[0001] The utility model relates to the technical field of LED full-color display screens, and specifically relates to an LED full-color display screen with a stable base. Background Technique

[0002] In today's digital age, the ways of advertising and information dissemination are undergoing huge changes. As a new medium, the full-color LED display screen has become the first choice for many enterprises and organizations to display their images, promote products and services with its advantages such as high brightness, high contrast, high color saturation and high refresh rate. The more the full-color LED display screen is applied, the higher the demand for its functions.

[0003] Since the LED full-color display screen is often directly placed on the operating table during actual operation and generally does not have a base that can be quickly and stably fixed, this results in it being easily collided and toppled. Or for some display screens that can adjust the height and tilt angle, there are also problems of low stability during adjustment. Moreover, its display screen is often an independent and single structure and is not easy to be folded and deformed in multiple screens, which leads to poor display effects and can no longer meet people's needs. For this reason, we propose a new type of LED full-color display screen with a stable base to solve the above-mentioned defects. Content of the Utility Model
