and the second substrate 22 to bond the first substrate 21 and the second substrate 22 together. The distance between the first conductive layer 23 and...

Abstract

The invention provides a touch screen, which comprises a first substrate and a second substrate which are arranged oppositely, as well as a first transparent conductive layer arranged on the inner surface of the first substrate and a second transparent conductive layer arranged on the inner surface of the second substrate. The resistivity of the second transparent conductive layer along a first direction is larger than that along a second direction. The invention further provides a driving method of the touch screen.

Description

technical field [0001] The invention relates to a touch screen and a driving method of the touch screen. Background technique [0002] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices equipped with touch screens have gradually increased. Such an electronic device allows the user to directly touch the touch screen with hands or other objects to input information to the electronic device, which can reduce or eliminate the user's dependence on other input devices (such as keyboards, mice, remote controls, etc.), which is convenient for users. operation. [0003] The touch screens in the prior art mainly include resistive, capacitive, infrared and surface acoustic wave types. Generally, a touch screen can only input one touch action at a time during use. Recently, a touch screen that can simultaneously input two or more points has become a popular t...
