The present invention relates to a display lift apparatus for a table and a system thereof, and more particularly, to form a lift in the upper plate of a desk and provide a lift device such that the display is lifted through the lift, and selectively display the display as needed. The present invention relates to a display elevating device and a system for elevating the upper surface of the table to optimize the use area of the desk, as well as improving the efficiency of learning and work by centrally controlling a table having a plurality of elevating devices.

Generally, a computer has a monitor, a main body, a keyboard, etc., and there is a computer desk for installing such a computer exclusively. However, in an office in which many workers live in one space, a separate computer is required due to the limitation of space. No computer desk is provided, and the computer is used in a general office desk.

As described above, a monitor of a computer installed in a general office desk has a problem in that the user cannot use the desk as much as the space occupied by the monitor because the user usually locates the screen.

In order to solve this problem, a desk has been developed in which a monitor is stored in a storage space formed under the top of the desk so that the screen of the monitor can be viewed through the upper surface of the desk. .

Due to the above problems, although liquid crystal (LCD) monitors have been used in recent years, such liquid crystal monitors have the advantage that they are smaller in volume than conventional monitors (CRT method), but like the liquid crystal monitors, Since there is still a problem in reducing the use of the desk.

Accordingly, a number of lifting devices for storing the monitor in a storage space of a desk and vertically elevating have been developed. The conventional vertical lifting device mainly utilizes a rope or a screw shaft as a means for elevating and monitoring a monitor.
