Problems solved by technology
However, whether it is an external-mounted touch panel or an integrated touch panel, because the touch electrode series are mostly made of transparent conductive oxides, and the transmittance and refraction of transparent conductive oxides to light The refractive index is different from that of the substrate. Therefore, the outline of the touch electrode series on the substrate is easy to be observed by the user, resulting in poor visual perception.
In addition, it is even possible that the overall display quality of the touch display panel may be degraded because the outline of the sensing electrode pattern is too obvious.

Abstract
The invention discloses a touch baseplate which comprises a baseplate, first touch electrode series and second touch electrode series. The first touch electrode series are configured on the baseplate and extend along a first direction, and each first touch electrode series comprises a plurality of first touch pads which are electrically connected with each other. The second touch electrode series are configured on the baseplate and extend along a second direction, each second touch electrode series comprises a plurality of second touch pads which are electrically connected with each other, and the first direction is different from the second direction. In addition, the space between each first touch pad and the adjacent second touch pad ranges from 10 microns to 60 microns. The invention controls the thickness of the touch pads, or controls the space between the adjacent touch pads, so that a user can not easily observe the contour of the touch pads when using the touch baseplate.
Description
technical field [0001] The present invention relates to a touch sensing panel, and in particular to a touch sensing panel with good visual appearance. Background technique [0002] According to different sensing principles, touch panels can be classified into resistive touch substrates, capacitive touch substrates, optical touch substrates, acoustic wave touch substrates, and electromagnetic touch substrates. Since the capacitive touch substrate has the advantages of fast response time, high sensitivity, good reliability and high durability, the capacitive touch substrate has been widely used at present. [0003] According to the way of composition, the capacitive touch substrate can be divided into two types: external mount type and integrated type (built-in type). Although the integrated capacitive touch substrate has the advantages of easy design of the touch electrode pattern and simple manufacturing process. However, whether it is an external-mounted touch panel or an...
