Abstract: A display device supports a variable frame mode where each frame includes a variable blank period. The display device includes a display panel including a plurality of pixels, a backlight unit configured to generate light, a panel driver configured to drive the display panel, a backlight controller configured to drive the backlight unit, and a blank counter configured to count a time of the variable blank period. The backlight controller controls the backlight unit to increase an intensity of the light generated by the backlight unit as the counted time of the variable blank period increases.
