Document Type and Number:
Japanese Patent JP4446392
Kind Code:
B2
Abstract:
Provided is a scan driver that supplies a scan signal to an organic light emitting display device (OLED). The scan driver includes transistors of the same conductivity type. To generate individual scan signals, the scan driver includes samplers, each of which samples an input signal in synchronization with a clock signal or an inverted clock signal; and an OR gate and a NAND gate, each of which performs a logical operation on output signals of adjacent samplers and generates a scan signal. The samplers, the OR gate and the NOR gate include transistors of the same conductivity type.
