Abstract

The invention relates to a capacitance type touch circuit graphic structure and a preparation method thereof. The method comprises the following steps of: forming at least one group of first electrode blocks, at least one group of first wires and at least one group of second electrode blocks on a substrate at one time, wherein each group of first electrode blocks comprises at least two first electrode blocks which are arranged at intervals along a first axial direction; each group of first wires is arranged among the adjacent first electrode blocks in the same first electrode block group; and each group of second electrode blocks comprises at least two second electrode blocks which are arranged at intervals along a second axial direction; forming an insulating layer on the substrate so as to cover at least one part of the first wires; and forming at least one group of second wires on the substrate, wherein each group of second wires is arranged among the adjacent second electrode blocks in the same second electrode block group. The invention has the advantages that: the plurality of first axial electrode blocks and the plurality of second axial electrode blocks can be formed in processing at one time, so that the times of the processing which is required for arranging the touch circuit graphic structure is reduced.

[0005] In addition, the method for making the above-mentioned traditional capacitive touch circuit graphic structure is to form a plurality of electrode blocks of the first group of capacitive sensing layers in the first processing, and to form a peripheral circuit in the second processing, and the above-mentioned A plurality of electrode blocks of the first group of capacitive sensing layers are connected, a whole-surface insulating layer is formed by the third processing, a plurality of electrode blocks of the second group of capacitive sensing layers are formed by the fourth processing, and a fifth is processed. Secondary processing forms another peripheral circuit, and is connected with the plurality of electrode blocks of the second group of capacitance sensing layers; but its disadvantage is that the plurality of electrode blocks of the above two groups of capacitance sensing layers, the insulating layer and the The surrounding lines must be processed five times, resulting in more cumbersome processing problems, and the wires connecting the multiple electrode blocks are also made of indium tin oxide, which makes it difficult to effectively connect the impedance between each electrode block and the surrounding lines. It is difficult to improve the signal transmission sensitivity between each electrode block and the surrounding lines, so it needs to be improved
