During playing, the 3D polarizing film 2 polarizes the LED lamp bead, so that the played video is converted into a 3D video.

[0044] Specifically, the strip-shaped 3D polarized film 4 is arranged in a strip shape, so that the covering is faster, and whether it has an influence on the sound transmission hole 102 does not need to be considered.
[0045] Further, the independent polarized film 3 comprises a plurality of film bodies 304, the upper surface of the film body 304 is fixedly connected with an independent left eye polarized film 301, the upper surface of the film body 304 is fixedly connected with an independent right eye polarized film 303, and a through hole 302 is formed in the surface of the film body 304.
[0046] Specifically, the independent polarized film 3 is arranged in pairs, so that when covering, the influence between the pairs can be avoided, and the overall error during covering can be minimized.

[0049] Further, the shape and position of the sound transmission hole 102 and the sound transmission hole 502 are not limited.
[0050] Different sizes and different shapes of the sound transmission hole 102 have different characteristics, and can be specially arranged according to the distance and size of the lamp beads, so that the sound transmission hole 102 can have better sound performance and the LED lamp bead can have better optical performance.
[0051] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
