[0040] Example 2:

[0041] The following are the unfolding steps of this utility model's portable roll-up LED display screen: Preparation: Place the base on a stable surface, ensuring that the two cup feet and two casters at the bottom of the base are in stable contact with the ground to prevent wobbling during unfolding. Install the support rods: Take out two support rods and install them at the installation positions on both ends of the linear hole at the top of the base, ensuring that the support rods are installed firmly and will not wobble easily. Extending the display screen: Hold the top beam assembly and pull upwards. The top beam assembly will pull the display screen out of the linear hole in the base. During the pulling process, because the display screen is a foldable screen and its first end is fixed to the roll frame, the roll frame will rotate as the display screen is pulled out. Adjust the support rod length: Adjust the length of the two support rods to achieve the appropriate height according to the display requirements. Because the support rods are telescopic rods, their length can be adjusted by stretching or compressing them. Fixing the top beam assembly: Align the two ends of the top beam assembly with the slots at the top of the two support rods, and then snap the top beam assembly into the slots to ensure that the top beam assembly is securely installed. At this point, the display screen is fully unfolded and in a taut state, and the unfolding process is complete. Example 3:

[0042] The following are the steps for storing this convenient roll-up LED display screen: Disassemble the top beam assembly: Remove the top beam assembly from the slot at the top of the two support rods to separate the top beam assembly from the support rods. Retracting the display screen: Slowly release the top beam assembly. Under the rotation of the drum frame, the display screen will gradually wind back onto the drum frame. During the winding process, appropriate assistance can be provided to guide the display screen to ensure that it is wound neatly and to avoid wrinkles or uneven winding. Shorten the support rods: Shorten the length of the two support rods to their shortest possible length for easier storage. Complete storage: Check that the display screen has been completely rolled back into the roll frame and stored in the storage space of the base. Then, place the disassembled support rod into a suitable storage location. The storage process is now complete.

[0043] In summary, the display screen of this utility model is a foldable screen that can be rolled up on a cylindrical frame, greatly reducing its volume when stored. Furthermore, the support rod is detachable, making it easy to carry and transport, thus improving the convenience of use. This utility model is equipped with an LED control module and a power supply module, which can effectively control and supply power to the display screen, ensure the normal operation of the display screen, have dynamic display function, and achieve better publicity effect. The connection structure between the various components of this utility model is reasonably designed, such as the clamp plate fixing the display screen, the rotating shaft bracket and the rotating shaft realizing the rotation of the drum frame, and the top beam assembly and the support rod being snapped together, which makes the overall structure stable and reliable, and convenient and quick to install and disassemble.
