  • Display device to respond to a command to display a still image or video image and method for controlling the same
    Patent number: 9934755
    Abstract: A display device which may operate as a reflective display device which uses external light without separate power supply at an illumination level equal to or greater than a certain illumination level, and which may operate as a transmissive display device which uses internal light at an illumination level less than the certain illumination level to provide a clear image in an outdoor environment and a dark indoor environment. Power consumption may be minimized by automatically switching the display mode depending on the illumination level.
