    摘要: First and second input/output circuits each have an input terminal connected to the input node. A first power supply wiring supplies a first voltage. A second power supply wiring supplies a second voltage. The first and second input/output circuits each select any one of the first and second power supply wirings, depending on the polarity of an input signal, to output an output signal. The first and second input/output circuits each have any one of a first characteristic in which an output signal having the same polarity as that of the input signal is output and a second characteristic in which an output signal having a polarity opposite to that of the input signal is output. The characteristics possessed by the first and second input/output circuits are different from each other.

    摘要: Each of first and second decoders outputs two voltages each having a voltage value equal to any one of a plurality of gray-level voltages according to gray-level data as two selection voltages or outputs any two of the plurality of gray-level voltages according to gray-level data as the two selection voltages. A connection switching circuit associates one of the first and second decoders with a first differential amplifier and the other decoder with a second differential amplifier. An output switching circuit associates one of the first and second differential amplifiers with a first output node and the other differential amplifier with a second output node. Each of the first and second differential amplifiers synthesizes selection voltages output from the decoder associated with the differential amplifier to generate a driving voltage and outputs the generated driving voltage to the output node associated with the differential amplifier.

    摘要: In a forward-direction fetching operation mode, each of display panel drive devices other than a last display panel drive device fetches display data upon the reception of a start signal. In the forward-direction fetching operation mode, the last display panel drive device fetches the display data upon the reception of the start signal. In a reverse-direction fetching operation mode, each of the display panel drive devices other than the last display panel drive device transmits the start signal to the immediately subsequent device in the forward direction upon the reception of the start signal. In the reverse-direction fetching operation mode, the last display panel drive device fetches the display data and transmits an enable signal to the immediately preceding device in the reverse direction upon the reception of the start signal. In the reverse-direction fetching operation mode, the display panel drive devices other than the last device fetches the display data and transmits the enable signal to the immediately preceding device in the reverse direction upon the reception of the enable signal.
