Color plasma displays

Abstract

After decades of research and development, plasma displays are finally beginning to appear in the commercial and consumer markets. Following a short review on the basic principles of direct and alternating current plasma displays, we present a summary of the status of color plasma displays. Plasma display panels (PDPs) have finally achieved luminance and efficiency values on par with hi-definition cathode ray tube monitors. Additional improvements in performance will open up a new world of large PDP displays. Ultimately, what will drive the PDP market will be continued improvements in the performance of color PDPs themselves. PDP makers are working on reducing power consumption through improved luminous efficiency and improved component materials and manufacturing methods of color PDPs. With improvements in the cell structure and driving methods, there is a good prospect of achieving a luminous efficiency of 2-3 lm/W and a power consumption of about 200 W for 50-in diagonal size.

High‐Performance Polymer Solar Cells of an Alternating Polyfluorene Copolymer and a Fullerene Derivative

“…The solvent was removed to afford the product as dark red crystals that were recrystallized from chloroform to afford 1.30 g, (59 %). 1 Poly(2,7-(9-(2¢-ethylhexyl)-9-hexyl-fluorene)-alt-5,5-(4¢,7¢-di-2-thienyl-2¢,1¢,3¢-benzothiadiazole)) (PFDTBT): 4,7-Di-2¢-(5¢-bromo)-thienyl-2,1,3-benzothiadiazole (0.15 g, 0.33 mmol) was mixed with 2,7-bis(4¢,4¢,5¢,5¢-tetramethyl-1¢,3¢,2¢-dioxaborolan-2¢-yl)-9-(2¢¢-ethylhexyl)-9-hexylfluorene (0.22 g, 0.36 mmol, 1.1 equiv), tetrakis(triphenylphosphine)Pd(0) (3.0 mg, 2.6 lmol) and toluene (6 mL) and refluxed for 10 min under N 2 . Tetraethylammonium hydroxide (1.0 mL, 20 wt.-% in water, 1.4 mmol) was added with a syringe and the mixture was refluxed for 2.5 h. Bromobenzene (0.05 g, 0.32 mmol) was added and after 1 h reflux phenylboronic acid (0.06 g, 0.5 mmol) was added.…”

“…[14] ± Formation of Polarization Gratings and Surface Relief Gratings in Photocrosslinkable Polymer Liquid Crystals by Polarization Holography** By Nobuhiro Kawatsuki,* Takako Hasegawa, Hiroshi Ono,* and Takashi Tamoto As a result of the myriad of potential applications such as optical memory devices, thin film optical filters, and integrated optical devices, photoinduced orientation in photosensitive polymer systems has received a great deal of attention. [1,2] One area well researched is holographic diffractive elements, and several types of photosensitive materials have been developed into new holographic grating devices, including photochromic polymers [3±6] and photoreactive polymers. [7,8] Numerous studies reported that irradiating polymers containing azobenzene side groups with linearly polarized…”

Breakdown in low pressure Ne gas: mechanisms and statistical analysis of time delay

“…For example, it is used in neon glow lamps, in indicators glow tube [13], in starters [14], in sodium-vapor lamp, and in gas arresters [15]. Beside of that, recently neon has applications in plasma panels, in mixture with a small percentage of Xe or Ar [16].…”

Improving motion picture quality of plasma display panels

“…Also, as light-emissive devices, PDPs have the advantages of wide viewing angle and vivid color. Many researches are being carried out to further improve the performance of PDPs [1].…”
