Abstract
An illuminated trackpad includes a substrate, a light guide plate disposed under the substrate, a circuit board disposed under the light guide plate, and light-emitting elements disposed on the circuit board. The light guide plate includes light guide units and through holes. Each light guide unit is composed of light guide microstructures and substantially in the shape of a strip or a line. The through holes are respectively arranged on one side of the light guide units. The circuit board has a touch surface and a non-touch surface. The touch surface has a touch area on which sensing electrodes are disposed. The light-emitting elements are respectively accommodated in the through holes. After entering the light guide plate through inner walls of the through holes, the lights emitted by the light-emitting elements are guided upward through the light guide units to pass through the substrate and exit.
