摘要： A liquid crystal display device includes a drain drive circuit for driving drain signal lines of a liquid crystal display panel. The drain drive circuit receives a plurality of grey-scale reference voltages from an external circuit, interpolates a plurality of intermediate voltages between each pair of adjacent ones of the grey-scale reference voltages, selects voltages from the grey-scale reference voltages and the intermediate voltages, and applies the selected voltages to the drain signal lines. V0 is a grey-scale reference voltage corresponding to a minimum grey-scale level, Vm is a grey-scale reference voltage corresponding to a maximum grey-scale level, and Vi is a grey-scale reference voltage that is nearest to a voltage level (Vm+V0)/2. A number of intermediate voltages interpolated between V(i-1) and Vi is greater than both a number of intermediate voltages interpolated between V0 and V1, and a number of intermediate voltages interpolated between V(m-1) and Vm.

摘要： On an interface of a liquid crystal display device, which converts the number of pixels of image signals inputted from an external signal source, such as a host computer, into image signals having a smaller number of pixels and fetches the image signs into drain drivers at double edges of a clock signal of low frequency, a clock surveillance unit is mounted, which includes a clock synthesizer and a clock comparator circuit, and which detects the presence or the absence of an irregularity in the timing of a pixel clock signal inputted from the external signal source and outputs a determination of the normal/irregular status of the pixel clock signal. When it is determined that the pixel clock signal is irregular, the supply of image data to the drain drivers from a parallel-serial converter is stopped, so that the generation of an irregularity in the display produced by the liquid crystal display device can be obviated.

Each of the pixels includes a pixel electrode, and a thin-film transistor having a gate electrode and a drain electrode.

Drain signal lines arranged in the columns are connected to the drain electrodes of the thin-film transistors. The liquid crystal display device further includes a gate drive circuit for driving the gate signal lines, and a drain drive circuit for driving the drain signal lines. The drain drive circuit receives a plurality of grey-scale reference voltages from an external circuit, interpolates a plurality of intermediate voltages between each pair of adjacent ones of the grey-scale reference voltages, selects voltages from the grey-scale reference voltages and the intermediate voltages, and applies the selected voltages to the drain signal lines.
