Liquid crystals with low molecular weight can be mixed with high molecular weight polymers, followed by phase-separation to form a kind of spongy matrix filled with LC droplets. An external electric field can align the LC to match its index with that of the polymer matrix, switching that cell from a milky (scattering) state to a clear ...
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]

Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays. [56] Extremely bulky and heavy construction in comparison to other display technologies. Large displays would be unsuitable for wall mounting. New models are no longer produced.
OFF state. In the OFF state, i.e., when no electrical field is applied, the nematic liquid crystal molecules form a twisted configuration (aka helical structure or helix) between the two glass plates, G in the figure, which are separated by several spacers and coated with transparent electrodes, E 1 and E 2.
Liquid crystals have a natural relaxed state. When a voltage is applied they rearrange themselves to block certain light waves.If left with the same voltage for an extended period of time (e.g. displaying a pointer or a taskbar in one place, or showing a picture for an extended period of time), the liquid crystals can develop a tendency to stay in one position.
A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display. It is by far the most widely produced and sold type of television display.
Liquid crystals find wide use in liquid crystal displays, which rely on the optical properties of certain liquid crystalline substances in the presence or absence of an electric field. In a typical device, a liquid crystal layer (typically 4 μm thick) sits between two polarizers that are crossed (oriented at 90° to one another).
