Description
Technical field
The present invention relates to the flat-panel screens field, particularly relate to a kind of display panels and method for repairing and mending thereof of repairing the defective of data line.
Background technology
LCD (LCD, liquid Crystal Display) is a kind of flat-panel screens that is widely used at present, have features such as low consumption electric power, slim light weight and low voltage drive, its displaying principle is to utilize the material behavior of liquid crystal molecule, the ordered state of liquid crystal molecule is changed, cause liquid crystal material to produce various photoelectric effect.Generally speaking, the viewing area of LCD comprises a plurality of pixel regions, each pixel region is meant the rectangular area that is made of two sweep traces (scan line) and two data lines (date line), be provided with thin film transistor (TFT) (TFT in it, thin film transistor) and a pixel electrode, this thin film transistor (TFT) is a kind of switch module (switching device).
Sweep trace and data line mainly are to be used to provide signal of video signal to drive pixel electrode, but influences such as the height fluctuating of polar board surface, thermal treatment, etching manufacturing process during for fear of making, sweep trace and data line are easy to break, and then cause opening circuit (open circuit) or the phenomenon of short circuit (shortci rcuit).And, when the enlarged areas of LCD panel and when improving resolution, need more sweep trace of production quantity and data line, and live width becoming narrower, the manufacturing process degree of difficulty improves like this, causes opening circuit or short circuit phenomenon easilier.
See also Fig. 1, be the existing LCD faceplate part structural scheme of mechanism of repairing the defective of data line.The sweep trace 12 that includes many horizontal expansions on the LCD substrate 10, a plurality of gate pads 14 are arranged at an end of each bar sweep trace 12 respectively, the data line 16 of many longitudinal extensions, a plurality of data pads 18 are arranged at an end of each bar data line 16 respectively, and the viewing area 20 of a plurality of arranged.The unit of viewing area 20 is made of two gate lines 12 and two data line 16 square crossings, and the unit of viewing area 20 is provided with a pixel electrode 22.Substrate 10 also includes many boost line 24A, 24B, 24C, is positioned at viewing area 20 non-display area on every side, and boost line 24A, 24B, 24C cross over the two ends of each bar data line 16.
For instance, when forming an opening A when data line 16A generation broken string, signal of video signal by data line 16A can't arrive opening A place, then can utilize laser or other technologies, data line 16A is produced with point of crossing 26a, the 26b of boost line 24A to be electrically connected, and boost line 24A is cut off at point of contact 28a, 28b according to the shortest selected path, like this, the signal of video signal that is sent to data line 16A just can provide via boost line 24A.But, when signal of video signal passes through the plotted point of boost line 24A and other data lines 16A, the signal of video signal distortion is worsened, particularly when data line 16 numbers are numerous, the number of the plotted point on the boost line 24A also can correspondingly increase, and then the situation of signal of video signal deterioration can be more serious.From the above, repair a data line 16 and just need to expend a boost line 24A, therefore, quantity increase along with boost line 24, the narrowed width of sweep trace 12 and data line 16, resistance value and capacitance that boost line 24 is produced will increase, and this will make that influencing the signal transmission delay time increases, and influences the display quality of LCD.In addition, the quantity of boost line 24 can be subjected to the restriction of LCD panel space and area, and therefore repairable broken string number is quite limited.
At present, prior art is to adopt the mode that patch cord is set that contiguous data line is repaired.Consult Fig. 2, be the existing LCD faceplate part structural representation of repairing the defective of data line.Data line 21, sweep trace 24, and pixel electrode 28 form an independent sub-pixel, patch cord 22 is arranged near the data line 21.Connecting line 23a and 23b and data line 21 laps are provided with repairs some 2C and 2D, carries out laser welding to repairing some 2C and 2D, can make data line 21 keep being electrically connected with patch cord 22, walks around the broken string end points 2A at broken string place and 2B and forms the electrical connection loop.
Fig. 3 is the cross-sectional view along Fig. 2 tangent line V-V.First insulation course 111 is set on the patch cord 22.Above first insulation course 111 data line 21 is set, is provided with above the data line 21 on second insulation course, 110, the second insulation courses 110 pixel electrode 28 is set.Pixel electrode 28 does not cover patch cord 22.
Because of pixel electrode 28 does not hide patch cord 22, this causes patch cord 22 light leaks easily and influences the display quality of LCD panel.Therefore, larger area black matrix" (blackmatrix) must be set on color membrane substrates,, shelter from patch cord 22 so that when color membrane substrates combines with array base palte.But the larger area black matrix" is set on color membrane substrates the aperture opening ratio of LCD panel is reduced, and then influence the display effect of LCD panel.
And, in color membrane substrates combines process with pixel substrate,, so just cause the black matrix" on the color membrane substrates to fail to cover fully patch cord 22 easily because of two substrates of operate miss can produce relative must a dislocation, and the generation light leakage phenomena influences the display effect of LCD panel.
