down-converters‚ millimeter wave generation‚ ferroelectric thin film devise‚ organic semiconductors‚ and electro-optic effects in molecular and liquid crystals. In 1964 he discovered several new electro-optic effects in liquid crystals. This led to the first working liquid crystal displays based on what Heilmeier called dynamic scattering mode or DSM. DSM allows liquid crystals to scatter light when a voltage is applied. George Heilmeier’s discovery is essentially used by everyone in the modern world. LCD screens

There are two types of monitors on the market today‚ CRT and LCD. CRT Monitors or Cathode Ray Tube uses a tube similar to old television screens. CRT Monitors contain an electric charged storage capacitor‚ deadly if touched. LCD Monitors or Liquid Crystal Display uses TFT technology or Active Matrix. There are several specifications to conceder when choosing a monitor. Such as Screen Size‚ Contrast Ratio‚ Refresh Rate Interlacing (CRT)‚ Response Time (LCD)‚ Resolution‚ and much more.

Monitor (computer)‚ in computer science‚ device connected to a computer that displays information on a screen. Modern computer monitors can display a wide variety of information‚ including text‚ icons (pictures representing commands)‚ photographs‚ computer rendered graphics‚ video‚ and animation. Most computer monitors use a cathode-ray tube (CRT) as the display device. A CRT is a glass tube that is narrow at one end and opens to a flat screen at the other end. The CRTs used for monitors have rectangular
