1. A method comprising:
updating, by a processor, a highest grayscale value associated with a raw image data to a maximum grayscale value;
determining an expansion ratio based on the highest grayscale value and the maximum grayscale value;
modifying at least one grayscale value associated with the raw image data prior to display at a display panel, wherein the modifying of the at least one grayscale value is based on the expansion ratio; and
adjusting a backlight intensity based on a quotient of the highest grayscale value divided by the maximum grayscale value, wherein the quotient is raised to a power of a gamma correction curve value to adjust a pixel transmittance of the display panel.
