摘要:
An amplifier and a driving device of a display device using the same reduce a size of the whole circuit by reducing the number of input transistors. An input unit(810) is connected between a first power source supplying the first voltage and a second power source supplying the second voltage. An input unit receives the first input signal and the second input signal and is controlled according to the first and second input signals. A bias unit(820) receives a bias voltage for operating the input unit and includes a first node and a second node controlled by the input unit. A first output transistor is turned on and off according to the signal applied to the first node. A second output transistor is turned on and off according to the signal applied to the second node. An output unit(830) applies an output voltage to a pixel by using the first output transistor and the second output transistor.
