A pixel (short for "picture element") is the smallest, fundamental unit of a programmable digital image or display. These tiny squares or dots arranged in a grid emit red, green, and blue (RGB) light to form all colors and images on screens, such as TVs, phones, and monitors. Higher pixel counts mean higher resolution, sharper, and more detailed images.

Key Details About Pixels:
Structure: Each pixel is composed of sub-pixels that emit red, green, and blue light. By varying the intensity of these colors, the pixel displays a specific, single color.
Building Block: Pixels are the, "building blocks" of digital images, similar to Legos, where millions of them work together to form a coherent picture.
Resolution & Quality: Resolution is the total number of pixels on a screen or in an image (e.g.,
), meaning more pixels create better, sharper, and more detailed imagery.
