Background

The widespread use of high-tech technology has led to unprecedented developments in social productivity and economy into the 21 st century. The lightweight and compact LCD-LCD displays have become the center of people enjoying information and multimedia content instead of the traditional bulky CRT-CRT display. However, in the using process of the liquid crystal display, the inventor finds that the liquid crystal display can only be fixedly placed on a desktop and cannot adjust the up-down space height, the left-right position or the pitching angle of the display according to real-time requirements.

Currently, the user's display is typically mounted on a fixed mount that can only be adjusted to a small extent in the direction of the elevation viewing angle. From the perspective of ergonomics, since the heights of users are different, the heights of a workbench and a seat are often difficult to match with the heights of the users, so that the fatigue of wrists, arms and shoulders is often generated when the users are engaged in keyboard operation for a long time, and the users can keep a comfortable and natural working posture when watching the display for a long time and trying to improve the working efficiency and the healthy work. Therefore, there is a need in the market for a display stand having adjustable height and tilt viewing angle.
