LCD monitor

Liquid crystal displays (LCDs) are gaining in popularity for use as display deveices for computer monitors. An LCD displays images by adjusting light transmittance ratios of liquid crystal cells by respectively supplying data signals according to image information to the liquid crystal cells arranged as a matrix configuration. LCD monitors offer many advantages, over other display technologies, such as low power consumption and small size. An LCD monitor is light and can be made thin and an image is displayed usually clearly without distortion, so that its application is being extended for wide coverage in desktop and portable computers including laptop computers. Typical LCD displays are formed from liquid crystals sandwiched between two optical polarizers. An LCD device includes a color filter substrate, an array substrate, and a liquid crystal material layer formed between the color filter and array substrates. A thin film transistor (TFT) is commonly used as a switching device of the LCD monitor, wherein the TFT includes one of amorphous or polycrystalline silicon as a channel layer.
