[0002] The LED transparent screen support structure is a structural system that provides physical support, fixation, and stability for the LED transparent display screen. It is mainly used to support the weight of the display module, circuit components, etc., to ensure that the screen maintains its intended shape, position, and safety in the installation environment. At the same time, it must meet the light transmittance requirements so as not to affect the transparent display effect of the screen. The LED transparent screen support structure requires welding.
