Plasma Display Materials

Abstract

Recent trends in the development of plasma display panels (PDPs) are reviewed in this article with special emphasis on materials. New developments in the panel structure, discharge gases and phosphors used, and drive methods have improved many of the display characteristics over a wide range of operating conditions. As a result, much progress has been seen in large-scale panel development; for example, 50-in. and 61-in. PDPs have been commercialized. Improvements in phosphor longevity, discharge gas efficiency, and characteristics of the protective layers can be attributed in part to materials solutions. The longevity of the blue phosphor has been improved by the development of new materials and a greater understanding of the phosphor deterioration mechanism. The luminous efficiency has been greatly increased by the use of high-density Xe gas. The protective-layer characteristics have been improved as a result of advancements in processes, materials, and analytical methods.

Synthesis and luminescence properties of microemulsion-derived Y3Al5O12: Eu3+ Phosphors

“…For improving the performance of displays, developing high-quality phosphors is a must. Besides the luminescence yield, the particle size, density, and morphology of phosphors also have to be well controlled [1][2][3][4][5][6]. The requirement that efficient phosphors utilize discharged inert gas as an excitation source has motivated vacuum ultraviolet (VUV) excited luminescence studies.…”

“…The requirement that efficient phosphors utilize discharged inert gas as an excitation source has motivated vacuum ultraviolet (VUV) excited luminescence studies. When excited at 147 nm by discharged Xe gas, few phosphors have shown the potential for plasma display panels applications [1]. The phosphors used in PDP include BaMgAl 10 O 17 : Eu 2+ and Y 2 SiO 5 : Ce 3+ for blue emission, BaAl 12 O 19 : Mn 2+ and Zn 2 SiO 4 : Mn 2+ for green emission, and YBO 3 : Eu 3+ for red emission [7][8][9][10][11][12].…”

Morphology control and luminescence properties of BaMgAl10O17:Eu2+ phosphors prepared by spray pyrolysis

“…As a blue component, Eu 2+ -doped barium magnesium aluminate with the typical composition of BaMgAl 10 O 17 (BAM:Eu 2+ ) has been widely used in fluorescent lamps and recently in plasma display panels (PDP) due to its high luminescence efficiency and good chromaticity [1][2][3][4][5][6]. Conventionally, the BAM:Eu 2+ phosphor is prepared by solid state reaction process, i.e., firing a mixture of BaCO 3 , Eu 2 O 3 , Mg(OH) 2 Á MgCO 3 , Al 2 O 3 together with a small amount of additional flux such as AlF 3 or MgF 2 at about 1600 1C in a reducing atmosphere, and the resulted phosphor contains irregularly shaped and aggregated particles (5-8 mm) which are not good for high screen brightness and high resolution [7].…”

Combinatorial deposition by r.f. magnetron sputtering using subdivided powder targets as new development method for thin-film phosphors

“…[1][2][3][4][5] However, the optimization of thin-film phosphor characteristics is markedly more difficult than developing the powder constituents. For the purpose of resolving this problem, we have proposed a new technique utilizing combinatorial deposition by r.f.…”
