Abstract: PURPOSE: A method for displaying a clock in a portable radio terminal is provided so that a back light is turned on to display the clock by pressing an external key. CONSTITUTION: A microprocessor confirms whether an external key of a portable radio terminal, for example an up or down key is pressed(201). The microprocessor detects whether the up or down key is pressed over a predetermined time. When the up or down key is not pressed over a predetermined time, the microprocessor performs a function corresponding to the pressed key(208). When the external key is pressed over a predetermined time, the microprocessor turns on an LCD back light of a display unit(203). While the up or down key is being pressed, the microprocessor displays a current time by numbers or in an analog clock type. Here, the user should press the up or down key until he/she can confirm the current time. Thereafter, the microprocessor confirms whether the up or down key is not processed(205). When the up or down key is pressed, the microprocessor returns to the step 204. When the up or down key is not pressed, the microprocessor goes to the step 206. That is, the microprocessor turns off the LCD back light of the display unit(206), and then displays standby mode display information(207).
