With development after the LED display technology, the LED in the studio and television is increasingly used in large-scale activities, as the activity background wall, it provides a variety of vivid, brilliant background images and more interactive features, make the background images also move also static, the performances and background together, perfectly to the scene and show the atmosphere of the fuses in together, implements the function and effect of other stage arts equipment is difficult to achieve.However, in order to give full play to the advantages of LED display, the following aspects should be paid attention to in the selection and use process:

1. Proper shooting distance

As mentioned in the previous discussion on point spacing and filling coefficient, LED screens with different spacing and filling coefficient have different shooting distances.Take the LED display with 4.25mm point spacing and 60% filling coefficient as an example, the distance between the subject and the screen should be 4-10 meters, so as to get a better background picture when shooting the subject.If the character is too close to the screen, the background will appear grainy when taking a close shot, and it is also easy to produce the interference of reticulation.

Keep the spacing as small as possible

Point spacing is the distance between the center points of adjacent pixels on the LED screen.The smaller the spacing, the more pixels per unit area, the higher the resolution, the closer you can shoot, and of course the more expensive it is.At present, the LED screen used in domestic TV studios is mostly 6-8 mm in point spacing. The relationship between the resolution of signal source and point spacing should be carefully studied to achieve consistent resolution and point-to-point display, so as to achieve the best effect.

3. Color temperature adjustment

When the studio USES LED screen as the background, its color temperature should be consistent with the color temperature of the lighting in the studio, so as to obtain accurate color reproduction in shooting.According to the needs of the program, the lighting of the studio sometimes USES 3200K low color temperature lamps, and sometimes USES 5600K high color temperature lamps, and the LED display needs to be adjusted to the corresponding color temperature, so as to obtain a satisfactory shooting effect.

4. Ensure a good use environment

LED screen life and stability are closely related to the working temperature.If the actual operating temperature exceeds the specified range of use of the product, not only its life will be shortened, the product itself will be seriously damaged.Also, the threat of dust cannot be ignored.Too much dust, will make the led screen thermal stability decline or even electricity leakage, serious will lead to burning;Dust will also absorb moisture, which corrodes the electronic circuit, resulting in some not easy to check the short circuit problem, 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;It has a good consistency, can ensure the indiscriminate display of the screen;Box size small, easy to form a smooth background screen modeling;Color gamut coverage is higher than other display products;It has the advantage of better weak reflection, high reliability and low maintenance cost.

Of course, the LED screen with so many advantages must also be used well to make its advantages fully displayed.Therefore, when using LED screens in TV programs, we should select appropriate LED screens, deeply understand their characteristics, and select technical products as the background according to different studio conditions, program forms and requirements, so that these new technologies can give full play to their advantages.
