    Abstract: A head mounted display device includes: a display module displaying an image; a calculator including an adaptive luminance calculator that scans a first image based on a predetermined viewing angle and calculates a first adaptive luminance of the first image, and a discomfort luminance calculator that calculates a first discomfort luminance based on the first adaptive luminance according to an equation that models a relationship between the first adaptive luminance and the first discomfort luminance at which a user perceives discomfort; and a luminance controller that controls a dimming level of the display module to be equal to or less than the first discomfort luminance.

    Abstract: A display device includes a display panel including a pixel that includes sub-pixels for emitting light in respective colors, and a driver configured to adjust a current amount flowing through the sub-pixels and to adjust an emission duty of the sub-pixels, drive one sub-pixel among the sub-pixels having a luminance with a first current amount and with a first emission duty when a color coordinate of an image expressed by the pixel is within a reference color space, and drive the one sub-pixel having the luminance with a second current amount that is greater than the first current amount and with a second emission duty that is less than the first emission duty when the color coordinate is outside of the reference color space.
