Прынцып візуалізацыі і аптымальны кут прагляду святлодыёднага экрана

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

Якасць выявы святлодыёднага экрана цесна звязана з наступнымі фактарамі: яркасць экрана дысплея, 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. Экран дысплея складаецца з мноства падсістэм, and we need to have a detailed understanding of each subsystem.

У яго ўваходзіць крыніца харчавання, video encoder and decoder codes, line drivers, digital signal processors (DSPs), і гэтак далей, which work closely together to generate video images. If you carefully observe the LED display screen, вы ўбачыце сотні асобных відэа панэляў. If you get closer, you will find that each panel contains 16X16 pixels. Анод кожнага святлодыёда электрычна падлучаны да выхаду святлодыёднага драйвера. Ultimately, гэтыя дзясяткі тысяч святлодыёдных драйвераў будуць кіраваць генерацыяй відэамалюнкаў праз сотні тысяч святлодыёдных шарыкаў.

The brightness of an LED display screen is not necessarily better the brighter it is. У некаторых асяроддзях, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display экран, 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 (Пастаяннага току), 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.
