Description

Automatic Leveling LED Display System and Method for Automatic Leveling of LED Display The present invention relates to the field of LED display technology, and more specifically to a technology that automatically adjusts the flatness of an LED module to maintain the quality of the display and simplifies the installation and maintenance process. LED displays are widely used for various commercial and public purposes. They play a crucial role in large billboards, sports stadiums, and stage backdrops due to their ability to provide high-definition image quality and high brightness. These LED displays consist of numerous LED modules, each connected to a fixed frame (or cabinet) to form the entire display. Meanwhile, minute height differences (steps) between LED modules impair the flatness of the display and cause image quality degradation. If flatness is not maintained, distortion or shadows appear on the screen, which not only degrades the viewing experience but also reduces advertising effectiveness. This is particularly pronounced in large displays, further emphasizing the importance of maintaining flatness. Generally, manual adjustment methods are utilized to maintain flatness during the installation of LED displays. This method involves a technician manually adjusting the height of each module to achieve flatness. However, this process is time-consuming, requires skilled technicians, and may result in inconsistent accuracy. While this manual approach requires skilled personnel, it has the disadvantage of increasing installation time and maintenance costs. Furthermore, adjustment results can vary depending on the operator's proficiency, and fatigue caused by prolonged work is also cited as a problem. As such, conventional technology has limitations in efficiently resolving step height issues that occur during maintenance after installation, as it relies on detecting step heights between LED modules in advance and adjusting them manually. Even if flatness is maintained during the initial installation, step heights may occur over time due to changes in the external environment or deformation of the modules themselves. This requires periodic maintenance work, which leads to additional costs and labor consumption.
