1. A display device comprising:
a host which transmits high dynamic range image data through a first interface and a second interface; and
a display driver integrated circuit comprising:
a first interface unit which receives a first signal of the high dynamic range image data through the first interface; and
a second interface unit which receives a second signal of the high dynamic range image data through the second interface, the second interface being different from the first interface,
wherein the second signal includes metadata of the high dynamic range image data which is not defined in a mobile industry processor interface scheme,
wherein the display driver integrated circuit receives the high dynamic range image data from the host,
wherein the first interface is a mobile industry processor interface, and
wherein the second signal includes at least one of a set value for tone mapping, a set value for determining a color gamut and remapping colors, a maximum-luminance set value of an image, and a minimum-luminance set value of an image.
