If the thickness of display device window is greater than restricted portion, the thickness of display device window is bigger so, can not satisfy required ideal thickness.
Below, the manufacture method of the present invention's display device window is described in detail.
A kind of method of making the display device window is characterized in that implementation step is as follows: the UV adhesive is applied on the synthetic resin substrate; Be coated with Locating Glass on the synthetic resin substrate of UV adhesive; Make described synthetic resin substrate and described glass by roll press with the stub area that little by little is pressed into synthetic resin substrate and glass from the initiating terminal zone of synthetic resin substrate and glass to remove gas; And irradiation UV light is to solidify described UV adhesive.
In addition, although without limits, in said method, can before or after the UV irradiation process, comprise having and the heat drying process of the heat drying process same effect of IR (infrared ray) method or the heat drying process of IR (infrared ray) method.
In the manufacture method of display device window according to the present invention, synthetic resin substrate 10 bonds by UV adhesive 20 and is pressed, although the inventor is devoted for years in eliminating the bubble method, does not obtain satisfied effect in the bonding process.Yet, through finding behind the painstaking efforts, when in pressing process, carrying out compacting gradually, rather than when suppressing simultaneously, gas is being discharged from the pressing direction and on the side of pressing direction, and is removed effectively by roll press.
In addition, in the coating process of UV adhesive 20, when using the dispersion coating machine that the part bonded areas is disperseed to be coated with, can more effectively remove bubble, thereby can avoid the phenomenon that UV adhesive 20 outwards overflows in pressing process.
Especially, when the coating weight of UV adhesive 20 when the compacting direction of advance reduces, bubble is more effectively removed, and the phenomenon of outwards overflowing of the more effective UV of avoiding adhesive 20.
In addition, the all or part of cutting of the edges and corners of intersecting with glass 30 bonding planes and side on the synthetic resin substrate 10 and after forming gas discharge section 12, promptly when gas discharge section 12 at synthetic resin substrate 10 or/and form on the glass 30, when suppressing, find to remove described bubble better by gas discharge section 12.Like this, need not the bonding of carrying out, also can effectively remove bubble, thereby significantly improve production efficiency by means of the decompression pressing mode.
Fig. 7 shows the flow chart of manufacture method of the display device window of the one exemplary embodiment according to the present invention.The exemplary display part window that produces according to above-mentioned manufacture method comprises aforementioned display device part window, but is not limited to this.The detailed construction of display device window has provided so that after this need not more describe again.For example, synthetic resin substrate 10 be or/and glass 30 can be formed with gas discharge section 12, and do not carry out any special explanation, and described glass 30 can be positioned described synthetic resin substrate 10 above or below.
Preparation method to the display device window is specifically described below.
At first, synthetic resin substrate 10 or glass 30 can be coated with UV adhesive 20.Method at synthetic resin substrate or coating UV adhesive on glass is not specially limited, and multiple coating process known in the art all can adopt.The preferred use disperseed coating machine bonded this regional part that goes out the bonding surface of glass of painting synthetic resin substrate 10 dispersedly.
Disperse the control of coating machine by controller, thus the drain position and the discharge rate of control adhesive.It can be single or multiple disperseing the outlet of coating machine, disperses the coating time to save.Simultaneously, even under situation about the UV adhesive being coated on the synthetic resin substrate 10, still use above-mentioned UV adhesive coating process.
Fig. 8 and Fig. 9 show a plane, and this plane is presented at the exemplary method of disperseing the coating UV adhesive on the glass substrate.
As shown in Figure 8, when using above-mentioned dispersion coating machine to disperse to be coated with, be preferably in the subregion and be coated with, but not whole zone.More preferably, as shown in Figure 9, the dispersion coating weight of UV adhesive reduces gradually towards the compacting direction of advance.In addition, the dispersion that can carry out as shown in figure 13 is coated with.In other words, the UV adhesive is being coated with when pressing direction is discharged continuously in the zigzag mode dispersedly, and the amount of the UV adhesive that is coated with reduces towards the direction of carrying out compacting.
