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 X The direction electrode block is in the shape of a wavy line like a cross, the Y The direction electrode block is in the shape of a partial wavy rhombus, and the wavy parts of the two electrode blocks mesh with each other to form a gap in the area between them, and a suspension block is arranged in the gap. 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 suspension problem has been solved, and the scanning speed and reporting rate have also been improved.

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. As for the snowflake-like pattern, because the snowflake-like branch will lead to increased resistance and longer load delay time, which will affect the scan speed and reporting rate, so this electrode layout also needs to be improved
