Traditional CRT monitor relies on the fluorescent powder on the cathode-ray tube (CRT) emitting electrons bump screen to come display image, but the principle of liquid crystal display is then different fully.Usually, liquid crystal display (LCD) device has upper substrate and infrabasal plate, have each other certain intervals and mutually over against.Be formed on two substrates a plurality of electrodes each other over against.Liquid crystal is clipped between upper substrate and the infrabasal plate.Voltage is applied on the liquid crystal through the electrode on the substrate, thus then according to the voltage that acted on change the arrangement display image of liquid crystal molecule, because liquid crystal indicator is not launched light as stated, it needs light source to come display image.Therefore, liquid crystal indicator has the backlight that is positioned at the liquid crystal panel back.Thereby the arrangement according to liquid crystal molecule is controlled from backlight quantity of incident light display image.As shown in Figure 1, between two Polarizers, accompany glass substrate, colored filter (color film), electrode, liquid crystal layer and thin film transistor (TFT), liquid crystal molecule is the material with refractive index and dielectric constant anisotropy.The light that backlight sends becomes the polarized light with certain polarization direction through lower floor's Polarizer.Institute's making alive between the thin film transistor (TFT) control electrode; And this voltage acts on the polarization direction that liquid crystal is controlled polarized light; Polarized light forms monochromatic polarized light after seeing through corresponding color film chromatograph, if polarized light can penetrate the upper strata Polarizer, then demonstrates corresponding color; Electric field intensity is different, and the deflection angle of liquid crystal molecule is also different, and the light intensity that sees through is different, and the brightness of demonstration is also different.The combination of the different light intensity through three kinds of colors of RGB shows motley image.
Liquid crystal panel is made flow process, makes color membrane substrates and array base palte, coating one circle envelope frame glue on color membrane substrates or array base palte; Use the liquid crystal dripping device an amount of liquid crystal that in the zone that envelope frame glue surrounds, drips; In vacuum environment, another piece substrate is fitted with it, use UV-irradiation and thermmohardening to make envelope frame glue sclerosis fixing (envelope frame gum forming), prevent that color membrane substrates and array base palte from because of receiving external force the skew dislocation taking place; And causing the decline of aligning accuracy, influence shows.Fig. 2 is the floor map of display panels.
As shown in Figure 3, by ultraviolet light (UV) from the top through the open region on the UV mask (UV MASK) after the substrate of irradiation after fitting.Dual mode is generally arranged, a kind of be color membrane substrates at upside, array base palte is at downside; A kind of be array base palte at upside, color membrane substrates is at downside.
Thin film transistor (TFT) in the viewing area (TFT), when receiving UV-irradiation, the free electron in the amorphous silicon will absorb luminous energy, transition take place and flow to form electric current, destroy the TFT switching characteristic, and influence shows.Therefore shade---UV mask plate carries out shading to need use.As shown in Figure 4, only at the regional opening of correspondence envelope frame glue pattern, other places cover to avoid the UV light transmission to shine on the thin film transistor (TFT) in the viewing area with shading films such as metals the UV mask.
Envelope frame glue becomes circular-arc lines when being coated with in the bight; Because when being coated with in the bight; Nozzle has the turning of one 90 degree, and speed can descend slightly, and the arc position of the envelope frame glue in bight can squint along about the line of design centre; The width of envelope frame glue is general general about 0.4mm during coating; Developed width after envelope frame glue after last array base palte and color membrane substrates are fitted extends is about 1.5mm, and UV mask light shielding part is generally from about the edge 0.4mm of envelope frame glue, so the skew of envelope frame glue is excessive when the bight coating takes place in regular meeting; The inboard situation (as shown in Figure 5) of UV mask light shielding part is gone in position after envelope frame glue after causing array base palte and color membrane substrates to be fitted extends; Or go to the outer situation (not shown) of contour substrate line, and the former is prone to take place the reliability problem of the bad envelope frame glue stain liquid crystal that causes of sclerosis, and substrate takes place and cuts off bad problem in latter Ze Yi.
Summary of the invention
Goal of the invention: to the problem and shortage of above-mentioned prior art existence; The purpose of this invention is to provide a kind of liquid crystal indicator; Avoid having significantly reduced the bad problems of demonstration such as image retention that cause owing to liquid crystal is contaminated owing to the bight envelope frame glue pattern after fitting exceeds the bad envelope frame glue stain liquid crystal that causes of sclerosis that UV mask open region causes.
Technical scheme: for realizing the foregoing invention purpose; The technical scheme that the present invention adopts is a kind of liquid crystal indicator; Comprise the array base palte and the color membrane substrates that are oppositely arranged; On said array base palte or color membrane substrates, scribble envelope frame glue, one circular-arc thrust figure is set respectively, be used for limiting the shape and the position of bight envelope frame glue pattern in the envelope frame glue dispensing area both sides in liquid crystal display four bights.
Width after the inboard spacing of said thrust figure can extend more than or equal to the envelope frame glue after array base palte and the color membrane substrates applying.
Central lines when the center line of the inboard spacing of said thrust figure can design with the coating of envelope frame glue.
Said thrust figure can form in the color membrane substrates side, can form in the lump when on color membrane substrates, forming red/green/indigo plant/post layer pattern.
The box that the height of said thrust figure can be slightly less than liquid crystal cell is thick, here the thick distance that refers between color membrane substrates and the array base palte of the box of liquid crystal cell.
The width of said thrust figure can be between 20um to 500um.
Beneficial effect: the present invention is through being provided with the circular-arc thrust figure of a determining deviation respectively in the envelope frame glue dispensing area both sides in liquid crystal display four bights; Be used for limiting the shape and the position of bight envelope frame glue pattern; To avoid having significantly reduced the bad problems of demonstration such as image retention that cause owing to liquid crystal is contaminated owing to the bight envelope frame glue pattern after fitting exceeds the bad envelope frame glue stain liquid crystal that causes of sclerosis that UV mask open region causes.
