MOBILE TERMINAL TRANSMITTING DATA USING BY CONTROLLING SCREEN AND METHOD FOR TRANSMITTING DATA USING BY CONTROLLING SCREEN OF THE MOBILE TERMINAL

摘要

A mobile terminal for transmitting data by using a screen control and a method of transmitting data by using a screen control of the mobile terminal are provided. The mobile terminal reads out payment information stored in a memory according to a payment request from a user, converts the read-out payment information into a binary code, sequentially reads out bit values of the binary code, sequentially outputs a predetermined image data to a display unit according to the sequentially read-out bit values, outputs first image data corresponding to darkest brightness to all the cells of the display unit if the bit value constituting the binary code is 0, and outputs second image data corresponding to brightest brightness to all constituting the binary code is 1, thereby transmitting data containing the payment information as an optical signal outwardly. the cells of the display unit if the bit value
