Embodiment Construction

[0028] see figure 1 , which is a schematic diagram of the first embodiment of the touch panel 1 of the present invention. The touch panel 1 includes a transparent substrate 12 , a protective substrate 15 and an optical glue 13 for laminating the transparent substrate 12 and the protective substrate 15 . The transparent substrate 12 is provided with a touch sensing layer 124 and a conductive circuit 122 electrically connected to the touch sensing layer 124 .

[0029] An ink layer 14 is disposed around the protection substrate 15 , and the ink layer 14 is used to shield the conductive circuit 122 . The ink layer 14 includes at least two layers of ink, which are stacked. In this embodiment, the ink layer 14 is two layers. The first layer of ink 142 is disposed on the protective substrate 15 and defines the visible area 16 of the touch panel 1 . The second layer of ink 145 is disposed on the first layer of ink 142, and the width of the first layer of ink 142 is greater than th...

Abstract

The invention relates to a touch panel and a protection substrate used for the touch panel. The touch panel comprises a touch control inducing layer and the protection substrate, wherein an ink layer is arranged at the periphery of the protection substrate; the ink layer comprises at least two layers of ink arranged in a laminating manner; in the two adjacent layers of ink, the width of the ink close to the protection substrate is greater than that of the ink far away from the protection substrate, so that a step is formed; the first layer of ink is close to the protection substrate and defines a visual area of the touch panel; except the first layer of ink, a notch retracted from the visual area to the edge of the protection substrate is formed in at least one of the other layers of the ink layer; and the touch control inducing layer corresponds to the visual area.

Description

technical field [0001] The invention relates to a touch panel and a protective substrate used for the touch panel. Background technique [0002] With the rapid development of science and technology, touch technology, as the most simple, convenient and natural way of human-computer interaction, has received global attention and has been widely used in various industries. [0003] In the current touch panel, the traditional double-layer substrate structure is a touch substrate and a protection substrate, and the touch substrate and the protection substrate of the touch panel are generally pasted and fixed by optical glue. The touch-sensitive substrate is provided with a touch-sensitive layer and a conductive circuit electrically connected with the touch-sensitive layer. Opaque ink is provided on the periphery of the protective substrate to block the conductive lines generally made of opaque metallic silver wires. In order to ensure the shading effect of the ink, the ink need...
