First both alignment layers 13 can be formed at one of them of first substrate 11 and second substrate 12, the second both alignment layers 14 can be formed at first substrate 11 and second substrate 12 wherein another.In other words, if when the first both alignment layers 13 is formed at first substrate 11, the second both alignment layers 14 is formed at second substrate 12; Otherwise if the first both alignment layers 13 is formed at second substrate 12, the second both alignment layers 14 is formed at first substrate 11.In the present embodiment, be formed at first substrate 11(thin film transistor base plate with the first both alignment layers 13) on, and the second both alignment layers 14 is formed at second substrate 12(colored optical filtering substrates) be above example.Wherein, the material of the first both alignment layers 13 and the second both alignment layers 14 is for example and without limitation to pi (polyimide, PI).

By light allocating process, and utilize the first both alignment layers 13 and the second both alignment layers 14, different lqiuid crystal molecule tipping directions can be defined in each pixel cell of display panels 1, in this, for four different lqiuid crystal molecule tipping directions.Specifically, under specific conditions of exposure, can by the both alignment layers orientation of thin film transistor base plate (hereinafter referred to as TFT) side in the first direction of such as column direction Y or second direction, and by the both alignment layers orientation of colored optical filtering substrates (hereinafter referred to as CF) side in the first direction of such as line direction X or second direction, and form multi-field liquid crystal molecules tilt direction by the collocation of the both alignment layers of this TFT side and CF side and combination.Below, its content is described in detail with reference to relevant indicators.

Please refer to shown in Fig. 3 A to Fig. 3 D, it is respectively the schematic diagram that light allocating process is applied to the adjacent pixel unit P1 ~ P4 of display panels 1.Wherein, Fig. 3 A and Fig. 3 B is shown as the alignment direction schematic diagram of the both alignment layers of TFT side and the both alignment layers of CF side respectively, Fig. 3 C is the toppling direction schematic diagram of the liquid crystal molecule in each field in pixel cell P1 ~ P4, and Fig. 3 D is the dark line schematic diagram that pixel cell P1 ~ P4 produces.In this, pixel cell P1 ~ P4 can be considered a group, and by the group of multiple P1 ~ P4 is formed rectangular pixel cell.In addition, pixel cell P1 and pixel cell P2 is adjacent on column direction Y, pixel cell P3 and pixel cell P4 is also adjacent on column direction Y, and pixel cell P1 and pixel cell P3 is adjacent on line direction X, and pixel cell P2 and pixel cell P4 is also adjacent on line direction X.

Each pixel cell (such as P1, P2, P3 or P4) represents one pixel (subpixel) of display panels 1.In the present embodiment, as shown in Figure 3 C, pixel cell P1 ~ P4 is divided into 8 fields respectively, and 8 fields can be arranged in four lines two row, therefore pixel cell P1 ~ P4 sequentially has the first row from top to bottom respectively to fourth line; By sequentially having first row and secondary series respectively from left to right.But, in other enforcement aspect, pixel cell P1 ~ P4 also can be divided into 4 fields respectively, and 4 fields can be arranged in two row two and arrange or other; Or pixel cell P1 ~ P4 also can be divided into 16 fields respectively, and 16 fields can be arranged in eight row two and arrange or other, and the present invention does not limit the number in the field that each pixel cell is distinguished.

Shown in Fig. 3 C, the first row of each pixel cell and these fields of the second row belong to one first district A1, and these fields of the third line and fourth line belong to one second district A2.Wherein, the first district A1 and the second district A2 is electrically connected to same sweep trace respectively, and provides image data by different data lines.By each pixel cell is divided into twoth district, and can obtain close to gamma curve when facing in gamma curve (Gamma Curved) different in axle side-looking in conjunction with twoth district, display panels 1 can be made to have preferably display quality.

