Abstract: An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The light-emitting die package is disposed to illuminate the keycap through the base plate. The light-emitting die package comprises a warm color temperature light-emitting die and a cold color temperature light-emitting die, and the light-emitting die package extends along an arrangement direction. Each of the two light-emitting dies has a short side arranged adjacent to each other, with a long side of each of the two light-emitting dies facing a same direction and configured proximate to each other. A gap between the two adjacent short sides of the two light-emitting dies is not greater than either one of the two adjacent short sides of the two light-emitting dies.

Abstract: A keyswitch backlight structure includes a light-guiding layer, a reflective layer, and a transparent adhesive layer. The light-guiding layer has a bottom surface, a light-emitting surface opposite to the bottom surface, and a surface microstructure formed on the light-emitting surface. The reflective layer is disposed opposite to the bottom surface. The transparent adhesive layer is closely attached to and between the reflective layer and the light-guiding layer corresponding to the surface microstructure. An illuminated keyswitch structure includes base plate, a keycap, a supporting mechanism, and the above keyswitch backlight structure. The keyswitch backlight structure and the base plate are stacked. The supporting mechanism is connected to and between the base plate and the keycap for lifting the keycap relative to the base plate. Light entering the light-guiding layer exits the light-guiding layer through the light-emitting surface to illuminate a transparent indication area of the keycap.

Abstract: An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting die package is disposed under the keycap and includes a plurality of light-emitting dies. The plurality of light-emitting dies are monochromatic light-emitting dies. Therein, among the plurality of light-emitting dies, three light-emitting dies that are adjacently arranged in an arrangement direction perpendicular to the vertical direction emit light of three different colors. The arrangement direction is respectively parallel to along side of each of the three adjacent light-emitting dies.

Abstract: A luminous keyboard includes a keyswitch module and an optical module disposed under the keyswitch module. The keyswitch module includes a plurality of keyswitches. The optical module includes a mask film and a light guide sheet. The mask film has a mask pattern. The mask pattern defines a plurality of light-transparent regions respectively corresponding to the plurality of keyswitches, and an outer light-transparent region of the plurality of light-transparent regions has a boundary. The light guide sheet has a light-exit edge. The vertical projection of the light-exit edge of the light guide sheet on the mask film at least partially falls within the outer light-transparent region and is not parallel to the boundary.

Abstract: An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting die package is disposed under the keycap and includes a plurality of light-emitting dies generating light of at least three colors. The plurality of light-emitting dies are distributed in a plane and are monochromatic light-emitting dies. Therein, among the plurality of light-emitting dies, adjacent two light-emitting dies that are arranged in a first arrangement direction perpendicular to the vertical direction emit light of different colors. Among the plurality of light-emitting dies, adjacent two light-emitting dies that are arranged in a second arrangement direction perpendicular to the vertical direction emit light of different colors. The first arrangement direction and the second arrangement direction are non-parallel.
