Pixel

A pixel is the smallest addressable element in a digital image that can be uniquely processed and is defined by its spatial coordinates and colour values.

  • A pixel, or a picture element, is a physical point in a digital image and the smallest addressable element of a display device.
  • During editing, a pixel is the smallest controllable element of a digital image.
  • Many digital displays, including LCD screens, contain LEDs arranged in a grid pattern and emit light when an electrical current is passed through them, allowing them to display different colours and brightness levels.
  • OLED displays use a different technology that uses organic compounds that emit light when an electrical current is passed through them.
  • The RGB colour model is commonly used for still images displayed on digital screens, such as computer monitors and televisions.
  • In the RGB colour model, each pixel is composed of three sub-pixels that control the red, green, and blue colour channels.
  • By varying the light emitted by an LED, every pixel can display a wide range of colours and shades, allowing for the creation of highly detailed and vibrant images on-screen.
