Technical Field
[0001] This utility model relates to the field of display screen technology, and in particular to a stereoscopic liquid crystal display module. Background Technology
[0002] With the rapid development of display technology, 3D LCD screens have been widely used in exhibitions and displays. In exhibition halls, museums, science and technology museums, and other display scenarios, the screens not only need to provide high-quality visual presentations, but also need to have features such as flexible adjustment, stable support, and easy maintenance to meet different exhibition needs. However, traditional screen brackets or fixing devices often have the following technical defects:
