Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 3 and 4, the present invention provides a display panel, including,

a substrate 10; a conductive layer 20 at least partially covering the substrate 10; a polarizer 30 at least partially covering the conductive layer 20 and at least partially covering the substrate 10; and the silver paste layer 40 at least partially covers the polarizer 30, is attached to the side surface of the polarizer 30 to extend and at least partially covers the conductive layer 20 and the substrate 10.

The utility model discloses set up conducting layer 20 between polaroid 30 and base plate 10, conducting layer 20 is connected polaroid 30 and silver thick liquid layer 40, even use display panel to lead to polaroid 30 shrink back, and conducting layer 20 still can connect polaroid 30 and silver thick liquid layer 40, consequently can stabilize display panel's antistatic effect.

As shown in fig. 5 and 6, the conductive layer 20 covers at least one side or at least one corner of the substrate 10, that is, as long as the conductive layer 20 can connect the polarizer 30 and the silver paste layer 40, it is not necessary to cover the conductive layer 20 on the substrate 10 entirely, saving materials and improving production efficiency.

As shown in fig. 7, in the present embodiment, the conductive layer 20 preferably covers the outer periphery of the substrate 10. The conductive layer 20 is ensured to be capable of connecting the polarizer 30 and the silver paste layer 40 and simultaneously saving materials.

The conductive layer 20 is a metal conductive layer, and/or a transparent conductive layer. Since the conductive layer 20 is disposed at the edge of the substrate 10, the display area of the display panel is avoided, and thus, the conductive layer 20 may be transparent or opaque. The metal conducting layer is made of metal with good conductivity, such as: copper; the transparent conducting layer is made of materials with high transmittance, such as: indium tin oxide.

The polarizer 30 includes a glue layer 31, a first protective layer 32, a polarizing layer 33, and a second protective layer 34, which are stacked. In this embodiment, the polarizer 30 is preferably an AS polarizer. The AS polarizer is a highly conductive antistatic polarizer. Since the touch panel function of the display panel in this embodiment is embedded in the liquid crystal pixel, the display panel is lighter and thinner, has higher touch precision and better optical performance, but the surface of the display panel needs a high-impedance film, and the AS polarizer ensures antistatic property and can save cost.

Preferably, the adhesive layer 31 is a pressure sensitive adhesive. Specifically, the resistance of the adhesive layer 31 is 10 for a pressure sensitive adhesive having high conductivity ⁸ And omega is about.

In the present embodiment, the substrate 10 is preferably a glass substrate.
