A pixel, short for “picture element,” is the smallest unit of a digital image or display that can be individually controlled and assigned a color. Pixels are arranged in a grid to form images on screens such as smartphones, TVs, and monitors. Each pixel typically contains red, green, and blue subpixels that combine to produce a wide range of colors through varying intensities. The clarity and detail of a display are determined by its resolution, which is the number of pixels across the screen. Higher pixel counts result in sharper, more detailed images, making pixels fundamental to modern digital visual technology.
