Αρχή απεικόνισης και βέλτιστη γωνία προβολής της οθόνης οθόνης LED

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

Η ποιότητα εικόνας της οθόνης LED σχετίζεται στενά με τους ακόλουθους παράγοντες: τη φωτεινότητα της οθόνης, 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. Η οθόνη εμφάνισης αποτελείται από πολλά υποσυστήματα, and we need to have a detailed understanding of each subsystem.

Περιλαμβάνει τροφοδοσία, video encoder and decoder codes, line drivers, digital signal processors (DSPs), και ούτω καθεξής, which work closely together to generate video images. If you carefully observe the LED display screen, θα δείτε εκατοντάδες μεμονωμένα πάνελ βίντεο. If you get closer, you will find that each panel contains 16X16 pixels. Η άνοδος κάθε LED συνδέεται ηλεκτρικά με την έξοδο ενός οδηγού LED. Ultimately, Αυτές οι δεκάδες χιλιάδες οδηγοί LED θα ελέγχουν τη δημιουργία εικόνων βίντεο μέσω εκατοντάδων χιλιάδων σφαιριδίων LED.

The brightness of an LED display screen is not necessarily better the brighter it is. Σε ορισμένα περιβάλλοντα, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display οθόνη, 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.
