Problems solved by technology

[0007] However, it is known that this kind of touch panel is manufactured by layering the sensing pads, so the sensing pads of different layers are likely to have different property changes due to different subsequent manufacturing processes, such as differences in light transmittance
Moreover, since the sensing pads are arranged in different layers, the overall light transmission uniformity of the touch panel will also be affected by the position of the sensing pads, or the optical path difference of the reflected light.
All of the above factors will cause the user to have a problem of color difference when viewing the touch panel
[0008] On the other hand, when the touch panel is combined with the display device, it is unavoidable that the user will notice the sensing pads on the touch panel when watching the screen carefully, especially when the sensing pads are configured and the sensing pads are not configured. region, which shows a more pronounced difference

Embodiment Construction

[0041] 2A to 2C illustrate a touch panel according to an embodiment of the present invention, wherein FIG. 2A is a perspective view of the touch panel, FIG. 2B is a perspective view of the touch panel, and FIG. 2C is a perspective view of the touch panel Sectional view. For clarity, FIGS. 2A and 2B only show the structure of the contact pads of the touch panel, while omitting other possible film layers. FIG. 2C shows the substrate and possible film layers such as dielectric layers, so as to For example.

[0042] As shown in FIGS. 2A-2C , the touch panel 200 of this embodiment has a double-layer sensing pad structure, including a substrate 210, a first sensing series 220, a second sensing series 230, a plurality of first The pseudo-sensing pad 242 and a plurality of second pseudo-sensing pads 252, wherein the number of the first sensing series 220 and the second sensing series 230 can be one or more, depending on the actual situation (such as a touch panel 200 size) depends. ...

Abstract

A kind of touch control panel and its fabrication method, it can have double layer sensing pas structure or single layer sensing pas structure. In this double layer sensing pas structure, the sensing pas of each lay has the corresponding plan sensing pas in the other layer to compensate the difference of the transmittance of light. In the single layer sensing pas structure, the sensing pas are in the same plane, so it can over come the problem of chromatic aberration, improve the visual effect of the touch control panel.

Description

【Technical field】 [0001] The present invention relates to a touch panel and a manufacturing method thereof, in particular to a touch panel capable of providing better visual effects and a manufacturing method thereof. 【Background technique】 [0002] With the development of the industry, digital tools such as mobile phones, personal digital assistants, notebook computers and tablet computers are all developing in a more convenient, multi-functional and beautiful direction. .
