Abstract
The present application provides a demux control circuit. The demux control circuit includes a driving chip, a logic circuit, and a demux for providing two or three pulse signals to the logic circuit, the logic circuit including a plurality of NOR Gate and a plurality of buffers which can convert two pulse signals into three control signals or convert the three pulse signals into four control signals through the cooperation of the NOR gates and the buffers to achieve outputting a larger number of control signals by a smaller number of pins, thereby reducing the number of pins outputted from the driving chip and reduce production costs.