In addition, the direction of arrow of Fig. 3 A or Fig. 3 B is the alignment direction of the both alignment layers of TFT side or CF side, and the direction of arrow in the every field of Fig. 3 C is the toppling direction of liquid crystal molecule (major axis), it is the TFT side both alignment layers in this field and the resultant direction of CF side both alignment layers.The alignment direction of the such as both alignment layers of TFT side is that the first direction Y1(of column direction Y is downward), the alignment direction of the both alignment layers of CF side be the second direction X2(of line direction X left), then liquid crystal molecule will swing to the direction of lower-left, as shown in the direction of arrow in the field of the first row first row of pixel cell P1, by that analogy.

Shown in Fig. 3 A and Fig. 3 C, the alignment direction in these fields that TFT side both alignment layers corresponds to the first row of the first pixel cell P1 and the second pixel cell P2 is the first direction Y1 of column direction Y, and the alignment direction corresponding to these fields of the secondary series of the first pixel cell P1 and the second pixel cell P2 is the second direction Y2 of column direction Y.In addition, the alignment direction in these fields that TFT side both alignment layers corresponds to the first row of the 3rd pixel cell P3 and the 4th pixel cell P4 is the second direction Y2 of column direction Y, and the alignment direction corresponding to these fields of the secondary series of the 3rd pixel cell P3 and the 4th pixel cell P4 is the first direction Y1 of column direction Y.

In addition, as shown in Fig. 3 B and Fig. 3 C, the alignment direction that CF side both alignment layers corresponds to the first pixel cell P1 and second row of the 3rd pixel cell P3 and these fields of the third line is all the first direction X1 of line direction X, and the alignment direction corresponding to the first pixel cell P1 and the first row of the 3rd pixel cell P3 and these fields of fourth line is all the second direction X2 of line direction X.Similarly, the alignment direction that CF side both alignment layers corresponds to the second pixel cell P2 and second row of the 4th pixel cell P4 and these fields of the third line is all the first direction X1 of line direction X, and the alignment direction corresponding to the second pixel cell P2 and the first row of the 4th pixel cell P4 and these fields of fourth line is all the second direction X2 of line direction X.In this, CF side both alignment layers corresponds to the alignment direction in the first pixel cell P1 and second row of the 3rd pixel cell P3 and these fields of the third line, is all the first direction X1 of line direction X with the alignment direction corresponding to the second pixel cell P2 and second row of the 4th pixel cell P4 and these fields of the third line.

In addition, as shown in Fig. 3 C and Fig. 3 D, the first district A1 of each pixel cell or these fields of the second district A2 are defined four different lqiuid crystal molecule tipping directions by TFT side both alignment layers and CF side both alignment layers respectively.Different liquid crystal toppling directions is observed under linear Polarizer (linear polarizer), can occur the dark line of two types: " Swastika " font and 8 fonts (8 of inclination) in display.For example, for pixel cell P1, the liquid crystal toppling direction in four fields of the first district A1 is combined into counterclockwise, then the corresponding dark line obtained is as the Swastika of Daoing “ of Fig. 3 D " font, and oblique 8 fonts in the right side of dark line as Fig. 3 D obtained corresponding to the liquid crystal toppling direction in four fields of the second district A2.Again for pixel cell P3, oblique 8 fonts in the left side of dark line as Fig. 3 D obtained corresponding to the liquid crystal toppling direction in four fields of the first district A1, and the liquid crystal toppling direction in four fields of the second district A2 is combined into clockwise direction, the dark line that correspondence obtains is as Fig. 3 D “ Swastika " font, all the other are by that analogy.Therefore, by the TFT side both alignment layers of Fig. 3 A and Fig. 3 B and the alignment direction of CF side both alignment layers, obtain the toppling direction of the liquid crystal molecule in each field of the pixel cell as Fig. 3 C, and then obtain the dark line structure of Fig. 3 D.In this, Fig. 3 D is called Shuan “ Swastika 8 " design.

Wherein, take up an official post in two adjacent pixel cells in line direction X, adjacent these fields that both have a common boundary are defined identical lqiuid crystal molecule tipping direction by the both alignment layers of the both alignment layers of TFT side and CF side.In other words, as shown in Figure 3 C, for pixel cell P1 and pixel cell P3, the lqiuid crystal molecule tipping direction of the secondary series of pixel cell P1 is identical with the lqiuid crystal molecule tipping direction of the first row of adjacent pixel cell P3.In the same manner, the lqiuid crystal molecule tipping direction of the secondary series of pixel cell P2 is identical with the lqiuid crystal molecule tipping direction of the first row of adjacent pixel cell P4.

