Zusammenfassung:	PURPOSE: A sensor scan driver and a flat panel display with a built-in touch screen having the same are provided to improve photosensitivity through photodiodes. CONSTITUTION: A shift register unit(510) sequentially generates sensor scan signals to drive a plurality of photodiodes, and a transfer gate unit(520) converts a voltage range of the generated sensor scan signal. A buffer unit(530) supplies the sensor scan signal to the photodiodes. At a first transfer age, a positive control electrode receives an output signal of the shift register unit.
