Digital screens

RGB digital screens are a feature of TV’s, computers, phones, monitors and projectors.

  • A digital screen (or digital display) is an output device for the presentation of information in a visual form.
  • An RGB digital screen adjusts the colour values of the red, green and blue pixels within each addressable component of the screen to produce an image.
  • Fully saturated hues (colours) rely on the intensity (brightness) of each group of pixels.
  • Tints of any hue are produced by increasing the colour value sent to each RGB component in step with one another, which increases the brightness of the output without favouring a particular hue.
  • Shades are produced by decreasing the value sent to each RGB component so dimming the device without affecting the colour of images on the screen.
