Problems solved by technology

Although the above-mentioned electrode layout structure is simple, when the user uses the touch screen, there will be a problem of floating, that is, if the user stands on the ground and directly operates the touch screen on the palm of the hand, the sensitivity of the touch screen is better because the human body is directly grounded; The touch screen is used in the car. Since the user cannot be directly grounded at this time, the sensitivity of the touch screen will decrease.
Therefore, if the use environment of the touch screen is changed, it may cause the suspension problem of the touch screen

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Please refer to figure 1 and figure 2 As shown, the present invention relates to an electrode layout of a touch screen. The touch screen 1 mainly includes a substrate 10 and an electrode layer 11 disposed on the substrate 10. The electrode layer 11 is provided with a cover plate 12. On the cover plate 12, A liquid crystal display 13 is provided. The electrode layer 11 is composed of a number of electrodes 110 in a rhombus shape, and they are respectively arranged in a cross direction along the longitudinal direction and the lateral direction of the substrate 10. The electrode layer 11 can be arranged on the upper and lower sides of the substrate 10 respectively. It can be arranged on the same side of the substrate 10 , that is, the upper side. In this case, an insulating layer needs to be provided between the two electrode layers 11 . No matt...

Abstract

The invention relates to an electrode layout of a touch screen. The touch screen mainly comprises a base plate and an electrode layer, wherein the electrode layer is arranged on the base plate; a cover plate is arranged on the electrode layer; a liquid crystal display screen is arranged on the cover plate; the electrode layer is formed by multiple electrodes in rhombic combinative shapes; further, the electrodes are crosswise arrayed in the longitudinal direction and the transverse direction of the base plate respectively; the electrodes are partially in hollow shapes. The electrode layout provided by the invention not only solves a suspension problem of the touch screen, but also greatly improves the linearity of the touch screen; moreover, the compatibility between the electrode layer and the liquid crystal display screen is also enhanced.

Description

technical field [0001] The invention relates to an electrode layout of a touch screen, in particular to an electrode layout of a capacitive touch screen. Background technique [0002] With the development of science and technology, touch screens have gradually replaced mechanical button panels as new operating interfaces for electronic devices such as mobile phones and notebooks. Touch screens include resistive touch screens, infrared touch screens, and capacitive touch screens. They obtain coordinates in different ways, and capacitive touch screens are used in more and more products because of their better light transmittance, clarity, and reliability. . [0003] An important component structure of the capacitive touch screen is the electrode layout. The electrode layout of the capacitive touch screen commonly used now includes the X-axis sensing electrode and the Y-axis sensing electrode. Rows and several columns are arranged sequentially, and one column of X-axis sensin...
