What is meaning of LCD ?

Liquid crystal display is composed of several layers which include two polarized panel filters and electrodes

LCD technology is used for displaying the image in notebook or some other electronic devices like mini computers

Light is projected from a lens on a layer of liquid crystal.

An LCD is either made up of an active matrix display grid or a passive display grid.

Most of the Smartphone’s with LCD display technology uses active matrix display, but some of the older displays still make use of the passive display grid designs.

The liquid has a unique advantage of having low power consumption than the LED or cathode ray tube.

Liquid crystal display screen works on the principle of blocking light rather than emitting light.

High-resolution color displays,

such as modern LCD computer monitors

televisions, use an active-matrix structure.

A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor,

allowing each column line to access one pixel.

It has a mirror (A) in back, which makes it reflective

Then, we add a piece of glass (B) with a polarizing film on the bottom side,

An LCD is a display of information on a screen, which uses liquid crystals that become visible when electricity is passed through them. LCD is an abbreviation for 'liquid crystal display'.

hiiii

A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D).

lowest common denominator

LCDs allow displays to be much thinner than cathode ray tube (CRT) technology.

Like light-emitting diode (LED) and gas-plasma technologies

LCD (liquid crystal display) is the technology used for displays in notebook and other smaller computers

liquid-crystal display

a device for alphanumeric displays, as on digital watches, using a pattern of tiny, sealed capsules which contain a transparent liquid crystal that becomes opaque when an electric field is applied to it: the contrast between transparent and opaque areas forms the image of a number, letter, etc.

Twisted Nematic (TN) Twisted Nematic LCDs are the most commonly manufactured and used types of monitors across a wide range of industries.
