Plasma display panels

Plasma displays are based on the use of lamp phosphors which have been investigated for over 60 years. Optimization for plasma display panels (PDPs) has only taken place in the last few years and there is much room for improvement.

Zn orthosilicate ZUjSiO iMn is a green phosphor (X 525 nm) used in fluorescent lamps, CRTs and plasma display panels. It demonstrates a low resistance to bum out, is excited by low-energy electrons and shows a linear increase in brightness with electron beam intensity. YjSiOjiCe is a highly resistant blue CRT phosphor used in projection TV tnbes (X 400 60 nm depending on the Ce content). 

Photoluminescence is a term widely applied to the range of phenomena where light emission occurs from a material after energising by photons. In this section of the book the term is specifically applied to the cases where luminescence occurs after the interaction of luminescent materials with narrow band, higher energy ultraviolet radiation, namely in lighting and plasma display panel applications.

Organic light-emitting devices (OLEDs) are one of several technologies competing for the market for next-generation emissive flat panel displays. It is the one most likely to triumph over field emission displays (basically CRT technology in miniature) and plasma display panels. 

DBDs are nonequilibrium plasmas at atmospheric pressure with applications in ozone generation, surface modification, pollution control, excimer lamps, and recently also in flat plasma display panels (Kogelschatz, 2003). Typical planar DBD configurations are shown in Figure 2. They have at... 

Panasonic is still a front runner in the field of lead-free challenges. It has announced that lead was now elimnated from their plasma display panel (PDP), which is currently one of the exceptional items of RoHS Directive.

The green primary for plasma display panels is based on Mn2+. There are disadvantages to this system. For lamps, Tb3+ emission is preferred in view of the requirement of high colour quality. 

Another major technology area that can utflize conductive IJ ink is the display market. Inkjet can be applied for both flexible and rigid displays such as electroluminescent and electrophoretic displays (including e-paper), hquid crystal displays (LCD), plasma display panels (PDP) and touch screens some functionalities have already been printed by IJ technology in certain display apphcations, for example RGB color filters. Conductive IJ is also appropriate for use in thin film transistors (TFT), disposable batteries, radio-frequency identification (RFID) tags, and a range of chemical and electronic sensors. 

The mercury-free fluorescent lamps and plasma display panels require alternative luminescent materials for efficient conversion of ultraviolet radiation to visible light. The quantum cutting (two photon luminescence or photon-cascade emission) was demonstrated in famous "Eu -Gd " pair" containing system employing the concept of down-conversion, which means that two visible photons are emitted after... 

In plasma display panels, the most severe energy loss is encountered in the discharge. This is a consequence of the small dimensions of the picture elements (pixels). The phosphors used have been known for a long hme. The operahonal lifetime of the blue emitting phosphor still poses a problem.
