APPARATUS AND METHOD FOR CALIBRATIONING TOUCH SCREEN IN POTABLE TERMINAL

摘要

A touch screen compensation method and an apparatus thereof in a portable terminal for inputting data for compensating the input coordinates by using a small icon which is expressed on a touch screen in a portable terminal are provided to enhance the accuracy of the touch screen. If there is the input of a user at a specific icon corresponding to a correction point, a coordinate toward the input of user is stored through the application on a touch screen(201-205). If the stored coordinate is accumulated for the input coordinate correction of the touch screen, the stored input coordinate is compared with the input coordinate(207). If error is calculated through the compared value and is greater than the calibration value, auto-calibration is performed through the stored input coordinate on the domain of the specific icon corresponding to the major correction point(211-215).
