The first side 1311 corresponds to the upper frame 111, the second side 1312 corresponds to the lower frame 112, the third side 1313 corresponds to the left frame 113, and the fourth side 1314 corresponds to the right frame 114. The first surface 1321 and the second surface 1322 are opposite. The first fixing assembly 132 comprises a plurality of fixing members, which are evenly spaced and disposed throughout the first side 1311 of the film body 131. The plurality of fixing members are disposed on the first guide rail bracket 121. The winding tube 133 is used to roll up the film body 131. The winding tube 133 is located at the third side 1313 of the film body 131, is disposed at the left frame 113, and is fixedly connected to the back frame 15. The bottom rod 134 is located at the fourth side 1314 of the film body 131 and is used to maintain the film body 131 unfolded to cover the light box 14. In a specific embodiment, the PET film 13 also includes a second fixing assembly located at the second side 1312 of the film body 131. The second fixing assembly can slide on the second guide rail bracket 122. The first and second fixing assemblies allow the film body 131 to slide along the first and second guide rail brackets from the right frame 114 of the front frame 11 to the left frame 113 on the fourth side 1314, thereby retracting the film body 131 to the left frame 113. Before the fourth side 1314 of the membrane body 131 is retracted from the right frame 114 toward the reel tube 133, the second side 1322 of the membrane body 131 adheres to and covers the light box 14. When the fourth side 1314 of the membrane body 131 is retracted from the right frame 114 toward the reel tube 133, the bottom bar 134 follows the fourth side 1314 of the membrane body 131 as it moves from the right frame 114 toward the reel tube 133. In a specific implementation, the reel tube 133 can be secured to the back frame 15 using a spring-loaded retraction device, which automatically retracts the membrane body 131 during repeated stretching.

In specific implementation, refer to Figure 1 As shown, the display module 100 is in an assembled state; Figure 6 As shown, the user removes the right frame 114 of the front frame 11 and pushes the hook 151 toward the light box 14 to disengage the hook 151 from the slot 1341, so that the slot 1341 of the bottom rod 134 is no longer fixed by the hook 151 and can move toward the left frame 113; Figure 7 As shown, under the pulling force of the coil tube 133, the membrane body 131 moves toward the left frame 113 and partially exposes the light box 14; Figure 8 As shown, the film body 131 is retracted into the winding tube 133, completely exposing the light box 14. The left frame 113 and the right frame 114 can be removed together. The left frame 113 can also be removed after the film body 131 is reeled up, but this is not a limitation. The winding tube 133 is then removed from the back frame 15, and the light box 14 is removed from the back frame 15 for easy maintenance.
[0033] In an embodiment of the present invention, the first fixing assembly 132 includes multiple fixing members that penetrate the first surface 1321 and the second surface 1322. Multiple fixing members protrude from the first surface 1321 at the first edge 1311 of the membrane body 131 in the form of a first hemisphere, and multiple fixing members protrude from the second surface 1322 at the first edge 1311 of the membrane body 131 in the form of a second hemisphere.
