Liquid-crystal display (LCD) Over View

LCD Display History:

Liquid-crystal display (LCD) was invented in 1964 at RCA Laboratories in Princeton, NJ. In 1970, twisted-nematic (TN) mode of operation was discovered, which gave LCD the first commercial success. The LCD manufacturers supplied small-size displays to portable products such as digital watches and pocket calculators. In 1988, Sharp Corporation demonstrated a 14-in. active-matrix full-color full-motion display using a TFT (thin-film-transistor) array. Observing this, Japan launched a true LCD industry. Large-size displays were first supplied to personal computers and then to television receivers. In the second half of 1990s, the industry has moved to Korea and Taiwan.

Industrial Display Systems:

Industrial Display Systems provide a wide range of reliable displays from 5.7″ to 55″ including LCD displays, touch screen panels, outdoor displays and digital signage displays, and a series of industrial monitors including open frame monitors and panel mount monitors, which work perfectly with embedded boards and systems to fulfill various application needs.

LCD Display Size:

On 2D displays, such as computer monitors and TVs, the display size (or viewable image size or VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels.

LCD Monitors:

Liquid crystal displays are flat panel monitors which modify a white backlight by creating a barrier of millions of liquid crystals which can adjust which color is ultimately displayed to the end user.

Application of LCD (liquid crystal display):

  1. The LCDs are commonly used in all the digital wrist watches for displaying time.
  2. The LCD (liquid crystal display) is used in aircraft cockpit displays.
  3. It is used for displaying images used in digital cameras.
  4. It is used in instruments panel where all the lab instruments uses LCD screens for display.
  5. It is used as a display screen in calculators.
  6. The television is main applications of LCD.
  7. Mostly the computer monitor is made up of LCDs.
  8. The LCDs are used in mobile screens.
