Abstract

The invention discloses a mobile communication terminal having security text output function and a text output method thereof, and the mobile communication terminal belongs to a mobile communication technology. The mobile communication terminal of the invention includes the following sections: a key input unit for outputting a key-press signal; a control unit for outputting other key value different to the pressed key in a display unit when a security function is set. The text output method outputs other key value different to the input key in the display unit when the security function is set, so as to enable other person not to distinguish the inputted content. When an user don't expect the own inputted information leaked to others, other key value different to the input key in the display unit can be inputted by setting a security function, thereby other persons can't distinguish the inputted information.

Description

technical field [0001] The present invention relates to a text output technology of a mobile communication terminal. More specifically, it relates to a method of outputting other key values ​​different from the input key value in the display part by setting a privacy protection function when the user does not want his input information to be disclosed to others. The key value is a mobile communication terminal with a text output function for protecting privacy and a text output method thereof, which prevent others from identifying input information. Background technique [0002] FIG. 1 is a diagram showing the configuration of a conventional key input unit. [0003] As shown in Figure 1, the input signal line IS of the printed circuit board, which is used to receive the input signal from the modem of the mobile communication terminal, the CPU of the computer, etc., and the output signal line OS arranged in parallel to output the key output signal are arranged in matrix. The...
