Problems solved by technology

[0006] Currently commonly used OGS structures such as figure 2 As shown, the ITO pattern is directly made on the cover plate, that is, the ITO film is directly plated on the protective glass by vacuum magnetron sputtering method, and the ITO layer is made by exposure and etching methods, so as to achieve the same effect, but such a touch screen is transparent. The pass rate is higher than that of the traditional touch screen structure technology (structure such as figure 1 ) has been improved, but it is only suitable for products with high ITO film resistance (75-350 ohms, low film thickness). For products with low ITO film resistance (0-75 ohms. high film thickness), the ITO pattern is obvious , affecting the appearance standard

Abstract

The invention discloses a capacitor screen OGS (One Glass Solution) shadow eliminating structure. A layer of optics antireflection film is arranged between the upper surface of a touch screen layer of the capacitor screen and a protective glass and between the lower surface of the touch screen layer of the capacitor screen and a resin protective layer respectively. An OGS structure touch screen, provided by the invention, adopts a structure that IIMs and ITO (Indium Tin Oxide) upper layers are plated on the lower sides of ITO film layers, and an IIM is plated on the lower side of an OC light resistance protective layer, ITO pattern effect can be eliminated, and the transmittance is high.

Description

technical field [0001] The invention relates to a capacitive touch screen structure and a production process thereof. Background technique [0002] As a new human-computer interaction device, touch screen is used instead of mouse and keyboard, and it has become the simplest and most convenient input device at present. When producing touch screens, designers can design various user interfaces through software. Users do not need special operation knowledge. They only need to tap the corresponding position on the display screen according to the function icon to realize the required operation. [0003] With the rapid development of social progress, people's pursuit of touch screen is getting higher and higher. In order to meet the needs of ultra-thin smart terminals and improve display effects, the OGS (One glass solution) structure has been developed, that is, the technology of directly forming an ITO conductive film and sensors on the protective glass (cover plate), so that a...
