Thus an overall height of the backlight module is shortened. The reduced overall length and height of the backlight module makes it compact.

Abstract: A mechanical roller controller is installed on a substrate. Two switches, which are secured on the substrate, send digital signals when they are pressed. A base is disposed on the substrate. Two pedals are installed on the base and near the two switches, and each pedal is pivotally connected with the base. A roller, having two gears, is mounted on the base. A first gear is positioned within reach of the two pedals. A second gear is designed for users to take control by their fingers. When the second gear rotates, the first gear rotates simultaneously. Two pedals, driven by the first gear, move along opposite directions. One of the two pedals moves downward to press the switch and returns to its original position by being pushed back by the switch.
