Apparatus and method for providing a visual indication of receipt of an electronic message by changing the color of at least a portion of a display formed of liquid crystal according to the message received. A first circuit receives an incoming signal, a second circuit identifies the incoming signal by comparing the incoming signal with stored signals, and a third circuit causes a predetermined voltage to be coupled to a predetermined area of the liquid crystal to cause the predetermined area to assume a predetermined color to call attention to the incoming message.
