Electroluminescent display technologies

A.N. Krasnov, ELDs rise on organic wings electroluminescent-display technology is being rescued from its industrial niche by implementations using organic materials, Inf. Display, 18 18-21, 2002. 

The fluorescence of polysilanes has received much attention in recent years, in part because of the discovery that some poly silanes are electroluminescent, and so may have applications in display technology. Fluorescence spectra, quantum yields, lifetimes and other properties for dialkylpolysilanes have been thoroughly investigated by Sun and coworkers.98 Dialkylpolysilanes exhibit fluorescence of a rather normal type, in which the emission is a mirror image of the absorption, with a rather small Stokes shift. This suggests that the emission takes place from a highly delocalized state, probably an... 

The discussion presented in this section has centred on the principles of the most important colour display technologies, and is by no means exhaustive. There are numerous other technologies, currently either available or under development. Examples include electro-chromic, field emission and thin-film electroluminescent displays, the commercial viability of which will be determined in the years to come. 

Only a decade after the first demonstration of electroluminescence in polymeric materials, the performance of PLEDs now appears to meet many of the requirements for applications at the low performance end of the display market, and the field has matured to the point of commercial exploitation the most current overview of the state-of-the-art can be foimd in an outstanding review (4). A number of electronics and polymer companies, including Cambridge Display Technology Ltd., Covion, Dow Chemical Co., Philips Electronics, and Uniax Corp., have...

Since the discovery of electroluminescence (EL) in poly(phenylene vinylene)(PPV), the use of organic materials in light emitting devices (LEDs) has received increasing attention [1]. There is now intense interest in the application of low molecular weight materials and organic polymers [2,3] to a variety of display technologies [4]. 

Peripheral Circuits. The drive and address circuitry that operates a flat panel display is approximately equal in both cost and importance to the display panel itself. It is for this reason that the use of mass produced 10- to 20- volt integrated circuits (ICs) to drive and address LCDs and OLEDs makes these displays so competitive versus other technologies, which require 125- to 150-volt circuitry, e.g., plasma panels and inorganic electroluminescent displays.
