The stage background led electronic large screen space is huge

The stage background led electronic large screen has a huge space, and the led electronic large screen has a good communication effect, especially the realistic scene on the stage and the high degree of color reproduction, which creates a good atmosphere for the scene environment. Many companies engaged in wedding services have installed LED electronic large screens to expand more business and enrich the different needs of customers. Our customers have estimated that buying a large LED electronic screen and renting it 15 times can recover the cost of the investment. Led electronic large screens are becoming more and more mature, and are widely used in stage background display, showing a broader market space.

With good visual expression and flexible installation methods, led electronic large screens are popular in various concerts, cultural evenings, opening ceremonies and other cultural and sports activities, and have become a necessary tool for setting and color effects in large-scale performance venues. Seven parameters of led electronic large screen: 1. White balance effect White balance effect is one of the important indicators of led electronic large screen. In terms of color science, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. If there is a slight deviation in the actual ratio, there will be a deviation in white balance. Generally, it is necessary to pay attention to whether the white is blue or yellowish. green phenomenon.

The quality of the white balance is mainly determined by the LED chip, and the LED chip also affects the reproduction of the color. 2. Whether there are color blocks or not? Color blocks refer to the lack of color on the small-area LED electronic screen; the main reason is to control the IC and power supply, and the quality of the control circuit wiring. 3. Whether there is mosaic or dead spot Mosaic refers to the small squares that are always bright or dark on the LED electronic large screen, which is the phenomenon of module necrosis. The main reasons are: ①The quality of the connectors used in the LED electronic large screen However, there are protrusions or depressions; ②The LED light is not adjusted; ③The sealant process is unqualified.

The dead point refers to a single point that is often black on the LED electronic large screen. The number of dead points is mainly determined by the quality of the LED chip. 4. Brightness and viewing angle The brightness of the indoor full-color LED electronic large screen must be above 800cd/m2, and the brightness of the outdoor full-color LED electronic large screen must be above 1500 cd/m2 to ensure the normal display of the LED electronic large screen. Otherwise, the displayed image will be hard to see because the brightness is too low. The level of brightness is mainly determined by the quality of the LED tube core.

The size of the viewing angle directly determines the size of the viewing area of ​​the LED electronic large screen, so the bigger the better. The size of the viewing angle is mainly determined by the led chip. 5. Flatness The surface flatness of the LED electronic large screen should be within 0≤a≤1mm to ensure that the displayed image will not be distorted, and local protrusions or recesses will cause dead angles in the viewing angle of the display.

The quality of flatness is mainly determined by ① production process and materials; ② on-site steel engineering construction; ③ installation and construction quality of the display installation team. 6. Color reducibility The color reducibility refers to the reducibility of the LED electronic large screen to the color, that is, the color displayed on the LED electronic large screen must be highly consistent with the color of the playback source, so as to ensure the realism of the image. 7. The appearance of the display screen should be flat, the pixel lamp beads should form a straight line horizontally and vertically, the flatness of the front should be less than 1mm, and the outer edge should be balanced. If it is an outdoor large LED screen, waterproof treatment should be done well.
