Principio de imágenes y ángulo de visión óptimo de la pantalla LED de visualización

La imagen de las pantallas LED a todo color generalmente se logra a través de archivos, videos, imagenes, and text on the computer. Send to the sending card through the graphics card for transcoding processing. Then go to the receiving card to drive imaging. So how can we achieve the best display effect when choosing an LED display screen?

La calidad de imagen de la pantalla LED está estrechamente relacionada con los siguientes factores: el brillo de la pantalla de visualización, the width of the picture, and the optimal visual distance for installation. Only when each indicator meets the needs of the current usage environment, then the display effect is the best. La pantalla de visualización se compone de muchos subsistemas, and we need to have a detailed understanding of each subsystem.

Incluye fuente de alimentacion, video encoder and decoder codes, line drivers, digital signal processors (DSPs), etcétera, which work closely together to generate video images. If you carefully observe the LED display screen, Verás cientos de paneles de video individuales.. If you get closer, you will find that each panel contains 16X16 pixels. El ánodo de cada LED está conectado eléctricamente a la salida de un controlador LED. Ultimately, estas decenas de miles de controladores LED controlarán la generación de imágenes de video a través de cientos de miles de cuentas LED.

The brightness of an LED display screen is not necessarily better the brighter it is. En algunos ambientes, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display pantalla, it is necessary to match the most suitable brightness according to the usage scenario or adjust it automatically through a driver. This is the only way to provide satisfactory LED display quality without harming the audience’s eyes.

Most high-end LED drivers provide designers with multiple methods to control the LED current in their systems. These drivers have some features that help reduce LED brightness, such as point correction (corriente continua), pulse width modulation (PWM) dimming, and global brightness control (BC). Although these features all provide the same basic function of adjusting LED brightness, their usage is different. Understanding and utilizing these features correctly is the key to having the best quality video.

Regarding the wide viewing angle and optimal viewing distance of LED display screens, it is necessary to conduct standard measurement and calculation of the usage scenario before installation, calculate the required viewing angle and viewing distance, and then match them according to this requirement. This can ensure that the product meets the specific needs of the usage scenario and presents the most exciting and high-quality images to the audience.
