The specifications of the LED display mainly include the following aspects:   Pixel pitch: The pixel pitch is the physical distance between the pixels of the LED display, usually expressed in millimeters (mm). Smaller pixel pitch (for example: P2.5, P3, P4 ) means denser pixels and clearer image display.   Brightness: The brightness of the LED display refers to the luminous intensity of the LED light-emitting diode, usually expressed in nits. The higher brightness makes the display clearly visible in bright outdoor environments.   Contrast Ratio: Contrast refers to the brightness ratio between the brightest and darkest parts of the display. A higher contrast ratio improves image detail and color expression.   Refresh Rate: The refresh rate refers to the number of times the display refreshes the image per second, expressed in Hertz (Hz). A higher refresh rate reduces image flicker and motion blur.   Color Saturation: Color Saturation refers to the degree to which led display screen can present true colors. Higher color saturation can make the image more colorful and vivid.   Viewing Angle: The viewing angle refers to the range in which the display still maintains image quality and brightness when viewed from the side. Larger viewing angles allow more people to view the led display from different angles without distortion or dimming.   Advantage: – High brightness and clarity, suitable for outdoor bright environment. – Larger size and flexible shape to attract people’s attention. – Durable and adaptable to various weather conditions. – It can be controlled remotely and updated in real time to facilitate content publishing.   Shortcoming: – Higher initial investment, involving equipment and installation costs. – High energy consumption, requiring a lot of power consumption. – Some display screens have limited viewing angles, so you need to choose a suitable viewing position. – Some low-end products may have image quality and reliability issues.   It is necessary to choose the appropriate LED display specifications according to actual needs and budget, and weigh its advantages and disadvantages.
