Full color LED advertising display application

Full-color LED displays are becoming more and more popular in TV studios. However, during the use of full-color LED displays, the effect of the TV picture varies greatly. Some pictures are bright, clear and stable from beginning to end; clear. This requires us to pay attention to several issues in the selection and use of full-color LED advertising displays:

1. The point spacing should be as small as possible

Dot pitch is the distance between the center points of adjacent pixels of a full-color LED 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 full-color LED displays used in domestic TV studios is 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. to achieve the best results.

2. The shooting distance should be appropriate

As mentioned earlier when talking about the dot pitch and fill factor, the suitable shooting distances are different for full-color LED displays with different dot pitches and different fill factors. 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.

3. The color temperature should be adjusted well

When the studio uses a full-color 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 that there is a good use environment

The life and stability of the full-color LED display are closely related to the working 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 full-color 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 maintaining the studio cleaning.

The full-color LED display has no seams, which can make the picture more perfect; the power consumption is lower, the heat is smaller, 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 background screen It forms a smooth shape; the color gamut coverage is higher than other display products; it has the advantages of better weak reflection characteristics, and has high operational reliability and low post-operation and maintenance costs.

Of course, the LED display screen with so many advantages must also be used well in order to make its advantages fully manifested. Therefore, when using LED displays in TV programs, we need to choose suitable full-color LED displays, understand their characteristics in depth, and select technical products as backgrounds for different studio conditions, program forms and requirements, so that these new technologies can maximize maximize its advantages.
