Product features<\/strong><\/p>\n

\u25c6 Large-format uniform lighting<\/p>\n

\u25c6 Effective luminous surface accounted for a high proportion<\/p>\n

\u25c6 Can achieve different color mixing scheme<\/p>\n

\u25c6 High degree of integration, to avoid switching back and forth between different color light sources<\/p>\n

The blue light source has a short wavelength and weak penetration, and the blue channel value in the GBWY four-color mixed backlight is raised, and the value of other channels is lowered, highlighting the contours of the transparent colloid.<\/span><\/td>\nThe product is frosted material, black products are illuminated, the overall brightness is low, and the channel value of the four colors can be adjusted to the highest, increasing the brightness of the screen for easy detection.<\/span><\/td>\n<\/tr>\n
