LED display as the core equipment of modern advertising, information dissemination and entertainment activities, has been widely used in various occasions. When selecting and using LED displays, it is important to understand their specifications. This article will analyze the main specifications of the LED display in detail to help readers better understand and choose the LED display that suits their needs.

First, screen size and resolution

Screen size is usually expressed in length x width format in inches or millimeters. Resolution refers to the number of pixels on the screen, expressed as the number of horizontal pixels × the number of vertical pixels. The higher the resolution, the finer the display quality. The selection of screen size and resolution needs to be determined according to the actual application scenario, such as outdoor billboards, indoor meeting rooms or sports venues.

Second, pixel spacing and point distance

Pixel pitch refers to the center distance between adjacent pixel points, usually in millimeters (mm). Point distance refers to the actual physical size occupied by pixels, and is related to pixel spacing. The smaller the pixel spacing, the more delicate the display, suitable for close viewing. On the contrary, the larger the pixel spacing, suitable for remote viewing. Therefore, when selecting an LED display, it is necessary to determine the appropriate pixel spacing according to the viewing distance and scene needs.

Third, brightness and contrast

Brightness refers to the intensity of light emitted by the screen and is measured in candela per square meter (cd/m²). Contrast is the ratio of brightness between the brightest and darkest parts of the screen. Brightness and contrast directly affect the display effect. High-brightness LED displays are suitable for outdoor or intense light environments, while high-contrast displays can present richer colors and clearer images.

Fourth, viewing Angle

Viewing Angle refers to the maximum Angle from which the viewer can clearly see the content of the screen when viewing from the front of the screen. In general, the larger the horizontal and vertical viewing angles, the better the audience will look at the screen in different positions. Therefore, when selecting the LED display, it is necessary to consider the location and number of the audience to ensure that the viewing Angle of the screen meets the needs.

Five, refresh rate and gray level

Refresh rate refers to the number of times a screen is updated per second, usually in Hertz (Hz). The high refresh rate LED display can reduce the picture drag and blur, improve the display effect of dynamic images. Gray level refers to the number of levels of brightness displayed on the screen, the higher the gray level, the richer the display color. Generally speaking, the higher the gray level, the better the display effect.

6. Control mode and signal interface

Control mode refers to the driving mode of the LED display, including synchronous control and asynchronous control. Synchronous control needs to be connected with a computer or other equipment to achieve real-time display; Asynchronous control has independent data storage and processing capabilities, and can operate independently from the computer. Signal ports are used to connect the display screen to external devices, such as HDMI, VGA, and DVI. Selecting the appropriate control mode and signal interface can ensure the compatibility and stability of the LED display and external devices.

To sum up, understanding the specifications of the LED display is crucial to choosing a display that suits your needs. In practical applications, it is necessary to choose the most appropriate LED display according to the scene, viewing distance, display content and other factors.
