Abstract

An electronic device includes a detecting module, a signal processing module connected to the detecting module, a controlling module connected to the signal processing module and a display connected to the controlling module. The detecting module outputs a first detect signal to the signal processing module when a human body is present in front of the display. The signal processing module transforms the first detect signal into a first control signal and outputs the first control signal to the controlling module. The controlling module causes digital content to be played on the display.

Claims

1. An electronic device, comprising:

a detecting module;

a signal processing module connected to the detecting module;

a controlling module connected to the signal processing module; and

a display connected to the controlling module;

wherein the detecting module outputs a first detect signal to the signal processing module when a human body is present in front of the display, the signal processing module transforms the first detect signal into a first control signal and outputs the first control signal to the controlling module, the controlling module causes the digital content to be played on the display.

2. The electronic device of the claim 1, wherein the signal processing module further comprises a signal amplification sub-module and a signal comparison sub-module, the signal amplification sub-module is configured for amplifying the first detect signal and outputting the amplified first detect signal to the signal comparison sub-module, and the signal comparison sub-module is configured for comparing the amplified first detect signal with a standard signal.

3. The electronic device of the claim 1, wherein when the detecting module outputs a second detect signal to the signal processing module when no human body is present, the signal processing module transforms the second detect signal into a second control signal and outputs the second control signal to the controlling module, and the controlling module causes the digital content on the display to be paused on the condition that the display is playing.

4. The electronic device of the claim 3, wherein the controlling module is capable of causing the digital content to be played on the display when the first control signal is received by the controlling module and the digital content is paused.

5. The electronic device of the claim 3, wherein the controlling module is capable of powering off the display on the condition that the digital content is paused for a predetermined delay time;

and the controlling module comprises a time sub-module for setting the predetermined delay time.

6. The electronic device of the claim 3, wherein the first detect signal and the second detect signal are selected from the group consisting of a high level signal and a low level signal;

and the second detect signal is different than the first detect signal.

7. The electronic device of the claim 1, wherein the controlling module comprises a storage sub-module for storing the digital content.

8. The electronic device of the claim 1, wherein the detecting module is an infrared (IR) sensor, and the IR sensor is configured to detect the presence of the human body from a body temperature.

9. The electronic device of the claim 1, wherein the signal processing module and the controlling module are embedded system components.

10. A method for playing digital content in an electronic device, comprising:

detecting the presence of a human body in front of a display by a detecting module;

the controlling module causing the digital content to be paused on the condition that the display is playing.

13. The method of claim 12 further comprising:

the controlling module causing the digital content to be played on the display when the first control signal is received by the controlling module and the digital content is paused.

14. The method of claim 12 further comprising:

the controlling module powering off the display on the condition that the digital content is paused for a predetermined delay time.

15. The method of claim 12, wherein the first detect signal and the second detect signal are selected from the group consisting of a high level signal and a low level signal;

and the second detect signal is different than the first detect signal.

16. The method of claim 10, wherein the controlling module comprises a storage sub-module for storing the digital content.
