Color displays

Color displays work by combining tiny individually controlled light sources—such as pixels—that emit red, green, and blue light. By varying the intensity of these three colors in each pixel, the display creates a wide range of colors that the human eye perceives as smooth and vibrant images. This process relies on additive color mixing: adding more of each primary hue produces different colors. Modern screens use technologies like LCD, LED, or OLED to precisely control these light emissions, enabling detailed, colorful visuals for everything from smartphones to large monitors.
