Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 12:
13. An electronic apparatus comprising:
a display device including
display elements arranged in a two-dimensional matrix in a first direction and a second direction different from the first direction;
data lines provided for respective display element columns arranged along the second direction; and
a source driver that supplies a video signal voltage to the data lines,
wherein a display element row arranged along the first direction includes a display element belonging to a first group and a display element belonging to a second group different from the first group,
the source driver comprises a ramp signal generating circuit and a switch circuit that causes a data line to hold a voltage as of a time point when the data line and output of the ramp signal generating circuit are switched from a connected state to a disconnected state,
the ramp signal generating circuit generates, within one horizontal scanning period, at least a ramp signal used for setting a video signal voltage to a display element belonging to the first group and a ramp signal used for setting a video signal voltage to a display element belonging to the second group, and
when output of the ramp signal generating circuit and a data line are switched from the connected state to the disconnected state in order to cause the data line corresponding to a certain display element to hold a video signal voltage, output of the ramp signal generating circuit and a data line corresponding to a display element belonging to a group different from the group, to which the certain display element belongs, are switched from the disconnected state to the connected state.
