Choosing Your TV studios and broadcast LED Video Wall

  With the development of LED display technology, LED video wall is increasingly used in TV studios and television broadcast large-scale activities, as the background wall, it provides a variety of vivid, dazzling background screen and more interactive function, so that the performance and background integration, perfect the scene and the atmosphere of the program together, Realize the other Stage art equipment difficult to achieve the function and effect.

  However, to play the advantages of LED display, selection and use of the process to pay attention to the following aspects:

  1. The shooting distance should be suitable Different spacing, different filling coefficient of the LED screen, the appropriate shooting distance is not the same. With a point spacing of 4.25 mm, filling coefficient of 60% LED display screen For example, the person being photographed and screen between the distance between 4-10 meters is more appropriate, so when shooting characters can get a better background screen.

  If the character is too close to the screen, in the shot close-up, the background will appear particle feeling, but also easy to produce ripple interference.

  2. Point spacing as small as possible The point spacing is the distance between the center points of the adjacent pixels of the LED screen. The smaller the point spacing, the more pixels per unit area, the higher the resolution, the closer the shooting distance can be, of course, the more expensive the price.

  At present, the domestic TV studio LED screen point spacing of more than 2.5-4 mm, to carefully study the signal source resolution and the relationship between point spacing, to achieve a consistent resolution, point to point display, so as to achieve the best results.

  3. Color Temperature Adjustment Studio using LED screen as the background, its color temperature should be consistent with the studio lighting color temperature, in order to get accurate color reproduction.

  Studio lighting According to the needs of the program, sometimes using 3200K low color temperature lamps, sometimes using 5600K high color temperature lamps, LED display should be adjusted to the corresponding color temperature, so as to obtain satisfactory results of the shooting.

  4. Ensure a good use of the environment LED screen life and stability are closely related to the working temperature. If the actual operating temperature exceeds the scope of the product specified, not only its life will be shortened, the product itself will be seriously damaged. In addition, the threat of dust should not be overlooked.

  Too much dust, will make the LED screen thermal stability or even leakage, serious will lead to burning, dust will also absorb moisture, thereby eroding electronic circuits, causing some difficult to troubleshoot the short-circuit problem, so pay attention to keep the studio clean. LED display screen does not sew, can make the picture more perfect; lower power consumption, less heat, energy saving and environmental protection; It has a good consistency, to ensure that the screen no difference display; the size of the box is small, so that the background screen can form a smooth shape; the color gamut coverage is higher than other display products, with better weak reflective characteristics and high reliability,

  Late operation and maintenance cost is low. Of course, with so many advantages of the LED screen must also be used well in order to make its advantage performance dripping. Therefore, the use of LED screen in TV programs, we have to choose the right LED screen, in-depth understanding of their characteristics, for different studio conditions, program forms and requirements to choose technology products as the background, so that these new technologies to maximize their advantages.
