Five key technologies for the quality of LED display

1. Brightness and viewing angle

The brightness of the display mainly depends on the luminous intensity of the LED and the density of the LED. In recent years, new technologies in 75mm Foldable LED Mesh Curtain substrate, epitaxy, chip and packaging have emerged in an endless stream, especially the stability and maturity of indium tin oxide (ITO) current spreading layer technology and process, which has greatly improved the luminous intensity of LED. At present, when the horizontal viewing angle is 110 degrees and the vertical viewing angle is 50 degrees, the luminous intensity of the international first-class brand low-power LEDs has reached 4000mcd for green tubes, 1500mcd for red tubes, and 1000mcd for blue tubes. When the pixel pitch is 20mm, the display brightness can reach more than 10000nit. The display can work 24/7 in any environment. Read more
