Nanofluidic Fluorescent Display (NFD)
Based on Daniel Kleppner's "Inhibited spontaneous emission"
paper in 1981, we propose a new type of fluorescent flat panel
display technique, which has the advantages of no limit of the
screen size, fast response, energy economy and low cost. This
display technique is based on controlling the fluorescent emission
of charged fluorophores in nano metal fluidic channels by a bias
voltage.
The spontaneous emission of an atom in an infinitely long waveguide
below cutoff frequency can be completely inhibited. For a finite
waveguide, the amount of fluorescence can be emitted by the fluorophores
is determined by how far the fluorophores are from the end of
the waveguide. In our case, we use the bias between the transparent
electrode and the metal film to control the number of charged
fluorophores close to the end of the waveguide and the distance
of these fluorophores to the end of the waveguide. We are then
able to control the fluorescent emission from single pixel continuously
by adjusting the bias. The bias on each pixel can be controlled
individually by the addressable electrodes. The fluorophores
can be any type of fluorescent molecules or quantum dots.
