Embodiment
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to a kind of embodiment of liquid crystal indicator proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
Embodiment one
The schematic top plan view of a kind of liquid crystal indicator that Fig. 2 a provides for the embodiment of the present invention one, the diagrammatic cross-section along B-B ' in Fig. 2 a of a kind of liquid crystal indicator that Fig. 2 b provides for the embodiment of the present invention one.As shown in Fig. 2 a and Fig. 2 b, a kind of liquid crystal indicator that the present embodiment provides, mainly comprises:
First substrate 210, second substrate 220, black matrix" 230 and sealed plastic box 240.
Wherein, the non-display area 251 of first substrate 210 is provided with black matrix" 230, and black matrix" 230 is arranged around edge, viewing area 252, and black matrix" 230 arranged outside has sealed plastic box 240; Wherein sealed plastic box 240 is for encapsulated liquid crystal 260 (see Fig. 2 b), and prevents non-display area 251 light leak, avoids the picture to viewing area 252 shows to cause interference.First substrate 210 and second substrate 220 are oppositely arranged, and black matrix" 230 and sealed plastic box 240 are arranged between first substrate 210 and second substrate 220.
Concrete, first substrate 210 and second substrate 220 can be color membrane substrates and array base palte respectively.
The liquid crystal indicator that the embodiment of the present invention provides is by being arranged on the outside of black matrix" 230 by sealed plastic box 240, sealed plastic box 240 is while encapsulated liquid crystal 260, the effect preventing non-display area 251 light leak can also be played, in case cause interference to during 252 display frame of viewing area.Because sealed plastic box 240 is positioned at the outside of black matrix" 230, so UV-irradiation can be carried out in first substrate 210 side to sealed plastic box 240, or carrying out UV-irradiation to sealed plastic box 240 in first substrate 210 side and second substrate 220 side makes sealed plastic box 240 harden simultaneously, accelerate the setting rate of sealed plastic box 240.The benefit of such setting is, can avoid carrying out from array base palte 140 side in prior art UV-irradiation to sealed plastic box 240 harden easily cause sealed plastic box 240 because circuit array base palte 140 blocks problem that is not illuminated thus that do not harden completely, and the image display quality difference caused thus and the low problem of product percent of pass.
Compared with sealed plastic box 240 is arranged between black matrix" 230 with second substrate 220 with prior art by the outside simultaneously sealed plastic box 240 being arranged on black matrix" 230, the height in sealed plastic box 240 cross section becomes large, when realizing narrow frame liquid crystal display device in prior art, require to reduce to the coatability of the board of coating sealed plastic box 240, reduce production cost.
Preferably, on the basis of above-described embodiment, sealed plastic box 240 can be illumination Post RDBMS and present the colloid of black.Exemplary, sealed plastic box can adopt UV-9508 to solidify glue, adopts UV-irradiation simultaneously, it is fast that this colloid has curing rate under the irradiation of ultraviolet light, the advantage of strong adhesion after solidification, owing to being black after this sealed plastic box ultraviolet light polymerization, so light leakage is effective.
Embodiment two
The diagrammatic cross-section of a kind of liquid crystal indicator that Fig. 3 provides for the embodiment of the present invention two.As shown in Figure 3, the liquid crystal indicator that the present embodiment provides mainly comprises:
First substrate 210, second substrate 220, black matrix" 230 and sealed plastic box 240.
Wherein, black matrix" 230 is positioned at non-display area, and arranges (not shown) around edge of display area, and black matrix" 230 arranged outside has sealed plastic box 240; Wherein sealed plastic box 240 is for encapsulated liquid crystal 260, and prevents non-display area light leak.
With above-described embodiment unlike, the liquid crystal indicator that the present embodiment provides, also comprises: barricade 280.
Wherein, barricade 280 can be arranged on black matrix" 230 towards on the direction of second substrate 220, contact with liquid crystal 260 when unhardened for preventing sealed plastic box 240, in order to avoid composition in sealed plastic box 240 and liquid crystal 260 react, thus harmful effect is caused to the picture display of liquid crystal indicator.
Optionally, barricade 280 can be combined to form between liquid crystal 260 box at first substrate 210 and second substrate 220 to be arranged on black matrix" 230, the distance of distance second substrate 220 preferably can be 0.1 ~ 0.5 micron, prevent the sealed plastic box 240 of the glue when sealed plastic box 240 is unhardened from contacting with liquid crystal 260 better, liquid crystal 260 is polluted.
Preferably, barricade 280 is resin material layer, and the benefit arranged like this to make barricade 280 have certain toughness, in case cause damage to second substrate 220 in liquid crystal indicator manufacturing process.
Further, as shown in Figure 4, in above-described embodiment, liquid crystal indicator can also comprise: wire netting compartment 290.Wire netting compartment 290 can be between second substrate 220 and sealed plastic box 240 and be in non-display area 251, the benefit of such design is, the resistance of wire netting compartment 290 is little, good conductivity, so adopt wire netting compartment 290 can reduce power consumption as electrode at non-display area 251, save the energy and reduce quantity of heat production.
Different from sealed plastic box in the embodiment of the present invention one, in the embodiment of the present invention two, can also by comprising the mode of alloy in sealed plastic box, also sealed plastic box can be set to black, play the effect preventing liquid crystal indicator light leak, now, comparatively wide compared with the selection face of material for envelope frame, the base material of such as sealed plastic box can be common epoxy resin.Alloy wherein in sealed plastic box can have various ways.Can be such as be evenly distributed in foreign particle in sealed plastic box.This foreign particle diameter be 0.01 ~ 5 micron.The benefit of such setting is, can make when sealed plastic box carries out UV-irradiation, the diameter due to alloy is less than the wavelength of ultraviolet light, makes ultraviolet light produce diffraction at alloy place, described sealed plastic box is solidified more fully; Meanwhile, the effect that foreign particle can also play support is exemplary, and above-mentioned foreign particle can be silica dioxide granule or titanium dioxide granule.
In addition, above-mentioned alloy can also be photochromic rear light tight material, and preferably, its optical density≤3, as silver bromide, silver chloride or silver iodide, illustrate for silver bromide below, but be not limited thereto.Silver bromide can resolve into silver and bromine under certain condition, can make the sealed plastic box colour-darkening containing silver bromide, even become black, equally also can reach the technique effect preventing liquid crystal indicator light leak after reaction.
It should be noted that, liquid crystal indicator described in above-mentioned all embodiments can refer to that such as mobile phone, panel computer and LCD TV etc. have the device of Presentation Function, do not do concrete restriction at this.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
