Abstract
A luminescent keyboard includes a light-guide board, a thin-film circuit board, a key module and at least one light-emitting component. The thin-film circuit board is disposed on the light-guide board. The key module is disposed on the thin-film circuit board. The light-emitting component is disposed at a position corresponding to one side of the light-guide board. The light-guide board includes a body and a plurality of light-guiding structures. The light-guiding structures are disposed on the body and respectively located at positions corresponding to the keys of the key module. The light-emitting component emits light toward the light-guide board, such that the light diffuses in the body and the light-guide structures and is guided to the keys by the light-guide structures, so as to enhance the brightness and uniform illumination of the luminescent keyboard and lowers the cost of the luminescent keyboard.
