Abstract

A touch panel having a light transmitting area and a light shielding area adjacent to the light transmitting area is provided. The touch panel includes a cover plate, a first decoration layer, a touch-sensing element and a metal conductive layer. The first decoration layer is disposed on the cover plate and located in the light shielding area. The first decoration layer has at least one hollow area. The touch-sensing element is disposed on the cover plate and at least located in the light transmitting area. The metal conductive layer is disposed on the first decoration layer, located in the light shielding area and surrounds the touch-sensing element. A portion of the metal conductive layer surrounds the hollow area.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with improved appearance and visual effects. Background technique [0002] Generally speaking, the touch panel must be installed on the surface of the electronic product to facilitate the user to perform touch input and operation, or combined with the surface of the display panel to provide touch and display functions. However, in order to cover the position of the transmission line and the layout of the circuit, the boarder of the touch panel is usually provided with a dark color, such as a black light-shielding material. As a result, the borders of electronic products are often black, which cannot meet the needs of users for the appearance of products. [0003] Furthermore, in existing electronic devices, logos of corporate brands or product models are often installed on the electronic devices themselves as a representation of corporate image or product features.
