Abstract

The invention discloses an illuminated keyswitch structure, which includes a base plate, a keycap, and a plurality of light-emitting dies. The base plate has a through hole. The keycap is movably disposed above the base plate in a vertical direction. The light-emitting dies are disposed under the keycap. The light-emitting dies are not higher than the base plate. The light-emitting dies are located within a projection of the through hole in the vertical direction. At least two of the light-emitting dies are arranged parallel to an hole edge of the through hole. In the illuminated keyswitch structure of the invention, distances from the light-emitting dies that are arranged parallel to the hole edge to the hole edge are close to each other, and light of different colors emitted by said light-emitting dies travels through the hole edge at similar distances, thereby suppressing uneven light mixing and color deviation.
