led display brightness and viewing angle
LED display brightness depending on light intensity and LED density. In recent years, new technology LED substrate, epitaxial, chip and packaging and other aspects of endless, especially indium tin oxide (ITO) current spreading layer technology and process stability and maturity, the LED luminous intensity has been greatly improved. Currently, world-class brand of small power LED in the horizontal viewing angle of 110 degrees vertical viewing angle of 50 degrees, the luminous intensity of the green tube has reached 4000mcd, red tube of 1500mcd, blue tube up 1000mcd.
In a pixel pitch of 20mm, the display brightness can reach 10000nit more. Display can work around the clock in any environment. When it comes to the display perspective, there is a phenomenon worthy of our consideration: LED display, especially outdoor display, people's viewing angle is basically from the bottom, while the product shape to the existing LED display view, there half of the flux disappeared into the vast sky.
