A) LED-backlight Liquid Crystal Display
B) Field Emission Display
C) Surface-Conduction Electron-Emitter Display
D) Rear Projection Liquid Crystal Display
Correct Answer: C
Solution :
[c] A surface-conduction electron-emitter display (SED) is a display technology for flat panel displays developed by a number of companies. SEDs use nano scopic- scale electron emitters to energize coloured phosphors and produce an image. In a general sense, an SED consists of a matrix of tiny cathode ray tubes, each "tube" forming a single sub-pixel on the screen, grouped in threes to form red-green-blue (RGB) pixels. SEDs combine the advantages of CRTs, namely their high contrast ratios, wide viewing angles and very fast response times, with the packaging advantages of LCD and other flat panel displays. They also use much less power than an LCD television of the same size.
