Further, with continued reference to Fig. 3, where curved face display panel on curved surface along the direction perpendicular to central shaft R,
And pointed to by central shaft R on direction B and direction B' away from central shaft R, the area of each block unit of same subregion is identical.
For example, the second sub-pixel SP2 and the second sub-pixel SP2' in the second subregion SAA2, the area of block unit are identical；
For example, the first sub-pixel SP1 and the first sub-pixel SP1' in the first subregion SAA1, the area of block unit are identical.
Pointed to where curved face display panel on curved surface along the direction perpendicular to central shaft R, and by central shaft R away from
On heart axle R direction B, the area of the pixel electrode of different subregions is sequentially reduced, for example, the first sub-pixel SP1', the 3rd son
The area of pixel SP3 and the second sub-pixel SP2 block unit is sequentially reduced；Where curved face display panel on curved surface along hang down
Directly in central shaft R direction, and pointed to by central shaft R on the direction B' away from central shaft R, the block unit of different subregions
Area is sequentially reduced, for example, the area of the first sub-pixel SP1, the 4th sub-pixel SP4 and the 5th sub-pixel SP5 block unit
It is sequentially reduced.
In this embodiment, the direction away from central shaft is being pointed to along the direction perpendicular to central shaft, and by central shaft
On, the distance difference of each sub-pixel and central shaft is smaller in same subregion, the difference for facing thang-kng amount of each sub-pixel
Smaller, same subregion uses the block unit of formed objects, reduces the difference of block unit size on same curved face display panel
It is different, reduce technological requirement；The distance difference of each sub-pixel and central shaft in different subregions is larger, each in different subregions
Individual sub-pixel faces differing greatly for thang-kng amount, and is pointed on the direction away from central shaft by central shaft, faces thang-kng amount and gets over
Come smaller, thus, the area for the block unit that different subregions are used also is sequentially reduced, on the basis of reduction technological requirement compared with
Compensate well and face thang-kng amount difference.
Further, obtained arc is intersected with perpendicular to the arbitrary plane of central shaft for curved surface where curved face display panel
Line all same, namely curved face display panel are launched into the rectangle that is shaped as after plane, and many height pictures of curved face display panel
The formation pixel column that element is upwardly extended in the side parallel to central shaft, the formation pixel upwardly extended in the side perpendicular to central shaft
OK, one or more pixel columns can be set to a sub-regions.Or, with reference to Fig. 3, include two in every sub-regions SAA
Individual pixel column.
In this embodiment, each pixel column sub-pixel and central shaft apart from all same, in units of pixel column draw
The difference for facing thang-kng amount of sub-pixel in molecular domains, same subregion is smaller, right using the block unit of formed objects
The influence that thang-kng dose-effect fruit is faced in compensation is small.
The sub-pixel that particularly a pixel column is set in the situation of a sub-regions, same subregion faces logical
Light quantity is identical, now, and the sub-pixel in same subregion uses the block unit of formed objects, it is ensured that sub- picture in same subregion
The brightness homogeneity of element is preferable.Also, different subregions use block unit of different sizes, can compensate for pixel column and pixel
Thang-kng amount is faced between row, curved face display panel brightness homogeneity is lifted.
Further, curved surface where curved face display panel is deposited with intersecting obtained camber line perpendicular to the arbitrary plane of central shaft
In situation about differing, for example, the curved surface where curved face display panel is the situation of a part for the side of trapezoidal round platform, such as
Curved surface where curved face display panel is sphere or the situation of a part for ellipsoid, for maximized compensation curved-surface display face
Each sub-pixel faces throughput difference on plate, include a sub-pixel per sub-regions, and each sub-pixel blocks list
The size of member determines that the bigger sub-pixel with the distance of central shaft faces thang-kng amount according to the distance of the sub-pixel and central shaft
It is smaller, so that the block unit of the sub-pixel bigger with the distance of central shaft, the area of block unit is smaller.
Further, Fig. 9 is the schematic diagram of curved face display panel provided in an embodiment of the present invention, and Figure 10 is to shown in Fig. 9
The curved face display panel cross-sectional view that tangentially C-C' is obtained, suitably with reference to Fig. 9, curved face display panel includes relative
Set the first arc in E1 and the second arc E2, in addition to be oppositely arranged, respectively with the first arc in E1 and the second arc E2 phases
Connection the first straight flange E3 and the second straight flange E4, on curved face display panel, had central shaft R the first subregion SAA1 and
The second subregion SAA2 away from central shaft R.

It is the corresponding height of subregion to define the vertical range between the center of subregion and the first plane S1, wherein, the
The corresponding height of one subregion SAA1 is d1, the corresponding height d of the second subregion2。
The area S of block unit in the first subregion1With the area S of the block unit in the second subregion2
Meet following relation：S1*d2=S2*d1。
For curved face display panel, the corresponding height of subregion is lower, and the distance of subregion and central shaft is bigger, subregion
Closer to the end of curved face display panel, sub-pixel faces that thang-kng amount is smaller in subregion, and in this embodiment, setting is blocked
The area of unit height corresponding with subregion where block unit is inversely proportional, that is, the corresponding height of subregion is lower, blocks
The area of unit is smaller, just can compensate for facing the difference of thang-kng amount.
