Assignee: JAPAN DISPLAY INC.
Field: Computer technology (Electrical engineering)
Classification: CPC H  A  G | IPC G  H

Claim 0:
1. A detection device comprising:
a sensor base;
a plurality of photoelectric conversion elements that are provided in a detection area of the sensor base and are configured to receive light incident thereon and output signals corresponding to the received light;
a plurality of switching elements provided in the respective photoelectric conversion elements;
a plurality of gate lines that are coupled to the switching elements and extend in a first direction;
a first light source configured to emit first light having a first maximum emission wavelength; and
a second light source configured to emit second light having a second maximum emission wavelength,
wherein
the detection area has a first detection area and a second detection area adjacent to each other in a second direction intersecting the first direction,
the first light source and the second light source are arranged in the second direction along an outer circumference of the detection area,
the first light source is provided in a position corresponding to the first detection area and is configured to emit the first light in a direction parallel to the first direction,
the second light source is provided in a position corresponding to the second detection area and is configured to emit the second light in the direction parallel to the first direction, and
the detection device further comprises a gate line drive circuit configured to
sequentially supply drive signals to the gate lines provided in the first detection area in a first scan direction and
sequentially supply the drive signals to the gate lines provided in the second detection area in a second scan direction opposite to the first scan direction.
