Assignee: JAPAN DISPLAY INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 0:
1. A display device, comprising:
a display panel having a display region in which a plurality of pixels are provided;
a plurality of temperature sensors; and
a control integrated circuit (IC) configured to control operations of the display panel and the temperature sensors,
wherein
a plurality of temperature detection regions in which the temperature sensors are arranged are provided to overlap the display region,
the display region has a plurality of partial regions that overlap the temperature detection regions, respectively,
the control IC is provided capable of controlling the display region on a partial region basis,
at least either signal lines of the display panel or scan lines of the display panel, and the temperature sensors are coupled to the control IC,
the control IC includes:
a display controller configured to control the operation of the display panel;
a temperature detection controller configured to perform processing related to the operation of the temperature sensors; and
a light source controller configured to control the operation of a light source device that illuminates the display panel, and

when a temperature equal to or higher than a first temperature is detected in one of the temperature detection regions, the temperature detection controller performs temperature detection on the one temperature detection region in a blanking period in which no images are displayed by the display panel and in a write period in which pixel signals are written to the pixels.
