LED display screen is a kind of diode (LED chip) made of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), indium (In) compounds by controlling the display mode of semiconductor light emitting diodes. When electrons and holes are combined, they can emit visible light, so they can be used to make light emitting diodes. It can be used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide phosphor diode emits red light, gallium phosphide diode emits green light, silicon carbide diode emits yellow light, indium gallium nitrogen diode emits blue light, and white light and yellow light.

In recent years, the online live broadcast industry has become more and more popular. Many businesses will choose to install a large live broadcast screen in the live broadcast room for live broadcast of goods or live broadcast display. Here, many users do not know whether to choose the splicing screen or LED screen, so I will make a brief analysis for you

According to the level of supply voltage, LED drivers can be divided into three categories: one is powered by batteries, mainly used for portable electronic products, driving low-power and medium-power white LEDs; the other is power supply greater than 5, powered by regulated power supply or battery Power supply, such as step-down and buck-boost DC converters; the third is to directly supply power from mains (110V or 220V) or corresponding high-voltage direct current (such as 40~400V), mainly used for camel-driven high-power White LEDs, such as step-down DC/DC converters.

We all know that the LED display belongs to customized products, which is not the same as the general electronic consumer products. It is a simple business process, but involves the implementation of a whole set of system planning plans. From pre-sales planning including other related work to after-sales construction equipment and protection, businesses are required to complete many hours.

The terms "LED engine" and "LED module" are often used interchangeably in the lighting industry, but they refer to slightly different components with distinct functions.

LED Display Power Supply: LED displays usually require constant current power supplies. LEDs are sensitive to changes in current, so a constant current source is needed to ensure uniform brightness across the display. Ordinary Power Supply: Ordinary power supplies typically provide a constant voltage output.
