What influence the viewing angle of led display

One key factor of the led display quality is the viewing angle. Here we will discuss what influence the viewing angle of led display.

As well known that when watching the led display from a small or big viewing angle, the brightness and color performance is different. For some led display screens, when watching it from a small viewing angle, it has a very good white balance; but when watching it from a big viewing angle, it performs not that good. The influence is not only in the color, but also the brightness.

In essential, it is determined by the LEDs. The LEDs for the led screens have their own viewing angle, so firstly when the RGB LEDs compose one pixel, the viewing angle of all the LEDs in one pixel should be accordant, and when all the pixels compose one led display, the viewing angle of all the pixels should be accordant. The accordance of the LEDs will directly determine the white balance of the led screens, watching from different viewing angle. To achieve the perfect accordance, the LED encapsulation lens and other materials should be designed strictly. Only the good led encapsulation companies could achieve that, with the high technology level, advanced production and test equipments.

So as the led display screen manufacturer in China, we don't think we'd get into the field of LED encapsulation, which requires very long period of experiences. After all, the division of labor is very important to produce high quality finished products. No matter which industry, no manufacturer could do all the process and materials, only the division labor of one supply chain's high efficiency could make it perfect.
