What are the factors affecting the quality of LED stage screen?
Nowadays, LED stage screen with its own colorful, varied patterns and many other advantages, can be effectively catered to in the stage application of people for the requirements of choreography applications, to create a good stage atmosphere, will be fantastic, science and technology, the market, fashion and other concepts to show out, thus making the LED stage screen has become an important part of the choreography. However, LED stage screen quality is often affected by a number of factors, then you know the impact ofLED stage screenWhat are the factors of high and low quality? The following Vishay technology editorial for your introduction:
Factors that affect the high quality of LED stage screen are as follows:
1. Brightness
LED brightness is an important determinant of the brightness of the LED stage screen. the higher the LED brightness, the greater the margin of the current used, which is good for saving power consumption and maintaining the stability of the LED. the LED has a different angle value, in the case of the chip brightness has been determined, the smaller the angle, the brighter the LED, but the smaller the angle of view of the display. Generally should choose 100 degrees of LED to ensure that the LED stage screen has a sufficient viewing angle.
2. Loss of efficiency
As the LED stage screen consists of tens of thousands or even hundreds of thousands of groups of red, green and blue LED pixels, the failure of any color LED will affect the overall visual effect of the display.
3、Leveling
LED stage screen surface flatness should be within ± 1mm to ensure that the display image is not distorted, localized convex or concave will lead to the display of the visual angle of the dead center. Good or bad flatness is mainly determined by the production process, LED stage screen installation process technicians also need to carefully and carefully observe the installation to ensure flatness.
4. Pixel Pitch
Pixel pitch on the LED stage screen clarity of the impact is very obvious, the smaller the pixel pitch, the more delicate its screen display. Pixel pitch reduction must have mature technology as the core support, from the current trend, pixel pitch reduction is the inevitable choice of the market.
5. Gray scale level
Gray level refers to the LED stage screen singleBrightness of the base color brightness from dark to bright to distinguish between the number of brightness levels, the higher the grayscale level, the richer the color, the more colorful; on the contrary, the display of a single color, simple changes. Grayscale level of improvement, can greatly enhance the color depth, making the image color display levels geometrically increased.
6、Attenuation Characteristics
Red, green and blue LEDs have the characteristic of brightness attenuation with the increase of working time, the advantages and disadvantages of LED chips, the good and bad of auxiliary materials and the level of encapsulation process determines the attenuation speed of LEDs. Generally speaking, 1000 hours, 20 mA room temperature light test, red LED attenuation should be less than 10%, blue, green LED attenuation should be less than 15%. red, green, blue attenuation of the consistency of the LED stage screen later white balance has a great impact on the LED stage screen, which in turn affects the LED stage screen display fidelity.
7, the use of stability and security
LED stage screen in operation, stability and safety is particularly important, the box design is very important, the components of the thermal conversion of the temperature increases, which will lead to a decline in the quality of the image screen. Therefore, good ventilation and heat dissipation design is an indispensable and important indicator of the box design. On the one hand, its circuit protection, on the other hand, safety, etc., as well as dustproof, waterproof role. At the same time, supporting the power supply can not just look at the low price and ignore its performance and quality, in different temperature conditions of the power supply, the stability of its work, the output voltage and load capacity will be different, because it serves as an after-sales protection role, so the safety of the LED stage screen directly affects the quality of the picture.
In summary, we can see that the factors affecting the quality of the LED stage screen include brightness, failure rate, flatness, pixel pitch, gray level, attenuation characteristics, stability and safety and so on. Of course, in addition to these aspects, there are some small details, we must also pay attention to, so that we can better help you buy a high-quality LED stage screen.
