Disclosed are method of providing clock function and number device thereof which belonging to mobile communication terminal parts, the method and the device provide a clock function in temporal information processing technique. The device of the invention includes: a memorizer storing the temporal processing information about the clock function; a control component executing a clock function based on the temporal processing information; a display component illuminating the dividing region relative to the gernerated display signal. In order to display the temporal processing information calculated by the clock function, the deviding region and/or illuminating color is controlled according to the temporal processing information. The user discriminates the deviding region and/or illuminating color, therefor visually affirming the time and/or date through the LED without the display of character or number. |