Therefore, please refer to shown in Fig. 3 E and Fig. 3 F, wherein, when Fig. 3 E is the accurate contraposition of TFT substrate and CF substrate, the schematic diagram in these fields of adjacent two pixel cells (such as P1, P3) on line direction X, and Fig. 3 F is TFT substrate and CF substrate produces when misplacing, the schematic diagram in these fields of adjacent two pixel cells (such as P1, P3) on line direction.Wherein, TFT substrate and CF substrate produce the reason that misplaces and can cause because of technique aligning accuracy deficiency, also may be because display panels 1 itself is that a bending display panel produced, not limit.If bending display panel causes, the then first substrate 11(of display panels 1 and second substrate 12) in the row direction X there is a bending side, this side has a radius-of-curvature.The radius-of-curvature of side such as can between 500 millimeters to 10000 millimeters.Preferably, radius-of-curvature more can between 2000 millimeters to 6000 millimeters.Because the alignment direction of the second both alignment layers 14 is parallel with the line direction X being arranged in rectangular pixel cell, therefore, bending parallel with the alignment direction (line direction X) of the second both alignment layers 14 in the row direction on X of display panels 1.Second both alignment layers 14 of the display panels 1 of the present embodiment is formed at second substrate 12(colored optical filtering substrates) on, therefore the alignment direction that can be called for short CF side both alignment layers is identical with the bending direction of display panels 1.

As shown in FIGURE 3 E, when two substrates does not misplace, then in pixel cell P1, P3, the area of every field is balance.But, as illustrated in Figure 3 F, if TFT substrate and CF substrate produce when misplacing, pixel cell P1, P3 will make black-matrix layer BM also produce skew in the skew of horizontal direction (line direction X), and then make the area imbalance (field C diminishes, and field D becomes large) in these fields in pixel.But, the color presented due to these pixel cells in the row direction X such as with RGB, RGB, RGB ... mode cycle arrangement, if therefore on display panel, the field C of all R of first row diminishes, field D becomes large, then the field C of all R of the 4th row by changes greatly, field D will diminish, the field C of all R of the 7th row diminishes again, field D becomes large again ...Similarly, the situation of G and B is also identical.Therefore, for whole display panels 1, in pixel, the self compensation effect because of all pixel cells makes overall field have the result of balance by the area imbalance in these fields, therefore the field area caused because misplacing can be improved uneven and affect the problem of display panel side optometry performance, and then display panels 1 is made to have preferably display quality.

In addition, shown in Fig. 3 C, in wantonly two pixel cells adjacent on column direction Y, adjacent these fields that both have a common boundary are defined identical lqiuid crystal molecule tipping direction by TFT side both alignment layers and CF side both alignment layers.Specifically, in the present embodiment, fourth line first row and the secondary series of pixel cell P1 and the first row first row of pixel cell P2 and secondary series have identical lqiuid crystal molecule tipping direction.

In addition, the field of the second row first row of each pixel cell and secondary series is identical with the alignment direction in the field of the third line first row and secondary series respectively.Specifically, in each pixel cell P1, P2, P3 or P4, the field of the second row first row and secondary series is identical with the alignment direction in the field of the third line first row and secondary series respectively.Because the alignment direction of CF side both alignment layers in the second row first row of each pixel cell and the field of secondary series is identical with the alignment direction in the field of the third line first row and secondary series respectively, therefore the first district A1 of each pixel cell is identical with the liquid crystal toppling direction of the intersection of the second district A2.Therefore, if when TFT substrate and CF substrate produce and misplace, the discontinuous boundary line of alignment direction can not be produced between the intersection being offset from the first district A1 and the second district A2 of the black-matrix layer of vertical direction (column direction Y), therefore, extra dark line can not be produced between first district A1 of each pixel cell and the second district A2, therefore, the penetrance of display panels 1 can not be reduced and affect its display quality.

