Abstract: A membrane circuit board includes a first flexible circuit board, a second flexible circuit board and a nanomaterial layer. The nanomaterial layer includes plural polymeric structures. The nanomaterial layer is formed on the first flexible circuit board, the second flexible circuit board and/or a junction region between the edge of the first flexible circuit board and the second flexible circuit board to prevent at least one of the upper metallic conductor line and the lower metallic conductor line from contacting with a specified chemical element. Consequently, the conductive impedance of the upper metallic conductor line and the lower metallic conductor line is not affected by the specified chemical element. Moreover, the present invention also provides a keyboard device with the membrane circuit board.

Abstract: A keyboard device includes plural key structures, a switch circuit board, an elastic cover and a seal element. The switch circuit board includes a hollow region. The elastic cover is disposed on the switch circuit board. The hollow region is covered by the elastic cover, so that a foreign liquid is prevented from entering the switch circuit board. The seal element is disposed on sidewalls of the switch circuit board. Consequently, a sealed region is formed between the switch circuit board and the elastic cover. When the inner gas within the switch circuit board is changed, the elastic cover is subjected to expansion or contraction. Consequently, the switch circuit board is not subjected to deformation in response to the volume change of the inner gas.

Abstract: A key structure includes a switch circuit board, a triggering assembly, a keycap and an elastic element. The triggering assembly is disposed over the switch circuit board. The elastic element is arranged between the keycap and the triggering assembly. As the keycap is moved, the triggering assembly is pushed by the elastic element. The elastic element includes a concave part. The concave part is located at a top end of the elastic element and contacted with the keycap. When the elastic element is pushed by the keycap, the concave part is subjected to deformation, so that a movable distance of the keycap toward the switch circuit board is increased. By using the key structure, the tactile feel of depressing the keycap is enhanced.

Abstract: A keyboard device includes a key structure, a base plate and a switch circuit board. The switch circuit board includes a soft covering element. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft covering element. The soft covering element is disposed on the switch circuit board. An accommodation space is formed between the soft covering element and the switch circuit board. The stabilizer bar is inserted into the accommodation space and connected with the switch circuit board. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the switch circuit board, the keyboard device is capable of reducing noise.

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.
