Abstract: A display device includes: a display which includes a display screen on which a video is displayed; a decorative sheet disposed on a display screen side of the display, is larger than the display screen in a front view of the display screen, and covers the display screen, the decorative sheet including a first region which overlaps with the display screen in the front view and a second region which does not overlap with the display screen in the front view; and a controller which controls a luminance of the video that is displayed by the display, based on (i) an illuminance of ambient light around the display and the decorative sheet and (ii) first information indicating a relationship between the illuminance and appearances of a third region corresponding to a black display region of the video in the first region and the second region on the decorative sheet.

Abstract: Includes electric motor (330) driving driving wheel (610) , speed control unit (300) controlling driving of electric motor (330) based on instructed speed ωr*, brake control unit (400) controlling hydraulic brake (500) applying mechanical braking to an electromotive vehicle, speed sensor (340) detecting traveling speed ωr of the electromotive vehicle, and determination unit (200) determining whether the mechanical braking needs to be applied in response to the difference between instructed speed ωr* and traveling speed ωr, and controlling operation of brake control unit (400) based on the determination result. Determination unit (200) determines that mechanical braking needs to be applied when instructed speed ωr* indicates deceleration and traveling speed ωr is higher than instructed speed ωr* , and performs control so that brake control unit (400) works hydraulic brake (500).
