ABSTRACT:
The present invention relates to a signal driver circuit for driving a liquid crystal display panel. The signal driver circuit provides level shifting within the circuit to lower the power consumption of a liquid crystal display module while still providing a wide analog voltage range to the liquid crystal display elements. Furthermore, reference voltages are provided to decoding circuits by using distributed resistors. The decoding circuits utilize a cell layout that allows data to bused into the cell through polysilicon that also operates as the gate of the decode input transistors. The decode input transistors are arranged in strands of abutting transistors which may be connected in series or in parallel. Moreover, the decode cell input transistors may all be of the same conductivity type.
