Abstract: A character-recognition system provided in a digital mobile communication terminal, comprises a display, a touch panel for generating pressure signals in response to the pressures applied by the characters written on its surface a touch panel drive for generating coordinate data and touch panel state data from the pressure signals, a character data base for storing character data consisting of shapes and stroke data of the characters, a character-recognition for generating the addresses of the precise character data retrieved from the character data base by recognizing the data of the written characters, a character code storage for storing the character codes corresponding to the character data stored in the character data base, and a controller for delivering the stroke data of the written characters calculated from the coordinate data and touch panel state data to the character-recognition means, wherein the controller retrieves the character codes from the character code storage corresponding to the addre

Abstract: A method of storing data in an electronic phone data book for a digital mobile phone, which includes a key input part, display, touch screen for inputting characters, character code storage for storing character and number codes, character database for storing feature data corresponding to character and number codes, and character recognition device. A method of searching through the electronic phone data book includes setting the mobile phone in a search mode, generating a search mode character code corresponding to touch screen data input, determining whether the search mode character code is registered in said phone book storage and displaying a corresponding phone number if it is.

Abstract: A mobile telephone is provided which includes a touch screen, character recognition means for recognizing data inputted via the touch screen, and a processing unit for receiving at least one secret symbol inputted via the touch screen while the mobile telephone is in a password registration mode. The processing unit providing the at least one secret symbol to the character recognition means for recognizing the at least one secret symbol and generating feature data corresponding thereto. The processing unit stores the feature data in a database to register the at least one secret symbol as a password. The processing unit further compares the stored feature data with feature data corresponding to data inputted via the touch screen for determining whether the inputted data is substantially similar to the at least one secret symbol while the telephone is in a password identification mode. A method is also provided for registering a secret symbol as a password.

Abstract: A character recognition mobile telephone registers and performs various functions of the telephone using a character recognition function. The character recognition mobile telephone includes a function character storage for registering character codes corresponding to various functions of the mobile telephone; a touch screen with which a user inputs a desired function character; a character recognizer for generating feature data for the character input from the touch screen and a corresponding character code, and searching the function character storage for a character code identical to the generated character code; and a controller for entering a function mode corresponding to the input character.
