Technical parameters of waterproof full-color display screen for outdoor columns in Yandu P4

　　Yandu P4 outdoor full box waterproof display screen, LED is a current emitting device. When current flows through it, it emits light, and when no current flows through it, it does not emit light. The magnitude of the current flowing through it determines its luminous intensity. The different materials used in light-emitting diodes determine the color and intensity of the light emitted by the current flowing through them. Each color of LED is divided into three types based on its brightness: ordinary bright, high bright, and ultra-high brightness.

　　The quality of the chip directly determines the quality of the display screen. In order to ensure the quality of the display screen, Furui Lai Electronics has stable performance and quality chips.

　　LED screen is an array layout formed by arranging each pixel vertically and horizontally at a certain point spacing. Each light emitting diode in the LED screen has a corresponding brightness control circuit. The brightness and darkness of each light emitting diode in the LED screen form the desired image or text on the LED screen.

　　The entire display screen of Furui Lai Electronics is composed of unit modules, control circuits, switch power supplies, and outer frame steel structures, which are sturdy, durable, and aesthetically pleasing
