DRIVER FOR DISPLAY DEVICE

PROBLEM TO BE SOLVED: To provide a driver for a display device of which the variance between outputs is suppressed. SOLUTION: The driver for a display device is equipped with a 2nd MOSFET 19 and a 3rd MOSFET 21 which supply mutually equal reference currents, a 1st current input MOSFET 10 which is co...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a driver for a display device of which the variance between outputs is suppressed. SOLUTION: The driver for a display device is equipped with a 2nd MOSFET 19 and a 3rd MOSFET 21 which supply mutually equal reference currents, a 1st current input MOSFET 10 which is connected to the 2nd MOSFET 19, a 2nd current input MOSFET 12 which is connected to the 3rd MOSFET 21, a plurality of current mirrors which are arranged between the 1st current input MOSFET 10 and the 2nd current input MOSFET 12 and distribute currents inputted to the 1st current input MOSFET 10 and 2nd current input MOSFET 12 and a current adding means for varying an output current value by adding currents generated by the plurality of current mirrors.
