LED screens,also known as light-emitting diode screens,have become an essential part of modern display technology.They are widely used in various applications, including televisions,computer monitors,billboards,and indoor/outdoor signage.In this article,we will explore the key components that make up an LED screen and their functions.
Section 1: LED PixelsThe fundamental building blocks of an LED screen are the LED pixels. These are tiny semiconductor chips that emit light when an electric current is applied. The pixels are typically composed of three LEDs: red (R), green (G), and blue (B), also known as RGB pixels. By varying the intensity of each color, millions of hues can be achieved.
Section 2: LED DriversLED drivers are responsible for controlling the power supplied to the LED pixels. They regulate the electrical current flowing through the LEDs and ensure their proper functioning. LED drivers convert the incoming power supply from AC (alternating current) to DC (direct current) and provide the required voltage and current levels to the pixels.
Section 3: LED ControllerThe LED controller is the central control unit of the LED screen. It receives input signals from various sources, such as computers or video players, and processes them to create the desired display output. The controller manages functions like color calibration, brightness control, refresh rate, and image/video processing.
Section 4: Power Supply Unit (PSU)The power supply unit is respons
