Patent ID: 8199094

Claim:
A display device, comprising: a liquid crystal display panel, having a first substrate on which are formed a plurality of scanning electrodes extending in a first direction, a second substrate on which are formed a plurality of data electrodes extending in a second direction different from the first direction, and a liquid crystal layer formed between the first and second substrates; a scanning electrode driving circuit which applies, to the plurality of scanning electrodes, scan pulses having combinations of different voltage levels according to whether a scanning electrode is selected or unselected; a data electrode driving circuit which applies, to the plurality of data electrodes, data pulses having combinations of different voltage levels according to write data, corresponding to the scan pulses; and a driving control circuit which supplies, to the scanning electrode driving circuit and data electrode driving circuit, pulse control signal which controls the voltage levels of the scan pulses and data pulses; wherein the scanning electrode driving circuit and data electrode driving circuit respectively control the scan pulses and data pulses at voltage levels according to the pulse control signal, and the driving control circuit inverts or does not invert the phase of the pulse control signal, at each application interval of the scan pulses, according to a relation between the number of changed values and the number of unchanged values of the write data.
