Problems solved by technology

Screen printing technology is generally limited to flat printing, but in practical applications, the edge of the protective cover may be set as a curved surface, so it is necessary to avoid the curved surface to set the wiring area, resulting in low utilization of the surface of the protective cover, which is not conducive to the miniaturization of the touch panel

Embodiment Construction

[0020] see figure 1 , The touch panel 10 according to the preferred embodiment of the present invention includes a display panel 12 and a protective cover 14 covering the display panel 12 . The protective cover 14 includes a substrate 142 , a sensing layer 144 and at least one wire 146 . The substrate 142 includes a touch surface 1421 opposite to the display panel 12 and an assembly surface 1422 opposite to the touch surface. The assembly surface 1422 includes a sensing area 1423 and a wiring area 1424 surrounding the sensing area. . The wiring area 1424 is a curved surface. The sensing layer 144 is formed in the sensing region 1423 for sensing a touch action applied on the touch surface 1421 . The at least one wire 146 is formed in the wiring area 1424 and is electrically connected with the sensing layer 144 .

[0021] That is to say, the protective cover 14 of the present invention directly arranges the wiring area 1424 on the curved surface instead of avoiding the curve...

Abstract

The invention provides a touch panel, which comprises a display panel and a protective cover covering the former, wherein the protective cover comprises a baseplate, a sensing layer and at least one conducting wire; the baseplate comprises a touch surface back to the display panel, and an assembling surface back to the touch surface; the assembling surface comprises a sensing area and a wiring area surrounding the sensing area, and the wiring area adopts a curved surface; the sensing layer is formed in the sensing area and used for sensing the touch action exerted on the touch surface; the at least one conducting wire is arranged in the wiring area and is electrically connected with the sensing layer. Therefore, the protective cover is improved in surface utilization ratio, as the wiring area is directly arranged on the curved surface, rather than avoiding the curved surface. Besides, given the same size, the baseplate adopting the curved surface can increase the surface area, and as a result, the surface utilization ratio of the protective cover is further improved.

Description

technical field [0001] The invention relates to touch panel technology, in particular to a protective cover with a curved surface and a touch panel with the protective cover. Background technique [0002] In an existing touch panel, the touch sensing layer is directly formed on the protective cover without using a separate touch panel, which can reduce the thickness of the touch panel, so it is popular. The touch sensing layer generally includes a touch area and a wiring area, the touch area is used to sense touch, and the wiring area is arranged around the touch area, including the process of making the touch area and processing the sensing signal by using screen printing technology wires for electrical connection. In this way, the processor can receive the sensing signal, and realize the processing and response of the touch signal. Screen printing technology is generally limited to flat printing, but in practical applications, the edge of the protective cover may be set ...
