A kind of electrode layout of touch screen

Abstract

The invention relates to an electrode layout of a touch screen, and the electrodes include several X direction electrodes and several Y direction electrodes, and the X direction electrodes and Y The direction electrodes are composed of several electrode blocks, the electrode blocks are provided with a main body, and several branches are extended on the main body. X branch of the direction electrode and Y The branches of the direction electrodes intersect each other and form gaps, and the gaps are provided with diamond-shaped suspension blocks, and one side thereof is parallel to one side of the corresponding branches. The electrode layout of the touch screen according to the present invention not only overcomes the problem of viewing angle existing in the appearance, but also solves the problems of the touch screen. The electrode layout of the touch screen can improve the scanning speed and reporting rate while solving the suspension problem.

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. Currently, touch screens mainly include resistive touch screens, infrared touch screens, and capacitive touch screens, all of which obtain coordinates in different ways. The capacitive touch screen uses conductive materials such as fingers and stylus to approach or touch the touch screen to change the capacitance value of the touch screen. Wait until the position of the touch screen is touched, and perform the touch operation corresponding to the touched position. Since the capacitive touch screen has the characteristics of multi-finger touch, which can provide humanized operation, it has been fav...

AI Technical Summary

Problems solved by technology

For the electrode layout using a strip pattern, since the gaps formed by the strip pattern are filled with floating blocks, it has been proved by practice that this layout overcomes the instability of multi-finger touch detection, large power noise interference, and line drawing effect. However, when users use it, they find that because the liquid crystal molecules on the liquid crystal display are constantly flipping, there is a problem with the viewing angle of the electrodes on the touch screen, and the user can clearly see the floating blocks on the display, resulting in a certain appearance. Flaws; moreover, there is still a suspension problem to a certain extent with the above layout; and for the snowflake pattern, because the snowflake branch will cause the resistance to increase, the load delay time will become longer, which will affect the scanning speed and reporting rate. Therefore, this electrode layout also needs to be improved.
