A display with illuminator lamp includes a case, a display control circuit, a control unit, a display unit, and an illuminator lamp. The display is electrically connected to a personal computer; and the illuminator lamp includes three R, G, B LED lamps, an adjusting resistance, and a controlled switch assembly. The controlled switch assembly is used to receive control signals from the control unit, and control the on/off state of the illuminator lamp. The controlled switch assembly may be a switching transistor or a MOSFET. The illuminator lamp further includes three limiting resistances separately connected to the RGB LED lamps in series. With these arrangements, the display with illuminator lamp functions to illuminate a specific area before the display, so that a user may operate a keyboard or read documents in a dark environment.
