摘要： An optical sensing circuit includes a capacitor, and a light sensing unit, a compensation unit, and a switching element coupled to the capacitor. The light sensing unit includes a first light sensing transistor for sensing a first color. The compensation unit includes a second light sensing transistor for sensing a second color. The spectra of the second color and the first color do not overlap each other. When the light illuminates, the light sensing unit generates a first current and the compensation unit generates a second current. The second current reduces the magnitude of the charging or discharging current when the capacitor is charged or discharged by the first current. When the switching element turned on, the voltage of the capacitor is read to determine the color of the light. The voltage level of the gate of the first or second light sensing transistor is adjustable.

摘要： In an exemplary flat display apparatus and control circuit and method for controlling the flat display apparatus, the flat display apparatus includes a plurality of gate driving units, each of which controls the operation of a scan line in the flat display apparatus. The flat display apparatus provides a first gate high level voltage signal and a second gate high level voltage signal to the gate driving units such that the first and second gate high level voltage signals are used as voltage signals transmitted to corresponding scan lines. The first and second gate high level voltage signals respectively include a falling edge with a slope. Duration time of the falling edge of the first gate high level voltage signal is longer than that of the falling edge of the second gate high level voltage signal.
