Abstract
The utility model provides a monolayer FILM capacitive touch screen which is composed of polyester film (10) coated with ITO conductive film coating, optical cement and common glass (20). The polyester film coated with ITO conductive film coating and the common glass are cemented by the optical cement. The monolayer work layer is composed of polyester film (22) and ITO conductive film coating (21). As the work layer has only one layer of ITO coating polyester film and is less than 0.1mm in thickness, the volume of the product is greatly reduced, and meanwhile the processing is easy, breakage is unlikely to occur, and the utility model has the advantages of low cost, extremely high yield (as high as 85%) and the like.
Description
Technical field
The utility model belongs to a kind of touch-screen, is a kind of individual layer conductive film capacitance touch screen
Background technology
At present, the capacitance touch screen that generally use in market has several structures, and having a kind of is the single layer structure that adopts glass, and this structure is behind surface of ordinary glass plating indium oxide layer tin (ITO) conducting film, unifies layer simple glass as protective seam with the optics sticker again.The material that this arrangement works district is adopted mainly is a glass, when making and use,
1, to reach client's quality requirements, need carry out intensive treatment, and need multicoating (indium tin oxide layer, silicon dioxide layer, plain conductor film etc.) glass, and plated film, special-shaped cutting production technology complexity, difficulty is very big, inefficiency;
2, produce and damage easily when using and broken, quality can't guarantee;
3, this structure is used optical cement to carry out the two sides stickup and is easy to generate bubble, and is difficult to get rid of, and makes it to be difficult for fitting, and technical difficulty is bigger;
4, because the glass that this structure adopts is thicker (is about 0.55～0.7mm), causes product heaviness and volume bigger.
5, this kind structure technology difficulty is big, causes production efficiency and yields low (only reaching about 40%), the production equipment costliness, and consume is big, causes production cost higher;
Another kind is to adopt sandwich construction, and working lining is conductive film+optical cement+conductive film+optical cement+conductive film+optical cement structure, its drawback also clearly:
(1) the stickup number of plies is too many, and the technology more complicated is careless slightly, just easily foreign material is mingled with in the product during combination, causes bad order.
(2) number of layers is many, and material cost is relatively expensive, and the client is also difficult to accept;
(3) though technology difficulty has big change than first kind, and air bubble problem can not be eradicated fully, yields is not high yet, and about 80%, production efficiency does not catch up with customer demand.
In view of several touch-screens in the market can not adapt to different clients' demand, high-level efficiency, low cost, low-loss are the themes of present manufacturing.Therefore, strengthening the R﹠D intensity of individual layer conductive film capacitance plate, release the more product of meeting the market requirement, strengthen the market competitiveness, is to produce the extremely urgent task of touch-screen enterprise.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of individual layer conductive film capacitance touch screen, and it is pasted, and the number of plies is few, and technology is simple, is difficult for during combination foreign material are mingled with in the product, causes bad order.
Address the above problem, the technical scheme that the utility model adopted is:
A kind of individual layer conductive film capacitance touch screen is characterized in that: the mylar that is scribbled indium-tin oxide coatings by simple glass and the inside constitutes so that optical cement is bonding.
Described the inside scribbles the gross thickness of mylar of indium-tin oxide coatings less than 0.1mm.
It is working lining by layer of conductive film for an individual layer conductive film capacitance touch screen, pastes the glass (panel) that one deck serves as operation interface with optical cement then and constitutes
Its working lining is to make of conductive film, the material of conductive film is to plate conductive layer (tin indium oxide) at mylar, process etching and printed silver tree lace road and dielectric ink form, because its working lining has only very thin layer of conductive film, so called after individual layer conductive film capacitance plate.
Beneficial effect:
Because the material that working lining adopts mainly is the mylar that one deck is coated with conducting film, make finished product after, its capacitance plate has: gross thickness＜0.1mm, the volume of product is very little, weight is extremely light, the while handling ease, and cost is minimum, the higher advantages such as (up to 85%) of yields.
Though the individual layer capacitance touch screen is also arranged on the market, individual layer conductive film capacitance touch screen material processed, technology, the technical characterstic of taking charge of exploitation with me are completely different.With respect to single-glass touch-screen on the market, it is with the obvious advantage that I take charge of individual layer conductive film capacitance touch screen.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Accompanying drawing is that the composition of individual layer conductive film capacitance touch screen is analysed and observe decomposing schematic representation.
Embodiment
From accompanying drawing, can see,
To be the mylar 22 that scribbles indium-tin oxide coatings 21 by simple glass 11 and the inside constitute so that optical cement 12 is bonding a kind of individual layer conductive film capacitance touch screen provided by the utility model, and wherein the inside scribbles the gross thickness of indium-tin oxide coatings 21 and mylar 22 less than 0.1mm.
Perhaps also we can say, this individual layer capacitance touch screen is to be made of the working lining 20 that top panel layer 10 adds the bottom surface, panel layer 10 is again that the optical cement 12 by top glass 11 that is printed with multicolour pattern and beneath stickup usefulness constitutes, and working lining 20 is to be constituted in order by top indium-tin oxide coatings 21 and beneath mylar 22.
Its processing mode is:
A, I take charge of the needs according to the client, with printing color pattern on glass and excision forming
B is at the optical cement that sticks on glass;
C handles mylar through processing, the front plates indium-tin oxide coatings (raw material supplier's production);
D, I take charge of according to product needed, and conductive film through after the etching, is formed different conducting wires;
E, printing conductive cabling on conductive film after the process etching, and after the oven dry, working lining (circuit) is finished;
F behind circuit pack assembled panel (glass), is individual layer conductive film capacitance touch screen finished product.
The 10th, be the working line layer as the panel 20 of operation interface.
Described working lining adopts indium oxide layer tin coating (21) and mylar (22), and the market touch-screen is compared in its thickness＜0.1, the volume of product dwindles greatly, and weight alleviates greatly, makes handling ease simultaneously, product has cost and is reduced to greatest extent, and yields is up to advantage such as 85%.
Claims (2)
1. individual layer conductive film capacitance touch screen is characterized in that: by simple glass (11) and the mylar (22) that scribbles indium-tin oxide coatings (21) with the bonding formation of optical cement (12).
