Important common sense during the selection of outdoor LED full-color screens

Outdoor LED full-color screens have a wide range of uses. Many users can install a LED full-color screen at the entrance of their own building to advertise themselves to attract customers' attention. However, for the first installation, there are many technical issues that need to be understood. First, the outdoor LED full-color screen The color screen is suitable for long-distance viewing. Secondly, waterproof, dustproof and constant temperature are also very important. Faced with many specifications, it is difficult to know which specification is suitable for you. The picture effect of each factory's outdoor full-color LED screen is very different during the use process. Some pictures are bright, clear and stable from the beginning to the end, and some pictures are small and hard to see in the distant view. This requires us to select and use the outdoor LED full-color screen. A few points should be paid attention to. The viewing distance is directly related to the dot pitch: for outdoor LED full-color screens with different dot pitches and different fill factors, the suitable shooting distance is different.

Taking an LED full-color screen with a dot pitch of 4 mm and a fill factor of 60% as an example, the distance between the human body and the screen is 4-10 meters, so that a better background image can be obtained when shooting the human body. If the human body is too close to the full-color LED screen, the background will appear grainy when shooting close-up shots, and it is also prone to moire interference. Temperature, humidity, and dust protection also need to be done well: the life and stability of LED full-color screens are closely related to the working temperature. If the actual working temperature exceeds the specified range of use of the product, not only its life will be shortened, but the product itself will also be damaged. severely damaged.

In addition, the threat of dust cannot be ignored. Too much dust will reduce the thermal stability of the LED full-color screen and even cause leakage. In severe cases, it will cause burnout; the dust will also absorb water, which will corrode the electronic circuit and cause some short-circuit problems that are not easy to troubleshoot, so pay attention to keeping the studio clean . The color temperature can be adjusted adaptively: when the studio uses the LED full-color screen as the background, its color temperature should be consistent with the color temperature of the lighting in the studio, so as to obtain accurate color reproduction during shooting.

According to the requirements of the program, the lighting in the studio sometimes uses 3200K low color temperature lamps, and sometimes uses 5600K high color temperature lamps, and the LED full-color screen needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting effects. The greater the density, the better the display effect: the dot pitch is the distance between the center points of adjacent pixels of the LED full-color screen. The smaller the dot pitch, the more pixels per unit area, the higher the resolution, and the shorter the shooting distance can be. The closer it is, the more expensive it is, of course. At present, the dot spacing of LED full-color screens used in China is mostly 4-8 mm. It is necessary to carefully study the relationship between the resolution of the signal source and the dot spacing, and strive to achieve consistent resolution and achieve point-to-point display, so as to achieve the best effect. .

Of course, the outdoor LED full-color screen with so many advantages must be used well in order to make its advantages fully manifest. Therefore, when screening outdoor LED full-color screens, we need to choose the appropriate LED full-color screen specifications, understand their characteristics in depth, and choose technical products as the background for different studio conditions, program formats and requirements, so that these new technologies can maximize play to its strengths. The LED full-color 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 indiscriminate display of the picture; the size of the cabinet is small, which is convenient for the smooth composition of the background screen Shape; the color gamut coverage is higher than other display products; it has the advantages of better weak reflection characteristics, the LED full-color display has high operational reliability, and the post-operation and maintenance costs are also very low.
