ABSTRACT:
An apparatus and a method for providing improved character input displays in a mobile communication terminal. When the user inputs a first key, a first key number corresponding to the input key is displayed in an enlarged form on the display unit in the mobile communication terminal. Thereafter, if the user inputs a second key, then the second key number is displayed in the enlarged form of the preset magnification rate and the first key number is reduced to the original size on the display unit. The apparatus and the method enable user with poor vision to discern the last input key number from the preceding key numbers.
