ELECTRONIC DEVICE AND DISPLAY CONTROL METHOD THEREOF
First Claim
1. An electronic device, comprising:
- a display unit for displaying desired information;
a detecting unit for detecting nearby persons and generating a signal when at least one unauthorized person is detected within a predetermined distance of the electronic device;
a timing unit for receiving the signal and timing duration during which the signal is continuously generated;
a judging unit for judging whether the timed duration reaches a predetermined time period and generating a distance calculating signal if the timed duration reaches the time period;
a distance calculating unit for calculating the distance between the at least one unauthorized person and the electronic device in response to the distance calculating signal; and
a controller for adjusting display parameters of the display unit according to the distance between the at least one unauthorized person and the electronic device to prevent the at least one unauthorized person from viewing the desired information.

Abstract
An electronic device includes a display unit, a detecting unit, a timing unit, a judging unit, a distance calculating unit, and a controller. The display unit displays desired information. The detecting unit detects nearby persons and generates a signal when at least one unauthorized person is detected within a predetermined distance of the electronic device. The timing unit receives the detecting signal and times duration during which the detecting signal is continuously generated. The judging unit judges whether the timed duration reaches a predetermined time period and generating a distance calculating signal if the timed duration reaches the time period. The distance calculating unit calculates the distance between the at least one unauthorized person and the electronic device in response to the distance calculating signal. The controller adjusts the display parameters of the display unit according to the calculated distance.
