Topic: backlit projector screen

In recent years, the characteristics of high-definition display, high refresh rate, seamless splicing, good heat dissipation system, convenient and flexible disassembly and assembly, energy saving and environmental protection of small-pitch LED display screens have been well known by the majority of industry users, but, going further, when it comes to small The specific process technology of pitch LED screens is rarely known to the general public, "only knowing one but not the other". The lack o...

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 LED 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 v...
