Abstract:
A programmable level shifter for providing upshifted control signals to an active matrix display based on logic-level control signals received from a timing controller. The programmable level shifter includes a programmable state machine, level-shifting output drivers, and a programming interface. The programmable state machine is configured to receive at least one control signal from a timing controller. The state machine generates, based on said at least one control signal, a plurality of outputs for driving gate drivers of the active matrix display. The level-shifting output drivers convert the plurality of outputs generated by the programmable state machine to a higher-magnitude voltage level. The programming interface facilitates the programming of aspects of the programmable state machine.
