The capacitive touch screen has the advantages that the visible range printing ink is arranged on the plastic film cover plate, the manufacturing process is simple, yield is high, cost is low, the capacitive touch screen can be manufactured into different colors so as to meet the personalization requirements of consumers, and the capacitive touch screen is an ideal structure and represents the ultimate direction of development.
Description
Technical field
The utility model relates to the touch-screen field, relates in particular to capacitance touch screen.
Background technology
Present capacitance touch screen is used widely, present capacitance touch screen structure has OGS(One glass solution) structure: the technology that on cover glass, directly forms ITO conducting film and sensor, a glass plays the double action of cover glass and touch sensor simultaneously, from technological layer, the OGS technology possesses following advantage than the G/G touch technology of present main flow: simple in structure, light, thin, light transmission is good; Owing to save a slice glass substrate and bonding process, be beneficial to and reduce production costs, improve the product yield.But this technology faces processing procedure difficulty, yield and promotes difficulty and make problems such as volume production manufacturer is less at present.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of capacitance touch screen.
The utility model provides a kind of capacitance touch screen, comprise plastic sheeting cover plate, glass substrate, flexible PCB, described glass substrate etching has transparency conducting layer, the described flexible PCB of described glass substrate below binding, described glass substrate top is fitted with described plastic sheeting cover plate, and described plastic sheeting cover plate is provided with visible area printing ink.
As further improvement of the utility model, be provided with optical cement between described glass substrate and the described plastic sheeting cover plate, by described optical cement described glass substrate and described plastic sheeting cover plate are fit together.
As further improvement of the utility model, described plastic sheeting cover sheet thickness is 0.188 millimeter or 0.25 millimeter.
As further improvement of the utility model, described optical cement thickness is 0.1 millimeter or 0.125 millimeter.
As further improvement of the utility model, described thickness of glass substrate is 0.7 millimeter.
The beneficial effects of the utility model are: capacitance touch screen of the present utility model, visible area printing ink is made on the plastic sheeting cover plate, and processing procedure is simple, yield is high, cost is low, can do the personalization that different colours satisfies the consumer, being the ideal structure of capacitance plate, is the final direction of development.
Description of drawings
Fig. 1 is capacitance touch screen cross-sectional view of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of capacitance touch screen, comprise plastic sheeting cover plate 1, glass substrate 2, flexible PCB 3, described glass substrate 2 etchings have transparency conducting layer 4, described flexible PCB 3 is bound in described glass substrate 2 belows, described glass substrate 2 tops are fitted with described plastic sheeting cover plate 1, and described plastic sheeting cover plate 1 is provided with visible area printing ink.
Be provided with optical cement 5 between described glass substrate 2 and the described plastic sheeting cover plate 1, by described optical cement 5 described glass substrate 2 fit together with described plastic sheeting cover plate 1.
Described plastic sheeting cover plate 1 thickness is 0.188 millimeter or 0.25 millimeter.
Described optical cement 5 thickness are 0.1 millimeter or 0.125 millimeter.
Described glass substrate 2 thickness are 0.7 millimeter.
The OCA------transparent optical cement, FPC------flexible PCB, ITO------transparency conducting layer (tin indium oxide), PET------plastic sheeting.
OGS product in the background technology is because the printing ink that has viewfinder area to use below the ITO conductive layer, cause the processing procedure difficulty, optimum low, cost is high, do not possess production.Capacitance touch screen of the present utility model is made in visible area printing ink on the plastic sheeting cover plate, and processing procedure is simple, yield is high, cost is low, can do the personalization that different colours satisfies the consumer, is the ideal structure of capacitance plate, is the final direction of development.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
