Abstract
The utility model provides a projection-type capacitor touch screen including a strengthened glass 10, optical cements (20, 40 and 60) and a three-layer ITO film; the three-layer ITO film comprises an upper-layer ITO film 30, a middle-layer ITO film 50 and a lower-layer ITO film 70; the upper-layer ITO film 30 in the three-layer ITO film serves as an X electrode, the middle-layer ITO film 50 serves as a Y electrode, and the lower-layer ITO film 70 serves as a shielding layer. The optical glass structure utilizing the three-layer ITO film to replace a multi-layer coated, so as to achieve simple processing technique, low probability of breakage, and avoid a difficult problem that bubbles are easily generated when two pieces of glass are pasted together with the optical cement and the paste is difficult. Meanwhile, the thickness of the projection-type capacitor touch screen is greatly reduced; the thickness of the thinnest three-layer ITO film can achieve 0.1 to 0.25mm; and the utility model also has the advantages that the cost of capacitor touch screens is reduced, the rate of good product (up to 80 percent) is improved, and the like.
Description
Technical field
The utility model belongs to a kind of touch-screen, particularly a kind of projection-type capacitive touch screen.
Background technology
At present, the capacitance touch screen that generally uses of market all is the structure that adopts the optical glass of tempered glass+optical cement+multicoating.This structure is at 5 layers of coating of optical glass front sputter [ITO (tin indium oxide) conducting film (x electrode)+SiO
2(silicon dioxide) insulation course+ITO (tin indium oxide) conducting film (y electrode)+molybdenum aluminium molybdenum lead-in wire+SiO
2(silicon dioxide) protective seam], in 2 layers of coating of reverse side sputter [ITO (tin indium oxide) conducting film (electro-magnetic screen layer)+molybdenum aluminium molybdenum lead-in wire] of optical glass, use optics glue bond one deck tempered glass more then as operating surface.
There is following problem in this constructed products: 1, the optical glass that adopts need be at the plated film of tow sides repeated multiple times, and the composition of every layer of plated film is also different, cause processing technology very complicated like this, the bad optical glass of whole multicoating that all will cause of any one deck plated film becomes waste product.2, plated film on glass needs many production lines, drops into greatlyyer, and the cost of investment of processing this product is too high; 3, be easy to generate bubble when two sheet glass being pasted together and be difficult to and get rid of with optical cement, need expensive special froth breaking equipment to solve, strengthen production cost; 4, the tempered glass of multicoating damages easily when making or use and is broken; 5, (be about 0.55～1.0mm), cause product thickness thicker because the optical glass that this structure adopts is thicker; Yields is low, and the yields of colleague's production at present only reaches 40%.
Summary of the invention
The purpose of this utility model is to provide that a kind of not cracky, processing easily, cost of products are lower, a kind of projection-type capacitive touch screen of thin thickness, the production line that need not throw big capital again, yields height (reaching 80% approximately).
A kind of projection-type capacitive touch screen provided by the utility model is to be made of tempered glass, optical cement and three layers of ito thin film.Wherein said three layers of ito thin film are made up of upper strata, middle layer and lower floor's ito thin film, and every layer of ito thin film is made of mylar and ITO coating respectively.With optical cement upper strata ito thin film and middle layer ito thin film and lower floor's ito thin film are pasted together, use optics glue bond one deck tempered glass at last again as operating surface.Upper strata ito thin film in said three layers of ito thin film is as the X electrode, and the middle layer ito thin film is as the Y electrode, and lower floor's ito thin film is as screen layer.
Owing to adopt three layers of ito thin film to replace the structure of the optical glass of multicoatings, make its processing technology simple, cracky has not been exempted a difficult problem that is easy to generate bubble when with optical cement two sheet glass being pasted together and is difficult to fit; Product thickness is greatly reduced, and said three layers of ito thin film are the thinnest can accomplish 0.1～0.25mm.Have the reduction cost of products, improve yields advantages such as (up to 80%).
