Most of the users are entangled in whether to use a splicing screen with 1.7mm stitching or a splicing screen with 3.5mm stitching. Take the 55-inch 1.7mm splicing seam and 3.5mm splicing seam as an example. In fact, in terms of product dimensions, the difference between the two is not obvious. The 3.5mm splicing screen is only slightly larger by two or three millimeters. If you don't measure carefully, the two models are almost the same size.
