The difference for facing thang-kng amount of sub-pixel in molecular domains, same subregion is smaller, right using the pixel electrode 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 same subregion uses the pixel electrode of formed objects, it is ensured that the brightness of sub-pixel is equal in same subregion
One property is preferable.Also, different subregions use pixel electrode of different sizes, can compensate between pixel column and pixel column just
Depending on thang-kng amount, 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

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, and a sub-pixel, the pixel electricity of each sub-pixel are included per sub-regions
The size of pole 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 pixel electrode of the sub-pixel bigger with the distance of central shaft, 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 can compensate for facing logical
