Displays comprising doped nanocrystal phosphors

Abstract

Electronic displays including CRTs and projection TV (PTV), field emission displays (FED), plasma and electroluminescent (EL) displays, all of whom involve the use of luminescent materials (active displays) for the transfer of information to an audience. The phosphor material used in these displays comprises doped nanocrystals; tiny, separated particles of the order of 100 angstroms or less and thus exhibiting quantum-confined properties. These quantum-confined particles of certain luminescent materials when doped with an activator yield ultra-fast and efficient phosphors. The resultant displays will possess high brightness and high resolution. In addition, certain of the displays will exhibit digital control and increased gray scale.