In addition, please respectively with reference to shown in Fig. 4 A to Fig. 4 D, Fig. 5 A to Fig. 5 D and Fig. 6 A to Fig. 6 D, it is respectively the difference enforcement aspect schematic diagram that light allocating process is applied to the adjacent pixel unit P1 ~ P4 of display panels 1.

As shown in fig. 4 a and fig. 4b, main different of Fig. 4 A and Fig. 4 B and Fig. 3 A and Fig. 3 B are, in the CF side both alignment layers of Fig. 4 B, the alignment direction in each region respectively with Fig. 3 B contrary (alignment direction of the TFT side both alignment layers of Fig. 4 A and Fig. 3 A is identical).In addition, as shown in Fig. 5 A and Fig. 5 B, main different of Fig. 5 A and Fig. 5 B and Fig. 3 A and Fig. 3 B are, in the TFT side both alignment layers of Fig. 5 A, the alignment direction in each region respectively with Fig. 3 A contrary (alignment direction of the CF side both alignment layers of Fig. 5 B and Fig. 3 B is identical).In addition, as shown in Fig. 6 A and Fig. 6 B, main different of Fig. 6 A and Fig. 6 B and Fig. 5 A and Fig. 5 B are, in the CF side both alignment layers of Fig. 6 B, the alignment direction in each region respectively with Fig. 5 B contrary (alignment direction of the TFT side both alignment layers of Fig. 6 A and Fig. 3 A is identical).Therefore, the liquid crystal molecule in each field of pixel cell P1 ~ P4 toppling direction and corresponding dark line can according to above-mentioned explanation the corresponding pattern obtained as shown in Fig. 4 C and Fig. 4 D, Fig. 5 C and Fig. 5 D, Fig. 6 C and Fig. 6 D.

In addition, in Fig. 4 series, the serial and Fig. 6 of Fig. 5 are serial, the area imbalance in these fields of each pixel of panel also makes entirety have the result of balance because of the self compensation effect of all pixel cells, therefore the orientation that Fig. 4 is serial, Fig. 5 is serial and Fig. 6 is serial combination also can improve the unbalanced problem of field area that two substrates causes because of skew, dislocation respectively, and then make display panels 1 have preferably display quality, its detail can refer to Fig. 3 series and illustrates, repeats no more.

But, shown in Fig. 3 D, the dark line produced due to Fig. 3 D is two " Swastika 8 " patterns; when panel is the display of low GTG and pixel cells all in display panels 1 is such as turned off the second district A2 and light the first district A1 simultaneously; then along column direction Y; each pixel cell (such as pixel cell P1, P2) of the n-th row is by " Swastika " of appearance first district A1, and 8 of the first district A1 then appears in each pixel cell (such as pixel cell P3, P4) of the (n+1)th row.Because n-th lists existing dark line whole “ of Weiing Swastika ", (n+1)th to list existing dark line be all 8; take line direction as RGB, RGB, RGB ... red R be example; the whole “ Swastika of Weiing of the R of first row ", the R of the 4th row is all then 8, R whole “ Swastika of Weiing again of the 7th row " ...; therefore for beholder, the inequality because of red luma is produced the problem (green G and blue B also has same case) of the bright concealed wire of vertical direction (column direction Y).

In order to improve the problem of vertical bright concealed wire, please refer to shown in Fig. 7 A to Fig. 7 D, it is respectively the another enforcement aspect schematic diagram that light allocating process is applied to the adjacent pixel unit P1 ~ P4 of display panels 1.

