Specifically, first alignment pattern 270 and second alignment pattern 290 can be orientation slit, orientation protrusion or its combination.In addition, first alignment pattern 270 and second alignment pattern 290 can be disposed on the active elements array substrates 210, and can be configured on the subtend substrate 230 or be disposed on both simultaneously.In detail, when first alignment pattern 270 and second alignment pattern 290 during for the orientation slit, first alignment pattern 270 can be the orientation slit that is formed on first pixel electrode 220, and second alignment pattern 290 can be the orientation slit that is formed on second pixel electrode 222.Perhaps, first alignment pattern 270 and second alignment pattern 290 also can be the orientation slits that is formed on the counter electrode 232.In the same manner, when first alignment pattern 270 and second alignment pattern 290 during for the orientation protrusion, first alignment pattern 270 and second alignment pattern 290 can be disposed at active elements array substrates 210 and subtend substrate 230 at least on one of them.In addition, first alignment pattern 270 and second alignment pattern 290 can also be the combinations of orientation slit and orientation protrusion, wherein orientation slit and orientation protrusion can be disposed at active elements array substrates 210 and subtend substrate 230 on one of them, or are disposed at respectively on active elements array substrates 210 and the subtend substrate 230.
Generally speaking, the display panels 200 relevant size design broads on the bearing of trend of sweep trace 212 that show product are to meet the angular field of view of human body.Also therefore, often higher relatively on the market for showing that the angular field of view of product on sweep trace 212 bearing of trends requires, particularly for large scale and wide-screen demonstration product.When display panels 200 showed, the liquid crystal molecule in the liquid crystal layer 250 can be subjected to first alignment pattern 270 and swing to different directions with the influence of second alignment pattern 290, thereby reaches the demonstration effect of wide viewing angle.If can allow the bearing of trend of swinging to convergence sweep trace 212 of liquid crystal molecule, the display view angle scope is further enlarged on this direction, and the probability of colour cast and color saturation deficiency take place when watching in the different visual angles that can reduce that this side up.
Yet, make swinging to of all liquid crystal molecules approach the bearing of trend of sweep trace 212, can make display panels 200 display effect variation in the other direction, even influence the display brightness of display panels 200.Therefore, the present invention proposes configuration first alignment pattern 270 and second alignment pattern 290 in same pixel district P at this.The bearing of trend of first alignment pattern 270 and second alignment pattern 290 intersects with different angles and sweep trace 212 bearing of trends so that the part liquid crystal molecule swing to the bearing of trend that approaches sweep trace 212.Thus, the angular field of view of display panels 200 on sweep trace 212 bearing of trends is comparatively broad, and still can keep good display effect in the other direction.Below will implement the structure that example illustrates display panels of the present invention with several, it is not in order to limit the present invention for explanation for example only.
Fig. 4 is the partial top view of the display panels of one embodiment of the invention, and single pixel cell wherein only is shown.Please refer to Fig. 4, pixel cell 400 electrically connects with sweep trace 402 and data line 404, and pixel cell 400 comprises first active component 406, second active component 408, first pixel electrode 410 and second pixel electrode 420.First active component 406 and first pixel electrode 410 electrically connect, and second active component 408 and 420 electric connections of second pixel electrode.In addition, first active component 406 electrically connects with data line 404 and sweep trace 402, and first active component 406 and second active component, 408 electric property couplings.
In the pixel cell 400, connect first active component 406 of sweep trace 402 and data line 404 and the switch that second active component 408 is respectively control first pixel electrode 410 and second pixel electrode 420.First pixel electrode 410 and second pixel electrode 420 define the first viewing area D1 and the second viewing area D2 respectively.In addition in the present embodiment, dispose on the active elements array substrates (not shown) of pixel cell 400 and also include many first capacitance electrodes 432 and many second capacitance electrodes 434, in Fig. 4, only illustrate one individually and illustrate for example.First capacitance electrode 432 for example is positioned at the first viewing area D1, and the second electric capacity potential electrode 434 is positioned at the second viewing area D2.
When pixel cell 400 shows,, corresponding first pixel electrode 410 is influenced respectively by different pressure reduction with the liquid crystal molecule of second pixel electrode, 420 tops by the electric capacity effect of first capacitance electrode 432 and second capacitance electrode 434.Therefore, can define the first viewing area D1 and the second viewing area D2 that presents different display brightness respectively.In fact, adjust first capacitance electrode 432 and second capacitance electrode 434 size in the first viewing area D1 and the second viewing area D2, or give first capacitance electrode 432 voltage different with second capacitance electrode 434, all can make the first viewing area D1 and the second viewing area D2 present different display brightness.In the present embodiment, the configuration of first capacitance electrode 432 and second capacitance electrode 434 for example makes the viewing area D1 that wins that higher display brightness is arranged, and the second viewing area D2 presents lower display brightness.
In general, among the first viewing area D1 and the second viewing area D2 of different display brightness, display brightness higher in the influence of low grey-tone image bigger, and in low grey-tone image the phenomenon of comparatively significant colour cast or color saturation deficiency often takes place.So, in the time of making pixel cell 400 on specific direction, present wider angular field of view and quality good display, can the first brighter viewing area D1 be compensated, just the low grey-tone image of centering compensates.
