A display device, comprising: a display panel; a driver configured to drive the display panel based on a video signal; and a detector configured to obtain a first detection value by detecting reflective light from a reflective media, which occurs when ambient light is irradiated to the reflective media, while obtaining a second detection value by detecting reflective light from the reflective media, which occurs when the display panel irradiates display light to the reflective media.

Display device and display method

A display device includes a display panel, a driver, a detector, and an acquisition part. The driver drives the display panel based on a video signal. The detector obtains a first detection value by detecting reflective light from reflective media, which occurs when ambient light is irradiated to reflective media, while obtaining a second detection value by detecting reflective light from reflective media, which occurs when the display panel irradiates its display light to reflective media. The driver corrects a drive value for the display panel such that the second detection value approaches the first detection value or such that the chromaticity represented by the second detection value approaches the chromaticity represented by the first detection value, and therefore the acquisition part acquires information concerning the color temperature of ambient light based on the corrected drive value.

A display device includes a display panel body that has a display surface emitting light, and a brightness sensor unit that is fixed on the display surface of the display panel body and includes a brightness sensor detecting a brightness of the light from the display surface.
