Description
Technical field
The present invention relates to a kind of display panels, particularly relate to a kind of display panels with visible cutting precision mark.
Background technology
Have low power consumption and characteristic such as be convenient for carrying based on LCD, LCD more and more receives an acclaim.Generally speaking, LCD has display panels and module two parts backlight.Display panels comprises that mainly a bottom substrate, a head substrate and are arranged at the liquid crystal material between the two substrates, wherein have a plurality of thin film transistor (TFT)s on the bottom substrate, it is commonly referred to as " array base palte (array substrate) ", and head substrate has a colored filter, is commonly referred to as " colored optical filtering substrates (filter substrate) ".Display panels is that the optical anisotropy (optical anisotropy) that utilizes liquid crystal material and polarization characteristic are with show image.Because active-matrix type display panels (active matrix liquid crystal display panel) has high-res and the superiority on video display, it has become one of most popular sci-tech product now.
Many data lines that receive many gate lines of scanning signal and receive data signals are formed on the array base palte, to define a plurality of pixel regions.A pixel electrode that is connected to a thin film transistor (TFT) is formed on each pixel region, gives the liquid crystal material with supply voltage.Colored filter on the colored optical filtering substrates corresponds to these pixel regions on the array base palte, and this colored filter has a plurality of red, green and blue (little) optical filters.One black matrix" (black matrix) is formed on the colored filter, with the light of blocking-up pixel electrode area with exterior domain, prevents that irradiate light is to thin film transistor (TFT).Colored optical filtering substrates more comprises community electrode, gives the liquid crystal material with supply voltage.
Common electrode and pixel electrode are respectively formed on colored optical filtering substrates and the array base palte opposed inside surface, and liquid crystal material places in the accommodation space between this two inner surface.Form polarization layer at colored optical filtering substrates and array base palte outer side edges, promptly finish the making of liquid crystal cells (liquid crystalcell).Be supplied to the voltage swing of common electrode and pixel electrode by control, the light transmittance of may command liquid crystal cells utilizes optical shutter effect (light-shutter effect) by this, can demonstrate image.
Fig. 1 one has the schematic cross-section of the electronic installation 1 of Presentation Function, and this electronic installation 1 is placed in the housing 2.Electronic installation 1 is provided with a LCD, so that Presentation Function to be provided.For simplifying accompanying drawing, this LCD is only drawn major part, comprises a backlight and a display panels.Display panels comprises two transparency carriers 3,4 and a seal element 5, and a liquid crystal material 6 places between two transparency carriers 3,4.Backlight is located at the display panels below, and this backlight is made up of a backlight 7 and a fluorescent tube 8.Display panels is arranged on the printed circuit board (PCB) 9, and backlight places printed circuit board (PCB) 9 belows.Printed circuit board (PCB) 9 has an opening 10, supplies the light of backlight to pass through, and enters display panels.Housing 2 has the viewing area of a window 11 corresponding display panels.
One of assembling process committed step of electronic installation 1 each parts is that LCD is assembled in the mechanical registeration precision in the housing 2.If LCD can't reach the mechanical registeration precision when being assembled in the housing 2, LCD will come off in housing 2 easily.In view of the requirement of mechanical registeration precision, can when the cutting display panels, dispose a mark by the line of cut intersection usually, for the cutting accuracy of inspecting display panels.Fig. 2 is the display panels floor map before the cutting, and wherein a display panels 21 is produced on the large substrate 20 in advance.Each border of display panels 21 all is provided with a line of cut 22, and is formed with a cross mark 23 in line of cut 22 intersections that intersect in twos.Fig. 2 A is the part enlarged drawing of Fig. 2, after display panels 21 cutting is finished, by measure each bar line of cut 22 and residual cross mark 23 apart from d
1And d
2, to confirm the cutting accuracy of display panels 21.But the design of this kind cutting mark needs measuring operation, makes acknowledging time longer.For exempting Measuring Time, the another kind of practice is that the configuration one size square mark 24 identical with cutting accuracy is in the intersection of the line of cut 22 that intersects in twos, shown in Fig. 2 B.Display panels 21 after cutting, then according to each bar line of cut of visual examination 22 and square mark 24 apart from d
3And d
4Or residual square mark 24, to confirm cutting accuracy.Work as d
3And d
4When leaving remaining square mark 24 on the size of square mark 24 or the display panels 21, cutting accuracy that then can visual judgement display panels 21 is in the scope of allowing.Shown in ginseng Fig. 3 A, yet the design of the square mark 24 that this kind size is identical with cutting accuracy has at the line of cut intersection under the situation of figure 25, and figure 25 can cover in square mark 24, so that after display panels 21 cuttings, have no way of judging cutting accuracy.Therefore, this kind mark design is not suitable for the display panels configuring condition that the line of cut intersection has figure.Again referring to Fig. 3 B, for continuously apart from arrange (be about line of cut or all desire up and down as the viewing area with) the configuration scenario of display panels 21, display panels 21a and 21b after cutting down, though can by visual examination display panels 21a line of cut 22 and square mark 24 apart from d
3And d
4Whether greater than the size of square mark 24, but if according to another display panels 21b line of cut 22 side by side of visual examination and square mark 24 apart from d
5, then in fact and can't judge the cutting accuracy of display panels 21b.Therefore, the design of the square mark 24 of this kind also is unsuitable for continuously apart from the configuration scenario of the display panels of arranging.
In view of the problem that above-mentioned known technology faced, demand providing a kind of situation of cutting mark urgently applicable to various display panels configurations.
