As we all know, LED displays with different pixel pitches, filling factors, and shooting distances are not the same. Take, for example, a 3 mm pixel pitch LED display with a filling factor of 60%; the distance between the background LED display and the compere (or other people or stuff) should be 3m or more to get a reasonably good background. If the compere is too close to the background LED display, it will appear grainy and have water ripples.

In an LED display, pixel pitch is the distance between two neighboring pixels. The lower the pixel pitch, the more pixels per unit area, the higher the resolution, and the closer the shooting distance.Of course, the price is higher as well. The pixel pitch of LED displays used in TV studios in the United States is currently 4-10mm.As a result, we must carefully examine the resolution of the source signal as well as the pixel pitch of the back ground LED display.And we will do our best to make the two the same, which will lead to dot to dot showing.
