Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a multi-size LED display testing and adjustment frame. Background Technology

[0002] An LED display screen is a flat panel display composed of multiple small LED module panels, capable of displaying various information such as text, images, and videos. It combines microelectronics, computer technology, and information processing technology, possessing advantages such as vibrant colors, high brightness, and long lifespan, and is widely used in commercial media, cultural performances, sporting events, and many other fields.

[0003] Currently, large LED displays are typically composed of multiple LED display panels. To ensure display quality, it is essential to strictly control key parameters such as the flatness of these display panels, pixel center distance deviation, and horizontal and vertical misalignment. Therefore, comprehensive performance testing of LED displays before shipment is necessary, which usually requires the use of specific brackets to secure the displays for testing.

[0004] However, traditional testing stands have significant limitations: most are fixed-size designs, only suitable for LED displays of specific sizes. When testing displays of different specifications, a stand of the appropriate size must be replaced, a process that is not only time-consuming but also increases costs. Furthermore, the need to prepare stands of various sizes to accommodate different testing requirements also leads to resource waste. Summary of the Invention
