Such as, the aperture area of sub-pixel refers to lighting area or the glazed area of this sub-pixel.Correspondingly, the aperture area of pixel cell refers to the aperture area sum of each sub-pixel forming this pixel cell.Following embodiment can be identical therewith.
Such as, often row sub-pixel 101 comprises the sub-pixel of three kinds of colors, is respectively red sub-pixel 1011, green sub-pixels 1012 and blue subpixels 1013.Red sub-pixel 1011 is for showing redness, and green sub-pixels 1012 is for showing green, and blue subpixels 1013 is for showing blueness.Such as, a red sub-pixel 1011, green sub-pixels 1012 and a blue subpixels 1013 can form a pixel cell 123.Such as, but embodiment of the present utility model is not limited to the configuration of above-mentioned three primary colors, also can comprise the sub-pixel of other colors, white sub-pixels.
It should be noted that, in Fig. 2 a, 2b for the first sub-pixel P1 and the second sub-pixel P2 for green sub-pixels is described.First sub-pixel P1 and the second sub-pixel P2 also can be the sub-pixel for showing other colors.
Fig. 2 a, 2b show multiple sub-pixel unit 101 that display base plate is arranged in array, and there is shown 24 pixel cells, and suspension points wherein represents other unshowned pixel cells.
It should be noted that, in the present embodiment, the mid point on line direction is that the line segment that often row sub-pixel is formed is positioned at the abstract point of of centre position in the row direction, to facilitate description, instead of the concrete structure of outwardness in this display base plate.Similarly, the first sub-pixel and the second sub-pixel also define relative to the size of the mid point distance on line direction with it, but not refer in particular to certain sub-pixel of a certain position.Further, the first sub-pixel P1 and the second sub-pixel P2 is not limited to be positioned at the same side of the mid point 105 of the line segment that often row sub-pixel is formed, and the first sub-pixel P1 and the second sub-pixel P2 can be positioned at the both sides of the mid point 105 of the line segment that often row sub-pixel is formed.Following embodiment can be identical therewith.Such as, in green sub-pixels 1121-1128, comparatively speaking, for green sub-pixels 1121 and green sub-pixels 1122, green sub-pixels 1121 is the first sub-pixel P1, and green sub-pixels 1122 is the second sub-pixel P2; For green sub-pixels 1122 and green sub-pixels 1123, green sub-pixels 1122 is the first sub-pixel P1, and green sub-pixels 1123 is the second sub-pixel P2; For green sub-pixels 1123 and green sub-pixels 1124, then green sub-pixels 1123 is the first sub-pixel P1, and green sub-pixels 1124 is the second sub-pixel P2; For green sub-pixels 1122 and green sub-pixels 1127, then green sub-pixels 1122 is the first sub-pixel P1, and green sub-pixels 1127 is the second sub-pixel P2.
Such as, as shown in Fig. 2 a, 2b, what have an equidistance with the mid point 105 on line direction has equal aperture area for the sub-pixel 101 showing same color.
A pixel cell comprises multiple sub-pixel for showing different colours.Such as, it is multiple for showing in the sub-pixel of different colours that pixel cell comprises, can be identical for the Changing Pattern showing the sub-pixel unit of different colours.Such as, as shown in Fig. 2 a, 2b, sub-pixel P1 and P2 with said structure adheres to different pixel cells separately, the first pixel cell 1231 (right edge in such as figure) then comprising sub-pixel P1 to the distance of the mid point 105 on line direction be less than comprise sub-pixel P2 the second pixel cell 1232 (right edge in such as figure) to the distance of the mid point 105 on line direction, sub-pixel P1 and P2 is not limited to the green sub-pixels indicated in figure, also can refer to other sub-pixels for showing same color.The aperture area of the first pixel cell 1231 is greater than the aperture area of the second pixel cell 1232.
Such as, as shown in Fig. 2 a, 2b, often row sub-pixel can have identical height.Adjusted for the change that shows the aperture area of the sub-pixel of the same color change by sub pixel width.
The above-mentioned display base plate that the present embodiment provides can promote the transmitance of display panel central area, reaches the target promoting central area brightness, reduce power consumption, can make each several part pixel (sub-pixel) aperture opening ratio reasonable layout in display base plate.
