Abstract:
Disclosed are an upper substrate structure for a plasma display panel including a dielectric layer reinforcing color properties and a fabricating method thereof. The upper substrate structure comprises a sustain electrode formed on an upper glass substrate, a bus electrode formed on the sustain electrode, and an upper substrate dielectric layer formed over a lower part of the surface created by two electrodes and the glass substrate. There is also included a colorant having color properties of red, blue, and green colors, and a protection layer formed on the dielectric layer. The dielectric layer may include one or more colorants so that important properties of PDP such as selective brightness of desired color, color temperature, and color purity improvement can be controlled.
Abstract:
The present invention relates to a plasma display panel and a manufacture method thereof in which a color mixture of emitted light can be prevented and a contrast characteristic can be improved. The plasma display panel includes: a first barrier rib for partitioning a plurality of sub-pixels; and a second barrier rib formed to function as a boundary between one unit pixel constituting of the plurality of sub-pixels and an adjacent unit pixel, and partition the unit pixels, wherein the second barrier rib has a greater width than the first barrier rib. The method includes the steps of: coating a first and second barrier rib paste on a dielectric material formed on a glass; and placing and exposing an irregular pattern mask on the first and second barrier rib paste to form a first barrier rib pattern and a second barrier rib pattern each having a different width.
Abstract:
A plasma display panel includes a filter for controlling a light transmittance by selectively diffracting a light emitted from a discharge cell of a plasma display panel on the basis of an electric signal. A luminance efficacy can be enhanced by using the low-priced filter and the contrast of a plasma display panel can be improved.
Abstract:
A gas discharge display device is provided in which an influence of light emission of a discharge gas is reduced so that color reproducibility is improved. The gas discharge display device reproduces a color of each pixel of a color image by controlling light emission quantities of three kinds of cells having different light emission colors. The mixed color of the light emission colors of the three kinds of cells when reproducing a white color is set to a color defined by chromaticity coordinates in which a deviation from a blackbody locus is generated in a chromaticity diagram. A filter is disposed at the front side of the three kinds of cells. The filter has spectral characteristics of converting the mixed color to a color having a higher color temperature and defined by chromaticity coordinates point that is close to the blackbody locus.
Abstract:
Disclosed herein are an optical shutter for a plasma display panel and driving method thereof. According to the present invention, an optical shutter, which employs a black organic solution that moves according to the electrowetting phenomenon and a pair of electrodes for providing voltages, is disposed on a display surface of the plasma display panel. In this state, during the non-display period, voltages are not applied to the optical shutter so that light emitted from the panel cannot transmit the optical shutter. During the display period, voltages having a different polarity are applied to the electrodes of the optical shutter so that light emitted from the panel can transmit the optical shutter. It is thus possible to completely prevent weak emission generating during the non-display period where cells are initialized and selected. Accordingly, there are effects in that contrast can be improved and the picture quality can be thus enhanced.

To maximize the efficiency of utilization of mother substrates used as material for the substrates in the flat display panel to form a display screen, the flat display panel includes a display screen formed by tetragonal first and second substrates. Four sides or opposite two sides forming a tetragonal peripheral edge of the first substrate are rendered to be substantially equal to those of the second substrate, and the first and second substrate are sandwiched together with one of the first and second substrates protruding in part outwardly from the peripheral edge of the other of the first and second substrates.
Abstract:
A color filter (200) comprises pixels (13) separated from each other by partitions (14) formed on a substrate (12) so as to have a plurality of color elements of ink. Dummy pixels (13′) are formed outside the area in which the pixels (13) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film (21) covering said pixels (13) is formed so as to also cover said dummy pixels (13′).

The present invention provides an image display device capable of displaying a good image by suppressing yellowing of a glass substrate, and a high-yield manufacturing method of the glass substrate. The image display device is formed of a front-side glass substrate and a back-side glass substrate. In this manufacturing method, a glass substrate is used as the front-side glass substrate when Sn++ content in the glass substrate is a predetermined value or less, and the glass substrate is used as the back-side glass substrate when the Sn++ content exceeds the predetermined value.
