Abstract

Provided is a method for installing a display device including an operation of assembling a step adjusting module for controlling a displacement adjuster of a first cabinet onto a rear surface of the first cabinet, an operation of fastening the first cabinet to a mount on an installation surface, an operation of fastening a first display module to a front surface of the first cabinet, an operation of coupling, to the first display module and a second display module, sensor module including a first displacement sensor positioned on the front surface of the first display module and a second displacement sensor positioned on a front surface of the second display module adjacent to the first display module, a sensing operation of measuring a value of the first displacement sensor and a value of the second displacement sensor, and an adjusting operation of adjusting a gap between the first cabinet and the first display module by controlling the step adjusting module such that the value of the first displacement sensor is equal to the value of the second displacement sensor when the value of the first displacement sensor and the value of the second displacement sensor are different from each other.

First claim

What is claimed is:

1. A method for installing a display device, the method comprising:
an operation of assembling a step adjusting module for controlling a displacement adjuster of a first cabinet onto a rear surface of the first cabinet;
an operation of fastening the first cabinet to a mount on an installation surface;
an operation of fastening a first display module to a front surface of the first cabinet;
an operation of coupling, to the first display module and a second display module, a sensor module including a first displacement sensor positioned on the front surface of the first display module and a second displacement sensor positioned on a front surface of the second display module adjacent to the first display module;
a sensing operation of measuring a value of the first displacement sensor and a value of the second displacement sensor; and
an adjusting operation of adjusting a gap between the first cabinet and the first display module by controlling the step adjusting module such that the value of the first displacement sensor is equal to the value of the second displacement sensor when the value of the first displacement sensor and the value of the second displacement sensor are different from each other.

2. The method of claim 1 , further comprising an operation of removing the step adjusting module and the sensor module after the adjusting operation.

3. The method of claim 1 , wherein the gap between the first display module and the first cabinet increases when the value of the first displacement sensor is greater than the value of the second displacement sensor,
wherein the gap between the first display module and the first cabinet decreases when the value of the first displacement sensor is smaller than the value of the second displacement sensor.

4. The method of claim 1 , wherein the sensor module includes:
a sensing jig;
a first sensor module having the first displacement sensor and the second displacement sensor arranged in a horizontal direction on the sensing jig; and
a second sensor module having the first displacement sensor and the second displacement sensor arranged in a vertical direction on the sensing jig.

5. The method of claim 4 , wherein a plurality of first sensor modules are arranged in the vertical direction on the sensing jig,
wherein a plurality of second sensor modules are arranged in the horizontal direction on the sensing jig.

6. The method of claim 4 , wherein the first sensor module is located on a boundary line between the first display module and a horizontally neighboring second display module,
wherein the second sensor module is located on a boundary line between the first display module and a vertically neighboring second display module.

7. The method of claim 4 , wherein the sensor module includes a third sensor module including the first displacement sensor and three second displacement sensors respectively positioned in the vertical direction, the horizontal direction, and a diagonal direction.

8. The method of claim 1 , wherein the display device includes:
a first fastening portion positioned on a rear surface of the first display module; and
a second fastening portion screwed to the first cabinet and coupled to the first fastening portion,
wherein the displacement adjuster includes a leveling gear fastened to an end of the second fastening portion protruding toward the rear surface of the first cabinet.

9. The method of claim 8 , wherein the step adjusting module includes:
an adjustment gear engaged with the leveling gear; and
a motor for transmitting a rotational force to the adjustment gear.

10. A system for installing a display device for installing a first cabinet with a first display module coupled to a front surface of the first cabinet, the system comprising:
a step adjusting module for controlling a displacement adjuster of the first cabinet;
a sensor module including a first displacement sensor positioned on a front surface of the first display module and a second displacement sensor positioned on a front surface of a second display module adjacent to the first display module; and
a controller configured to adjust a gap between the first cabinet and the first display module by controlling the step adjusting module such that a value of the first displacement sensor is equal to a value of the second displacement sensor when the value of the first displacement sensor and the value of the second displacement sensor are different from each other.

11. The system of claim 10 , wherein the gap between the first display module and the first cabinet increases when the value of the first displacement sensor is greater than the value of the second displacement sensor,
wherein the gap between the first display module and the first cabinet decreases when the value of the first displacement sensor is smaller than the value of the second displacement sensor.

12. The system of claim 10 , wherein the sensor module includes:
a sensing jig;
a first sensor module having the first displacement sensor and the second displacement sensor arranged in a horizontal direction on the sensing jig; and
a second sensor module having the first displacement sensor and the second displacement sensor arranged in a vertical direction on the sensing jig.

13. The system of claim 12 , wherein a plurality of first sensor modules are arranged in the vertical direction on the sensing jig,
wherein a plurality of second sensor modules are arranged in the horizontal direction on the sensing jig.

14. The system of claim 12 , wherein the first sensor module is located on a boundary line between the first display module and a horizontally neighboring second display module,
wherein the second sensor module is located on a boundary line between the first display module and a vertically neighboring second display module.

15. The system of claim 12 , wherein the sensor module includes a third sensor module including the first displacement sensor and three second displacement sensors respectively positioned in the vertical direction, the horizontal direction, and a diagonal direction.

16. The system of claim 10 , further comprising:
a first fastening portion positioned on a rear surface of the first display module; and
a second fastening portion screwed to the first cabinet and coupled to the first fastening portion,
wherein the displacement adjuster includes a leveling gear fastened to an end of the second fastening portion protruding toward the rear surface of the first cabinet.

17. The system of claim 16 , wherein the step adjusting module includes:
an adjustment gear engaged with the leveling gear; and
