Precautions in the application of full-color LED advertising display screen

point spacing is the distance between the center points of adjacent pixels of full-color LED display screen. The smaller the point spacing, the more pixels per unit area, the higher the resolution, and the closer the shooting distance. Of course, the more expensive it is. At present, the point spacing of full-color LED display screen used in domestic TV studios is mostly 6-8 mm. It is necessary to carefully study the relationship between the resolution of signal source and point spacing, and strive to achieve consistent resolution and point-to-point display, so as to achieve the best effect

2. The shooting distance should be appropriate

as mentioned in the previous discussion on spacing and filling factor, the appropriate shooting distance is different for full-color LED displays with different point spacing and filling factor. 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 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

3. The color temperature should be well adjusted

for example, the experimental machine is divided into hydraulic experimental machine and electronic experimental machine according to the experimental force in the experiment. When the studio uses the full-color LED display 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 reappearance in the shooting. According to the program requirements, sometimes 3200K low color temperature lamps and sometimes 5600k high color temperature lamps are used for the studio lighting, and the LED display needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results

4. Ensure good universality and good use environment

the service life and stability of full-color LED display are closely related to the working temperature. If the actual operating 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, said Sebasti á n d í AZ, the project leader. In addition, the threat of dust should not be ignored. Too much dust will reduce the thermal stability of full-color LED display and even cause electric leakage, which will lead to burning in serious cases; Dust Xinjiang Zhonghe has become a core backbone enterprise in the field of new materials in China. It will also absorb moisture, which will corrode electronic circuits and cause some short-circuit problems that are difficult to check. Therefore, it is necessary to keep the studio clean

full color LED display screen has no seams, which can make the picture more perfect; Lower power consumption, less heat, energy saving and environmental protection; It has good consistency and can ensure the non differential display of the picture; Small box size, easy 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 display with so many advantages must also be used well in order to fully display its advantages. Therefore, when using LED display in TV programs, we should select appropriate full-color LED display, deeply understand their characteristics, and select technical products as the background according to different studio conditions, program forms and requirements, so as to maximize the advantages of these new technologies
