[embodiment]
For making object of the present invention, technical scheme and advantage are clearly understood, below in conjunction with drawings and Examples, are further elaborated to the present invention.Should be appreciated that specific embodiment described herein only for explaining the present invention, and be not used in this invention of restriction.
Refer to Fig. 1, the method for making 1 of a kind of touch control display of first embodiment of the invention comprises the following steps:
S1: touch-screen and liquid crystal display are accurately located, and reserve certain gap between.Position fixing process can adopt positioning equipment to carry out high-speed High Precision Automatic location, and the distance utilizing equipment to control well between touch-screen and liquid crystal display, is convenient to subsequent operation.Touch-screen can be touch screen or cover glass, and liquid crystal display can be TFT liquid crystal display, and also can be IPS liquid crystal display or OLED display screen, the brightness of liquid crystal display be larger, then its power consumption and thermal value also can correspondingly increase.When extraneous light is stronger, if touch control display is not through special process, then under the irradiation of extraneous light, the lumen of the extraneous light of touch control display overall reflective is comparatively large, but, in order to ensure serviceable life and the thermal diffusivity of liquid crystal display, it is too large that the lumen of general liquid crystal display all can not design, under such circumstances, the brightness after reflection of extraneous light is greater than the luminosity of liquid crystal display reality, so it is readable very poor under high light just to cause touch control display.
S2: the gap optical cement being added with catalyzer and rigidizer being injected touch-screen and liquid crystal display, optical cement is identical with the refractive index of touch-screen.Refractive index due to optical cement is 1.49, identical with the refractive index of touch-screen, so the extraneous light entering touch control display is after touch-screen, can not reflect through when optical cement, and the trend of light does not also change.When not having optical cement, light is after passing touch-screen, and enter air layer, due to the difference of refractive index, some light can reflect touch control display.Optics binding technology is adopted touch-screen and liquid crystal display to be combined by optical cement, extraneous light is after injecting touch control display, the light of small part is only had to reflect, when the brightness of liquid crystal display is certain, above can improve the external contrast of touch control display largely, strengthen visual effect.
Optical cement (cementing of optical elements glue) is a kind of close with the optical property of optical element, and has the polymer substance of excellent bonding property.It can be the optical module that can meet light path design requirement two or more cementing of optical elements, also often utilizes it to realize the gummed to cover glasses such as high-precision optical scale, light filters in actual production process.The quality of optical instrument image quality and usability, closely related with the quality and performance of optical cement.This type of optical cement have water white transparency, light transmission rate more than 90%, feature that consolidation strength is good, can solidify under room temperature or middle temperature, and cure shrinkage is little.Organic silica gel, acrylic type resin and unsaturated polyester (UP), polyurethane, the tackifier such as epoxy resin all can cementing optical element, the principal ingredient of optical cement of the present invention is organic silica gel, acrylic type resin, unsaturated polyester (UP) and polyurethane, and organic silica gel accounts for 20% of total deal, acrylic type resin accounts for 30% of total deal, 10% and polyurethane that unsaturated polyester (UP) accounts for total deal account for 40% of total deal, empirical tests, such optical cement of deal formulated in combination and the perfect index match of touch-screen, make the extraneous light entering touch control display after touch-screen, directly through optical cement, the trend of light does not change and good visual effect, there is good user experience.
Usually some treating agents will be added, as catalyzer and rigidizer, to improve its optical property or to reduce cure shrinkage when preparing optical cement.Catalyzer and rigidizer also can change simultaneously in induced chemical reaction, under the immovable situation of chemical reactant, chemical reaction is made to accelerate, or at a lower temperature, via only needing the path of less energy of activation to carry out chemical reaction, namely, under the environment having catalyzer, molecule only needs less energy to carry out chemical reaction.Rigidizer is generally preferably enclosed type hexafluoro antimonate (cationic latent curing agent) and imidazoles and isocyanate condensate, both effects used in combination more, and the content of rigidizer accounts for the 3%-5% of optical cement total amount, catalyzer is preferably zinc octoate, and content accounts for the 4%-6% of optical cement total amount, the proportioning of rigidizer and catalyzer can reach the preparation effect of good optical cement through test, in actual fabrication process, be-0.08MPa ~-0.04MPa by potpourri in vacuum tightness, temperature is stir 1h ~ 2h with the speed of 200 turns/min ~ 800 turn/min under the environment of 25 DEG C ~ 30 DEG C, products obtained therefrom filters through negative pressure reverse percolating filter again, and point be filled in specified containers, finally by the deaeration of high speed defoamer, namely optical cement obtained required for the present invention.
