ABSTRACT:
A method of and an apparatus for displaying temperature on a radio telephone. The temperature apparatus includes a key pad for producing a temperature mode or a speech mode, a device for measuring current room or environment temperature, analog/digital converting device for converting current room or environment temperature into a digital value, and a microcomputer for storing the digital temperature value in a memory of the radio telephone. The method includes the steps of a) using key for determining whether a temperature mode is selected, b) reading current environment temperature through the temperature measuring device, and displaying the measured current temperature on a liquid crystal display for a predetermined time, c) stopping the temperature mode, and converting the temperature mode into a speech mode. The liquid crystal display and driving device for driving the liquid crystal display of the radio telephone is utilized for optionally displaying temperature or telephone numbers of transmitters and receivers, which is more cost effective. In addition, the temperature display apparatus of the present invention may be applied to a variety of microcomputer-bases systems, for example, computers or copying machines.
