Classification: CPC G  H | IPC G

Claim 7:
8. A method comprising:
generating, with a ramp signal generating circuit of a source driver, a first portion of a ramp signal within a first horizontal scanning period;
supplying, with a first switch circuit of the source driver, a first video signal to a first data line of a plurality of data lines by holding a voltage as of a time point when the first data line and an output of the ramp signal generating circuit are switched from a connected state to a disconnected state, the first video signal based on the first portion of the ramp signal, and the first data line electrically connected to a first plurality of display elements;
generating, with the ramp signal generating circuit of the source driver, a second portion of the ramp signal within a second horizontal scanning period that is different from the first horizontal scanning period; and
supplying, with a second switch circuit of the source driver, a second video signal to a second data line of the plurality of data lines by holding a second voltage as of a second time point when the second data line and the output of the ramp signal generating circuit are switched from a connected state to a disconnected state, the second video signal based on the second portion of the ramp signal, and the second data line electrically connected to a second plurality of display elements.