S3: improve system temperature, carry out sclerosis and reinforce reaction, the lower surface of touch-screen is bonded on the polaroid of liquid crystal display front surface by optical cement.Owing to the addition of rigidizer and catalyzer in optical cement, catalyst content increase effectively can reduce sclerosis and reinforce the energy of activation energy needed for reacting, chemical reaction is made to carry out under lower temperature environment, make reacting the initial stage of carrying out, under identical temperature spot, catalyst content is more not only has higher conversion ratio, also can obtain reaction rate faster simultaneously.So add catalyzer and the rigidizer of predetermined quality in optical cement, in ultraviolet irradiation reinforcement effect process, the laminating process of touch-screen and liquid crystal display can be made more quick, and laminating efficiency is high, does not leak glue.
S4: at the upper surface coated with antireflection film of touch-screen.Antireflecting film can reduce the reflection of light, and when extraneous light is very strong, the use of antireflecting film can make most light not reflect, but directly injects touch-screen inside.Antireflecting film is also anti-reflection film, AR antireflecting film, is a kind of surface optics coating, and it passes through to reduce the reflection of light thus the transmitance of increase light.It can improve contrast by the scattered light in minimizing system, such as telescope, and this is very important to uranology.A lot of coating all comprises the different transparent membrane structure of refractive index.The thickness of film determines the reflected light wavelength of its effect.When light produces secondary reflection on anti-reflection film, meeting and former reflected light interfere, thus diminished reflex light.And according to energy conservation, the energy of light is constant.Therefore, when reflected light reduces, transmitted light just increases.Need wavelength be determined during general selection anti-reflection film, as infrared ray, visible ray and ultraviolet.When light dredges the close material of material directive light from light, reflected light has half-wave loss, after plating AR antireflecting film on the touchscreen, the reflected light of touch screen surface differs half wavelength just than the optical path difference of plated film front-reflection light, the reflected light on former and later two surfaces of film disappears mutually, is namely equivalent to the energy adding transmitted light.And can by touch-screen two sides simultaneously plated film allow two of glass faces reduce reflecting effect simultaneously.
Because what plating AR antireflecting film adopted is magnetron sputtering technology, the material sputtered is all the transparent optical film system that the atomic motion of Nano grade is formed.On the performance not impact of touch-screen itself, and also have stiffened effect, be a protection to touch-screen itself, adhesion is extremely strong.Can be considered as having defined an entirety with touch-screen.Magnetron sputtering method is wherein a kind of method of vacuum sputtering coating, normally complete in magnetron sputtering coater, plated film substrate is loaded in Vacuum Deposition machine, with vacuum pump evacuation, Coating Materials (i.e. target) heating is dissolved and flashed to gaseous state, gaseous state target particulate is at the film substrate surface deposition of movement, namely one deck metallic target sheet material layers of light is continuously formed through cooling reduction, conventional target is gold, silver, copper, zinc, chromium, aluminium etc., be preferably aluminium, and the thickness of antireflecting film is preferably 0.08-0.09 μm, the anti-reflection effect of the antireflecting film of this thickness is more outstanding.
In actual production process, for reaching different effects, can on any surface of touch-screen or two sides coated with antireflection film simultaneously, if on the two sides of touch-screen all coated with antireflection films, then before positioning touch screen and liquid crystal display, first plate in the touch screen surface of optical cement to be coated and penetrate one deck antireflecting film.The design of double layer antireflection coating can make the reflecting effect of light better, is more conducive to improving visual effect.
