Description
Technical field
The present invention relates to a kind of LCD, refer in particular to the drip LCD of formula injection method of a kind of employing, specifically be meant a kind of LCD with sept.
Background technology
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 mutually over against.Liquid crystal is clipped between upper substrate and the infrabasal plate.Voltage is applied on the liquid crystal by 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 mentioned above, 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.Accompany glass substrate, colored filter, electrode, liquid crystal layer and transistor film between two polaroids, liquid crystal molecule is the material with refractive index and dielectric constant anisotropy.The light process that backlight sends is polaroid down, becomes the polarized light with certain polarization direction.Institute's making alive between the transistor controls 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 polaroid, then demonstrates corresponding color; Electric field intensity difference, the deflection angle of liquid crystal molecule are 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 by three kinds of colors of RGB shows motley image.
Fig. 1 is the floor map of display panels in the prior art.Accompanying drawing 2 is the flat distribution map of liquid crystal drop when dripping liquid crystal in the engineering in the viewing area under the liquid crystal drop in the prior art, as shown in Figure 2, be coated with a circle envelope frame glue on the color membrane substrates 2 or on array base palte 1 as frame 3, frame 3, color membrane substrates 2 and array base palte 1 constitute a sealed space as liquid crystal area 4, and this liquid crystal area 4 is made up of viewing area 5 and the non-display area 6 between viewing area 5 and frame 3; Use the liquid crystal dripping device an amount of liquid crystal that in this viewing area 5, drips then, then in vacuum environment with another piece baseplate-laminating on frame 3, and use UV-irradiation to make frame 3 be subjected to thermmohardening fixed-type, to prevent that color membrane substrates 2 and array base palte 1 from because of being subjected to external force the skew dislocation taking place, and causing the decline of aligning accuracy, influence shows.
Liquid crystal is in the process of dripping, and the liquid crystal drops that just splashed in the viewing area 5 distribute as shown in Figure 2, liquid crystal drop can be on substrate after down slowly diffusion come, form appearance as shown in Figure 3.From under the liquid crystal drop to the viewing area 5 and be diffused into the frame 3 that envelope frame glue makes and need a period of time, when during this period of time if liquid crystal diffused to frame 3 residing positions before frame 3 uncured moulding, dissociant (ion-type impurity) in the frame 3 of uncured moulding still will pollute liquid crystal material, reduce the resistivity of liquid crystal, cause liquid crystal display device to occur showing bad phenomenon, cause problems such as image retention.
Summary of the invention
