1. An illuminated keyswitch structure, comprising:
a base plate;
a keycap, movably disposed above the base plate in a vertical direction; and
a light-emitting die package, disposed under the keycap and comprising a plurality of light-emitting dies, the plurality of light-emitting dies being monochromatic light-emitting dies, wherein among the plurality of light-emitting dies, three light-emitting dies that are adjacently arranged in a first arrangement direction perpendicular to the vertical direction emit light of three different colors, and the first arrangement direction is respectively parallel to a long side of each of the three adjacent light-emitting dies;
wherein the plurality of light-emitting dies are arranged in a rectangular ring, and any two adjacent light-emitting dies along the rectangular ring emit light of different colors.
