Flat-panel displays are electronic viewing technologies that show content in a range of entertainment, consumer electronics, personal computer and mobile devices as well as many types of medical, transportation and industrial equipment.
They are much lighter and thinner than traditional cathode ray tube television sets and video displays and are usually less than 10 centimetres thick. Flat-panel displays have almost completely replaced old CRT displays.
A flat panel display, like all LCD displays, is made primarily of two pieces of glass with liquid crystal material between them. Varying electrical current is applied to the liquid crystal material to rearrange the pixels to display the appropriate images.
Reactive SiO2 is used in this technology.