First alignment pattern that is arranged in the first viewing area D1 for example is a plurality of first orientation slits 416, and second alignment pattern that is arranged in the second viewing area D2 then for example is a plurality of second orientation slits 426.The angle of the first orientation slit, 416 bearing of trends and sweep trace 402 bearing of trends is first acute angle theta 1, and the angle of the second orientation slit, 426 bearing of trends and sweep trace 402 bearing of trends is second acute angle theta 2, wherein first acute angle theta 1 for example is 40 °, and second acute angle theta 2 is about 45 °.
Specifically, first pixel electrode 410 comprises the first crossed electrode pattern 412 and a plurality of first striped electrode pattern 414.The first crossed electrode pattern 412 for example is cross electrode pattern, the first viewing area D1 can be marked off four area I, II, III and IV.Among each area I, II, III and the IV, an end of these first striped electrode patterns 414 is connected with the first crossed electrode pattern 412, and the other end of the first striped electrode pattern 414 is away from the first crossed electrode pattern 412.In addition, just define the first orientation slit 416 between these first striped electrode patterns 414 that are arranged in parallel.
420 of second pixel electrodes comprise the second crossed electrode pattern 422 and a plurality of second striped electrode pattern 424.The second crossed electrode pattern 422 for example is cross electrode pattern, the second viewing area D2 can be marked off four area I, II, III and IV.Among each area I, II, III and the IV, an end of the second striped electrode pattern 424 for example is connected with the second crossed electrode pattern 422, and the other end of the second striped electrode pattern 424 is away from the second crossed electrode pattern 422.In addition, the second orientation slit 426 is between these second striped electrode patterns 424.In the present embodiment, the bearing of trend of the first orientation slit 416 and the second orientation slit 426 compares, and the bearing of trend of the first orientation slit 416 is than convergence sweep trace 402 bearing of trends.
In the common demonstration product, have relatively high expectations for the angular field of view on sweep trace 402 bearing of trends mostly, so can strengthen at the display effect that this side up when making pixel cell 400.With present embodiment, when pixel cell 400 display frames, liquid crystal molecule can be toppled over along the bearing of trend of the first orientation slit 416 and the second orientation slit 426.Therefore, in the first viewing area D1 or the second viewing area D2, be positioned at each area I, II, III can topple over towards four different directions respectively with the liquid crystal molecule of IV, thereby reach wide-visual angle effect.In addition, the bearing of trend of the first orientation slit 416 is comparatively near the bearing of trend of sweep trace 402, so during pixel cell 400 display frames, can present broad angular field of view on the bearing of trend of sweep trace 402.Simultaneously, the configuration of first capacitance electrode 432 and second capacitance electrode 434 makes the viewing area D1 that wins present bigger display brightness.Therefore, the first orientation slit 416 that is positioned at the first viewing area D1 helps the low grey-tone image of centering to compensate in the phenomenon of incidental colour cast in different visual angles place or color saturation deficiency.
In general, be 96 o'clock in the GTG value, pixel cell 400 can be used as the not index of foot phenomenon of colour cast or color saturation at the ratio P of the brightness value of locating with great visual angle and the brightness value of positive apparent time.The P value is more near 1, and it is faint more that promptly the remarked pixel unit presents the phenomenon of image colour cast.According to Simulation result, the P value of pixel cell 400 is about 2.32, and the P value of the pixel cell of traditional structure is about 2.7.By contrast, the color offset phenomenon of the pixel cell 400 of present embodiment is more not obvious, thereby has wide viewing angle display quality preferably, and the high-high brightness of image that pixel cell 400 presents is that the pixel cell of traditional structure presents 99% of image high-high brightness in addition.Generally speaking, pixel cell 400 not only can present good wide viewing angle display effect, and its maximum display brightness also still maintains good state.
Certainly, in other embodiments, when making display panels, the first orientation slit 416 and the second orientation slit 426 of different bearing of trends also can be formed on the counter electrode (not shown) of display panels.In addition, the first orientation slit 416 of different bearing of trends and the second orientation slit 426 also can be formed at counter electrode (not shown) and first pixel electrode 410 and second pixel electrode 420 on both simultaneously.
Below reintroduce a kind of design of display panels.Fig. 5 A is the partial top view of the display panels of another embodiment of the present invention, and Fig. 5 B is along the shown diagrammatic cross-section of hatching line AA ' among Fig. 5 A, and wherein Fig. 5 A only illustrates the scope of a pixel cell.Please be simultaneously with reference to Fig. 5 A and Fig. 5 B, display panels 500 comprises active elements array substrates 510, subtend substrate 530 and liquid crystal layer 550.Liquid crystal layer 550 is disposed between active elements array substrates 510 and the subtend substrate 530.Dispose sweep trace 512, data line 514a and 514b and pixel cell 520 on the active elements array substrates 510, pixel cell 520 electrically connects with sweep trace 512, data line 514a and 514b.Pixel cell 520 comprises the first active component 522a, the second active component 522b, the first pixel electrode 524a and the second pixel electrode 524b.The first active component 522a and the first pixel electrode 524a electrically connect, and the second active component 522b and second pixel electrode 524b electric connection.In addition, the first active component 522a and the second active component 522b electrically connect with different data line 514a and data line 514b respectively.Two data line 514a that pixel cell 520 is connected can import different data-signals with 514b and give the first pixel electrode 522a and the second pixel electrode 522b, with the first viewing area D1 and the second viewing area D2 that defines different display brightness.
