Abstract

The invention discloses a touch screen and a manufacturing method thereof. The manufacturing method comprises the following steps of forming a film, on which any patterns can be printed, on a transparent PET / PC sheet, and forming a viewing window or other patterns on the PET / PC sheet through the film; performing hot pressing and forming on the PET / PC sheet; blanking the PET / PC sheet subjected to hot pressing and forming to form a PET / PC front panel; performing hot pressing and forming on a film circuit or an ITO circuit and then blanking; performing injection molding between the PET / PC front panel and the film circuit / ITO circuit to form a plastic main body. According to the manufacturing method disclosed by the invention, the problems that a glass curved surface or an irregular special-shaped surface is difficult to laminate and is high in rejection ratio are effectively solved; meanwhile, the manufacturing cost of glass is avoided, OCA (Optical Clear Adhesive) laminating working procedures are omitted, and a multi-person operation working procedure is omitted; the PET / PC sheet replaces a glass lenses, so that the subsequent laminating procedure of glass is solved; the glass is subjected to injection molding by an injection molding process to obtain a finished product which can be assembled on a required product.

Description

technical field [0001] The invention relates to a touch screen, in particular to a mobile phone and various electronic products, medical treatment, automotive touch instruments and touch screens of home appliances. The invention also relates to a manufacturing method of the touch screen. Background technique [0002] Existing touch screens all adopt the method of bonding flat glass, which has the advantages of high hardness, good flatness, thin overall thickness and high transparency of the glass. However, the touch screen with this structure also has disadvantages. The color of the glass is monotonous, and it is impossible to achieve multiple printings on the special-shaped surface. The poor rate of bonding of touch lines is extremely high. [0003] IMD / IML (in-mold decoration technology) is an internationally popular surface decoration technology in the world today. Its products have excellent durability, solvent resistance, abrasion resistance, scratch resistance, and no...
