Self-tapping bolts are most likely to corrode and rust after long-term use. This also makes it inconvenient for workers to disassemble and use the LED module frame later. Therefore, there are certain shortcomings.

In summary, it is necessary to invent an LED module frame and an LED display screen.

Damping card grooves 110 are opened at the top of the outer wall of the frame assembly rod 100 and close to the inner side. The four damping card grooves 110 are connected to each other. The damping card grooves 110 are opened to connect the bottom end of the square card plate 300 so that the square card plate 300 can initially fix the four frame assembly rods 100. The square card plate 300 is set in a square frame shape, and the cross-section is set in an inverted U shape. The cross-section of the square card plate 300 is set in an inverted U shape in order to better clamp on the inner wall of the damping card groove 110. The bottom end of the outer wall of the square card plate 300 is slidably connected to the inner wall of the damping card groove 110, and the square card plate 300 and the damping card Damping needs to be set between the grooves 110 to increase the friction between the two, so as to improve the stability of the subsequent square card plate 300 splicing the four frame rods 100.
