1. How does an ecran LED exterior work?

The working principle of the ecran LED exterior is similar to that of an ordinary LED display, and its work is based on the light-emitting principle of a light-emitting diode (LED). Here is a brief overview of how ecran LED exteriors work:

  • LED lighting principle:

LED (Light Emitting Diode) is a semiconductor device. When current passes through it, the PN junction inside it emits light. The color of LED light depends on the type and chemical structure of its semiconductor material.

In the ecran LED exterior, a large number of LED lamp beads of different colors (such as red, green, and blue) are used. By controlling the brightness and color combination of these LED lamp beads, various colors and images can be displayed.

  • Control System:

ecran LED exteriors are usually composed of multiple LED modules; each module contains multiple pixels, and each pixel is composed of LED lamp beads in three colors: red, green, and blue.

The control system is the core part of the LED display screen. It is responsible for receiving external signals (such as video, images text, etc.) and converting them into a signal format that the LED display screen can recognize. The control system usually includes the main controller, signal processor, driver chip, and other components.

The main controller is the core of the entire system, responsible for receiving and analyzing external signals, and then sending control signals to the driver chip based on the analysis results. The driver chip is responsible for driving the brightness and color changes of the LED lamp beads according to the control signal.

  • Display content transfer:

To display content on an LED display, you first need to convert the images, videos, or text that need to be displayed into a signal format that the LED display can recognize. This is usually done through specialized software or equipment.
