TFD (Thin Film Diode)

Thin film diode (TFD) generally refers to any diode produced using thin-film technology.

TFD is a kind of Liquid crystal display (LCD) technology. It is an active-matrix technology which means that a diode is situated next to each pixel making it possible for the pixels to be turned on and off individually. This allows a quicker response time and more contrast than passive-matrix technologies.

TFD takes the excellent picture quality and the fast response of TFT displays and combines them with the low power consumption and cost of the STN ones.
