Knowledge for White balance and white field color temperature selection for fine pitch led display

Fine pitch led display

According to the visual characteristics of the human eye, people like images with different color temperatures under different environmental illuminances. According to this feature, when the environmental brightness changes, we can not only automatically adjust the brightness of the display, but also the color temperature of the display can automatically change to meet The requirements of human visual characteristics.

The relationship between white field color temperature and RGB brightness is as follows: According to the principle of colorimetry, the color matching equation in the "RGB" and "XYZ" color counting systems is:

[F]=R(R)+G(G)+B(B)= X(X)+Y(Y)+Z(Z)

x, y, z are chromaticity coordinates, where:

x=X/X+Y+Z

y=Y/X+Y+Z

z=Z/X+Y+Z

After the chromaticity coordinates of each primary color LED are accurately measured by the advanced color analyzer CS-100 and the white field color temperature is selected, the brightness ratio of the three primary colors is obtained through the brightness equation, so that the display screen can be used in various environments Achieve the most comfortable white field color temperature for human eyes.
