ABSTRACT:
Embodiments of a scan driver capable of freely adjusting the width of emission control signals are disclosed. One embodiment of the scan driver comprises a shift register configured to sequentially shift a start pulse in response to a clock signal to generate sampling pulses, a NOR gate coupled to each emission control line and configured to generate emission control signals in response to at least two sampling pulses, and a NAND gate coupled to each scan line to generate scan signals in response to at least two sampling pulses. At least one of the two sampling pulses input to the NAND gate is input via an inverter. The width of the start pulse is thus controllable to freely adjust the width of the emission control signals. Accordingly, the brightness of an organic light emitting display employing the scan driver can be freely adjusted.
