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

Abstract

The invention relates to electrode layout for a touch screen. The electrode comprises a plurality of X-direction electrodes and a plurality of Y-direction electrode which respectively consist of a plurality of electrode blocks, wherein each electrode block is gourd-shaped and is a centrosymmetric octagon; the two adjacent electrode blocks in the X direction and the two electrode blocks in the Y direction form a gap; and a suspending block is arranged in each gap. The electrode layout for the touch screen solves the visual angle problem in the appearance, also solves the suspension problem of the touch screen, and increases the scanning speed and the point reporting ratio at the same time.

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...
