Abstract
A display device is provided, which includes a display, a ditherer configured to perform dithering of video data displayed on the display, an illumination sensor configured to sense illumination around the display device, and a processor configured to control driving of the ditherer on the basis of a grayscale level of the video data if or when the sensed illumination is lower than a predetermined value.
Claims20
A display device, comprising:
- a display comprising a plurality of Light Emitting Diodes (LEDs);
- an illumination sensor configured to sense illumination around the display device;
- and
- a processor configured to, based on an image being received, control the display to display the image by performing dithering based on the sensed illumination around the display device and a grayscale level of the image,
- wherein the processor is configured to:
- based on the sensed illumination around the display device being lower than a predetermined value, identify at least one area with a grayscale level being lower than a predetermined level from among a plurality of areas of the image,
- control the display to display the image using at least one LED corresponding to the identified area without performing the dithering, and
- control the display to display the image by performing the dithering using remaining LED among the plurality of LEDs.
A method for controlling a display device, comprising:
- sensing illumination around the display device comprising a plurality of Light Emitting Diodes (LEDs);
- based on the sensed illumination around the display device being lower than a predetermined value, identify at least one area with a grayscale level being lower than a predetermined level from among a plurality of areas of an image;
- displaying the image using at least one LED corresponding to the identified area without performing dithering;
- and
- displaying the image by performing the dithering using remaining LED among the plurality of LEDs.
A non-transitory computer readable storage storing a method for controlling a display device, the method comprising:
- sensing illumination around the display device comprising a plurality of Light Emitting Diodes (LEDs);
- based on the sensed illumination around the display device being lower than a predetermined value, identify at least one area with a grayscale level being lower than a predetermined level from among a plurality of areas of an image;
- displaying the image using at least one LED corresponding to the identified area without performing dithering;
- and
- displaying the image by performing the dithering using remaining LED among the plurality of LEDs.
