Problems solved by technology

As far as the light-curing material is concerned, since the decorative layer and the circuit will block light, no matter whether it is illuminated from the side of the component substrate or the side of the decorative substrate, it is difficult for the light-curing material located in the peripheral area to receive sufficient light beams, so that the component substrate and the decorative substrate The corresponding peripheral areas cannot be tightly bonded together, which will adversely affect the reliability of the touch panel

Abstract

The present invention provides a touch panel comprising a first substrate, a decorative layer, a second substrate, a photo-curable adhesive layer, a touch element, a plurality of light-transmitting protruding structures, and a plurality of first wires. The first substrate has an active region and a peripheral region connecting the active region. The decorative layer is disposed on the first substrate, exposing the active area and covering the peripheral zone. The second substrate is opposed to the first substrate. The photo-curable adhesive layer engages the first substrate and the second substrate. The touch element is disposed on the second substrate and in the active region. The light-transmitting protrusion structure is provided on the second substrate and is located in the peripheral region. The first wire is disposed on the light transmissive projection structure, located in the peripheral region and electrically connected to the touch element. The touch panel of the present invention helps to enhance the adhesion of the photo-curable adhesive layer in the peripheral region.

Description

technical field [0001] The present invention relates to a panel, and in particular to a touch panel. Background technique [0002] Generally speaking, lines for transmitting signals are disposed in the peripheral area of ​​the touch panel. In order to prevent the circuit from being exposed and affect the visual effect of the touch panel, a decorative substrate is usually pasted outside the component substrate (including touch components and circuits) of the touch panel to shield the circuits in the peripheral area through the decorative layer of the decorative substrate. . [0003] In the prior art, the component substrate and the decorative substrate are bonded together mainly through a photocurable adhesive layer or a thermally curable adhesive layer. As far as the light-curing material is concerned, since the decorative layer and the circuit will block light, no matter whether it is illuminated from the side of the component substrate or the side of the decorative subst...
