Thin Film Transistor
Refers to technology employed in flat screen monitors, in which minute transistor elements control the alignment of liquid crystals in such a way that light is allowed to pass through or is blocked.
Within the TFT element, the total brightness and color reproduction are simultaneously controlled.
The light for every pixel passes through a color cell consisting of three color filters (red, green, blue), and every filter is equipped with a transistor that can be driven separately and controls the transmittance of light of every color element.
