When the outdoor LED display enters the room, its brightness needs to be appropriately reduced to meet the needs of indoor display; but when the outdoor LED display brightness drops to 500cd/㎡ or even lower, or even below 600cd/㎡, it has begun to appear more obvious The phenomenon of gray-scale loss, and with the further decrease in brightness, gray-scale loss becomes more and more serious (generally speaking, the higher the gray level, the richer the color displayed on the display screen, the more delicate and fuller the picture, the gray is the display color The decisive factor of the quantity, for the outdoor LED display industry, the high gray scale screen brings the beauty closer to the real color). And when the brightness drops below 200cd/㎡, most displays have a great loss of grayscale, and the picture quality almost reaches the level of "eye-catching", and a lot of picture details are missing.
(The picture on the left shows the serious lack of picture detail after the grayscale is lost) The picture of the outdoor LED display is composed of countless LED lamp beads, so the fineness of the picture depends on the dot pitch (or density) of the lamp beads, per unit area The more the number of LED lamp beads, the higher the screen fineness of the LED screen, and the richer the display of screen details. Based on this, the current outdoor LED display is moving in the direction of small-pitch, mini-LED display.
