What should be noticed during the selection and use of LED screens?
The effect of TV screens varies greatly during the use of LED screens. Some of the screens are bright, clear and stable from start to finish. This requires us to pay attention to several issues in the selection and use of LED screens.
1. Adjust the color temperature.
When a studio uses an LED screen as its background, its color temperature should be consistent with the color temperature of the lights in the studio in order to obtain accurate color reproduction during shooting. According to the needs of the program, the studio lighting sometimes uses 3200K low color temperature lamps and sometimes 5600K high color temperature lamps. The LED display needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results.
2. Dot spacing should be as small as possible.
Dot pitch is the distance between the center points of adjacent pixels of the LED screen. 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 the LED screens 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 for consistent resolution to achieve point-to-point display, so as to achieve the most Good effect.
3. The shooting distance should be appropriate.
As mentioned earlier when talking about dot pitch and fill factor, the proper shooting distance for LED screens with different dot pitch and different fill factor is 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 is more suitable between 4-10 meters, so that when photographing people, an excellent background picture can be obtained. If the person is too close to the screen, the background will appear grainy when shooting close-ups, and it is also prone to moiré interference.
4. Ensure a good use environment.
The life and stability of the LED screen 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 severely 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 cause burnout. In addition, dust will also absorb moisture, which will corrode electronic circuits and cause some short-circuit problems that are not easy to check. Therefore, we must keep the studio clean.
The LED 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, which can ensure the display of the screen without difference; the size of the cabinet is small, which is convenient for the background screen to form a smooth shape ; Color gamut coverage is higher than other display products; Has the advantage of better weak reflection characteristics, and high operational reliability, low operation and maintenance costs in the future.
Of course, an LED screen with so many advantages must also be used well to make its advantages manifest to the fullest. Therefore, when using LED screens in TV programs, we must choose the appropriate LED screens, understand their characteristics, and select technology products as backgrounds based on different studio conditions, program formats and requirements, so that these new technologies can maximize their use Advantage.