Main different of Fig. 7 A and Fig. 7 B and Fig. 3 A and Fig. 3 B are, the alignment direction of the TFT side both alignment layers of Fig. 7 A is identical with Fig. 3 A, but in the CF side both alignment layers of Fig. 7 B, the alignment direction in each region is different from Fig. 3 B.Wherein, the CF side of Fig. 3 B is that X2, X1, X1, X2, X2, X1, X1, X2(X2, X1, X1, X2 repeat along each field alignment direction of column direction Y), but the CF side of Fig. 7 B is X2, X1, X1, X2, X1, X2, X2, X1 along each field alignment direction of column direction Y.Therefore, the pattern that the toppling direction of the liquid crystal molecule in each field of pixel cell P1 ~ P4 can be complied with above-mentioned explanation with corresponding dark line and be obtained as shown in Fig. 7 C and Fig. 7 D, its detail can refer to above-mentioned explanation, repeats no more.In this, Fig. 7 D is called staggered Shuan “ Swastika 8 " design.

Wherein, as seen in figure 7 c, in wantonly two pixel cells (P1 and P2 or P3 and P4) adjacent on column direction Y, adjacent these fields that both have a common boundary are defined different lqiuid crystal molecule tipping directions (fourth line of pixel cell P1 is different from the first row of pixel cell P2) by TFT side both alignment layers and CF side both alignment layers.In addition, CF side both alignment layers corresponds to the alignment direction (first direction X1) in the first pixel cell P1 and second row of the 3rd pixel cell P3 and these fields of the third line, with the reverse direction of the alignment direction (second direction X2) corresponding to the second pixel cell P2 and second row of the 4th pixel cell P4 and these fields of the third line line direction X each other.

Therefore, when panel is the display of low GTG and pixel cells all in display panels 1 is such as turned off all second district A2 and light the first all district A1 simultaneously, as seen in figure 7e, then n-th arrange the dark Wen “ Swastika that the first district A1 such as appears in the capable pixel cell of m ", n-th arranges the dark line 8 that the first district A1 appears in the capable pixel cell of m+1, n-th arranges the dark Wen “ Swastika that the first district A1 appears in the capable pixel cell of m+2 " ..., (n+1)th arranges the dark line 8 that the first district A1 appears in the capable pixel cell of m, (n+1)th arranges the dark Wen “ Swastika that the first district A1 appears in the capable pixel cell of m+1 " ....Therefore, because the pixel cell of each row is all shown as “ Swastika 8 Swastika 8 Swastika 8 ... " staggered, therefore for beholder, the problem of the bright concealed wire of vertical direction can not be produced because of the inequality of each row brightness.

Again one carry be, in the diagram of Fig. 7 A to Fig. 7 D, the same mode of copying above-mentioned Fig. 4 A to Fig. 4 D, Fig. 5 A to Fig. 5 D and Fig. 6 A to Fig. 6 D of deviser, the orientation of the orientation of the TFT side of Fig. 7 A and the CF side of Fig. 7 B entered combination change on column direction respectively and obtain other three kinds of different combinations, and then obtain the toppling direction of pixel cell each field liquid crystal molecule and the dark line of correspondence, in this, repeat no more.

In addition, please refer to shown in Fig. 8 A and Fig. 8 B, it is respectively schematic perspective view and the schematic top plan view of the display panels 2 of another enforcement aspect of present pre-ferred embodiments.

The display panels 2 of the present embodiment is a bending display panel, and comprises first substrate 21 and a second substrate 22.First substrate 21 and second substrate 22 are oppositely arranged.In this, first substrate 21 is for thin film transistor base plate, it is formed with the circuit driving each pixel cell, and second substrate 22 is for colored optical filtering substrates, and it is formed with chromatic filter layer.But, in other embodiments, first substrate 21 can be a colored optical filtering substrates, and second substrate 22 can be a thin film transistor base plate.

Bending display panels 2 has a bending display surface AA, and display surface AA can be a cambered surface.In other words, when display panels 2 is seen in side, the two side portions of display panels 2 can comparatively bend or tilt by center section.In this, for display panels 2 two side portions compared with curved under center section.Although display panels 2 is a bending display panel, in time overlooking display panels 2, is still shown as a square (rectangle), as shown in Figure 8 B.In addition, display panels 2 more can comprise a liquid crystal layer (figure does not show).Liquid crystal layer is arranged between first substrate 21 and second substrate 22, and has multiple liquid crystal molecule (figure does not show).Wherein, first substrate 21 can form multiple pixel cell with second substrate 22 and liquid crystal layer, and these pixel cells be configured to by row with row form rectangular, each pixel cell is divided into multiple field, and these fields of each pixel cell be equally configured to by row with row form rectangular.

