Thin-film transistors.

The individual image dots in an LCD flat screen are controlled by means of thin-film transistors Each image dot (or pixel) consists of three of these transistors. For each image dot, these control whether red, green or blue light is allowed to pass.


A thin-film transistor consists of a large number of thin layers that are applied and structured during a multilayer coating process. Up to four of the layers are produced from molybdenum. Consequently, our material determines whether, and how brightly, any given area of the screen is illuminated. The sharpness of the final image and the speed with which it can be built on screen depends on the purity of our molybdenum.
