Process.
Wherein, the pixel electrode at the position of sub-pixel SP generally use tin indium oxide (Indium Tin Oxide,
ITO) transparent electrode materials such as film are made, and the light that backlight module generates needs to expose to liquid crystal layer after penetrating pixel electrode,
Thus, pixel electrode can make to generate light loss by the light of sub-pixel.
In embodiment provided by the invention, the first subregion SAA1 with respect to the second subregion SAA2 closer to central axis R,
Second subregion SAA2 with respect to the first subregion SAA1 closer to the end of curved face display panel, thus, as shown in Fig. 2, first
The light passing amount of facing of the first sub-pixel SP1 is faced greater than the second sub-pixel SP2 in the second subregion SAA2 in subregion SAA1
Light passing amount.
The pixel electrode of the first sub-pixel SP1 makes to generate by the light of the first sub-pixel SP1 in first subregion SAA1
First light loss amount, the pixel electrode of the second sub-pixel SP2 makes to produce by the light of the second sub-pixel SP2 in the second subregion SAA2
Raw second light loss amount, the area that setting is located at each pixel electrode in the first subregion SAA1, which is greater than, is located at the second subregion SAA2
The area of interior each pixel electrode SAA2, so that the first light loss amount is greater than the second light loss amount, just just to the first sub-pixel SP1
Light passing amount of facing depending on light passing amount greater than the second sub-pixel SP2 is compensated, although that is, the first sub-pixel SP1's faces
Light passing amount is big, and the light loss generated on the pixel electrode across the light of the first sub-pixel SP1 is also more, although the second sub-pixel
SP2's faces that light passing amount is small, but also less across the light loss that the light of the second sub-pixel SP2 generates on the pixel electrode, thus,
For the first subregion SAA1 and the second subregion SAA2, is compensated for by the difference in size of pixel electrode and face the generation of light passing amount
It is inhomogenous.
In conclusion using embodiment provided by the invention, at the position close to curved face display panel central axis, namely
At the position for facing the biggish sub-pixel of light passing amount, the area of the pixel electrode of sub-pixel is bigger, far from curved face display panel
At the position of central axis, namely to face at the position of the lesser sub-pixel of light passing amount, the area of the pixel electrode of sub-pixel is smaller,
The inhomogenous of light passing amount generation is faced by the size disparity compensation of pixel electrode, to improve curved face display panel
Brightness homogeneity is able to ascend the display effect of curved face display panel.
Further, with continued reference to Fig. 3, where curved face display panel on curved surface along the direction perpendicular to central axis R,
And be directed toward on the direction B and direction B' far from central axis R by central axis R, the area of each pixel electrode of same subregion is identical.
For example, being located at the second sub-pixel SP2 and the second sub-pixel SP2' in the second subregion SAA2, the face of the pixel electrode of sub-pixel
Product is identical；For example, being located at the first sub-pixel SP1 and the first sub-pixel SP1' in the first subregion SAA1, the pixel of sub-pixel
The area of electrode is identical.
It is being directed toward far from curved surface along the direction perpendicular to central axis R, and by central axis R where curved face display panel
On the direction B of mandrel R, the area of the pixel electrode of different subregions is sequentially reduced, for example, the first sub-pixel SP1', third are sub
The area of the pixel electrode of pixel SP3 and the second sub-pixel SP2 is sequentially reduced；Where curved face display panel on curved surface along hang down
Directly in the direction of central axis R, and it is directed toward on the direction B' far from central axis R by central axis R, the pixel electrode of different subregions
Area is sequentially reduced, for example, the first sub-pixel SP1, the 4th sub-pixel SP4 and the 5th sub-pixel SP5 pixel electrode area
It is sequentially reduced.
In this embodiment, the direction far from central axis is being directed toward along the direction perpendicular to central axis, and by central axis
On, the distance difference of each sub-pixel and central axis is smaller in same subregion, the difference for facing light passing amount of each sub-pixel
Smaller, same subregion uses the pixel electrode of same size, reduces the difference of pixel electrode size on same curved face display panel
It is different, reduce technique requirement；The distance difference of each sub-pixel and central axis in different subregions is larger, each in different subregions
A sub-pixel faces differing greatly for light passing amount, and is directed toward on the direction far from central axis by central axis, faces light passing amount and gets over
Come it is smaller, thus, the area for the pixel electrode that different subregions use also is sequentially reduced, on the basis of reducing technique and requiring compared with
It compensates well and faces light passing amount difference.
Further, the arc intersected for curved surface where curved face display panel with the arbitrary plane perpendicular to central axis
Line is all the same namely curved face display panel to be launched into the shape after plane be rectangle, and multiple sub- pictures of curved face display panel
The formation pixel column that element is upwardly extended in the side for being parallel to central axis, in the formation pixel that the side perpendicular to central axis upwardly extends
Row, can set a sub-regions for one or more pixel columns.Alternatively, including two in each subregion SAA with reference to Fig. 3
A pixel column.
In this embodiment, each pixel column sub-pixel is all the same at a distance from central axis, is drawn as unit of pixel column
The difference for facing light passing amount of molecular domains, the sub-pixel in same subregion is smaller, right using the pixel electrode of same size
The influence that light passing dose-effect fruit is faced in compensation is small.
The case where especially setting a sub-regions for a pixel column, facing for sub-pixel in same subregion are logical
Light quantity is identical, at this point, same subregion uses the pixel electrode of same size, guarantees that the brightness of sub-pixel in same subregion is equal
One property is preferable.Also, different subregions use pixel electrode of different sizes, can compensate between pixel column and pixel column just
Depending on light passing amount, curved face display panel brightness homogeneity is promoted.
Further, the camber line that curved surface where curved face display panel intersects with the arbitrary plane perpendicular to central axis is deposited
In different situation, for example, the curved surface where curved face display panel is the situation of a part of the side of trapezoidal rotary table, such as
Curved surface where curved face display panel is the situation of a part of spherical surface or ellipsoid, in order to maximumlly compensate curved-surface display face
Each sub-pixel faces throughput difference on plate, and each subregion includes a sub-pixel, the pixel electricity of each sub-pixel
The size of pole determines that the bigger sub-pixel at a distance from central axis faces light passing amount according to the sub-pixel at a distance from central axis
Smaller, thus the pixel electrode of sub-pixel bigger at a distance from central axis, the area of pixel electrode is smaller.
It should be noted that above-mentioned part does not limit the concrete shape of pixel electrode, structure, it is logical can compensate for facing
Under conditions of light quantity difference, the pixel electrode of the embodiment of the present invention can be using arbitrary shape in display panel in the prior art
Pixel electrode.For example, the pixel electrode of curved face display panel is one-domain structure, pixel electrode includes multiple extending in the same direction
Electrode strip, there is between two neighboring electrode slit.Alternatively, the pixel electrode of curved face display panel may be double farmland knots
Structure, pixel electrode are divided into two farmlands, and pixel electrode equally includes multiple electrodes item, and each electrode strip is in same farmland along same
One direction extends, and extends in different directions in different farmlands, equally has slit between two neighboring electrode strip.
