In one-domain LC Display, observers see the correct image information at direct viewing angle, but get the wrong or deviated image information from other viewing angles. This is because that the light transmittance of different incident angle of light to the LC cell is different 。

By Ultra View Switching(UVS) technology, the GSI phenomenon in lower viewing angle and wash-out phenomenon in upper viewing angle are both improved respectively. The gamma curve improvement in upper and lower view angle is also significantly.
