摘要： A keyboard device includes at least an illuminant element, at least a pressing key element and a light guide element. The pressing key element includes a keycap reciprocating along a first axial direction when being pressed and a recovering component attached to the keycap for supporting and pushing back the keycap when not pressed. The light guide element is located at one side of the recovering component. The light guide element includes at least a light-incident part and a light-emitting part. The light-incident part is used for receiving light emitted from the illuminant element. The light-emitting part emits light along a second axial direction to the recovering component so that the recovering components guide light to the keycap, wherein the second axial direction is different to the first axial direction.

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 backlight module includes a light guide plate and a lighting source. The light guide plate has a main body with a light incidence surface and a light emitting surface. A plurality of accommodating grooves are provided on the light incidence surface, and a plurality of light-separation grooves which are perpendicular to the accommodating grooves are provided on the light emitting surface. The light source includes a circuit board and a plurality rows of light bars welded on the circuit board, where each light bar is composed of a plurality of light emitting diode. When the light source is assembled to the main body, the circuit board is attached to the light incidence surface such that the light bars are disposed for the corresponding accommodating grooves. Therefore, the light-separation grooves can effectively optically separate the light when the light bars are illuminated.
