Patent ID: 8766907

Claim:
A drive control method comprising: generating a first transmission clock signal having a first transmission clock frequency; supplying the first transmission clock signal to a first data driver that is configured to output drive signals to display elements included in a first one of divided drive regions in a display panel; generating a second transmission clock signal having a second transmission clock frequency that is different from the first transmission clock frequency; supplying the second transmission clock signal to a second data driver that is configured to output drive signals to display elements included in a second one of the divided drive regions in the display panel; generating a reference clock signal having a clock frequency different from the first and second transmission clock frequencies; generating a common drive-start control signal based on the reference clock signal; supplying the generated common drive-start control signal to the first and second data drivers; and controlling each of the first and second data drivers to start outputting the drive signals to the display elements included in the first and second divided drive regions at a same timing in response to the supply of the common drive-start control signal.
