Liquid Crystal Display (LCD) is a flat-panel display which uses the light-modulating properties of the liquid crystals that are combined with the polarizers. Liquid crystals do not produce/emit light directly instead of that it uses a backlight or a reflector to produce the images in colour or monochrome. But, What is the full form of LCD?

LCD full form is Liquid Crystal Display. LCDis used in a wide range of applications like LCD Televisions, computer monitors, aircraft cockpit displays and many more. The small LCD screen is also used in portable consumer devices like digital cameras, watches, calculators, smartphones etc.

What is the history of LCD?

The origin and complex history of Liquid Crystal Display (LCD) were described by the Joseph A. Castellano in Liquid Gold: The Story of Liquid Crystal Display (LCD) and the Creation of an Industry. Another report which tells about the origin and history of LCD from a different point of view until 1991 was published by Hiroshi Kawamoto that is available at the IEEE History Center.

If you want to know about a descriptive of Swiss contributions to Liquid Crystal Display (LCD) development which is written by Peter J. Wild, and that can be found at the Engineering and Technology History Wiki.

What are the specifications of LCD?

The specifications of the LCD are as follows: –

  1. Resolution: – The resolution of a Liquid Crystal Display (LCD) is expressed by the number of rows and columns of pixels present in it. The pixel can be like 1024×768 and there are other pixels also. Every pixel is composed of 3 sub-pixels i.e. a red, a green and a blue. This is one of the best few features of LCD performance which remained the same among the different designs.
  2. Spatial Performance: – For a PC monitor or any other display which is being viewed from a very close range, resolutions are often expressed in terms of the dot pitch or pixels per inch, that is consistent with the printing industry. The Density of displays varies from application to application. If we talk about televisions then, televisions have a low density for a long-distance view and portable devices which are having a high density for close-range detail. 
  3.  Colour Performance: – There are multiple terms that can describe the different aspects of colour performance of a Liquid Crystal Display (LCD) display. Colour Gamut is the range of colours that can be displayed and colour depth, which describes the fineness with which the colour range is divided. If we talk about colour gamut then, it is a relatively straight forward feature, but it is rarely discussed in marketing materials except at the professional levels.

What are the advantages of LCD?

The advantages of Liquid Crystal Display (LCD) are as follows: –

  • LCD’s are very compact, thin and light especially when we compare them with CRT displays.
  • Liquid Crystal Display consumes low power consumption.
  • Liquid Crystal Display (LCD) uses no geometric distortion.
  • Liquid Crystal Display  shows sharp images with no bleeding or smearing when they are operated at the native resolution.
  • Liquid Crystal Display (LCD) can be made of any size or shape.
  • LCD’s are unaffected by any kind of magnetic fields, including the earth.

What are the disadvantages of LCD?

If there are advantages of anything then, there are disadvantages also. So, let us see the disadvantages of Liquid Crystal Display (LCD): –

  • Liquid Crystal Display (LCD) have limited viewing angle in some order or cheaper monitors, causing colour, saturation etc.
  • There is some uneven backlighting in some monitors especially toward the edges which can cause brightness distortion and other disease or infection.
  • The Black level of LCD’s may not be as dark as required as it is because of the individual liquid crystals that cannot completely block all the backlight from passing through.
  • There can be a loss of contrast in high-temperature environments.

Now, let us see some amazing facts related to Liquid Crystal Display (LCD): –

  1. Liquid Crystal Display (LCD) has over 6 million pixels.
  2. LED displays are actually Liquid Crystal Display (LCD).
  3. LCD’s consumes 25% less power than the CRT’s.
  4. Liquid Pixels contains 3 Sub-Pixels. They are defined above also.
  5. Over 200 Million of LCD TV’s are sold annually.
