Abstract

In this paper, we propose two novel pixel circuits which are able to provide great picture quality at oblique viewing angles. These two pixel circuits are based upon the VA-IPS mode with vertically aligned nematic liquid crystals and in-plane switching electrodes. Comparing to current VA-type LCDs, the VA-IPS mode can be used to improve oblique gamma distortion with its tone rendering distortion index (TRDI) as low as 0.15. With the proposed pixel circuits, we believe the TRDI can be further improved to be less than 0.13. The novel technologies are very likely to be the solution for VA-type LCDs when facing the competition from other display technologies.
