Optical Properties of Liquid Crystals and LCD Displays Research Paper

Optical Properties of Liquid Crystals and LCD Displays - Research Paper ExampleThe pellucid crystals are used in various consumer audiovisual devices among other office gadgets such as calculators, cellphone phones, digital cameras, watches, stereos, clocks, laptop computers and other personal organizers. The LCDs are also applied as instruments information viewing in automobiles speedometers, clocks and navigation aids. Nevertheless, there are a number of competing display technologies such as the light emitting diodes (LEDs), the plasma displays (PDs), and the organic light-emitting diodes.Liquid crystal displays incorporate the unique properties of current materials, nematic, selected smectic and cholesteric liquids. In certain liquid phases, the materials exhibit some electro-optic effects attributed to crystals. A typical liquid crystal display contains twain electrodes or polarizer. A liquid crystal film material plugs the space surrounded by the two electrodes (Gu 2010, p. 6). methamphetamine hydrochloride fibers are used as spacers that keep the thickness of the liquid crystals uniform within a pad of 5 to 10 (Koide 2014, p. 86). The plates are also known as the polarizers, which are usually orientated at 900 to one another. The twisted phase commonly serves to reorient light that passes through the first plate, which consequently allows the contagion of the light through the second polarizer. When an electric theater is applied to the liquid crystal layer, the molecular axes dress parallel to the electric field and untwist. In such a state, light is not oriented fashioning the polarized light from the first polarizer, which leads to loss of transparency with a further increase in voltage. This electric field property can be applied in making a pixel switch between the opaque and the transparent on command.
