摘要： A lighting keyboard includes a backlight module and two rows of keyswitches. The backlight module includes a lighting board and a shielding sheet. The lighting board includes plural illuminants aligned into two rows to correspond to the two rows of keyswitches. The shielding sheet includes plural first outlet windows and plural first block patterns disposed within the first outlet windows respectively and form a first row pattern collectively. Each of the first block patterns respectively corresponds to one of the illuminant. The shielding sheet includes at least one second outlet window and plural second block patterns respectively disposed within the at least one second outlet window and formed a second row pattern collectively. Each of the plural second block patterns respectively correspond to one of the plural illuminants. A first window length of the entire contour of the plural first outlet windows is as long as a second window length of the at least one second outlet window. And the first row pattern is not identical to the second row pattern, thereby providing consistent contour halos for the two rows of keyswitches.

摘要： A backlight module includes a lighting board, a light guide panel, a shielding sheet, and a protrusion structure. The lighting board includes two non-intersected traces, a plurality of microstructure regions and at least one illuminant unit. The illuminant unit is connected between the microstructure regions. The microstructure regions do not overlap with the two non-intersected traces. The light guide panel is disposed above the lighting board, and the shielding sheet is disposed above the light guide panel. The protrusion structure is formed on the shielding sheet, protrudes towards the lighting board, and is between the microstructure regions. The protrusion structure diffuses light of the illuminant unit at an early section of its light path to enter into the light guide panel for lateral transmission. The plural microstructure regions reflect and recycle the light at a following section of the light path to jointly enhance the uniformity of illuminating a keycap.

摘要： A backlight module applicable to a key module is provided, the key module includes a plurality of key units and a baseplate, and the plurality of key units are disposed on the baseplate. The backlight module includes a lower substrate, a plurality of periphery light sources disposed along the peripheral of the baseplate, and a shielding structure. The lower substrate is disposed below the baseplate, and there is an outer edge gap between an outer edge of the baseplate and the lower substrate. The periphery light sources are disposed between the baseplate and the lower substrate. The shielding structure is disposed outside those periphery light sources distributed, to prevent light provided by the plurality of light sources from being emitted out of the outer edge gap.

摘要： A backlit keyboard includes a keyboard module having a plurality of key units and a light guide module including a light guide plate, a metal layer, and an insulation layer. The light guide plate has a light-exit surface and a bottom surface. The metal layer has an upper surface and a lower surface, wherein the upper surface is attached to the bottom surface of the light guide plate. When light is incident onto the upper surface of the metal layer, the light will be reflected back into the light guide plate. When electromagnetic wave reaches the lower surface of the metal layer, the metal layer will shield the electromagnetic wave from propagating. The insulation layer substantially covers the lower surface of the metal layer, wherein at least one ground window is formed in the insulation layer to expose the metal layer.

摘要： A light emission module and a light guide plate and a manufacturing method thereof are provided. The light guide plate is configured to guide the light received and has a first lateral surface and a tongue extending from the first lateral surface toward a light source. The tongue has a flat end surface that faces or engages with the light source. The light guide plate receives the light emitted from the light source by the flat end surface, so as to reduce or eliminate the gap between the light source and the light guide plate. Therefore, the loss of light energy during the light traveling in air is effectively reduced, and the intensity of light received by the light guide plate from the light source meets expectation, improving the lighting effect of the light emission module.
