Abstract
The invention provides a full-lamination process of a touch display module. According to the process, two working procedures are arranged to check the quality of half-finished products, and defective products cannot enter the next working procedure, so that the yield of products is remarkably improved. A touch screen is adhered to an upper polarization sheet of a half-finished display screen without a backlight sheet through optical cement, and then the backlight sheet is clamped with a glass substrate of the half-finished touch display module, so that the optical cement is prevented from spilling into the backlight sheet, the normal light transmission of the backlight sheet is guaranteed, defective products are avoided, and the production cost is lowered.
Description
Technical field
The invention belongs to the touch screen technology field, relate in particular to a kind of touch-control and show the full attaching process of module.
Background technology
Along with the client will come higher to the demonstration of smart mobile phone and touch requirement, after numerous well-known manufacturers attempt adopting touch-control to show the full coating technique of module, the benefit that the product attenuation brings, not only improved the design of product, also simplified supply chain production procedure, reduced cost, no longer need to purchase respectively touch-screen and liquid crystal panel to different vendor.Full coating technique adopts liquid optical cement or solid state optics glue that display screen and touch-screen are pasted together fully in seamless mode, full coating technique is except providing better display effect, touch-screen is also because combining closely intensity is promoted to some extent with display screen, reduced the interference that the display screen noise causes the touch-control signal, and need not consider dust protection and anti-steam, so the touch-screen frame need not be considered the width of fitting, can make the touch-screen frame narrower, simultaneously because considering the laminating intensity of double-sided adhesive, also contribute to narrow frame design, frame can be accomplished narrower.
At present, the cost of full sticking touch control demonstration module costliness and yields are hanged down and are made a lot of manufacturers can't realize volume production, cause the manufacturer of the full coating technique of current practical application very few.Main laminating type is that optical cement directly is fitted on the upper polaroid of display screen finished product now, touch-screen is located on the optical cement on upper polaroid again, touch-screen and display screen finished product are bonded together, this manufacturing process can cause optical cement to overflow in the backlight of display screen finished product, make normally printing opacity of backlight, cause product bad, increased production cost.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide the touch-control that a kind of cost is low, yields is high to show the full attaching process of module.
The present invention is achieved in that a kind of touch-control shows the full attaching process of module, comprises the following steps:
(1) the upper polaroid of display screen, glass substrate and lower polaroid are stacked gradually to bonding from top to bottom, make the display screen semi-finished product;
(2) check whether the display screen semi-finished product are non-defective unit, if the display screen semi-finished product are non-defective unit, continue next step operation;
(3) the display screen semi-finished product, after verifying as non-defective unit, are located at optical cement on the half-finished upper polaroid of display screen;
(4) touch-screen is located on the optical cement on upper polaroid, touch-screen is bonded together by optical cement and upper polaroid, make touch-control and show the module semi-finished product;
(5) detect touch-control and show whether the module semi-finished product are non-defective unit, if touch-control shows that the module semi-finished product are non-defective unit, continue next step operation;
(6) touch-control shows that the module semi-finished product are after verifying as non-defective unit, and backlight and touch-control are shown to the half-finished glass substrate of module is connected together, and makes touch-control and shows the module finished product.
Particularly, described optical cement is solid state optics glue, and described touch-screen utilizes defoaming device to remove the bubble between described touch-screen and upper polaroid after being bonded together by described solid state optics glue and described upper polaroid.
Particularly, described optical cement is liquid optical cement, after described touch-screen is bonded together by described liquid optical cement and described upper polaroid, passes through Self-leveling, precuring and wipes the glue process that overflows and realize solidifying fully.
Check half-finished quality because technique of the present invention is provided with two procedures, defective products can not flow into next procedure, has therefore significantly improved product yield.Due to the present invention be by touch-screen by optical cement with without the half-finished upper polaroid of the display screen of backlight, carry out bonding, after touch-screen and upper polaroid are bonding, again backlight and touch-control are shown to the half-finished glass substrate of module is connected together, therefore avoided optical cement to overflow in backlight, guaranteed normally printing opacity of backlight, can not cause product bad, reduce production cost.
The specific embodiment
A kind of touch-control that the embodiment of the present invention provides shows the full attaching process of module, comprises the following steps:
(1) the upper polaroid of display screen, glass substrate and lower polaroid are stacked gradually to bonding from top to bottom, make the display screen semi-finished product;
(2) check whether the display screen semi-finished product are non-defective unit, if the display screen semi-finished product are non-defective unit, continue next step operation;
(3) the display screen semi-finished product, after verifying as non-defective unit, are located at optical cement on the half-finished upper polaroid of display screen;
(4) touch-screen is located on the optical cement on upper polaroid, touch-screen is bonded together by optical cement and upper polaroid, make touch-control and show the module semi-finished product;
(5) detect touch-control and show whether the module semi-finished product are non-defective unit, if touch-control shows that the module semi-finished product are non-defective unit, continue next step operation;
(6) touch-control shows that the module semi-finished product are after verifying as non-defective unit, and backlight and touch-control are shown to the half-finished glass substrate of module is connected together, and makes touch-control and shows the module finished product.
Particularly, described optical cement is solid state optics glue, during assembling, after touch-screen is bonded together by solid state optics glue and upper polaroid, then utilizes defoaming device to remove the bubble between touch-screen and upper polaroid.
Particularly, described optical cement is liquid optical cement, during assembling, utilize point glue equipment that liquid optical cement is selected on upper polaroid, then, after touch-screen is bonded together by liquid optical cement and upper polaroid, finally by crossing Self-leveling, precuring and wiping the glue process that overflows and realize solidifying fully.
Check half-finished quality because technique of the present invention is provided with two procedures, defective products can not flow into next procedure, has therefore significantly improved product yield.Due to the present invention be by touch-screen by optical cement with without the half-finished upper polaroid of the display screen of backlight, carry out bonding, after touch-screen and upper polaroid are bonding, again backlight and touch-control are shown to the half-finished glass substrate of module is connected together, therefore avoided optical cement to overflow in backlight, guaranteed normally printing opacity of backlight, can not cause product bad, reduce production cost.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
