1, perspective
LED display angle depends on the LED lamp beads perspective.
2, brightness
LED brightness is an important determinant of the brightness of the display.
3, failure rate
As the full color display by tens of thousands or even hundreds of thousands of groups of red, green and blue LED composed of three pixels, any color LED failure will affect the overall visual effects of the display.
4, anti-static ability
LED is a semiconductor device, sensitive to static electricity, easily lead to electrostatic failure, so the anti-static capacity of the display life is essential.
5, life expectancy
LED device theoretical life of 100,000 hours, much larger than the LED display other parts of the working life, so as long as the LED device quality assurance, working current is appropriate, PCB cooling design is reasonable, the display production process rigorous, LED device will be the entire screen One of the most durable parts of the machine.
6, attenuation characteristics
LED display after a long period of time will appear after the decline in brightness and display color inconsistencies, mainly due to the brightness of LED devices caused by attenuation.
