Abstract
The invention relates to a capacitance touch control screen which comprises a cover plate, a touch control layer, an optical adhesive layer and a display module which are arranged from top to bottom in sequence, wherein a gap is formed between the cover plate and the upper surface of the touch control layer; the lower surface of the touch control layer is adhered to the display module through the optical adhesive layer. As the gap into which air is filled is formed between the cover plate and the upper surface of the touch control layer, the cover plate does not need to be adhered to the touch control layer through the optical adhesive in the production process, and the production procedures and the time cost are reduced; in addition, in the production and use process, if the cover plate is cracked or broken, only the cover plate needs to be replaced, and thus the repairing cost is lowered.
Description
Technical field
The touch-control display technique that the present invention relates to human-computer interaction device, is specifically related to capacitive touch screen.
Background technology
Along with the development of touch-control display technique, touch screen (touch-control or touch display screen) is widely used in various electronic equipments, as smart mobile phone, panel computer, notebook computer, TV, the commercial unit etc. that comprises touching display screen.
At present, touching display screen generally all comprises cover plate (cover glass), the first optics glue-line, touch control layer, air layer or the second optics glue-line, the demonstration module of arranging successively from top to bottom; Described cover plate is fitted by the upper surface of the first optics glue-line and described touch control layer; Between the lower surface of described touch control layer and described demonstration module, by the second optical cement laminating, close, or between forms air layer (as shown in Figure 1).Described demonstration module is that liquid crystal display upper surface laminating polaroid forms.Also have plenty of touch control layer Direct Electroplating in cover plate medial surface.
Also having a kind of is the not high ground structure of production yield just rising recently, and its touching display screen comprises cover plate, optics glue-line, the touch-control of arranging successively from top to bottom and shows module; Described cover plate shows the upper surface laminating (as shown in Figure 2) of module by optics glue-line and described touch-control; Described touch-control shows that module is in liquid crystal display surface (being in the industry cycle called On-Cell technology) or touch-control circuit is arranged to liquid crystal display inside (being in the industry cycle the called In-Cell technology) polaroid of fitting again forms by touch-control circuit Direct Electroplating.
In addition, along with Mobile Communication Service industry and multimedia fast development, as portable terminals such as dull and stereotyped smart mobile phone, panel computers, waited until rapidly universally, almost dull and stereotyped smart mobile phone of staff or panel computer, and carry, be so fond that will not let out of one's hand.So just occurred having every day the cover plate of the touch screen of a large amount of dull and stereotyped smart mobile phones or panel computer to be occurred by the thing of falling row or break.
Yet just as previously mentioned, described cover plate is to fit by the upper surface of the first optics glue-line and described touch control layer, described cover plate and touch control layer have formed a combination; Or described cover plate shows that by optical cement and described touch-control module is sticked to form a combination.So just occur, once cover plate is fallen row or is broken, must change described cover plate and touch control layer has formed a combination or has changed by described cover plate and described touch-control and shown that module is sticked to form a combination, even touch control layer or touch-control show that module is that intact state also has to change, increase maintenance cost, and then caused the generation of a large amount of wasting phenomenons.
Meanwhile, because said structure needs described cover plate and touch control layer or touch-control to show that module fits by optical cement in process of production, production process and time cost have also been increased.
Summary of the invention
Order of the present invention is to provide a kind of structure of novel capacitive touch screen, effectively reduces production costs and maintenance cost.
The object of the invention is to realize by following technological means:
A capacitive touch screen, comprises cover plate, touch control layer, optics glue-line, the demonstration module of arranging successively from top to bottom; Between described cover plate and the upper surface of described touch control layer, form gap; Between the lower surface of described touch control layer and described demonstration module, by optical cement laminating, close.
In described gap, be filled with gas, or be evacuated.
The thickness in described gap is less than or equal to 1mm.
Sensor circuit in described touch control layer and driving circuit are arranged on a side of described touch control layer.
Between the lower surface of described touch control layer and described demonstration module, form the second gap.
A capacitive touch screen, comprises that cover plate, the touch-control of arranging successively show module from top to bottom; Between the upper surface of described cover plate and described touch-control demonstration module, form gap.
In described gap, be filled with gas, or be evacuated.
The thickness in described gap is less than or equal to 1mm.
The present invention also provides a kind of electronic equipment.
Use an electronic equipment for above-mentioned capacitive touch screen, also comprise battery, control module and housing; Described capacitive touch screen, control module and battery are all arranged in the formed encirclement of housing space.
The present invention is owing to forming the gap that is filled with air between described cover plate and the upper surface of described touch control layer or described touch-control demonstration module; Do not need in process of production described cover plate and touch control layer or touch-control to show that module fits by optical cement, do not form a combination between the two; Production process and time cost have been reduced; In addition, in production and use procedure, once occur that cover plate just only need to be changed described cover plate by the situation of being fallen row or breaking, and has reduced maintenance cost.
