LED electronic screens are increasingly used in large-scale events in TV studios and TV broadcasts. However, the effects of TV screens vary greatly during the use of LED electronic screens. Some of them are colorful, clear and stable from beginning to end; some are in perspective. The picture is small and can't be seen clearly. This requires us to pay attention to the following aspects in the selection and use of LED electronic screens:
1. The shooting distance should be appropriate
As mentioned in the previous discussion about point spacing and fill factor, LED screens with different dot pitches and different fill factors have different shooting distances. Taking an LED electronic screen 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 suitable for 4-10 meters, so that a good background image can be obtained when shooting a character. If the character is too close to the screen, the background will appear grainy when shooting close-ups, and it will also be prone to texture interference.
2. The spacing should be as small as possible
The dot pitch is the distance between the center points of adjacent pixels of the LED electronic 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 spacing of LED electronic screens used in domestic TV studios is mostly 6-8 mm. It is necessary to seriously study the relationship between the resolution of the signal source and the dot pitch, and strive to achieve consistent resolution and achieve point-to-point display. Effect.
3. Color temperature can be adjusted
When the studio uses the LED electronic screen as the background, its color temperature should be consistent with the color temperature of the studio, in order to get accurate color reproduction during shooting. The lighting of the studio is sometimes based on the demand of the program, sometimes using 3200K low color temperature lamps, sometimes using 5600K high color temperature lamps, and the LED electronic screen needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results.
4. Guarantee a good use environment
The life and stability of LED electronic screens are closely related to the operating temperature. If the actual working temperature exceeds the scope of use specified by the product, not only will its life be shortened, but the product itself will also be severely damaged. In addition, the threat of dust cannot be ignored. Too much dust will cause the thermal stability of the LED electronic screen to drop or even cause leakage. In severe cases, it will cause burns; the dust will absorb moisture, which will corrode the electronic circuit, causing some short-circuit problems that are difficult to check, so pay attention to keep the studio clean. .
In the use of led electronic screens in TV programs, we have to choose the right LED electronic screen, to understand their characteristics, to select technical products as background in different studio conditions, program forms and requirements, so that these new technologies can be maximized. Its advantages.
