Shandong LED Display Screen : Simply put Electronic Display Screen It is composed of several combinable display units (unit display boards or unit display cabinets) forming the screen body, plus a set of appropriate controllers (main control board or control system). Therefore, various specifications of display boards (or unit cabinets) combined with controllers using different control technologies can form many types of LED display screens to meet different environments and display requirements.

LED electronic display screens are composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixel points arranged evenly. Different materials can be used to manufacture LED pixel points of different colors. Currently, red, green, and yellow are widely used. The development of blue and pure green LEDs has reached a practical stage.

LED display screens can show changing numbers, text, graphics, and images; they can be used not only indoors but also outdoors, possessing advantages that projectors, video walls, and LCD screens cannot match. The widespread attention and rapid development of LEDs are inseparable from their inherent advantages. These advantages can be summarized as:

High brightness, low operating voltage, low power consumption, miniaturization, long lifespan, impact resistance, and stable performance. The development prospects of LEDs are extremely broad, moving towards higher brightness, better weather resistance, higher luminous density, better luminous uniformity, reliability, and full color.

Electronic Display Screen Composition:

Metal Structural Frame

Indoor screens generally use aluminum alloy (angle aluminum or aluminum square tube) to form the inner frame, carrying display boards and various circuit boards as well as switching power supplies. The outer frame uses tea-colored aluminum alloy square tubes, or aluminum alloy wrapped stainless steel, or integrated sheet metal. Outdoor screen frames are generally made of angle steel or I-beams depending on the screen size and load capacity, and the outer frame can be decorated with aluminum-plastic panels.

Display Unit
This is the main part of the display screen, composed of luminous materials and driving circuits. Indoor screens are various specifications of unit display boards, while outdoor screens are unit cabinets.

Scan Control Board

The function of this circuit board is data buffering, generating various scan signals and duty cycle grayscale control signals.

Switching Power Supply

Converts 220V AC power into various DC voltages to supply different circuits.

Twisted Pair Transmission Cable

Display data and various control signals generated by the main controller are transmitted to the screen body via twisted pair cables.

Main Controller

Buffers the input RGB digital video signal, performs grayscale transformation, reorganizes it, and generates various control signals.

       Shandong LED Display Screen : In addition to the basic functions of a computer display card, it also outputs digital RGB signals and horizontal/vertical blanking signals to the main controller. Multimedia functions include the above and can convert input analog video signals into digital RGB signals (i.e., video capture).
