Abstract

A display system is provided. The display system includes a display unit for displaying an image, a support stand for supporting the display unit, a power source unit for supplying power to the display unit, an approaching detection unit that is formed on the support stand to detect an approach of an object, and a control unit for controlling the power source unit by recognizing a predetermined command corresponding to a detection signal from the approaching detection unit.

Claims

1. A display system comprising:

a display unit for displaying an image;

a support stand for supporting the display unit;

a power source unit for supplying power to the display unit;

an approaching detection unit that is formed on the support stand to detect an approach of an object; and

a control unit for controlling the power source unit by recognizing a pre-determined command corresponding to a detection signal from the approaching detection unit.

2. The display system according to claim 1, wherein the approaching detection unit is a non-contact key input unit.

3. The display system according to claim 1, wherein the support stand is provided with a space for allowing the approach of the object to be detected by the approaching detection unit.

4. The display system according to claim 1, wherein the object is a part of a human body or other objects.

5. The display system according to claim 1, wherein the command includes a power-on/off command.

6. The display system according to claim 1, wherein the control unit controls the power source unit after removing a noise component using a predetermined logic interval of a detected signal.

7. The display system according to claim 1, wherein the control unit detects an input error of the command using a predetermined logic interval of a detected signal after recognizing the command.

8. The display system according to claim 1, further comprising a light emission unit including at least two light sources to which driving voltages is input from the power source unit, wherein the control unit notifies an input error of the power-on/off command by controlling a light emitting pattern of the light emission unit when the input error of the power-on/off command is detected.

9. The display system according to claim 1, wherein The support stand is provided with a light emission unit whose light emitting pattern varies according to an operating mode of the display system.

10. The display system according to claim 1, wherein the approaching detection unit includes an approaching detection element for detecting the approaching of the object and a logic normalization part for generating a detected signal by normalizing an output of the approaching detection element.

11. The display system according to claim 1, wherein the approaching detection element is one of an infrared detection sensor and an electrostatic conductive plate depending on whether electric charges are discharged.

12. The display system according to claim 1, wherein the space is defined by a through hole horizontally penetrating the support stand.

13. The display system according to claim 1, wherein the space is defined by a concaved portion concaved rearward of the support stand.

14. A method of controlling a power of a display system, the method comprising:

generating a signal when an object approaches;

recognizing a predetermined command corresponding to the generated signal; and

controlling a power source unit for supplying a driving voltage to a display unit in accordance with the recognized command.

15. The method according to claim 14, wherein the recognizing of the predetermined command includes removing noise based on a predetermined logic interval of the generated signal and recognizing a power-on/off command in accordance with the predetermined logic interval.

16. A method of controlling a power of a display system, the method comprising:

recognizing a power-on/off command as an object approaches;

controlling a power source unit for supplying a driving voltage to a display unit in accordance with the recognized power-on/off command; and

controlling a light emitting pattern of a light emission unit in accordance with the recognized power-on/off command.

17. The method according to claim 16, wherein the object is a part of a human body.

18. The method according to claim 16, wherein the recognizing of the power-on/off command includes detecting an input error of the power-on/off command based on a predetermined logic interval.

19. The method according to claim 16, wherein the controlling of the light emitting pattern includes, when an input error of the power-on/off command is detected during the recognizing of the power-on/off command, informing of the input error of the power-on/off command by allowing the light emission unit to emit light in a specific light emitting pattern.

20. A display system comprising:

a display unit for displaying an image;

a support stand for supporting the display unit;

a power source unit for supplying power to the display unit;

an approaching detection unit that is formed on the support stand to detect an approach of an object; and

a control unit for controlling the power source unit by recognizing a pre-determined command corresponding to a detection signal from the approaching detection unit,

wherein the object is a part of a human body.
