Abstract
A vertical drive circuit comprises a shift circuit composed of a plurality of cascaded half-bit scan circuits, a plurality of NAND gate circuits controlled by output signals of the scan circuits and control signals, and a plurality of output buffer circuits connected to the NAND gate circuits. A horizontal drive circuit comprises a shift circuit composed of a plurality of cascaded half-bit scan circuits, a plurality of first NAND gate circuits controlled by output signals of the scan circuits and control signals, a plurality of second NAND gate circuits controlled by output signals of the first NAND gate circuits and enable signals, and a plurality of data sampling and holding circuits controlled by output signals of the second NAND gate circuits.