First substrate 21 in the row direction X has a bending first side S1, and second substrate 22 also has a corresponding bending second side S2.In the vertical first side S1(or second side S2 of first substrate 21) side-looking direction on, bending first side S1 or second side S2 has a radius-of-curvature.The present embodiment restriction radius-of-curvature (500≤Qu leads Ban Jing≤10000) between 500 millimeters to 10000 millimeters.Preferably, radius-of-curvature more can between 2000 millimeters to 6000 millimeters (2000≤Qu leads Ban Jing≤6000).

In addition, display panels 2 more comprises one first both alignment layers and one second both alignment layers (figure does not show).First both alignment layers is formed at one of them of first substrate 21 or second substrate 22, and its alignment direction is parallel with column direction Y.Second both alignment layers be formed at first substrate 21 or second substrate 22 wherein another, and its alignment direction is parallel with the line direction X being arranged in rectangular pixel cell.In other words, if when the first both alignment layers is formed at first substrate 21, the second both alignment layers is then formed at second substrate; Otherwise if the first both alignment layers is formed at second substrate 22, the second both alignment layers is then formed at first substrate 21.The present embodiment is formed at first substrate 21(TFT with the first both alignment layers) time, and the second both alignment layers is formed at second substrate 22(CF) be example.

Because the alignment direction of the second both alignment layers is parallel with the line direction X being arranged in rectangular pixel cell, therefore, display panels 2 is bending parallel with the alignment direction (line direction X) of the second both alignment layers on X in the row direction.Second both alignment layers of the display panels 2 of the present embodiment is formed at second substrate 22(colored optical filtering substrates) on, therefore the alignment direction that can be called for short CF side both alignment layers is identical with the bending direction of display panels 2.

Display panels 2 is bending display panel, therefore colored optical filtering substrates and thin film transistor base plate may produce dislocation, make these field areas in each pixel uneven and affect display quality, therefore it is identical with above-mentioned display panels 1, the same as light allocating process, under specific conditions of exposure, by the both alignment layers orientation of thin film transistor base plate (TFT) in the first direction of such as column direction Y or second direction, and by the both alignment layers orientation of colored optical filtering substrates side (CF) in the first direction of such as line direction X or second direction, and form multi-field liquid crystal molecules tilt direction by the collocation of this two-layer both alignment layers and combination, the same result making the overall field of display panel have balance by the self compensation effect of all pixel cells.Therefore the same can to improve field area that two substrates causes because misplacing uneven and affect the problem of display panels 2 side-looking optical appearance, and then make display panels 2 have preferably display quality.

In addition much more no longer, other technical characteristic of display panels 2 and light allocating process are applied to the detailed content of display panels 2, can refer to above-mentioned, to explain.

In sum, according in display panels of the present invention, multiple pixel cell be configured to by row and row form rectangular, and each pixel cell is divided into multiple field.In addition, the alignment direction of the first both alignment layers is parallel with column direction, and the alignment direction of the second both alignment layers is parallel with line direction.In addition, these fields of these pixel cells are defined different lqiuid crystal molecule tipping directions by the first both alignment layers from the second both alignment layers, and take up an official post in two adjacent pixel cells in line direction, adjacent these fields that both have a common boundary are defined identical lqiuid crystal molecule tipping direction by the first both alignment layers and the second both alignment layers.By this, for whole display panels, because of skew or the unbalanced problem of these field areas caused that misplaces in pixel, self compensation effect because of all pixel cells is achieved a solution, therefore pixel neighborhoods area can be improved uneven and affect the problem of the optical appearance of side-looking, and then display panels is made to have preferably display quality.

The foregoing is only illustrative, but not be restricted person.Anyly do not depart from spirit of the present invention and category, and to its equivalent modifications of carrying out or change, all should be contained in right.
