Abstract
An integrated circuit device includes: a timing information storage section that stores phase length information in correspondence with an index number; a waveform information storage section that stores waveform information related to a plurality of drive waveforms used in response to at least one display state; a timing control section that reads an index number included for each phase in the waveform information, reads phase length information corresponding to the index number from the timing information storage section, and sequentially generates a selection signal during a drive voltage application period corresponding to a plurality of phases; and a drive waveform selection section that selects a waveform value representing a drive voltage, out of a plurality of units of waveform information stored in the waveform information storage section, in accordance with the selection signal.
