Abstract: A touchpad module includes a bracket, a touch member and a supporting plate. The supporting plate is arranged between the bracket and the touch member. When an end of the touch member is pressed down, the end of the touch member is swung relative to the bracket through the supporting plate. The supporting plate includes a plate body, at least one supporting part and a swingable part. The plate body, the at least one supporting part and the swingable part are integrally formed as a one-piece structure. The present invention further provides a computing device with the touchpad module.

Abstract: A light source module includes a transparent conductive substrate and plural light source groups. The transparent conductive substrate includes a substrate base, plural positive electrodes, plural negative electrodes and plural gaps. The plural positive electrodes and the plural negative electrodes are installed on the substrate base. Each light source group includes plural light-emitting elements. The plural positive electrodes are separately arranged. Consequently, the resistances of the light-emitting elements are substantially equal.

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.

Abstract: A luminous fan includes a fan frame, a main circuit board, a light guide element and a light-guiding impeller. The main circuit board is disposed on a bracket of the fan frame and includes a first light-emitting element. The light guide element is located over the main circuit board, and includes a light input surface and light output surface. A light guide post is disposed on the light input surface. A reflective structure is formed on the light output surface. The light-guiding impeller is pivotally coupled to the bracket. The first light-emitting element emits a first light beam. After the first light beam is transmitted to the reflective structure through the light guide post, the first light beam is reflected by the at least one reflective structure and diffused toward a middle region of the light guide element.

Abstract: A luminous fan includes a fan frame, a base portion, an illumination module and a light-guiding impeller. The light-guiding impeller is pivotally coupled to the base portion. The illumination module is disposed within a hub of the light-guiding impeller. The illumination module emits a light beam in a direction toward blades of the light-guiding impeller. Moreover, the light beam is projected to the lateral part of the hub.

Abstract: A computing device and an input device are provided. Each of the computing device and the input device includes a control unit, a light source, a projection plate and a casing. The control unit, the light source and the projection plate are accommodated within the casing. The light source emits light beams. The projection plate includes a pattern. After the light beams pass through the projection plate, the light beams are projected outside the casing and an image corresponding to the pattern of the projection plate is formed on a projection surface that is located outside the casing. Since the projection plate is cheap and small, the fabricating cost of the computing device or the input device is reduced and the purpose of developing the computing device or the input device toward light weightiness, slimness and small size is achievable.
