The powerful giant "Black Dragon Series" is to meet the needs of customers for indoor full-color high-end display effects, and to optimize the composition of indoor full-color products, to stabilize the strong giant color in the LED display industry, and to launch a powerful giant indoor Full color top grade products. Throughout the "Black Dragon Series" products, the dot pitch, driver chip and module kit are slightly fine-tuned, but the only constant is that the whole series adopts the main military quality, stable and reliable--Lanke Black Crystal SMD Surface Sticker III One black light! Such a consistent choice stems from the pursuit of quality and the high standards of display, and is also in line with the historical process of high-end indoor small spacing from white to black!
"White" has passed <br> <br> early chip LED lamp is not high due to its shiny level, designers use a white plastic bowl holder enhanced focusing reflective effect, thereby indirectly enhance the brightness level chip. Although the white light improves the brightness level, when the black color is gray, the light-emitting diode color (white) also participates in the color mixing of the electronic display screen, thereby generating color distortion (cannot express black, gray, deep). Green, etc.). And because the LED display screen used in the outdoor commercial display, because the viewing distance is far, the brightness of the display screen is placed first, so that the loss of color can be accepted to compensate for the brightness. But now, the advancement of LED packaging technology has led to an increase in the brightness of the light, and the high-density and small-pitch LED display technology has become increasingly mature. The LED lamp beads have no need to be white to achieve satisfactory results. At the same time, in order to meet people's requirements for image fidelity and improve the contrast of LED display screens, Lanke Electronics, a domestic LED display packaging factory, has achieved the ultimate black light process and developed the blackest black grade in the market. light.
The "black" era is fully flowering. The display performance of the LED display screen determines the performance of the display by the quality of the fidelity performance, and the quality of the fidelity is mainly determined by the two hard indicators of contrast and color value expression. Contrast refers to the measurement of different brightness levels between the brightest white and the darkest black in a dark and dark area of ​​an image. For example, an LED display has a brightness of 500 cd/m2 in a full white screen state and a full black screen brightness of 0.5. Cd/m2, so the contrast of the screen is 1000:1; the larger the difference range is, the larger the contrast is, and the smaller the difference range is, the smaller the contrast is. When the contrast ratio of 120:1 is reached, vivid and rich colors can be easily displayed. When the contrast ratio is as high as 300:1, the colors of each order can be supported. Therefore, the contrast has a great influence on the visual effect. Generally speaking, the contrast is larger, the image is more clear and conspicuous, and the color is more vivid and bright; while the contrast is small, the whole picture is grayed out.
The high contrast ratio greatly improves the sharpness, detail performance, and gray level performance of the image. In some text and image display applications with large contrast between black and white, high-contrast LED displays have unique advantages in black-and-white contrast, sharpness, and integrity; in video and dynamic picture display, due to light and dark conversion in dynamic images. It's faster, so the higher the contrast, the easier it is for the human eye to distinguish between such conversions. Therefore, in the display surface of the display screen made of black light, an image with uniform color, vitality and deeper color can be presented.
In addition to the high contrast, the black light adds a higher quality non-reflective performance. The PPA bracket in the black LED lamp bead is black plastic. Because the black absorbs light and does not reflect light, the light is directly converted into heat energy on the black object, so even when there is stray light, the black PPA bracket will All absorption, no reflection of stray light and thus reduce interference, make the color more realistic, without the phenomenon of cross-color, tailing and mutual interference of colors, making the color more pure, clear and more realistic. Through the atomization treatment technology of the LED lamp bead surface, the light is diffusely reflected, which further reduces the stray light interference, so that the display effect of the LED display screen is clearer and is not affected by the brightness of the external environment.
Black lights era leader <br> <br> because black light show many advantages in the field of high-end small pitch, only to strong giant color "Black Dragon" series consistently choose Lanke black crystal SMD SMD 3 black The lamp is used as the material for the lamp of the product. The era of white lights has passed. Under the double demand of small spacing and high definition, this era must belong to the powerful giant "Black Dragon Series".
