Claim 0:
1. A luminous touch pad module, comprising:
a touch member;
a touch sensing circuit board located under the touch member;
a first light guide plate arranged between the touch member and the touch sensing circuit board;
a second light guide plate arranged between the touch member and the first light guide plate;
at least one first light-emitting element located over the touch sensing circuit board, wherein the at least one first light-emitting element is aligned with the first light guide plate;
a first light-guiding element arranged around the touch sensing circuit board, the first light guide plate, the second light guide plate and the at least one first light-emitting element; and
at least one second light-emitting element located under the touch sensing circuit board, wherein the at least one second light-emitting element is aligned with the first light-guiding element,
wherein a light beam emitted by the at least one first light-emitting element is transmitted to the touch member through the first light guide plate, and a light beam emitted by the at least one second light-emitting element is transmitted to the touch member through the first light-guiding element and the second light guide plate sequentially.
