Abstract
A luminous touch pad module includes a touch member, a touch sensing circuit board, a first light guide plate, a second light guide plate, a first light-emitting element, a first light-guiding element and a second light-emitting element. The touch member, the second light guide plate, the first light guide plate and the touch sensing circuit board are sequentially arranged from top to bottom. The first light-emitting element is aligned with the first light guide plate. The second light-emitting element is located under the touch sensing circuit board. The second light-emitting element is aligned with the first light-guiding element. A light beam emitted by the first light-emitting element is transmitted to the touch member through the first light guide plate. A light beam emitted by the second light-emitting element is transmitted to the touch member through the first light-guiding element and the second light guide plate sequentially.
