In the HD led screen, the ratio of the number of lines lit at the same time to the number of lines in the entire area is called the scanning mode. The scan is also divided into 1/2 scan, 1/4 scan, 1/8 scan, 1/16 scan, and other driving methods. That is to say, the drive mode of the display screen is different, so the settings of the receiving card are also different. If the receiving card was originally used on a 1/4 scan screen and is now used on a static screen, then the display on the display will be lit every 4 lines. Generally, the receiving card can be set. After connecting the sending card, display screen, computer, and other main components, you can enter the relevant software on the computer to set. So here we will first introduce the scanning mode and principle of LED small-pitch display.

HD led screen display principle

The display resolution of the LED screen (the so-called spatial resolution) is closely related to the distance or pitch between the pixels in the LED video display;

LED screen maximum brightness: Dynamic brightness range is understood as the number of brightness levels the screen can support (sometimes also called emission or energy resolution);

LED screen frame rate is usually a measure of how often a video source can feed an entire frame of new data display, the rate at which frames change per second (fps) (sometimes referred to as temporal resolution);

The number of times (in Hertz) the LED screen refresh rate is when the second display hardware draws data or refreshes the frame (also known as time resolution);

LED screen spectral resolution: Color images distinguish different spectrums of light. Multispectral images resolve even better wavelengths than required for different spectrums or to reproduce colors. The word determines how many spectral components create an image; color uniformity across the screen; white balance and fine-tuning possibilities;

Led screen linear brightness sense – subjective image quality, the quality determines the human eye to distinguish adjacent brightness levels between dark and bright parts of the screen;

LED screen image comparison; image quality depends on viewing angle. In addition to image quality, it is important to consider some key operating parameters of LED video displays.

The above briefly describes the principle of high-definition small-pitch LED screen display; mature software and comprehensive control system, enabling the system to expand and build LED and LCD video display network and remote control through the Internet through the built-in information security subsystem; horizontal electromagnetic radiation electromagnetic interference ( EMI) form from the screen.
