Prensip Imaging ak ang gade optimal nan ekran ki ap dirije ekspozisyon

The imaging of full-color LED display screens is generally achieved through files, videyo, imaj, 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?

Bon jan kalite a foto nan ekran ekspozisyon dirije se pre relasyon ak faktè sa yo: klète ekran ekspozisyon an, 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. Ekran ekspozisyon an konpoze de anpil subsistèm, and we need to have a detailed understanding of each subsystem.

Li gen ladan ekipman pou pouvwa, video encoder and decoder codes, line drivers, digital signal processors (DSPs), ak sou sa, which work closely together to generate video images. If you carefully observe the LED display screen, ou pral wè dè santèn de panno videyo endividyèl elèv yo. If you get closer, you will find that each panel contains 16X16 pixels. Anod nan chak dirije elektrik konekte ak pwodiksyon yon chofè ki ap dirije. Ultimately, sa yo dè dizèn de milye de chofè ki ap dirije pral kontwole jenerasyon an nan imaj videyo nan dè santèn de milye de pèl ki ap dirije.

The brightness of an LED display screen is not necessarily better the brighter it is. Nan kèk anviwònman, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display ekran, 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 (DC), 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.
