20090079672 | PLASMA DISPLAY PANEL AND IMAGING DEVICE USING THE SAME - There is provided a PDP, in which the deterioration in the address discharge timelag with age is suppressed, which is bright, has guaranteed life, can stably be driven, is of low power consumption, high definition, and high image quality. There is provided a pair of sustaining discharge electrodes on the front substrate extending in a row direction for forming a display line, a floating electrode not connected to an external electrode is arranged on the same substrate as the pair of sustaining discharge electrode so as not to pass through a center line extending in a column direction and dividing the discharge cell into two equal parts, thereby intensifying the local potential of an area of the MgO surface not influenced by the sputtering by the sustaining discharge in the address discharge, promoting the electron emission from this area, and suppressing the deterioration of the address discharge timelag. | 03-26-2009 |
20090115332 | IMAGE DISPLAY DEVICE - A problem of the present invention is to reduce discharge delay and discharge voltage in an image display device such as a PDP using ultraviolet rays emission generated by the discharge, thereby improving image quality and reducing cost. In order to solve the above problem, according to the present invention, the image display device using the ultraviolet rays emission generated by discharge includes, within a discharge space, a phosphor where a 1/10 afterglow time is 1 ms or more and a light emitting wavelength is in a range of 200 to 460 nm in which light emitting intensity is at the maximum. Under the same condition, the effect of the invention can be improved by making the 1/10 afterglow time 8 ms or more. Further, the effect of the present invention is further effective by making the 1/10 afterglow time 100 ms or more. | 05-07-2009 |
