The narrow edge LCD splicing display system mainly has two specifications: 40 inch and 46 inch.

Firstly, it should be calculated from the height and width of the room.

For example, the reserved area for an indoor display wall is 8.8 meters wide and 3.2 meters high.

First subtract the bottom support height of about 1 meter from the height, and 3.2-1 meter equals 2.2 meters.

Next, you need to select the display size based on the display height. For a 16:9 display specification, the 40 inch size is 912mm * 524mm * 60mm; The size of 46 inches is 1026mm * 580mm * 56mm.

Based on this basic size, we calculate the number of stacked layers. 40 inches: 2200 ÷ 524 ≈ 4, with a maximum of 4 layers. 46 inches: 2200 ÷ 580 ≈ 3, with a maximum of 3 layers. Next, we need to confirm the display width. 8.8 meters is the net size of the room, and the display area should be in the middle. We need to subtract at least 3 meters from the width of the doors or decorations on both sides. This means that the width of the actual wall is at most 5.8 meters. At this point, we can calculate the number of displays arranged, which is 40 inches: 5800 ÷ 912 ≈ 6, with a maximum of 6 columns; 46 inches: 5800 ÷ 1026 ≈ 5, with a maximum of 5 columns.

In this way, the theoretical splicing scale comes out: 40 inches, 4 × 6; 46 inches, 3 x 5.

Next, we are going to make a choice. Suitable options for 40 inches: 2 × 2, 2 × 3, 2 × 4, 2 × 6, 3 × 2, 3 × 3, 3 × 4, 3 × 6, 4 × 4, 4 × 6;

Suitable options for 46 inches: 2 × 2, 2 × 3, 2 × 4, 3 × 2, 3 × 3, 3 × 4, 3 × 5.

If it is for displaying a single image on a large video surveillance screen or high-resolution images in the command and dispatch room, it is recommended to choose the appropriate specifications, generally 2 × 2, 3 × 3, 4 × 4. As it is a 16:9 display screen, the general principle for selecting is column count ≤ row count, otherwise the graphics will be displayed in a flattened shape.

If it is only a single screen display without the purpose of combined enlargement display, its splicing scale can be designed according to the maximum size.

In this example, a more suitable option for the entire wall is: 3 × 3, 46 inches; 4 x 4, 40 inches.

The best principle of choosing between two generally follows the principle of prioritizing larger sizes under the same area, because larger sizes have fewer splicing gaps and a simpler overall style.

Another option is to display multiple images on the same plane, which is generally used in situations where there are a large number of video surveillance footage.
