Four tips for the most popular use of studio LED s

The "four essentials" formula for using the LED screen in the studio

it was reported not long ago that lyade assisted Zhejiang satellite TV to build the first full led background studio. This trend also shows that led screens are becoming more and more popular in TV studios. However, in the process of using LED screens, the effect of TV pictures varies greatly, and some pictures are bright, clear and stable from beginning to end; There are some pictures that cannot be seen clearly in the long view. This requires us to pay attention to several problems in the selection and use of LED screen

1. The shooting distance should be appropriate

as mentioned above, the appropriate shooting distance is different for LED screens with different dot spacing and different filling coefficient. Taking the LED display screen with a dot spacing of 4.25 mm and a filling factor of 60% as an example, the distance between the photographed person and the screen is more appropriate at 4-10 meters, so that a better background picture can be obtained when shooting people. If the characters are too close to the screen, the background will appear grainy when shooting close range, and it is easy to produce texture interference

2. The point spacing should be as small as possible

the point spacing is the distance between the center points of adjacent pixels of the LED screen. The smaller the dot spacing, the more pixels per unit area, the higher the resolution, the closer the shooting distance, and of course, the more expensive it is. At present, domestic TV studios use 7. Experimental speed: the dot spacing of LED screens of 0.001~500mm/min is mostly 6-8 mm. We should carefully study the relationship between the resolution and dot spacing of signal sources to better serve the rapidly growing customers, and strive to achieve the same resolution and achieve point-to-point display, so as to achieve the best effect

3. The color temperature should be adjusted well

when the studio uses the LED screen as the background, its color temperature should be consistent with the color temperature of the lights in the studio, so as to get accurate color reproduction in shooting. According to the program requirements, sometimes 3200K low color temperature lamps and lanterns are used in the studio, sometimes 5600k high color temperature lamps and lanterns are used, and the LED display screen needs to be adjusted to the corresponding color temperature, so as to obtain a satisfactory shooting effect

4. Ensure a good operating environment

the life and stability of LED screen are closely related to the working temperature. If the actual working temperature exceeds the specified service range of the product, not only its service life will be shortened, but also the product itself will 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 burning in serious cases; Dust will also absorb moisture, which will corrode electronic circuits and cause some short-circuit problems that are not easy to check, so pay attention to keep the studio clean

led screen has no seams, which can make the picture more perfect; Lower power consumption, less heat, energy saving and environmental protection; In addition, it has good consistency, which can ensure the undifferentiated 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 that of other display products; It has the advantages of better weak reflection characteristics, high operation reliability and low operation and maintenance cost in the later stage

of course, the LED screen with so many advantages must also be used well in order to show its advantages incisively and vividly. Therefore, the obvious answer in TV programs is to use LED screens in the former. We should choose 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
