Description
Technical field
The present invention relates to a kind of liquid crystal indicator, particularly relate to and a kind ofly can improve remediation efficiency, prevent the mutual short circuit of data wire and common electrode, and short circuit partly can be isolated liquid crystal indicator and the restorative procedure that re-starts reparation.
Background technology
Traditional cathode-ray tube (CRT) display relies on the phosphor powder on the cathode-ray tube electron emission bump screen to show image, but the principle of liquid crystal display is then fully different.Usually, liquid crystal display (LCD) device comprises that one has the color membrane substrates and the array basal plate of color film, between upper strata Polarizer and lower floor's Polarizer, the each interval certain distance and mutually over against, also be with a circle envelope frame glue between these two substrates, liquid crystal by this envelope frame glue binder between these two substrates.This array base palte has many data lines, a plurality of corresponding data line terminal and a plurality of reparation line and draws crimp type terminal.Be formed on these two substrates a plurality of electrodes also mutually over against, voltage is applied on the liquid crystal by the electrode on the substrate, thus the arrangement that changes liquid crystal molecule according to the voltage that acts on then shows image.Because liquid crystal indicator utilizing emitted light not itself, it needs light source to show image again, and therefore, liquid crystal indicator also has the backlight that is positioned at the liquid crystal panel back, to show image according to the arrangement control of liquid crystal molecule from the light quantity of backlight incident.The light that backlight sends becomes the polarized light with certain polarization direction through lower floor's Polarizer.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 Polarizer, 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 just different.The combination of the different light intensity by three kinds of colors of RGB shows motley image.
In the manufacture process of actual product, the bad overall bad very big proportion that accounted for breaks.In order to improve the yield of production, normally bad lead is repaired.In the array processes process, can repair broken string by the mode of chemical vapor deposition (CVD) reparation, then can't adopt the method for the semi-manufacture behind the one-tenth box, the broken string of finding behind the one-tenth box is bad usually all handles as defective products, has increased the weight of cost burden.Repair line technology has then been adopted in the reparation of at present product behind the one-tenth box being carried out, and by repair line the data wire of display screen inside is repaired, thereby is reached the purpose that improves yield rate.Usually the repair wire structure that adopts as shown in Figure 1, when a data wire or gate line 3 generation broken string, in portion of terminal with laser with a repair line 2 and this data wire or gate line 3 welding conductings, at the offside of portion of terminal with laser with repair line bus 1 and this data wire or gate line 3 welding conductings, postback living this data wire that breaks or the other end of gate line 3 so that this repair line signal is drawn again, wherein this repair line 2 of portion of terminal is positioned at the inboard of 101 regions of sealed plastic box.Figure 2 shows that the partial enlarged drawing of portion of terminal, the data line or the gate line 3 of broken string wherein takes place and repair line signal wire 6 in weld 15 laser welding conducting.Figure 3 shows that the fundamental diagram of repairing line circuit, introduce the reparation line circuit in portion of terminal by broken string will take place laser welding point 104 the data line or the signal of gate line 3, then through amplifier 5 and reparation line bus 1, last data line or the gate line welding conducting that will repair line bus 1 and this generation broken string once more by another laser welding point 104 of portion of terminal offside, again signal is drawn back this data line or the other end of gate line 3, to finish reparation.
The various repair wire structures at the inner cabling of screen that adopt in the product at present exist stray capacitance, shortcoming that resistance is big.Cabling and each bar data wire in the portion of terminal repair line are overlapping, and there is overlap capacitance in this part, and there is the parasitic capacitance with the subtend common electrode wire in non-overlapping part, thereby overall capacitance is bigger.In addition, owing to have the generation of static in the technological process, and also cut owing to the external conductive loop after cutting off, thus easier introducing electrostatic breakdown.Adopt the liquid crystal indicator of gold goal transmission current potential mode in the sealed plastic box between gold goal and holding wire, to puncture easily at static after the cut-out and cause short circuit.And common reparation line mode can't be repaired this badness, the synoptic diagram of data line portion of terminal when being data line generation electrostatic breakdown shown in Figure 4, the electrostatic breakdown position 304 of data line is in envelope frame Jiao101Chu, and repair the inboard that line 302 is positioned at 101 regions of envelope frame glue, thereby can't successfully repair.
Summary of the invention
