A novel frame buffer pixel circuit was developed which acquires low power inside a pixel. The function timing and power of this novel pixel circuit was evaluated by SPICE simulation. A voltage comparator embedded in a pixel compares the adjacent frame data voltage by which the intelligent discharge operation was realized. This intelligent discharge operation lowers the power dissipation in LCoS backplane.
