Abstract

The invention discloses a metal grid structure for a capacitive touch screen, a touch display device and a mobile terminal. The metal grid structure comprises a first metal grid layer, a first coating layer, a first optical adhesive layer, a second metal grid layer and a second coating layer which are arranged in sequence, the first metal grid layer is coated with the first coating layer, the thickness of the first coating layer is smaller than that of the first metal grid layer, the second metal grid layer is coated with the second coating layer, and the thickness of the second coating layer is smaller than that of the second metal grid layer. The structure can solve the problems that an existing touch screen is thin in copper film, thick in base material, low in transmittance and large in reflectivity, and the economical efficiency and the conductivity of products are effectively improved. Compared with an existing metal grid structure, due to the fact that no polymer base material exists, the overall thickness is obviously reduced, the total transmittance of the thin film is improved, and the touch screen is light and thin.

Description

technical field [0001] The invention relates to the field of optical films, in particular to a metal grid structure for a capacitive touch screen, a touch display device and a mobile terminal. Background technique [0002] With the development of touch technology, traditional resistive touch screens are gradually replaced by capacitive touch screens that are thinner and have better touch performance. In many capacitive touch screens, metal mesh has been widely used in the industry. [0003] At present, there are two metal grid technologies widely used in the industry: copper metal grid technology and silver halide nanoparticle metal grid technology. Both of these two technologies make metal grid electrodes on polyester resin (PET) substrates, and then use OCA film bonding technology to bond PET transparent conductive films on the glass cover to form capacitive touch screens with GFF or GF2 structure. [0004] Such as figure 1 As shown, the GFF structure includes an upper ...
