Patent ID: 8704813

Claim:
An integrated circuit device comprising: a drive voltage output section which outputs a drive voltage to be supplied to a segment electrode of an electro-optical panel; a display data storage section which stores at least first display data and second display data; and a drive waveform information output section which outputs drive waveform information in changing of a display state at the segment electrode from a first display state corresponding to the first display data to a second display state corresponding to the second display data, wherein the drive waveform information output section has a first storage section which stores the drive waveform information for each of basic periods T 1 to TM (M is an integer of 2 or more), wherein the drive waveform information includes the lengths of the periods of the each of basic periods T 1 to TM according to the type, operation environments, and the like of the electro-optical panel, an output section which outputs the drive waveform information corresponding to each period specified by the basic periods T 1 to TM, and the drive voltage output section outputs the drive voltage specified by the first display data and the second display data from the display data storage section and the drive waveform information from the drive waveform information output section, wherein the drive waveform information includes N×N (N is an integer of 2 or more) drive waveform signals SWV ( 1 , 1 ) to SWV (N, N), the first storage section has registers RT 1 to RTM (M is an integer of 2 or more) corresponding to the basic periods T 1 to TM, respectively, and the register RTk (1≦k≦M) of the registers RT 1 to RTM stores a register value specifying signal levels of the drive waveform signals SWV ( 1 , 1 ) to SWV (N, N) in the basic period Tk of the basic periods T 1 to TM.
