摘要

A display with function of dark shining and currency identifier is provided. The display comprises a micro controller, a button unit and an ultraviolet emitter. The button unit contains an ultraviolet button, and the button unit might output an ultraviolet signal (S_UV) to the micro controller if the ultraviolet button is pressed. The ultraviolet emitter connects to the micro controller, and the micro controller may receive the ultraviolet signal (S_UV) so as to drive the ultraviolet emitter to emit ultraviolet light. Whereby, the display may achieve function of dark shining and currency identifying by means of the ultraviolet light.
