The backlight illuminates the video display module. The first backlight controller controls the amount of light emitted by the backlight based on the left-eye video frame, while the second backlight controller controls the amount of light based on the right-eye video frame. The signal converter merges left-eye and right-eye video backlight control signals arranged in order to generate a new backlight control signal.
