Black leds Naked Eye 3D LED Display

Early chips due to the brightness is not high, so engineers will make the plastic bracket into a white bowl used to enhance the focus of the reflective, to ensure that the brightness of the chip is not high to achieve a brighter effect. But the white light has its drawbacks, to show black, gray, his light-emitting diode color (white) is also involved in the electronic display to express the color, which produces a color distortion (can not show black, gray, dark green, etc.). Engineers to loss of color expression to make up for the lack of chip brightness. 

Previously led display screen is mostly used in Outdoor Led Display, because the viewing distance is far, so the display brightness has high requirements, can accept the loss of color to make up for the brightness of the practice. However, now, in the LED luminous brightness is getting bigger and bigger, high-density small pitch led display is getting more and more mature, LED lamp beads have not need to be made white to achieve satisfactory results. At the same time, in order to meet the requirements of people on the image fidelity, improve the contrast of led display screen is more widely required.

Contrast on the visual effect of the impact is very critical, generally speaking, the greater the contrast, the clearer the image is eye-catching, the more vivid and colorful; while the contrast is small, it will make the whole picture is gray. High contrast for image clarity, detail performance, gray level performance are very helpful. In some text display and video display with large black and white contrast, high contrast led display has advantages in black and white contrast, clarity and integrity. Contrast for dynamic video display effect to be more influential, due to the dynamic image of dark and light conversion is relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.

Black leds Naked Eye 3D Led Display not only brings high contrast, but also brings another even better performance, which is non-reflective. Because the black LED lamp beads in the PPA bracket for the black, because the black is not reflective light, that is, there is no reflective ability, so the light shines on the black object is converted into other energy (such as heat), so even when there is stray light, the black PPA bracket will absorb all of them, and no longer reflect the stray light, which reduces the interference of the stray light, so that the color is more realistic, there will be no Stringing colors, trailing and the phenomenon of mutual interference of each color, so that the color is more pure, clear, higher fidelity.

Therefore, at present, more and more Indoor Led Display and Outdoor LED Display in the choice of lamp bead material are used in the Black leds program.
