Difference between 3d and 5d Mummy Mask

There is no difference between 3d and 5d films. Tempered film is a curved full-screen tempered film starting from 3D, which is the type above 3D. It's just that the names are different, but some manufacturers have their own unique names, such as 5d and 6d, which are essentially the same. Above 3D, there is only the full-screen coverage of the curved surface, which is no different from the product of 5D in quality.