In another example of the present embodiment, as shown in Fig. 2 a, 2b, often in row sub-pixel, from mid point 105 position near the line direction to away from mid point 105 position on line direction, the aperture area for each sub-pixel 101 showing same color reduces gradually.For green sub-pixels 1121-1124, the aperture area of green sub-pixels 1121,1122,1123,1124 reduces gradually.Because the aperture area for the sub-pixel showing same color be closely adjacent to each other reduces gradually, then each adjacent brightness for the sub-pixel showing same color also reduces gradually.Thus make central area luminance raising while making to take into account picture homogeneity, and every a line diverse location place luminance difference gradually changes, to obtain good visual effect.
Such as, from mid point 105 position near the line direction to away from mid point 105 position on line direction, aperture area for showing red red sub-pixel 1011 reduces gradually, aperture area for showing green green sub-pixels 1012 reduces gradually, reduces gradually for the aperture area showing blue blue subpixels 1013.Then from mid point 105 position near the line direction to away from mid point 105 position on line direction, the aperture area of each pixel cell 123 reduces gradually.Because the aperture area of each pixel cell reduces gradually, then the brightness of each pixel cell also reduces gradually.Thus make central area luminance raising while making to take into account picture homogeneity, and every a line diverse location place luminance difference gradually changes, to obtain good visual effect.
In another example of the present embodiment, often in row sub-pixel 101, from mid point 105 position near line direction to away from mid point 105 position on line direction, be that arithmetic progression reduces for showing the aperture area of each sub-pixel 101 of same color.Equally, because the brightness of each adjacent sub-pixel for showing same color is that arithmetic progression reduces.Thus make central area luminance raising, and every a line diverse location place luminance difference is that arithmetic progression gradually changes, to obtain good visual effect.
Such as, often in row sub-pixel 101, from mid point 105 position near the line direction to away from mid point 105 position on line direction, the aperture area of each pixel cell be arithmetic progression reduction.Equally, the brightness because of each pixel cell is that arithmetic progression reduces, thus makes central area luminance raising, and every a line diverse location place luminance difference is that arithmetic progression gradually changes, to obtain good visual effect.
Such as, be even number in every row number of pixel cells, each sub-pixel is contour, from mid point 105 position near the line direction to away from each pixel cell in mid point 105 position on line direction and when all reducing in arithmetic progression for the aperture area of the sub-pixel showing same color, the every a line of display base plate is set there is N number of pixel cell, center N/2 (1/2nd N) aperture area that is individual and N/2+1 (1/2nd N add one) individual pixel cell is X (maximum pixel aperture area), arranging pixel cell aperture area minimum on its edge is kX, between adjacent pixel unit, aperture area is arithmetic progression, then tolerance is (1-k) X/ (N/2-1), then total aperture area of its pixel cell is Sn=2 × 1/2 × (kX+X) × N/2=1/2 × (1+K) × X × N.Suppose usually designing in (namely the aperture area of each pixel is identical), each pixel openings area is A, then compared to the usual pixel of the same total area, for center pixel, transmitance is X=2A/ (1+k), transmitance promotes than being X/A=2/ (1+k), can show that K value (in namely often going, minimum pixel opening is divided by the ratio of maximum pixel opening) promotes the relation table of ratio with transmitance thus:
Table one: K value and transmitance promote the relation table of ratio
| K value | Transmitance promotes ratio (%) |
| 0.95 | 2.6 |
| 0.9 | 5.3 |
| 0.85 | 8.1 |
| 0.8 | 11.1 |
Can find out that K is less by table one, it is higher that its center transmitance promotes ratio.Consider the picture uniformity requirements of normal display panel, when K value is set to 0.8, center pixel unit (sub-pixel) transmitance can promote 11.1%.
Such as, in the display base plate that the utility model one embodiment provides, often in row sub-pixel, the ratio (K value) of the aperture area of the sub-pixel unit that the minimum sub-pixel unit of aperture area is maximum with the aperture area for showing same color is more than or equal to 0.8 and is less than 1.Equally, when showing the sub-pixel Changing Pattern of different colours and being consistent, often in row sub-pixel, the ratio (K value) of the aperture area of the pixel cell that aperture area is minimum and the maximum pixel cell of aperture area is more than or equal to 0.8 and is less than 1.
Such as, in an example of the present embodiment, as shown in Fig. 2 a, 2b, often in row sub-pixel, the first sub-pixel P1 and the second sub-pixel P2 is the sub-pixel for showing same color be closely adjacent to each other.
