Techniques to Increase Viewing Angles

The traditional approach to increasing viewing angle is to add a compensation film to the front of a display. Compensation film works fairly well, but only gets to about 140 x 120 degrees. The simplest alternative solution is IPS or S-IPS which uses lateral electric fields applied within the cell structure. IPS requires higher driving voltages that limit the temperature range of operation. PVA (Patterned Vertical Alignment) Technology from Samsung is another approach that has high contrast, but slowed response time. Sharp Advanced Super View Technology provides the best overall performance.
