Abstract
The invention discloses a method for controlling glue overflow when liquid optical clear adhesive gluing, which includes the steps: (1) gluing panel glass of a capacitive touch screen and sensing lines by liquid optical clear adhesives; (2) wrapping the touch screen with a protecting film; (3) placing the touch screen in a vacuum mixer prior to pressurizing; and (4) taking the touch screen out and removing the protecting film after pressure relief of the vacuum mixer.
Description
Technical field
The present invention relates to the technical field of capacitive touch screen, relate to a kind of method of controlling the glue that overflows when liquid optical cement is fitted particularly.
Background technology
Touch-screen is a kind of remarkable input equipment that improves man machine operation interface, have intuitively, simply, advantage efficiently.Touch-screen has obtained to use widely in many electronic products, such as mobile phone, PDA (personal digital assistant), multimedia, public information inquiry system etc.Touch-screen mainly contains following four types, comprises resistance-type, condenser type, infrared and surface acoustic wave type touch-screen.
Past, because structure and the restriction that drives cost, and many-sided shortcoming such as touch-control distortion, the utilization scope of capacitive touch screen is very narrow.In the recent period, owing to updating of structure and signal processing technology, capacitive touch screen rises gradually.
According to textural classification, capacitive touch screen has two major types, and the one, Glass (glass) capacitive touch screen, another kind of is Film (film) capacitive touch screen.The principle of work of these two types of capacitive touch screens is the same, and still, its structure is different, and the Glass capacitive touch screen is made up of face glass and glass induction line, and the Film capacitive touch screen is made up of face glass and Film induction line.In the capacitive touch screen, fitting between face glass and the induction line is to adopt solid state optics glue, because the pressure of cost; Liquid optical cement is fitted and is also brought into use, and still, very large shortcoming of liquid optical cement is that it is liquid; In the applying process of touch-screen; Cause the glue that overflows easily, thereby have many culls, damaged the quality of product on the edge, surrounding of touch-screen.In order to address this problem, many technology and method have been proposed in the past, the coating glue amount such as the liquid optical cement of control designs the coated pattern of liquid optical cement etc.Still there is the glue problem of overflowing in these technology, can not be from thorough solution.
Summary of the invention
For overcoming the defective of prior art, overflow when the fitting method of glue of the liquid optical cement of control that the technical matters that the present invention will solve has provided a kind of better effects if.
Technical scheme of the present invention is: the method for excessive glue when the liquid optical cement of this control is fitted may further comprise the steps:
(1) face glass and the induction line with capacitive touch screen adopts liquid optical cement to glue;
(2) adopt diaphragm that this touch-screen is wrapped up;
(3) this touch-screen is placed in the deaeration machine pressurization;
(4) after the pressure release of deaeration machine, take out touch-screen, remove diaphragm.
Because in pressurization; Because the effect of air pressure will impel the face glass of touch-screen and induction line to press close to; Oppress liquid optical cement and be diffused into the whole plane of touch-screen because diaphragm is the surface of being close to touch-screen, can hinder liquid optical cement overflow touch-screen around.

Embodiment
Do further detailed description in the face of technical scheme of the present invention down.
The method of excessive glue when the liquid optical cement of this control is fitted may further comprise the steps:
(1) face glass and the induction line with capacitive touch screen adopts liquid optical cement to glue;
(2) adopt diaphragm that this touch-screen is wrapped up;
(3) this touch-screen is placed in the deaeration machine pressurization;
(4) after the pressure release of deaeration machine, take out touch-screen, remove diaphragm.
Because in pressurization; Because the effect of air pressure will impel the face glass of touch-screen and induction line to press close to; Oppress liquid optical cement and be diffused into the whole plane of touch-screen because diaphragm is the surface of being close to touch-screen, can hinder liquid optical cement overflow touch-screen around.
Preferably, the diaphragm in the step (2) is a polyethylene film, and thickness is 0.01～0.075mm.
Preferably, in the step (3), the pressure limit of pressurization is 1～10 atmospheric pressure.
Fig. 1 is the sectional view of capacitive touch screen.Capacitive touch screen comprises face glass 1, induction line 2, optical cement 3, FPC 4 and control chip 5.Optical cement 3 has solid state optics glue and liquid optical cement.Fig. 2 adopts liquid optical cement, the synoptic diagram after face glass 1 adheres to induction line 2.Usually, liquid optical cement is to be designed to specific pattern in coating, and the pattern of liquid optical cement coating is " worker " font among Fig. 2.After the face glass 1 of touch-screen and induction line 2 are bonding, adopt diaphragm 6 that it is wrapped up, as shown in Figure 3.The material of diaphragm 6 is preferably PE (tygon) material, and thickness is 0.01～0.075mm.Then, touch-screen is put in the deaeration machine pressurizes, the pressure limit of pressurization is preferably 1～10 atmospheric pressure.The agent structure of deaeration machine is the still of sealing, can pressurize and heats through pressurized air in it.The deaeration machine increases its still internal gas pressure, and with the increase of air pressure, diaphragm 6 more and more is adjacent to the surface of touch-screen; Simultaneously because the increase of air pressure, between the face glass 1 of touch-screen and the induction line 2 also gradually near; The liquid optical cement of coating between extruding wherein; Liquid optical cement is expanded, and occupies whole touch screen gradually, and is as shown in Figure 4.Be close to touch screen surface and diaphragm 6 all around owing to have, when liquid optical cement expanded to the edge of touch-screen, its expansion will be hindered, and finally was closed in the inside of touch-screen, and can overflow touch-screen.At last, remove the air pressure in the deaeration machine, take out touch-screen, and remove its surperficial diaphragm 6, obtain the touch-screen that adopts liquid optical cement to fit.Fig. 5 is a process flow diagram of the present invention.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs to the protection domain of technical scheme of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
