摘要:
A driving apparatus comprises a driving unit and a drive voltage generating unit. The driving unit includes a scanning electrode driver and a data electrode driver for driving an electrode matrix formed of scanning electrodes and data electrodes. The drive voltage generating unit includes a first means for generating a fixed voltage, a second means for generating a source voltage for providing drive voltages for driving the electrode matrix, and a third means for generating a first voltage equal to a subtraction of the fixed voltage from the source voltage and a second voltage equal to a subtraction of the source voltage from the fixed voltage. The first and second voltages are preferably controlled so as to vary depending on an external temperature.
