LED screens are more and more popular in TV studios. However, during the use of LED screens, the effect of TV pictures is very different. Some pictures are bright, clear and stable from beginning to end; This requires us to pay attention to several issues in the selection and use of LED screens.
The shooting distance should be appropriate
As mentioned earlier when talking about the dot pitch and fill factor, LED screens with different dot pitch and fill factor have different shooting distances. Taking an LED display with a dot pitch of 4.25 mm and a fill factor of 60% as an example, the distance between the person being photographed and the screen should be 4-10 meters, so that a better background picture can be obtained when shooting people. If the person is too close to the screen, when shooting close-up shots, the background will appear grainy, and it is easy to produce mesh interference.
Adjust the color temperature
When the studio uses the LED screen as the background, its color temperature should be consistent with the color temperature of the lighting in the studio, so that accurate color reproduction can be obtained during shooting. According to the needs of the program, the lighting of the studio sometimes uses 3200K low color temperature lamps, sometimes 5600K high color temperature lamps, and the LED display needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results.
Ensure a good use environment
The life and stability of the LED screen are closely related to the working temperature. If the actual working temperature exceeds the specified use range of the product, not only its life will be shortened, but the product itself will also be seriously damaged. In addition, the threat of dust cannot be ignored. Too much dust will reduce the thermal stability of the LED screen and even cause leakage, which will lead to burnout in severe cases; dust will also absorb moisture, which will corrode electronic circuits and cause some short-circuit problems that are not easy to troubleshoot, so pay attention to keep the studio clean.
The LED screen has no seams, which can make the picture more perfect; the power consumption is lower, the heat is smaller, energy saving and environmental protection; it has good consistency, which can ensure the indiscriminate display of the picture; the size of the box is small, which is convenient for the background screen to form a smooth shape ; The color gamut coverage is higher than other display products; it has the advantage of better weak reflection characteristics, and has high operational reliability and low post-operation and maintenance costs.
Of course, the LED screen with so many advantages must also be used well in order to make its advantages fully manifested. Therefore, when using LED screens in TV programs, we need to choose suitable LED screens, understand their characteristics in depth, and choose technical products as the background for different studio conditions, program forms and requirements, so that these new technologies can maximize their use Advantages.
