Summary:Described herein are systems and methods for the reduction of power consumption and mitigation of device stress accumulation in low frequency refreshed Liquid Crystal Displays (LCDs). In an exemplary embodiment, two or more transistors in series are used to hold charge on an LCD pixel. To prevent negative stress on the transistors, the transistors are alternately driven to an "on" state so that no one transistor sees a long "off" time. In another embodiment, circuits and signaling waveforms for performing frame writing and stress mitigation are provided that minimize dynamic power consumption and static power consumption in peripheral ESD circuits.
