How many colors can be created in one individual LED? The answer could be “countless”.
In the LED era, we have the full flexibility that is difficult to imagine in the past. The semiconductor LED chip can “grow” in different chemical compositions that create different wavelengths – the colors.
With LED phosphor development, the combinations become numerous with the chips that much more colors are feasible in different spectral patterns.
In CIE 1931, which stands for the entire color range that human eyes can see, the chip+phosphor combination can achieve pixel-level accuracy to any point, no matter the light is for creating or rendering colors.
