Abstract

The invention discloses a multi-point touch screen with single-layer film. The multi-point touch screen with the single-layer film comprises a glass covering plate and PET film, wherein an indium tin oxide conducting circuit is etched on one surface of the glass covering plate, the surface of the glass covering plate etched with the indium tin oxide conducting circuit adheres to one surface of the PET film through optical cement, and an indium tin oxide conducting circuit is etched on the other surface of the PET film. According to the multi-point touch screen with the single-layer film, the circuits are printed and etched on the tempered glass covering plate and a functional piece of a single-layer film structure at the same time, then the single-layer film is attached onto the tempered glass covering plate, therefore, an existing double-layer film structure is replaced, and the multi-point functional piece is obtained, the total thickness of the touch screen is decreased. Meanwhile, production procedures are simplified, so that production cost is reduced.

Description

technical field [0001] The invention relates to touch screen manufacturing technology, in particular to a single-layer film multi-touch touch screen and a production method thereof. Background technique [0002] At present, the multi-touch solution of the traditional film structure in the industry adopts the cover glass + double-layer film structure, etching and silver paste printing are carried out on the two-layer pet film respectively, and then the two-layer pet film is pasted on the surface with optical glue. Together, the functional sheets that make up our desired bilayer membrane structure. The traditional solution requires etching and printing on the two layers of film respectively, which has the disadvantages of large thickness and high cost, and is difficult to mass-produce on some low-cost touch screens that require multi-touch. Contents of the invention [0003] The purpose of the present invention is to provide a single-layer film multi-touch touch screen, whi...
