DRIVING METHOD FOR DISPLAY AND DISPLAY

摘要

A display comprises a liquid crystal display panel having a first substrate on which a plurality of scan electrodes are formed, a second substrate on which a plurality of data electrodes are formed, and a liquid crystal layer, a scan electrode drive circuit for applying a scan pulse composed of a combination of varying voltage levels with selection and non-selection to the scan electrodes, a data electrode drive circuit for applying a data pulse composed of a combination of varying voltage levels with writing data to the data electrodes in response to the scan pulse, and a drive control circuit for supplying a pulse control signal for controlling the polarity of the scan pulse and the data pulse. The scan electrode drive circuit and the data electrode drive circuit control the polarity of the scan pulse and the data pulse to the voltage level corresponding to the pulse control signal. The drive control circuit inverts or non-inverts the phase of the pulse control signal according to the result of the comparison of the number of changes with the number of no-changes in the writing data for each period in which the scan pulse is applied.
