Touch panel

Abstract

The invention relates to a touch panel, comprising a metal mesh, a light transmitting plate, an optical adhesive, a film body and a glue body. The optical adhesive is bonded between the metal mesh and the light transmitting plate. The film body covers one face, far away from the light transmitting plate, of the metal mesh. The glue body surrounds the edge of the metal mesh, and is used for connecting the film body with the light transmitting plate, so that the metal mesh is sealed by the film body, the glue body and the light transmitting plate. Therefore, the metal mesh cannot be in contact with air, and silver ions are not dissociated due to the fact that silver oxide molecules on the surface of the metal mesh cannot be chemically reacted with water molecules in the air, so that the silver ion migration phenomenon of the metal mesh is effectively overcome.

Description

Technical field [0001] The invention relates to a touch panel. Background technique [0002] With the rapid development of electronic products, the operation mode of controlling electronic products through touch panels has gradually become popular. Moreover, since the electronic product can be directly controlled by only touching the display screen of the touch panel, its simple operation and easy-to-use characteristics are also very popular among users. [0003] In the production process of touch panels, due to the lower resistance value of the metal mesh (Metal Mesh), the indium tin oxide (ITO) structure in the touch panel is gradually replaced by the material of the metal mesh . [0004] However, the surface of the metal mesh has silver oxide (Ag 2 O) molecules. When these silver oxide molecules come into contact with water molecules in the air, they easily cause the dissociation of silver ions (Ag+). Then, under the action of the electric field, silver ions will flow from the ...

Problems solved by technology

[0004] However, the surface of the metal mesh has silver oxide (Ag 2 O) molecules, when these silver oxide molecules come into contact with water molecules in the air, it is easy to cause the dissociation of silver ions (Ag+)

Then, under the action of the electric field, the silver ions will flow from the area with higher potential to the area with lower potential on the metal grid, resulting in the phenomenon of silver ion migration (Silver Ions’Migration).

More specifically, the migration of silver ions can cause bypasses between conductors that are not electrically connected, causing insulation degradation or even short circuits, which in turn lead to poor function of the touch panel
