Problems solved by technology

[0003] In addition, after a large number of tests, it was found that the traditional electrode structure such as the diamond structure has defects such as unstable multi-finger touch detection, large power noise interference, and poor line drawing effect. Therefore, it is necessary to provide users with a new type of single-touch Layer capacitive electrode layout structure to solve the above problems

Abstract

The invention discloses a single-deck capacitance electrode layout structure which comprises a substrate. A plurality of X electrodes and a plurality of Y electrodes are distributed on the substrate, wherein the X electrodes and the Y electrodes are parallel to one another and are arranged in the same direction, each X electrode comprises a main body and a plurality of branch bodies, each Y electrode comprises a main body and a plurality of branch bodies, each branch body extends from one side of the main body and then revolves back to the main body, and branch bodies of adjacent X electrode and Y electrode are arranged opposite to one another and are matched with one another. By means of the single-deck capacitance electrode layout structure, not only is a multi-finger touch function achieved, but also the cost of a touch screen is lowered. Meanwhile, coupling signals are added among electrodes, therefore, the signal strength of the touch screen is strong, the linearity of the touch screen is high, scanning speed is improved obviously, and at the same time signal resolution in a suspended state is improved.

Description

technical field [0001] The invention relates to the field of capacitive electrode layout structure, in particular to a single-layer capacitive electrode layout structure. Background technique [0002] A traditional capacitive touch screen usually includes electrodes in two directions, which are X-direction electrodes and Y-direction electrodes respectively. An insulating layer is placed between the X-direction electrodes and Y-direction electrodes, which are all laid on the substrate. The mutual conduction between them, the bridging point is set on the base, if the electrode blocks are connected to each other in one direction, then the electrode blocks are connected to each other by bridging in the other direction. Although the above method realizes the touch detection action, the double-layer capacitive electrode layout structure is not only complicated in process, but also easily damaged at the bridge, resulting in low product yield and high cost. In order to overcome the...
