We performed a complete study of optical properties of MTN mode LCOS with in‐plane retarders. A new fast response and compensated MTN configuration is proposed. The on/off axis contrast of the new compensated LCOS panel can be dramatically improved from 800:1 to over 1500:1. When such fast response (<170 s) compensated MTN mode equip with analog driving LCOS backplane, 95% NTSC is recorded even under 100% LED turn on duty.

A new configuration called stressed splay twist (SST) mode is proposed. Such device has much stronger transient effect than conventional TN mode. By using this dynamic approach, the true steady state-to-steady state response time of the liquid crystal can be ignored. The transient response time is used, in conjunction with the pulsed light source. A QVGA FSC displays prototype using SST mode is demonstrated.
