A planar light source device (6) for a liquid crystal display device. The planar light source device includes a light source device (2) and a light guide plate (67). The light source device includes a light-emitting element (21), and an optical guiding member (20) that is hollow and has a reflective surface. The reflective surface receives light rays emitted by the light-emitting element, and guides the light rays out from a plurality of generally aligned through holes (23) defined in a front light-emitting surface (28) of the optical guiding member.

An illuminated logo unit (300) includes a reflective board (320), a pattern panel (301), an illuminating device (310), and a reflective film (305). The pattern panel is arranged over the reflective board, and the reflective film is disposed under the pattern panel opposite to the reflective board. Much light emanating from the illuminating device is reflected more than once by the reflective film and the reflective board before it reaches the pattern panel. This enhances the overall brightness and uniformity of light beams of the illuminated logo unit. Even at night, the illuminated logo unit can be clearly viewed. The illuminated logo unit may be used for applications such as in a billboard, a logo displayed on a vehicle, and so on.

An image sensor package (10) includes a housing (34) defining a top opening, an image sensor (14) received in the housing, and a converging lens (36) covering the opening to hermetically seal the housing and form a window for light to pass through into the housing. The image sensor has an active area which faces the converging lens and which is responsive to light. The converging lens not only provides hermetic sealing for the housing, but also converges light before the light strikes the active area of the image sensor. Accordingly, a focal length F is reduced, and a size of the image sensor package and the image sensor system can be reduced.

A portable communication device includes a body (11) having a container (111) and a buffer room (115), and a plurality of fragrance releasing apparatuses (12) housed in the container. The body houses main circuitry therein. The buffer room communicates with the container and outside environment. The container also houses a plurality of electrical connectors therein. The electrical connectors are electrically connected with the main circuitry. Each fragrance releasing apparatus includes a vessel (121) with a nozzle (127). Each nozzle includes a heater (128) connecting with and being enabled by the main circuitry via the corresponding electrical connector. When the portable communication device receives an incoming call (or message), predetermined heaters are enabled by the main circuitry to release a fragrance corresponding to the caller (or sender).

A display apparatus (20) includes a display panel (22) having pixels, a movable light shielding plate (23), and a light deflection plate (24). The light shielding plate is interposed between the display panel and the light deflection plate, and includes strip-shaped transparent portions (231) and strip-shaped non-transparent portions (232) alternately arranged thereat. The light deflection plate includes a transparent substrate (243) having light deflection elements (2411) formed thereon. The light deflection elements are arranged in rows, which are spaced apart at predetermined intervals. The light deflection elements respectively correspond to individual pixels of the display panel. When the light shielding plate is positioned so that the transparent portions correspond to the light deflection elements, the light deflection elements operate to provide 3D images. When the light shielding plate is positioned so that the non-transparent portions correspond to the light deflection elements, the light deflection plate operates to provide 2D images.

A light aperture apparatus (1) used with an auto imaging machine comprises an aperture mask (30), a transparent structure (20), and an circuit chip (10), wherein the aperture mask is constructed of an opaque material and has a plurality of holes formed therein. The further the hole is from a center of the aperture mask, the larger the diameter of the hole is. The transparent structure has a plurality of lenslets (26) on it. Each lenslet corresponds in position to a hole of the aperture mask. The circuit chip has a plurality of detector areas (14) surrounded by non-detector areas (15). Each detector area corresponds in position to a lenslet on the transparent structure.

A fiber display device (200) includes a light source (21), a fiber binding (27) for transmitting light beams from the light source and a brightness modulating system (29) for modulating the transmission of the light beams. The fiber binding includes a plurality of fibers (272), one terminal end of the fibers acting as a light incidence terminal for receiving light beams from the light source, the other terminal end of the fibers acting as a display terminal. The brightness modulating system is disposed between the light incidence terminal and the display terminal. This simplifies the structure and reduces the cost of the fiber display device.
