    摘要: An amplifier and a display driving circuit. The amplifier includes an input stage, a bias stage and an output stage. The input stage determines voltage levels of two nodes in correspondence to two input voltages received in response to a first bias voltage, and includes four path selecting switches, two input transistors and one bias transistor. The bias stage generates two class AB output voltages which correspond to the voltage levels of the two nodes, and includes current mirrors, ten path selecting switches, class AB bias circuits and two bias transistors. The output stage generates an output voltage VOUT that corresponds to the two class AB output voltages, and includes two coupling capacitors and two push-pull transistors. The plurality of path selecting switches operate by one signal of a first path selecting signal and a second path selecting signal that are exclusively enabled with respect to each other.

    摘要: A display driving circuit and method is capable of minimizing the residual image of a display panel as well as consumption electric current. The display driving circuit generates driving signals corresponding to valid data and black data and transmits the driving signals to a display panel, and includes N data selection switches (where N is the integer), N buffers, N buffer output selection switches, and multiple charge sharing switches. The N data selection switches select one of the valid data and the black data. The N buffers buffer the signal selected by the respective data selection switches. The N buffer output selection switches switch outputs of the buffers to output the respective driving signals. The multiple charge sharing switches connect the neighboring pairs of the driving signals.
