In liquid crystal displays (LCDs), use is made of linear polarisers, familiar to most as the glass in polarising sunglasses. If you 'cross' two polarisers (i.e. arrange them at 90 degrees to each other) then light does not pass through. This is the basis of the LCD, but between the cross polars the liquid crystals are arranged with a 'twist' Liquid crystal display - Liquid crystal display - Supertwisted nematic displays: It was discovered in the early 1980s that increasing the twist angle of a liquid crystal cell to about 180-270° (with 240° being fairly common) allows a much larger number of pixel rows to be used, with a consequent increase in the complexity of images that can be displayed Liquid Crystals: The Story Behind the Technology Did you know that liquid crystals were discovered by a botanist studying carrots? Liquid crystals, most commonly known today for their presence in liquid crystal displays (LCDs), have a molecular makeup somewhere in between a solid and a liquid. Unlike a solid, their molecules are not ordered, but unlike a liquid they do follow some structure Liquid Crystal Displays (LCDs) The first working liquid crystal display (LCD) was demonstrated at RCA in 1968. In the following year, James Fergason of Kent State University (OH) discovered the twisted nematic field effect which allowed a much higher-quality display and led to the first commercial LCD wristwatch in 1979

Liquid crystal display and organic light-emitting diode

  1. A liquid crystal display is a special thin flat panel that can let light go through it, or can block the light. (Unlike an LED it does not produce its own light). The panel is made up of several blocks, and each block can be in any shape. Each block is filled with liquid crystals that can be made clear or solid, by changing the electric current to that block
  2. Liquid crystal display technology works by blocking light. Specifically, an LCD is made of two pieces of polarized glass (also called substrate) that contain a liquid crystal material between them. A backlight creates light that passes through the first substrate. At the same time, electrical currents cause the liquid crystal molecules to align.
  3. Liquid crystal displays show data using the principle of 'light blocking'. They produce an image using a backlight. An LCD is made up of a large number of pixels. The resolution depends on the number of pixels. It is available in various backlight colors like green, yellow, blue. Mostly we use the standard 16×2 Liquid crystal display
  4. Liquid Crystal Display. LCD1602 is a character type liquid crystal display, which can display 32 (16*2) characters at the same time. As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller.

When current is applied to this special kind of crystal, it turns opaque blocking the backlight that lives behind the screen. As a result that particular area will become dark compared to other LCDs use voltage applied to a field of microscopic liquid crystals to change the crystal's orientation, which in turn changes the polarization of the liquid crystal which creates light or dark pixels on the display. These pixels are arranged to create characters or graphic images

Liquid crystal phases are useful in displays because they interact with light and electric fields like crystals, but they can move (flow) like liquids, making it possible to use electric fields to change their effect on light.
