Description
Technical field:
The present invention relates to electronic product technical field of producing, particularly relate to a kind of attaching process of touch-screen.
Background technology:
Along with the high speed development of electronic technology, the use of touch-screen is more and more wider, especially the significant progress obtained in mobile phone, along with mobile phone market scale continues to increase, and requiring more and more higher to mobile intelligent, facilitation degree, touch-screen also can be more and more universal as a kind of application of man-machine interface on mobile phone the most friendly.Except mobile phone, touch-screen is also more and more extensive in the application of vehicle electric field.Along with the fast development of car industry, the requirement of people to automobile entertainment information system is also more and more higher, and in onboard navigation system, car, video and music entertainment system etc. start to be popularized.Touch-screen market for portable navigation device and other electronic equipments will reach 600,000,000 dollars in 2012.Retail business is also the staple market of future touchscreens application.Along with commercial POS(point of sale) systems grow is applied in the industry such as retail business, catering trade manyly, and the application of touch-screen on POS system is also more and more universal.The market scale of whole world retail business touch-screen is estimated to account for 18.2% of touch-screen total size by 2012, and sales volume reaches 800,000,000 dollars.In addition, along with the release of windowS7 operating system, this growth also will touch-screen being driven in PC industry.Add the touch-control in the fields such as touch-screen industrial control field, medical field, common query system, lottery industry field, self-service terminal, the market space of touch-screen has the trend of constantly amplifying.
The production scale also expanding day of touch-screen; the topmost feeldevice of touch-screen is mounted in the induction substrate below transparent surface cover; transparent surface cover is arranged on the outer end of induction substrate in the product; play the effect of protection induction substrate; below induction substrate, display screen is set; transparent surface cover and induction substrate and display screen between coupled together by OCA optical cement; OCA optical cement has the high grade of transparency; light transmittance reaches more than 99%; at strong illumination, under hot and humid environment, use also harmless outward appearance.At present, produced by the laminating of OCA glue between transparent surface cover and induction substrate and display screen, in a lot of enterprise, assembled by manual assembly, can cause OCA glue-line unbalance stress, local indexes of refraction changes or produces bubble, affects display screen display effect, product rejection rate is high, and production efficiency is low.
Summary of the invention:
Object of the present invention is exactly provide a kind of attaching process of the touch-screen overcome the above problems for producing by the laminating of OCA optical cement the deficiency that exists between the transparent surface cover of prior art and induction substrate.
To achieve these goals, the technical solution used in the present invention is:
An attaching process for touch-screen, described attaching process comprises following processing step:
A, by OCA optical cement two sides by transparent surface cover and induction substrate stress-free preliminary laminating;
B, in the side of induction substrate by the stress-free preliminary laminating display screen of OCA optical cement, form screen of just fitting;
C, will at least two pieces just fit screen neatly together superimposed, insert on the support supporting plate of the laminating chamber of make-up machine;
D, to vacuumize at the laminating chamber of make-up machine, start top board and press to the first laminating screen supported on supporting plate, under the pressure of vacuum and top board, just the fit induction substrate that shields and transparent surface cover of every part is fitted closely, completes the attaching process of display screen of the present invention.
Preferably, in described step a, also can first will will respond to substrate and the stress-free preliminary laminating of display screen by OCA optical cement two sides, tentatively be fitted transparent surface cover responding to substrate-side by OCA optical cement in stepb, thus screen of fitting at the beginning of formation.
Preferably, in described step b, just the quantity of laminating screen is 2-5 part.
Preferably, described display screen is LCDs.
Beneficial effect of the present invention is: the attaching process of a kind of touch-screen of the present invention, by OCA optical cement, transparent surface cover, induction substrate and display screen laminating are formed screen of just fitting together, first laminating screen more than superimposed two pieces, the laminating chamber being placed on make-up machine vacuumizes, and start top board and press to stacked first laminating screen, under the pressure of vacuum and top board, the induction substrate of the stacked every part of first laminating screen, transparent surface cover and display screen are fitted closely; Attaching process of the present invention, under the pressure of vacuum and top board under double action, uniform force, laminating closely, are effectively avoided manual assembly to assemble unbalance stress and are caused local indexes of refraction to change or produce bubble, promote touch-screen display effect, reduce waste product to produce, the qualification rate of improving product, reduces costs, and is being placed in the laminating of make-up machine additionally by first laminating screen more than superimposed two pieces, single completes the laminating of more than one piece product, enhances productivity.
Detailed description of the invention:
Embodiment 1,
The attaching process of the touch-screen of the present embodiment, when getting all the OCA optical cement, transparent surface cover, induction substrate and the display screen that match ready, attaching process comprises following processing step:
A, by OCA optical cement two sides by transparent surface cover and the stress-free preliminary laminating of induction substrate, OCA optical cement tear in use its one side mould release membrance, tear the stress-free preliminary laminating transparent surface cover of one side or the induction substrate of mould release membrance, tear the mould release membrance of OCA optical cement another side again, the induction substrate that stress-free preliminary laminating does not connect or transparent surface cover (use of the OCA optical cement of following steps and following examples is similar), stress-free preliminary laminating in the present invention also nisily to contact without pressure, just both are contacted naturally and make both preliminary combinations by the cementability of OCA optical cement, without adding artificial extruding force (being adapted in steps d and in following examples)
B, in the side of induction substrate by the stress-free preliminary laminating display screen of another OCA optical cement, form screen of just fitting;
