Beijing Jianhong Weiye Advertising Co., Ltd. is a high-tech enterprise specializing in the production, sales, design, production and installation of LED billboards, LED display screens, LED electronic light boxes and other products, For example, the brightness of most of the ur red tubes used for automobile tail lamps is only half of the original brightness after ten to dozens of hours of lighting.
the brightness decay cycle has a great relationship with the material technology of LED production.
generally, if the economic conditions permit, the quaternion led with slow brightness decay should be selected.

color matching, color matching and color matching White balance:
2 white is the mixture of red, green and blue according to the brightness ratio.
when the brightness of green is 69%, the brightness of red is 21%, and the brightness of blue is 10%, the brightness of green is 69%, However, the chromaticity coordinates of red, green and blue LED can not achieve the full color effect due to the process and other reasons.
controlling the brightness of the primary color including the deviation of the brightness of the primary color to get white light is called color matching.

3 before color matching for full-color LED display.
in order to achieve the best brightness and the lowest cost, We should try our best to choose the LED device with three primary colors whose luminous intensity is about 3:6:1 to form the pixel.
the white balance requires that the three primary colors should still be pure white under the same gray value.

4 primary colors refer to the basic colors that can synthesize various colors.
the primary colors in the color light are red, green and blue.
the following figure is the spectrum table, and the three vertices in the table are the ideal primary color wavelengths.
the three primary colors in the table are red, green and blueIf there is a deviation in the primary color,
the area that can synthesize color will be reduced, and the triangle in the spectrum table will be reduced. From the visual point of view, the color will not only have deviation, but also reduce the richness.

5 the red, green and blue light lines emitted by LED can be roughly divided into purplish red, pure red, orange red, orange, orange yellow, yellow green, pure green, emerald green, blue-green, pure blue, red, red, yellow, yellow, green, pure green, green, red, green, green, blue, red, green, green, red, green, green, green, green, green Blue and purple, etc.
orange red, yellow green and blue and purple are much cheaper than pure red, pure green and pure blue.
among the three primary colors, green is the most important.
because green occupies 69% of the brightness of white, And in the center of the color horizontal arrangement table.
therefore, when weighing the relationship between color purity and price.
green is the key consideration.
