Abstract
A detection device includes a plurality of detection elements arranged in a matrix having a row-column configuration in a detection area, a plurality of scan lines each coupled to the detection elements arranged in a first direction, a drive circuit configured to drive the scan lines, a plurality of output signal lines each coupled to the detection elements arranged in a second direction different from the first direction, and a detection circuit configured to be supplied with detection signals from the detection elements through the output signal lines.
Claims18
A detection device comprising:
- detection elements;
- reset control scan lines each coupled to a first group of the detection elements that are arranged in a first direction;
- a drive circuit configured to drive the reset control scan lines;
- output signal lines each coupled to a second group of the detection elements that are arranged in in a second direction different from the first direction;
- and
- a detection circuit configured to receive detection signals from the detection elements through the output signal lines, wherein
- each of the reset control scan lines is configured to supply a reset control signal to the first group of the detection elements, and
- the drive circuit comprises:
- a first transistor configured to apply a first potential to a corresponding one of the reset control scan lines;
- a second transistor that is coupled in series to the first transistor, and is configured to apply a second potential lower than the first potential to the corresponding one of the reset control scan lines;
- and
- a third transistor that is coupled in parallel to the second transistor, and is configured to apply the second potential to the corresponding one of the reset control scan lines.
