Description

The manufacture method of LCD
Technical field
The present invention relates to a kind of manufacture method of LCD.
Background technology
At present, 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.As shown in Figure 1, 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.
The general preparation process of above-mentioned display device is: seal the coating of frame glue on the conductive layer of the array base palte side that contains a plurality of display device figures, under the liquid crystal drop, then two substrates are fitted, cut then, obtain attaching Polarizer behind the individual monitor spare, be assembled into display at last.
Array base palte is easy to be subjected to from the external static electrification lotus in this production run, and these static charges will produce to puncture and destroy the thin film transistor (TFT) on the display device, cause the damage of display device.As shown in Figure 2, therefore the protection loop can be set on the display device on the array base palte, and the protection loop of these display devices can be connected together (as shown in Figure 3) finally by the outer conducting layer figure of display device.When receiving on the display device from the external static electrification lotus, by these loops, make static charge can be distributed to rapidly on the whole array base palte, reduce electrostatic potential, reduce the destruction of static charge to display device.
In the manufacturing and use of actual product, because the area of these conducting layer figures is less, and distance is longer, resistance between distance two ends far away is bigger, being not suitable for electric charge shifts fast, therefore when accumulating the too much situation of static charge on the more or array base palte when external electrostatic charge, still can cause electrostatic breakdown to display device.
Though the protection loop can be set on the display device on the array base palte; but in the manufacturing and use of actual product; because the area of these conducting layer figures is less; and distance is longer; resistance between distance two ends far away is bigger; therefore be not suitable for electric charge and shift rapidly, when accumulating the too much situation of static charge on the more or array base palte when external electrostatic charge, still can cause electrostatic breakdown display device.
