Fig. 3 is the schematic top plan view of the single pixel region of the image element array substrates of the liquid crystal indicator of Fig. 2.Please refer to Fig. 3, each pixel region P10 of image element array substrates 1100 is divided into three sub-pixel area P12, P14 and P16.Do not illustrate the black matrix 1400 of Fig. 2 in Fig. 3, and only indicate opening 1402 position of black matrix 1400 with dotted line, opening 1402 exposes a pixel region P10, that is the region outside black matrix 1400 cover gab 1402.Image element array substrates 1100 also has multiple pixel electrode 1112 and multiple pixel electrode 1114, but each pixel region P10 only has a pixel electrode 1112 and a pixel electrode 1114.These pixel electrodes 1112 and 1114 are with regard to the patterned electrode layer 1110 of pie graph 2, that is these pixel electrodes 1112 and 1114 can form by the conductive material of same rete is patterned, but the present invention is not limited to this.
Each pixel electrode 1112 is configured at a sub-pixel area P12, and has a trunk B110, a trunk B120 and multiple branch B130.Trunk B110 and trunk B120 is orthogonal in fact and define four quadrants.With trunk B120 for benchmark, the position angle being positioned at the branch B130 of same quadrant is identical.For example, the position angle of the branch B130 of all quadrants is sequentially 45 degree, 135 degree, 225 degree and 315 degree, but is not limited to this.In other words, the pattern of each pixel electrode 1112 is roughly in M shape.
Each pixel electrode 1114 has a trunk B140, trunk B150, a multiple branch B160, a trunk B170, trunk B180, multiple branch B190 and branch B195.Trunk B140 and trunk B150 is orthogonal in fact, and trunk B170 and trunk B180 is orthogonal in fact, and branch B195 connects trunk B140 and trunk B170.In the present embodiment, trunk B110, B140 and B170 are parallel to each other.Trunk B140 is overlapping with black matrix 1400 (being shown in Fig. 2) and nearby subpixels district P14, trunk B170 are overlapping with black matrix 1400 and nearby subpixels district P16.That is be that it is other that each trunk B140 and B170 is positioned at opening 1402, and each trunk B140 and B170 at least partially or all overlapping with black matrix 1400.Trunk B150 and B160 is positioned at sub-pixel area P14.The branch B160 being positioned at the same side of trunk B150 is parallel to each other in fact.Trunk B180 and B190 is positioned at sub-pixel area P16.The branch B190 being positioned at the same side of trunk B180 is parallel to each other in fact.For example, the angle of trunk B150 and B160 is 45 degree, and the angle of trunk B180 and B190 is 45 degree, but is not limited to this.In other words, trunk B140, B150 and B160 roughly form the pattern as half M shape, and trunk B170, B180 and B190 also roughly form the pattern as half M shape.
Please refer to Fig. 2 and Fig. 3, because each trunk B140 and B170 of pixel electrode 1114 is overlapping with black matrix 1400, therefore liquid crystal indicator 1000 is when display frame, result from dark line that trunk B140 and B170 locates can cover by black matrix 1400, and then promote the brightness of display frame and contrast.
When driving liquid crystal indicator 1000, the driving voltage inputting different size, in pixel electrode 1112 and 1114, drives liquid crystal layer 1300 to produce the electric field of different size.Specifically, the pixel electrode 1112 and 1114 of same pixel region P10 is input identical driving voltage in first sequential, can be there is narrow difference by adjusting with the driving voltage of pixel electrode 1112 in the driving voltage of pixel electrode 1114 in next sequential, and pixel electrode 1112 drives liquid crystal molecule to show same original image signal from 1114 with different driving voltages.Therefore, the liquid crystal molecule of the liquid crystal layer 1300 above the pixel electrode 1112 and 1114 of same pixel region P10 is being had narrow difference by the degree of toppling over after driving.Therefore, user is when single visual angle viewing display frame, in single pixel region P10 can there is narrow difference with the transmittance in region corresponding to pixel electrode 1114 in the transmittance in region corresponding to pixel electrode 1112, and this difference contributes to the problem solving colour cast and the color saturation deficiency that may exist.And, region (i.e. sub-pixel area P14 and P16) corresponding to pixel electrode 1114 surrounds region corresponding to pixel electrode 1112 (i.e. sub-pixel area P12), therefore can promote the fineness of the picture shown by liquid crystal indicator 1000.
In addition, in each pixel region P10, the area allowing the area summation of sub-pixel area P14 and P16 be more than or equal to sub-pixel area P12 can be designed.In addition, also adjustable driving voltage and the liquid crystal layer that the liquid crystal layer 1300 driven is greater than at the transmittance of the part of sub-pixel area P driven at the transmittance of the part of the second sub-pixel area.That is be that, when driving liquid crystal indicator 1000 display frame, in each pixel region P10, the brightness shown by P14 and the P16 of sub-pixel area can be less than the brightness shown by the P12 of sub-pixel area.Certainly, the allocation scheme of clear zone and dark space and area ratio also can be different from aforesaid way.Moreover in single pixel region P10, the driving voltage being input into pixel electrode 1112 and 1114 is good with identical polar, but is not limited to this.It should be noted, the design of the present embodiment allows the driving voltage of the pixel electrode 1112 and 1114 of same pixel region P10 produce narrow difference in adjacent two sequential, but also directly can directly input different driving voltages in two pixel electrodes of same pixel region in same sequential in other embodiments.
Referring again to Fig. 3, image element array substrates 1100 can have more in multi-strip scanning line 1130, a plurality of data lines 1140 and multiple active component 1150 and 1160, Fig. 3 and only illustrate two sweep traces, 1130, data line, 1140, active component 1150 and an active component 1160.Sweep trace 1130 is crossing with data line 1140 and roughly define pixel region P10.Image element array substrates 1100 is more configured with shared distribution 1170.Active component 1150 and 1160 is electrically connected pixel electrode 1112 and 1114 respectively.In addition, image element array substrates 1100 also can comprise active component 1180, and active component 1180 is electrically connected pixel electrode 1114.The active component 1150 and 1180 that each pixel electrode 1114 is electrically connected is driven by two sweep traces 1130 respectively.Therefore, in first sequential, sweep trace 1130 opens the active component 1150 and 1160 be connected with 1114 with the pixel electrode 1112 of same pixel region P10, and identical voltage signal then writes this two pixel electrodes 1112 and 1114 by data line 1140.In next sequential, next sweep trace 1130 opens the active component 1180 be connected with pixel electrode 1114, make the voltage generation pressure drop of the pixel electrode 1114 writing identical voltage signal in last sequential with pixel electrode 1112, and then make in this sequential, to drive the voltage of the pixel electrode 1112 and 1114 in single pixel region P10 to produce narrow difference.The said structure and method making the voltage of driving pixel electrode 1112 and 1114 produce narrow difference is only and illustrates, but the present invention is not limited to this.
In sum, in image element array substrates of the present invention, liquid crystal indicator and driving method thereof, because half M shape pixel electrode of both sides can cause the part of dark line overlapping with black matrix, therefore can avoid the generation of dark line and promote brightness and contrast.In addition, surrounded the design of the pixel electrode of another M shape by the part of two and half M shapes of a pixel electrode, the fineness of picture can be promoted.
