TFT-LCD Technology

TFT-LCD consists of two thin glass substrates and polarizer films between which a layer of liquid crystals is deposited and behind which a light source called a backlight unit is mounted. The front glass substrate is fitted with a color filter, while the back glass substrate, also called a TFT array, has a thin film of transistors, or TFT, formed on its surface. The liquid crystals are normally aligned to allow the polarized light from the backlight unit to pass through the two glass panels to form a picture element, or pixel. When voltage is applied to the transistors on the TFT array, the liquid crystals change their alignment and alter the amount of light that passes through them. Meanwhile, the color filter on the front glass substrate gives each pixel its own color. The combination of these pixels in different colors and levels of brightness forms the image on the panel.
