The pixel—short for "picture element"—is the foundational unit of programmable color in digital imaging and display technology. Just as Lego bricks are stacked to build complex structures, pixels are arranged in a precise two-dimensional grid to form all images, videos, and text on digital screens, including TVs, smartphones, and computer monitors. As the smallest indivisible point of display, these tiny squares work together, blending seamlessly to our eyes to produce a continuous image.
Structure and Function
While appearing tiny to the naked eye, a pixel is typically square-shaped and behaves as a building block. In most display technologies, a pixel is composed of three sub-pixels—red, green, and blue (RGB). By varying the intensity of these three colors from 0% to 100%, each pixel can produce a wide spectrum of colors. When a transistor turns these sub-pixels on or off, it creates the image we see, with millions of these elements functioning in tandem.
Pixels, Resolution, and Image Quality
The total number of pixels in a screen or image defines its resolution. This is generally calculated by multiplying the horizontal pixels by the vertical pixels, such as High Definition (1920x1080) or 4K Ultra High-Definition (3840x2160).
