Abstract
A background module includes a light-emitting element, a light guide plate, and a light shielding structure. The light guide plate includes a reflective material layer. The reflective material layer is disposed on a top surface of the light guide plate and located near the light-emitting element. After a light beam emitted by the light-emitting element is introduced into the light shielding structure, a portion of the light beam is reflected back into the light shielding structure by the reflective material layer. On the other hand, a portion of the light beam is transmitted through the reflective material layer and absorbed by the light shielding structure. Consequently, the possibility of causing light leakage will be minimized.
