    摘要: A liquid crystal display device significantly reduces power consumption and causes no signal delay when a liquid crystal panel performs an inversion-type drive. The liquid crystal display device comprises a digital controller, a level shift circuit, a digital-to-analog (D/A) converter, a liquid crystal panel, and a plurality of capacitors. In the D/A converter, a charging control circuit is provided corresponding to each capacitor. The charging control circuit comprises a switch, a diode and an inverter, the switch and the diode being coupled in parallel. The switch is turned on and off in response to a switching signal from the digital controller. The switch is changed to a turning- on state during a blanking period after one horizontal displaying. Upon turning-on of the switch, the capacitors are charged. Digital pixel data outputted from the digital controller undergoes a level changing depending on a voltage across the electrodes of the capacitors, according to a charge conservation.

    摘要: First and second resistor series divide a predetermined voltage range to generate first reference voltages and second reference voltages, respectively. First and second switch controlling circuits select respective ones of the first reference voltages and the second reference voltages. A comparing unit generates a logical signal representing a logical value by comparing a combined transistor current based on the selected first and second reference voltages with a transistor current based on an input signal. The first switch controlling circuit specifies two adjacent first reference voltages where the logical value is inverted by sequentially selecting the first reference voltages, and determines to select one of the adjacent reference voltages. Te second switch controlling circuit specifies two adjacent second reference voltages where the logical value is inverted by sequentially selecting the second reference voltages, and determines to select one of the adjacent reference voltages.
