Problems solved by technology

However, this method will inevitably generate impedance, which will affect the driving ability; moreover, no matter how the electrode group is arranged on the substrate, the process of using two-layer electrode groups is definitely more complicated than the process of only one layer of electrode groups

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Please refer to figure 2 and image 3 In the structure diagram of the capacitive sensor shown, the sensor 1 includes a substrate 10 and a layer of electrode group 11 , wherein the electrode group 11 is arranged on one side of the substrate 10 , and the electrode group 11 is composed of several diamond-shaped blocks 12 .

[0014] Please refer again figure 2 As shown, the rhombic electrode blocks 12 are arranged vertically and rowwise respectively. When the rhombus blocks 12 are arranged vertically, each rhombic electrode block 12 in each column is sequentially connected; when the rhombic blocks 12 are arranged horizontally, in order to avoid electrode The mutual conduction between them, so at this time can not be sequentially connected on the above-mentioned side, you can choose to open a groove 13 between the electrodes arranged horizontally ...

Abstract

The invention relates to a capacitance sensor, which comprises a base plate and a layer of electrode groups, wherein the electrode groups are arranged on one side of the base plate; electrodes in two directions are arranged on the layer of electrode groups; grooves are formed between the electrodes in one direction; and deformable conductors are filled in the grooves. In the invention, mutual conduction of the electrode groups in two directions can be realized by only using one layer of electrode groups, and the capacitance sensor is simpler in process and low in impedance, so the driving capacity of the capacitance sensor is improved.

Description

technical field [0001] The invention relates to a sensor, in particular to a capacitance sensor. Background technique [0002] The so-called capacitive sensor generally refers to a device or device that uses the principle of capacitance to transmit signals in the X and Y directions. It can be an ITO (indium tin oxide) layer, PCB board, keyboard or touch screen, etc., usually by human fingers or Stylus actuation. Existing capacitive sensors usually have two layers of electrode sets, please refer to figure 1 As shown, one layer of electrode groups is used as the X direction, and the other layer of electrode groups is used as the Y direction, which are respectively arranged on both sides or one side of the glass base. When the two layers of electrode groups are arranged on both sides of the glass base, in order to prevent the two layers of electrode groups from being connected to each other, it is necessary to punch holes in the glass substrate so that one layer of electrode ...
