Download Solution PDFMechanism of LCD:
- The LCD consists of a large number of pixels, or picture elements, consisting of liquid crystal molecules held between two sets of transparent electrodes.
- The liquid crystals react in predictable ways when the electrical charge running between those electrodes is changed — meaning they twist and move in ways that let different amounts (and colors) of light through the crystals.
- When compared to the other type of flat-panel display (plasma), LCDs tend to be found on the smaller size of the spectrum.
