In general, while watching TV is one of the main entertainment activities and sources of information for people, watching TV in a fixed location for a long time makes the body uncomfortable, and such as periarthritis of the scapular humerus, low back pain, spondylosis, and sciatic nerve pain. May cause disease.

In order to solve this problem, efforts have been made to allow people to comfortably enjoy rich and colorful TV programs.

Accordingly, in recent years, people can comfortably watch TV by remotely or manually adjusting the height and time of the TV set according to the viewing angle at the position of lying or sitting in order to position the TV set within the optimal view.

There is a demand for a display position control device that satisfies the requirements that can be used to treat the above diseased patients and hospital bed patients.

As a prior art related to the existing display position control device, as disclosed in Korean Patent Registration No. 10-0521359 "TV receiver position control device" (registration date; 2005.10.06), the viewer turns the TV receiver according to the viewing posture of the viewer. It can be moved to a desired height to match the eye level, and also can be viewed at an appropriate angle by adjusting the angle.

The above device can be moved to a desired height to match the viewer's eye level by the screw drive motor and the rotating motor, and can be controlled by remote control so that the angle can be adjusted and viewed at an appropriate angle. However, there is a disadvantage that only the tilting angle of the TV set can be adjusted.

As other prior art related to the position adjusting device for an existing display device, as disclosed in Korean Patent Publication No. 10-1848619, "Winch-type display position adjusting device" (registration date: 2018.04.09), a curved chain is used as a feature. As a result, the viewing height of the display can be easily adjusted, and the load of the display can be relatively reduced to facilitate the movement of the display. However, the display can only be moved up and down, and the left and right sides of the display can be moved up and down. And there is a disadvantage that the vertical angle cannot be adjusted.

As another prior art related to the existing display device position control device, as disclosed in Korean Patent Publication No. 10-1012002 "Position Control Device for Wall-mounted Flat Panel Display Device" (Registration Date: 2011.01.25), it is economical and load-bearing. This small size is applied to both large and small flat-panel displays. In particular, it has the advantage of securing a wide viewing angle because it is easy to move the position up and down as well as the front and rear, left and right up and down. As a result, product durability may be deteriorated, and if the rotation of the display does not occur, there is a concern that sagging may occur due to the self-weight of the display.

There is a disadvantage in that the display's sagging occurs while the display's weight load is heavy while the conventional wall-mounted display is rotated by tilting angles, and the driving load of the motor is generated in the return operation of the display.

Existing flat panel display panels have limitations in their applications and uses because they use inflexible glass substrates.

Accordingly, in recent years, a flexible display device that can bend using a flexible substrate such as plastic or the like instead of a non-flexible glass substrate has been attracting attention as a new display device.

Recently, research and development on a rollable display device capable of winding a flexible panel like a roll has been actively conducted.

For example, in U.S. Patent Publication No. 2013-0127799, a display device having a rollable display unit is known. The prior art document uses a drive motor to wind or unfold a rollable display unit.

Other prior art related thereto include a display panel including a pixel array for displaying an image, as disclosed in Korean Patent Publication No. 10-1649097 "Rollable Display Device" (Registration Date: 2016.08.11); And a roller part on which the display panel is wound, wherein the roller part comprises: a first semi-cylindrical part and a second semi-cylindrical part coupled in a cylindrical tube shape; And a slit provided at one end portion at which the first and second semi-cylindrical portions are coupled to each other and into which the inside of the display panel is inserted, and the first semi-cylindrical portion has an outer circumferential surface having a first curvature and a first curvature smaller than the first curvature. It has an inner circumferential surface of 2 curvature, and the thickness between the inner circumferential surface and the outer circumferential surface of the first semi-cylindrical part is thicker from one end to the other, and has the advantage of easy winding and unwinding of the display panel. There is a disadvantage in that it is not possible to adjust the height of the lens or maintain a tilting angle suitable for the user's eyes.

In addition, the conventional display device has a disadvantage in that the volume becomes relatively large in order to provide the various functions described above, and thus there is a disadvantage that it is unsuitable for a wall-mounted display device.
