Problems solved by technology

[0006] Based on the above, the existing touch-sensitive color filter needs to form the through hole in the first dielectric layer through the photomask process, so the process is relatively complicated, and the process yield cannot be guaranteed.
In addition, because the X electrodes and Y electrodes of the touch-sensitive color filter are usually a coplanar single-layer design (compared to the non-coplanar X electrodes and Y electrodes, called double layers), the configuration and number of electrodes are easily limited. , so that the touch resolution cannot be further improved
[0007] In other words, most of the existing touch panel manufacturing has the problems of complex process and limited resolution. Therefore, how to improve the process of touch panel and further enhance the touch resolution is an urgent need for touch panel manufacturing technology. a major topic of
