Problems solved by technology

However, in the process of separating the carrier substrate 10, since the thickness of the release layer 12 and the support carrier 14 itself is relatively thin and the touch structure 16 is mainly distributed in the central area of ​​the support carrier 14, the edge region of the support carrier 14 is easy to curl when separated, Moreover, the touch structure in the edge area is prone to fall off or damage, which will affect the yield of the monolithic glass touch panel

Abstract

The invention provides a manufacturing method of a single-glass touchpad. The manufacturing method of the single-glass touchpad comprises the steps that firstly, a substrate is provided; secondly, a bearing layer is formed on the substrate; thirdly, a patterned conductive layer is formed on the bearing layer, and the patterned conductive layer comprises a sensing electrode and an auxiliary electrode located at the outer side of the sensing electrode; fourthly, a signal conductor is formed and electrically connected with the sensing electrode, the signal conductor is gathered in least one bonding region, the bonding region or bonding regions are located in at least one outer side edge of the sensing electrode; fifthly, a covering plate is attached to the patterned conductive layer, and the substrate is removed from the bearing layer. By means of the manufacturing method of the single-glass touchpad, the problems that an edge area of the bearing layer curls easily and components at the edge area fall off or are damaged easily when the substrate is removed are relieved.

Description

technical field [0001] The present invention relates to touch technology, and in particular to a single glass touch panel and a manufacturing method thereof. Background technique [0002] In recent years, with the prevalence of mobile devices with touch functions such as smart phones and tablet computers, issues such as reducing the production cost of touch panels and making thinner and lighter touch panels have become increasingly important. Monolithic glass touch panels is one of the structures that can meet this requirement. [0003] Please refer to FIG. 1 , which illustrates a conventional technology for manufacturing a single-piece glass touch panel. Firstly, a release layer 12 is formed on the carrier substrate 10, and a support with a larger area is formed above it. Carrier 14, and after completing the manufacturing process of the touch structure 16 on the support carrier, it is then cut along the edges C and C' of the release layer 12, and the carrier substrate 10 i...
