Displays are electronic devices humans use to visually show and represent digital information. The primary function of a display is to act as an output device that facilitates the presentation of data, images, and volumes of input information for humans to understand. Displays makes this possible through the use of different connected input devices like computer monitors, television sets, head mounts, and many more. The earliest displays were made with Cathode Ray Tubes (CRT) which were mainly found in television sets. While CRT is no longer used for display devices, Liquid Crystal (LCD) and Light-emitting diode (LED) displays have become the norm as they offer higher resolutions and greater clarity. These modern displays have made led to higher quality performances and images in our workplaces and homes.
