Four precautions for studio LED display
With the introduction of indoor fine-pitch LED displays, LED displays are being used more and more in the radio and television industry. During the use of the studio LED display, the effect of the TV screen is very different due to factors such as the screen and the environment. Some of the pictures are bright, clear and stable from beginning to end; some are too small to see clearly in the distant view. This requires users to pay attention to the following issues in the selection and use of LED displays to ensure the best use effect.
1. The shooting distance should be appropriate
For LED displays with different dot pitches and different fill factors, the suitable shooting distances are different. 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.
2. The point spacing should be as small as possible
The dot pitch is the distance between the center points of adjacent pixels of the LED full-color display. The smaller the dot pitch, the more pixels per unit area, the higher the resolution, the closer the shooting distance can be, and of course the more expensive it is. At present, the dot pitch of LED displays used in domestic TV studios is mostly 6-8 mm. It is necessary to carefully study the relationship between the resolution of the signal source and the dot pitch, and strive to achieve consistent resolution and point-to-point display, so as to achieve best results.
3. Color temperature can be adjusted
When the studio uses the LED display 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.
4. Ensure a good use environment
The life and stability of the LED display are closely related to the operating 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 display 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 keeping the studio clean. .
The LED display screen is seamless, which can make the picture more perfect; it has lower power consumption, lower heat, energy saving and environmental protection; it has good consistency and can ensure the indiscriminate display of the picture; the size of the box is small, which is convenient for the composition of the background screen 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.
In practical applications, users can only maximize the use of LED displays by selecting appropriate LED displays, understanding their characteristics in depth, and selecting corresponding products and technologies for different studio conditions, program forms and requirements as the background.
