Application of optical tricolor

Display technology: advanced display technologies such as liquid crystal display (LCD) and organic light emitting diode (OLED) are based on the principle of three primary colors. By adjusting the intensity and proportion of red, green and blue light, various colors and images can be displayed.

Projection technology: the projector also works according to the principle of three primary colors. By irradiating red, green and blue light on the projection screen, a color image can be presented.

Color photography: in color photography, the principle of three primary colors is also widely used. By reasonably adjusting the exposure of red, green and blue, you can take photos with bright colors and distinct layers.
