摘要： A key structure having an improved light emitting efficiency is provided. The key structure includes a light guide plate, an isolation sheet, a circuit board, an elastic member, and a key cap sequentially disposed one on another in order. A circuit and a plurality of first electrical contacts are distributed on a top surface of the light guide plate. An optical structure is disposed at a bottom surface of the light guide plate. The isolation sheet has a light reflective surface facing the light guide plate. A light source emits a light into the light guide plate. The light is reflected by the optical structure to pass through the through holes configured at the isolation sheet, thus allowing more light outputting through the through holes, so as to improve the illumination of the key cap, and improve the light emitting efficiency.

摘要： A structure for eliminating bright lines of a tiled backlight module is provided. The structure includes a light guide plate, and a plurality of light sources. The light guide plate includes a plurality of rows of optical elements. The rows of optical elements extend in parallel. The light sources are provided at least one side of the light guide plate for projecting a light into the light guide plate and generating a regular but non-uniform light outputting performance of the light guide plate. Therefore, a brightness of areas where the optical elements are located is higher than the rest areas, so that the light guide plate achieves a regular but non-uniform light emitting performance. Accordingly, the bright lines occurred at joints between two light guide plates are enshrouded by the high brightness areas, and become hard to identify or even undistinguishable, thus “eliminated”.

摘要： A method and a structure for improving the uniformity of light emitted from a backlight module are provided. In accordance with the present invention, a plurality of optical microstructures are intermittently distributed on an LGP of a backlight module. Each of the microstructures further includes a plurality of optical sub-microstructures. The optical microstructures and the optical sub-microstructures are distributed on the LGP with varied distribution intensities in three dimensions, such that at where the optical microstructures and the optical sub-microstructures are distributed with a larger distribution intensities the LGP refracts and reflects more light, and at where the optical microstructures and the optical sub-microstructures are distributed with a smaller distribution intensities the LGP refracts and reflects less light. In such a way, by designing particular distribution intensities of the optical microstructures and the optical sub-microstructures, the light emitted from the LGP can be uniformed.

摘要： A light emitting key structure is provided. The key structure includes a base, a reflective sheet, a circuit board, an elastic member, a linkage mechanism, and a key cap sequentially disposed one on another in order. The reflective sheet is disposed on the base. The circuit board is made of a light guide material. At least one light source is bonded to a lateral side of the circuit board. The circuit board, together with the light source bonded to the lateral side thereof is disposed on the reflective sheet. The elastic member is directly coupled to the circuit board. The key cap is featured with a light transmission characteristic. Therefore, in operation, the light emitted from the light source can be directly guided into the circuit board, and then outputted from the light transmissive key cap, thus achieving the light emitting effect.
