摘要： A flat panel display (FPD) with a photo sensor type built-in touch screen capable of performing a scan operation. The FPD with the built-in touch screen includes a plurality of unit pixels disposed in a display region of the FPD and arranged in pixel groups and photo sensors adjacent to the unit pixels of the respective pixel groups. In a scan operation mode, the plurality of unit pixels in each of the pixel groups sequentially emit light to perform a scan operation using the light emitted from the unit pixels and reflected by a scan object to be scanned to be incident on the photo sensors.
