The main part of a computer that people notice the most is the monitor, or the screen. Most of the newer computers use LCD screens or Liquid Crystal Display screens. LCD screen are becoming more and more popular because they are lighter, thinner and use up less energy than CRT screens, or Cathode Ray Tubes. LCD's are made up of multiple monochrome pixels, or color pixels, that are placed in front of a light reflector. LCD is also nice because it does not require a large amount of power to run. Every pixel that is inside of the LCD has one layer of molecules that are placed between transparent electrodes and filters. Light travels through the filters and then the pixels to create the wanted color and clarity.
Definition of pixel: the smallest possible place where an image or part of an image can be shown.
