As we mentioned before, the shooting distance ranging from different pixel pitches and , different filling coefficient of the LED screen. To take a LED display with 4.25mm pixel pitch, 60% filling coefficient for example, the best distance between the host and the screen is 4-10 m, so that we can get a better background images. If the host is too close to the screen, audiences will feel grain and moiré sometime. 

Pixel pitch means the distance between the adjacent pixels in a LED screen center. The smaller pixel pitch your LED display adopted, the higher resolution ratio and the closer shot distance you can get. Although the price is more expensive, it still has no affect on the adoptions in some domestic TV studio. At present domestic television studio use LED screen spacing of 4 - 6 mm.

When use LED screen as a background, when its color temperature should be consistent with the studio light color temperature, we can get the exact color reproduction. According to the program requirements, the studio lights sometimes use 3200 k low color temperature of lamps while sometimes high 5600 k color temperature of lamps and you need to adjust the LED display to the corresponding color temperature, to obtain satisfactory results.

The life and stability of the LED screen has close relationship with working temperature. If the actual working temperature exceeds, not only will shorten its life, the product itself can also get severely damaged. In addition, we cannot ignore the threat of dust too. Too much dust will threat the LED screen thermal stability even causes leakage, serious will cause burning. Dust will absorb the moisture and corrode of electronic circuit, some short circuit problems are not easy to check out, so we must keep the room clean.
