摘要： A signal driver IC (or a display driver circuit in a broad sense) includes a signal electrode driver circuit which drives a signal electrode by using grayscale data. The signal electrode driver circuit has a precharge circuit, a DAC circuit, and a drive voltage adjusting circuit. The precharge circuit sets an output electrode connected to the signal electrode at a precharge voltage in a first stage which is a first period within one horizontal scanning period. In a second stage subsequent to the first stage, the DAC circuit sets the output electrode at a reference voltage based on the grayscale data. In a third stage subsequent to the second stage, the drive voltage adjusting circuit adjusts the voltage of the output electrode by using the grayscale data.

摘要： In the case of supplying voltage to a common electrode which faces a pixel electrode through electro-optical substance while changing the voltage from a first low-potential-side voltage to a first high-potential-side voltage, a second high-potential-side voltage, which is higher than the first high-potential-side voltage, is supplied to the common electrode instead of the first low-potential-side voltage, and the first high-potential-side voltage is then supplied to the common electrode. One of the first high-potential-side voltage and a first intermediate voltage, which is lower than the first high-potential-side voltage but higher than the first low-potential-side voltage, may be supplied to the common electrode before supplying the second high-potential-side voltage to the common electrode.

摘要： A display drive apparatus for driving liquid crystals by applying a voltage to the liquid crystals based on gray-scale data representative of a display. The display drive apparatus includes a polarity control circuit, an input selection circuit, a non-linear operation region identifying circuit and an offset current generation circuit. The polarity control circuit generates a polarity control signal based on a polarity signal. The input selection circuit selects a predetermined reference voltage for driving the liquid crystals from a plurality of reference voltages provided from an input voltage generation circuit or a plurality of reference voltages generated within the input selection circuit based on an input signal representative of gray-scale data and the polarity control signal. The non-linear operation region identifying circuit identifies a non-linear operation region in which an output signal from an operational amplifier does not follow an input thereto based on the input signal and the polarity control signal, and outputs an offset current generation control signal for supplementing the current of the output signal of the operational amplifier when an input voltage in the non-linear operation region is subjected to an operation amplification. The operational amplifier inputs the predetermined reference voltage selected by the input selection circuit and outputs at an output terminal an output signal that is operation-amplified according to the predetermined reference voltage. The offset current generation circuit supplements the current at the output terminal of the operational amplifier based on the offset current generation control signal outputted from the non-linear operation region identifying circuit.
