Зургийн дэлгэцийн дэлгэц, оновчтой үзэх өнцөг

Бүрэн өнгөт LED дэлгэцийн дэлгэцийн дэлгэцийг ерөнхийдөө файлуудаар дамжуулан хэрэгжүүлдэг, видео, зураг, 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?

LED дэлгэцийн дэлгэцийн чанарын чанар нь дараахь хүчин зүйлүүдтэй нягт холбоотой юм: дэлгэцийн дэлгэцийн тод байдал, 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. Дэлгэцийн дэлгэц нь олон дэд системээс бүрдэнэ, and we need to have a detailed understanding of each subsystem.

Үүнд цахилгаан хангамж орно, video encoder and decoder codes, line drivers, digital signal processors (DSPs), гэх мэт, which work closely together to generate video images. If you carefully observe the LED display screen, та хэдэн зуун видео самбарыг харах болно. If you get closer, you will find that each panel contains 16X16 pixels. LED бүрийн анод нь LED драйверын гаралттай цахилгаанаар холбогддог. Ultimately, эдгээр хэдэн арван мянган LED драйверууд хэдэн зуун мянган LED бөмбөлгүүдийгээр дамжуулан видео дүрс үүсгэх процессыг хянах болно.

The brightness of an LED display screen is not necessarily better the brighter it is. Зарим орчинд, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display дэлгэц, 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. Эдгээр драйверууд нь LED гэрлийг багасгахад туслах зарим онцлог шинж чанартай байдаг, цэг засах гэх мэт (DC), импульсийн өргөн модуляци (ХБХ) dimming, and global brightness control (МЭӨ). 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.