Dispose first alignment pattern, 570, the first alignment pattern 570 among the first viewing area D1 and comprise a plurality of first orientation protrusions 572 and a plurality of first orientation slit 574.The second viewing area D2 then disposes second alignment pattern, 590, the second alignment pattern 590 and comprises a plurality of second orientation protrusions 592 and a plurality of second orientation slit 594.In display panels 500, the first orientation protrusion 572 and the second orientation protrusion 592 for example are disposed on the subtend substrate 530, and the first orientation slit 574 and the second orientation slit 594 for example are the slit pattern that is positioned on the first pixel electrode 524a and the second pixel electrode 524b.In fact, the angle of the bearing of trend of first alignment pattern 570 and sweep trace 512 bearing of trends is first acute angle theta 1, and the angle of the bearing of trend of second alignment pattern 590 and sweep trace 512 bearing of trends is second acute angle theta 2, and wherein first acute angle theta 1 is less than second acute angle theta 2.
The arrangement meeting of the liquid crystal molecule of liquid crystal layer 550 is perpendicular to the bearing of trend of the first orientation protrusion 572 and the second orientation protrusion 592.Therefore, in the present embodiment, the orientation meeting of liquid crystal molecule that is positioned at the second viewing area D2 is relatively near the bearing of trend of sweep trace 5 12.When display panels 500 was made into the demonstration product, the angular field of view of image on sweep trace 512 bearing of trends that the second viewing area D2 is presented was bigger.Therefore, present embodiment for example can be imported the first pixel electrode 524a and the second pixel electrode 524b with different data-signals via different data line 514a and 514b, so that the second viewing area D2 presents brighter display frame relatively.Thus, not only display panels 500 have the display effect of wide viewing angle, and on sweep trace 512 bearing of trends, the situation that colour cast and color saturation deficiency take place between different visual angles also will be improved.Simultaneously, the display brightness of display panels 500 can thereby significantly not reduce yet.
When the display brightness of the second viewing area D2 is big,, just help the show image of the low GTG of centering to compensate if make the bearing of trend of second alignment pattern 590 approach the bearing of trend of sweep trace 512.So display panels 500 does not present the display effect of wide viewing angle only, and the design of display panels 500 can make the display effect on sweep trace 512 bearing of trends better, thereby satisfies user's requirement.In addition, if will make the display effect of design on other specific directions of display panels 500 preferable, then can change the bearing of trend of first alignment pattern 570 and second alignment pattern 590, make the bearing of trend of the alignment pattern be positioned at the brighter viewing area of display brightness comparatively near this specific direction.
In other embodiments, first alignment pattern 570 and second alignment pattern 590 are not limited to be formed on the orientation slit on the different substrate and the matched combined of orientation protrusion.First alignment pattern 570 in the display panels 500 and second alignment pattern 590 also can only be made up of a plurality of orientation protrusions and wherein a kind of form of a plurality of orientation slit (not shown).In addition, first alignment pattern 570 and second alignment pattern 590 also can only be disposed on the active elements array substrates 510 or only be disposed on the subtend substrate 530.
Fig. 6 is the partial top view of the display panels of an embodiment more of the present invention.Please refer to Fig. 6, display panels 600 is roughly the same with display panels 500, so continue to use the element numbers in the part display panels 500.Also comprise first capacitance electrode 610 and second capacitance electrode 620 in the display panels 600.In addition, the first active component 522a and the second active component 522b are connected on same the data line 514a.In the present embodiment, make the viewing area D1 that wins as described below with the mode that the second viewing area D2 has different display brightness.
When display panels 600 showed, first capacitance electrode 610 and second capacitance electrode 620 for example had different current potentials.Therefore, first capacitance electrode 610 and second capacitance electrode 620 can produce different capacitive coupling effects with the first pixel electrode 524a and the second pixel electrode 524b.So, by the first pixel electrode 524a that is connected to same data line 514a and the second pixel electrode 524b, just produce different display voltage.In addition, the electric potential signal of first capacitance electrode 610 and second capacitance electrode 620 can change along with the design of different driving signal and pixel.The driving method of the display panels 600 of relevant present embodiment can be described with reference to the content of No. the 95132144th, TaiWan, China number of patent application, and its content is incorporated in this instructions for reference.
In the middle of the design of display panels 600, first alignment pattern 570 can change with different user demands with the bearing of trend of second alignment pattern 590.In fact, the bearing of trend that is arranged in the brighter viewing area alignment pattern of display brightness (570 or 590) can be adjusted near the visual angle and require on the bigger direction.So the design of display panels 600 also can be satisfied the visual angle requirement different demand of different users to different directions.
