Thin Film Transistor. At the present time, LCDs are mainly actuated using this technology. For each pixel a dedicated transistor is placed on one of the glass plates of the display. Each transistor can be separately controlled, - hence each pixel as well. With this technology, higher contrasts (about 200:1) and above all, far less inert response times than those of the older DSTN technology can be accomplished, which was unable to display fast movements due to the rather long persistence times of the individual pixels.
