ABSTRACT:
A scan driver that selectively performs progressive scanning and interlaced scanning and a display using the same. The scan driver includes a shift register having a plurality of flip-flops arranged in series, an odd line selection unit having a plurality of NAND gates, and an even line selection unit having a plurality of NAND gates. In response to an odd line control signal and an even line control signal input to the odd line selection unit and the even line selection unit, respectively, the scan driver performs progressive scanning or interlaced scanning. The scan driver may also include a mode selection unit to selectively perform progressive scanning or interlaced scanning in response to a mode selection signal.