The method for making 1 of this kind of touch control display combines optical cement and antireflecting film, the double action of bi-material, makes the reflectivity of extraneous light only have 0.4%, reduces the reflection of light to external world largely.
Because people is generally in the left and right of 555nm wavelength in the visual range of visible ray.Such as, one piece of common sight glass transmitance when this wavelength only has 91.5 ﹪, and the transmitance of sight glass when this wavelength that antireflecting film has been penetrated in one piece of plating has 99 ﹪, Here it is, and why when seeing the display of profit eye glass vision panel, we can think that color is more bright-coloured, and color is more true to nature.
Refer to Fig. 2, second embodiment of the invention touch control display 2 comprises touch-screen 22, liquid crystal display 24 and framework 25, injection optics glue in the gap of touch-screen 22 and liquid crystal display 24, form an optical cement layer 23, the lower surface of touch-screen 22 is bonded together by the polaroid of optical cement and liquid crystal display 24 front surface, plates one deck antireflecting film 21 at the upper surface of touch-screen 22.
When extraneous incident light arrives antireflecting film 21 surface, because antireflecting film 21 reflecting effect is poor, so only have the light of fraction to reflect, it is inner that most light can inject touch control display 2, the interface of touch-screen 22 and optical cement layer 23 is arrived after touch-screen 22, because touch-screen 22 is identical with the refractive index of optical cement layer 23, be all 1.49, so light can not reflect through touch-screen 22 and optical cement layer 23 interface, but do not change and formerly directively directly inject inside, arrive the interface of optical cement layer 23 and liquid crystal display 24, in the generating portion reflection again of this interface, the reflectivity of whole touch control display 2 light to external world can be reduced to 0.4%.
Darker owing to entering touch control display 2 inside, the energy of light is more weak, so the light of reflection is fewer, the light that last whole touch control display 2 reflects is few more a lot of than not having the situation of antireflecting film 21 and optical cement layer 23.The light luminance reflected is little, the lumen difference that the light that liquid crystal display 24 itself is launched arrives the outermost brightness of touch control display 2 and reflected light diminishes, so the impact of extraneous light on touch control display 2 diminishes, user can see the content that liquid crystal display 24 shows better more clearly, readabilityly 400% can be reached under improving daylight, improve impact resistance up to 300%, user experience is improved largely.The introducing of optical cement layer 23 also can avoid moisture to enter formation water smoke, can also increase the shock resistance of screen, reduces the probability destroyed, even broken, also can not fall down fragment hurt sb.'s feelings because optics is bonding.
Compared with prior art, the method for making 1 of touch control display of the present invention by increasing optical cement layer 23 between liquid crystal display 24 and touch-screen 22, and antireflecting film 21 is penetrated in plating on the top layer of touch-screen 22, under the irradiation of extraneous high light, antireflecting film 21 can reduce the reflection arriving outer touch-screen 22 light, it is inner that most light enters into touch control display 2, because optical cement layer 23 is identical with the refractive index of touch-screen 22, be all 1.49, so light can not reflect at the interface of touch-screen 22 and optical cement layer 23, but continue to advance by former direction, compare with conventional art, just decrease the reflection of light, make final reflected light more weak, when touch control display 2 internal illumination intensity is certain, weakening of ambient light line reflection light, just reduce the diversity factor with display interior light, extraneous light is made to be unlikely the illumination effect having influence on touch control display 2 internal light, thus improve the visibility of touch control display 2.Touch control display 2 sets gradually antireflecting film 21 from outside to inside, touch-screen 22, optical cement layer 23 and liquid crystal display 24, antireflecting film 21 reflecting effect is poor, touch-screen 22 is identical with the refractive index of optical cement layer 23, light is when directive this kind of touch control display 2, and the light be finally reflected is few more a lot of than not having the situation of antireflecting film 21 and optical cement layer 23.The light luminance reflected is little, the lumen difference that the light that liquid crystal display 24 itself is launched arrives the outermost brightness of touch control display 2 and reflected light diminishes, so the impact of extraneous light on touch control display 2 diminishes, user can see the content that liquid crystal display 24 shows better more clearly, improves user's usage degree.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
