This isn't exactly a new technology, but it has yet to be commercialized.
What you are describing is a field-emission display; the "cones" are electron
emitters (i.e., "Spindt cathodes") which are used to drive conventional
CRT phosphors located on the upper glass. There are a large number of
emitters per pixel, giving reasonably uniform characteristics and reducing
problems with single-emitter defects.
