Abstract: A light source module includes a transparent substrate, a conductive coating film structure and plural light-emitting elements. The conductive coating film structure is installed on the transparent substrate. The conductive coating film structure includes a metal conductive plate and a metal coating film. The metal conductive plate is disposed on the transparent substrate and covered by the metal coating film. The plural light-emitting elements are installed on the conductive coating film structure, and electrically connected with the metal conductive plate. The light-emitting elements are permitted to emit light beams. When the light beams are not emitted by the light-emitting elements, the light-emitting elements are not displayed on the conductive coating film structure according to a mirror reflection effect provided by the metal coating film.

Abstract: A luminous fan includes a supporting mechanism, a main circuit board, a light-guiding impeller and an illumination module. The light-guiding impeller is pivotally coupled to a bracket of the supporting mechanism. The illumination module is disposed within a hub of the light-guiding impeller. After a light beam from a light-emitting element of the illumination module is emitted to a lens assembly, the light beam is refracted by a secondary lens of the lens assembly and transmitted to the light-guiding impeller. Consequently, the light-guiding impeller is illuminated.

Abstract: An optical switch keyboard includes a circuit board and plural keys. The circuit board includes plural light emitters and plural light receivers. Each key is aligned with the corresponding light emitter and the corresponding light receiver. Moreover, each key includes a triggering element, a first reflective element and a second reflective element. When the triggering element is triggered by the user, a sensing light emitted by the light emitter is reflected to the second reflective element by the first reflective element. The sensing light is further reflected to the light receiver by the second reflective element. Consequently, the circuit board generates a key switch signal.

Abstract: A touch module includes a touch sensor panel, a light guide plate, an adhesive layer and a shielding body. The touch sensor panel includes an opening. The adhesive layer includes a groove part. The light guide plate is located over the touch sensor panel. The adhesive layer is arranged between the touch sensor panel and the light guide plate. The touch sensor panel and the light guide plate are attached on each other through the adhesive layer. The groove part of the adhesive layer is in communication with the opening of the touch sensor panel to exhaust the gas. The shielding body surrounds the edge part of the light guide plate and the outer periphery part of the touch senor panel. Due to the shielding body, the light beam transferred in the light guide plate will not be leaked out.

Abstract: A light guide structure for a backlight module is provided. A light source of the backlight module emits a light beam. The light beam is guided by the light guide structure. The light guide structure includes a plate body and a light-shielding layer. The plate body includes a light-transmissible plate, a light-guiding plate and a reflecting plate. The light-guiding plate has a lateral surface. The light-transmissible plate has a light-transmissible plate lateral surface. The reflecting plate has a reflecting plate lateral surface. The lateral surface of the light-guiding plate, the light-transmissible plate lateral surface and the reflecting plate lateral surface are collaboratively formed as a plate body lateral surface. The plate body lateral surface is covered by the light-shielding layer. The light beam from the light source is blocked by the light-shielding layer.

Abstract: A display device is disposed within a casing of an electronic device. The display device includes a display part, at least one light source, a projection part and an imaging structure. The display part is disposed on the casing and exposed outside. The at least one light source is disposed within the casing, and emits at least one light beam. The projection part is arranged between the at least one light source and the display part, and has an image region. After the at least one light beam passes through the projection part, a projection pattern corresponding to the image region is generated. The imaging structure is disposed on the display part. The imaging structure receives the projection pattern, so that the projection pattern is shown on the display part.
