With the introduction of small spacing LED screen, LED screen in the radio and television industry more and more applications.
1. The shooting distance should be appropriate
As mentioned earlier in terms of point spacing and fill factor, different spacing, different fill factor LED screen, the appropriate shooting distance is not the same. To point spacing of 4.25 mm, fill the coefficient of 60% of the LED display, for example, the distance between the characters and the screen in the 4-10 meters more appropriate, so when shooting people can get a better background picture. If the characters from the screen too close, shooting close-range, the background will appear grainy, but also prone to moire interference.
2. Point spacing should be as small as possible
The dot pitch is the distance between the center points of the adjacent pixels of the LED screen. The smaller the pitch, the more pixels per unit area, the higher the resolution, the closer the shooting distance, and the more expensive the price will be. At present, the dot pitch of the LED screen used in the domestic television studio is 6-8 mm, and the relationship between the resolution and the point spacing of the signal source should be carefully studied, so that the resolution is consistent and the point-to-point display is achieved Good effect.
3. Color temperature can be adjusted
Studio use LED screen as the background, the color temperature should be consistent with the studio light color temperature, in order to get accurate color reproduction in the shooting. Studio lighting according to program needs, sometimes use 3200K low color temperature lamps, sometimes use 5600K high color temperature lamps, LED display will need to adjust to the corresponding color temperature, in order to obtain a satisfactory shooting.
4. Ensure a good use of the environment
LED screen life and stability are closely related with the working temperature. If the actual operating temperature exceeds the scope of use of the product, not only its life will be shortened, the product itself will be seriously damaged. In addition, the threat of dust can not be ignored. Dust too much, will lead to thermal stability of the led screen or even produce leakage, serious will lead to burn; dust will absorb moisture, thus corrosion of electronic circuits, causing some difficult to troubleshoot short circuit problems, so pay attention to keep the studio clean.
LED screen without patchwork, can make the picture more perfect; lower power consumption, less heat, energy saving and environmental protection; its good consistency, to ensure that the screen no difference display; box size is small, easy to form a smooth background screen shape ; Color gamut coverage is higher than other display products; have a better weak reflective characteristics of the advantages, and high reliability, late operation and maintenance costs low.
