Overview
A pixel is the smallest addressable physical element of a raster image or display device, arranged in a two-dimensional grid to form digital images. With a history dating back to the early days of television, pixels have become a fundamental concept in digital imaging. The term 'pixel' has been used in various U.S. patents since 1911, and today, pixels are used in a wide range of applications, from digital displays to medical imaging, with companies like [[nvidia|NVIDIA]] and [[amd|AMD]] developing advanced pixel technologies.
