Speaking of led displays, everyone may be familiar with it. The development of led display production has also promoted the cultural civilization of the city. The large-screen LED display is highly respected and loved by people.

The birth of LED.

LED was born in 1923. When lossen.o.w studied semiconductor sic, he discovered that the impurity-doped p-n junction emits light after being energized, and thus developed the LED (light-emitting diode), but has been neglecting the application of LED since then. With the rapid development of the electronics industry, in the 1960s, display technology developed rapidly, and people studied various display technologies, such as pdp laser display plasma display panel, LED liquid crystal display, light-emitting diode LED and so on. Due to the maturity and perfection of semiconductor manufacturing and processing technologies, light-emitting diodes are increasingly occupying a dominant position in solid-state displays.

The advantages of LEDs.

The reason why LED is widely valued and developed rapidly is because it has many advantages. For example: high brightness, low working voltage, low power consumption, easy integration, simple drive, long life, impact resistance, stable performance, and extremely broad prospects for development. At present, it is moving towards higher brightness, higher weather resistance, luminous density, luminous uniformity and full color. With the development, people need large-screen display equipment, so there is a projector, but its brightness cannot be used under natural light, so there is an LED display (screen), which has the characteristics of large viewing angle, high brightness, and rich colors.
