Abstract: A luminous keyboard includes a lateral-emitting type illumination element, a light guide panel, a sensing circuit pattern, a light-transmissible supporting plate, and plural keys. The lateral-emitting type illumination element is used for providing a light beam to the light guide panel. Consequently, the light beam can be diffused to the whole light guide panel. The light guide panel has plural light-guiding dots for collecting and scattering the light beam. The light-transmissible supporting plate is arranged between the light guide panel and the plural keys, and has plural light diffusion structures corresponding to the plural keys. The light beam scattered upwardly by each light-guiding dot is sequentially transmitted through the corresponding light diffusion structure and directed to the corresponding key. When one of the keys is moved toward the sensing circuit pattern, the sensing circuit pattern generates a corresponding non-contact key signal.

Abstract: An illuminated keyboard includes a key, a light guide plate, a sensing circuit layer, and a light-transmissible elastic element. The light-transmissible elastic element is disposed under the key. The light-transmissible elastic element has a light-diffusing part. The light guide plate and the sensing circuit layer are disposed under the light-transmissible elastic element. The sensing circuit layer is used for generating a non-contact key signal. After the light beam transferred within the light guide plate is transmitted upwardly through the light guide plate, the light beam is transmitted through the light-transmissible elastic element. Moreover, since the optical path of the light beam is changed by the light-diffusing part, the light beam can be projected onto the whole keycap more uniformly.

Abstract: An illuminated keyboard includes a light source, a key structure, and a backlight membrane switch module. The backlight membrane switch module is disposed under the key structure for generating a key signal and transferring a light beam from the light source to the key structure. The backlight membrane switch module includes a light guide plate and a membrane switch circuit board. The membrane switch circuit board is disposed over the light guide plate. Moreover, the membrane switch circuit board includes a wiring plate, a partition plate, and a light-shading part. The light-shading part is located at a side of the wiring plate or the partition plate, and bent downwardly to a position under the light guide plate in order to enclose a lateral surface of the light guide plate. Consequently, the problem of causing light leakage will be eliminated.

Abstract: A luminous keyboard includes plural bottom-emitting type illumination elements, a sensing module, plural keys, and plural light-transmissible elastic elements. As a key is moved toward the sensing module, the sensing module generates a corresponding non-contact key signal. Each bottom-emitting type illumination element is aligned with a key, and disposed under the corresponding key. Each light-transmissible elastic element is aligned with a bottom-emitting type illumination element, and arranged between the corresponding bottom-emitting type illumination element and the corresponding key. After the light beam provided by each bottom-emitting type illumination element is transmitted through the corresponding light-transmissible elastic element, the light beam is projected to the corresponding key.

Abstract: An illuminated keyboard includes a key structure, a non-contact sensor board, a light source, a light guide plate, and a light source circuit layer. The non-contact sensor board is used for sensing the key structure. The light source circuit layer is disposed on the non-contact sensor board for driving the light source to emit a light beam. The light guide plate is located at a side of the light source for transferring the light beam from the light source. Since the light source circuit layer is disposed on the non-contact sensor board, the overall height of the illuminated keyboard is reduced. Moreover, since the light source circuit layer is disposed on the non-contact sensor board, the non-contact sensor board and the light source circuit layer have a shared pin. Under this circumstance, the ease of assembling the illuminated keyboard of the present invention is enhanced.

Abstract: A touch display device includes a display panel and a light guide board. The light guide board includes a light guide base, a touch-sensitive membrane, and a buffer layer. The touch-sensitive membrane is disposed on a first surface of the light guide base for sensing the positions of the user's fingers or other indicants. The buffer layer is arranged between the light guide base and the touch-sensitive membrane for separating said light guide base from the touch-sensitive membrane. Since the touch-sensitive membrane is disposed on the light guide base, it is not necessary to provide an additional plastic substrate to install the touch-sensitive membrane thereon. Consequently, the thickness of the touch display device can be reduced.
