Abstract
A backlight button assemblage includes an opaque button, a light-guiding element, and a light-emitting element. The light-emitting element is disposed under the button and light emitted from the light-emitting element is guided to the front side of the button via the light-guiding element surrounding the button. Light can therefore be evenly distributed over the light-guiding element, and uniformity of light achieved, so that partial dazzling spots are avoided, the quantity of light-emitting elements is reduced, and fabrication costs are saved.
