Problems solved by technology

[0003] However, the multiple configurations between the touch panel and the display panel will consume a lot of production materials during manufacture, and each layer structure of the touch panel is traditionally produced separately first, and then stacked and laminated sequentially. One, so its assembly process is more complicated, and waste of man-hours, easy to produce defective products
Moreover, the problem of excessively increasing the stepped thickness formed by stacking is not conducive to the thin design of electronic products, so it needs to be improved urgently

Embodiment Construction

[0029] Embodiments of the touch panel according to the present invention will be described below with reference to related drawings. For ease of understanding, the same components in the following embodiments are marked with the same symbols for illustration.

[0030] see figure 1 , which is a cross-sectional view of the first embodiment of the touch panel of the present invention. Such as figure 1 As shown, the touch panel includes: a substrate 10, a shielding layer 20, a sensing circuit layer 40 and an isolation layer 30. The substrate 10 can be glass, for example, which has a top surface and a bottom surface respectively. The shielding layer 20 Formed on the periphery of the bottom surface of the substrate 10, it is a "black matrix" (Black Matrix) or other coating with a shielding effect, which can be a metal layer or an organic layer. In addition, the sensing circuit layer 40 is arranged on the substrate 10 and is connected with the shielding layer 20 Located on the same...

Abstract

A touch panel, which contains a substrate, a mask layer, a sensing circuit layer and a barrier layer, is disclosed. The mask layer is disposed around the bottom surface of the substrate. The sensing circuit layer is located on the same side of the substrate with the mask layer, and the surrounding area of the sensing circuit layer is shielded by the mask layer. In addition, the area of the sensing circuit layer exposed from the mask layer is defined as a sensing region. Furthermore, the barrier layer is disposed between the substrate and the sensing circuit layer and between the mask layer and the sensing circuit layer. Concurrently, the barrier layer further provides separation between the mask layer and the sensing circuit layer. The barrier layer has a transparent appearance. Particularly, the barrier layer is provided for changing optical refraction and harmonizing optical reflection index and transmittance.

Description

technical field [0001] The invention relates to a touch panel, especially a touch panel with an isolation layer between the shielding layer and the sensing circuit layer. Background technique [0002] The current touch panel is quite popular in use. Users only need to use objects such as fingers or stylus to click according to the images and text displayed on the screen, and then press the touch panel to input Or operation, very convenient to use. [0003] However, the multiple configurations between the touch panel and the display panel will consume a lot of production materials during manufacture, and each layer structure of the touch panel is traditionally produced separately first, and then stacked and laminated sequentially. One, so its assembly process is more complicated, and waste man-hours, easy to produce defective products. Moreover, the problem of excessively increasing the thickness of the steps formed by stacking is not conducive to the thinning design of ele...