When a large amount of UV adhesives 20 are discharged from the initial most advanced and sophisticated place of the compacting generation of synthetic resin substrate 10, the amount of the UV adhesive 20 that is discharged from little by little or step by step reduces towards the last tip of synthetic resin substrate 10, bubble can more effectively be removed, and can reduce overflowing of UV adhesive 20 like this.Preferred but non-limiting, as to regulate UV adhesive discharge rate is determined in 0.005 to 0.1mm scope with the thickness after 20 coatings of UV adhesive.
Next, the glass 30 that is coated with UV adhesive 20 is synthesized resin substrate 10 location.Certainly, even the UV adhesive is coated on the synthetic resin substrate 10, glass 30 also can be selectively located on the synthetic resin substrate 10 that is coated with UV adhesive 20.Simultaneously, the both sides of glass 30 and synthetic resin substrate 10 can coating UV adhesive 20.
At this moment, can suppress, only need make the position of bonded areas of glass 30 consistent with the position of the bonded areas of synthetic resin substrate 10.Although do not illustrate in the Figure of description, the crimping initiating terminal can be in the place that synthetic resin substrate 10 contacts with glass 30, and end can keep certain intervals between glass 30 and synthetic resin substrate 10.Preferably, synthetic resin substrate 10 is decorated; More preferably, synthetic resin substrate 10 is forming decorative pattern layer 11 on upper surface or the lower surface at least partly, image display area 1 on the window can not be provided with decorative pattern layer 11, perhaps be decorated transparent or opaque (translucent), when display device is closed, show decorative pattern layer 11; And during opening display, display image then.
Then, use roll press 50, to terminal synthetic resin based plate 10 and glass 30 are progressively carried out crimping, thereby remove gas from initiating terminal.
Figure 10 and Figure 14 show the schematic diagram that utilizes roll press 50 to suppress and remove the operation of gas.
Referring to Figure 10 and Figure 14, glass 30 or synthetic resin substrate 10 can be positioned to travel mechanism 60, and can be suppressed by roll press 50 by aforementioned process.Described roll press 50 can be from initial tip be little by little suppressed described synthetic resin substrate 10 and glass 30 to last tip, so that residual gas is via the side of synthetic resin substrate 10 or glass 30 or terminal and be discharged from and remove, thereby solve the problem that bubble takes place.Roll press 50 can be according to self driving force and self roll extrusion; Perhaps can be when travel mechanism 60 moves, by with the contacting and roll extrusion automatically of synthetic resin substrate 10.Running roller only is formed on the upper surface in the accompanying drawings, but is not limited thereto, and above-mentioned running roller also can be formed on the lower surface.The making material of roller is not limited, and can adopt metal, plastics or rubber; The preferred elastomeric material that adopts stops the damage that brings to product.The pressure of roll-type briquetting press 50 does not limit, but for product, particularly glass 30, must apply suitable pressure, to avoid its damage.Endurable pressure can change and whether the material that must depend on glass 30 is that safety glass carries out suitable adjusting.Therefore crucial is suitably to control endurable pressure, and this can be regulated simply by replica test, so omit the detailed description to it.When using this roll press 50, when travel mechanism 60 is moved, suppress and remove the operation of gas, carry out subsequent processing thereupon, therefore, compare traditional process, significantly shortened the process time.
Then, irradiation ultraviolet radiation is with the UV curing adhesive, thereby produces the display device window.The UV illuminating method is not limited.For example, can adopt traditional UV illuminating method.The UV adhesive that contains light trigger (photo initiator) can be accelerated curing reaction.Do not limit the time of described UV irradiation especially.For example, because synthetic resin substrate 10 is extremely thin, therefore several seconds all is suitable to a few minutes.
Simultaneously, described method also can be included in the IR heat drying process before or after the UV irradiation or possess the heat drying process of same effect with described IR heat drying process.
