Abstract: A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, a membrane switch circuit module, and a light guide plate. The light guide plate is thicker than the light guide plate. The supporting plate has an opening corresponding to the light-emitting element. The light-emitting element is inserted into the opening. The light-emitting element is used for emitting plural light beams. A portion of the plural light beams are traveled along the path under the supporting plate and introduced into the light guide plate. Consequently, the portion of the plural light beams will be directed to the plural keys to illuminate the plural keys. Another portion of the plural light beams are traveled along the path over the supporting plate and introduced into the membrane switch circuit module. Consequently, the luminous efficiency of the slim-type luminous keyboard device is enhanced.

Abstract: A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, and a light guide plate. The supporting plate has a supporting plate opening, and the supporting plate opening has a light-guiding slant surface. The light-emitting element is inserted into the supporting plate opening for emitting plural light beams. When the plural light beams are emitted by the light-emitting element, the plural light beams are guided by the light-guiding slant surface to be introduced into the light guide plate, and the plural light beams are directed to the plural keys to illuminate the plural keys. Consequently, the light amount of the light beams to be introduced into the light guide plate will be increased.

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.

Abstract: A luminous keyboard device includes a keypad module, a supporting plate, a light-mixing type light-emitting element, a first light guide plate, and a second light guide plate. The supporting plate has a partition part. By the partition part, a first color light beam and a second color light beam from the light-mixing type light-emitting element are not mixed with each other. The first color light beam is guided by the first light guide plate to a first light-outputting zone and a third light-outputting zone of the keypad module. The second color light beam is guided by the second light guide plate to a second light-outputting zone and the third light-outputting zone of the keypad module. The first color light beam and the second color light beam projected on the third light-outputting zone are mixed as a third color light beam.

Abstract: A luminous keyboard device includes plural keys, a light-emitting element, and a light guide plate. By the light guide plate, a light beam emitted by the light-emitting element is guided to the plural keys. The light guide plate includes plural elongated slots and a light-absorbing part. The plural elongated slots are located near a lateral edge of the light guide plate. After the light beam transferred within the light guide plate is transmitted through the elongated slots and departed from the light guide plate, the fraction of the light beam introduced into the lateral edge of the light guide plate is reduced. The light-absorbing part is located at the lateral edge of the light guide plate for absorbing the portion of the light beam which is introduced into the lateral edge of the light guide plate. Consequently, the lateral light leakage of the light guide plate can be avoided.

Abstract: An illuminated keyboard comprises a fixing sheet, a membrane switch circuit module, a supporting plate, a light guide plate, a sensing circuit, a sensing chip, a light-emitting element, and an illumination circuit board. The sensing circuit is formed on the fixing sheet or the membrane switch circuit module. The sensing chip and the light-emitting element are disposed on the illumination circuit board. In addition, the sensing chip is accommodated within corresponding openings of the fixing sheet, the membrane switch circuit module, the supporting plate and the light guide plate. The illuminated keyboard uses the sensing circuit and the sensing chip to sense the presence of an object. Since the illuminated keyboard does not need an additional space to accommodate the sensing circuit and the sensing chip, the illuminated keyboard can meet the requirement of slimness.
