Abstract
A display device according to an embodiment of the present disclosure may comprise a display panel; a backlight including a plurality of light sources that provide light to the display panel; and a controller configured to: obtain a illuminance and image information of an input image, increase a tone intensity of a low gray-level area of the input image based on the image information when the illuminance is less than a reference value, and control the backlight so that a current flowing in light sources corresponding to the low gray-level area is reduced.

A display device, comprising:
- a display panel;
- a backlight including a plurality of light sources that provide light to the display panel;
- and
- a controller configured to:
- obtain a illuminance and image information of an input image,
- increase a tone intensity of a low gray-level area of the input image based on the image information when the illuminance is less than a reference value, and
- control the backlight so that a current flowing in light sources corresponding to the low gray-level area is reduced.
A method of operating a display device, comprising:
- obtaining a illuminance and image information of an input image;
- increasing a tone intensity of a low gray-level area of the input image based on the image information when the illuminance is less than a reference value;
- and
- controlling the backlight so that a current flowing in light sources corresponding to the low gray-level area is reduced.
A non-transitory computer-readable recording medium on which a program for performing a method of operating a display device is recorded,
- wherein the method comprises:
- obtaining a illuminance and image information of an input image;
- increasing a tone intensity of a low gray-level area of the input image based on the image information when the illuminance is less than a reference value;
- and
- controlling the backlight so that a current flowing in light sources corresponding to the low gray-level area is reduced.
