摘要:
A method for manufacturing a light-emitting element includes removing a resin layer (3) of a multilayer composite (30) by thermal decomposition. The multilayer composite includes a luminescent layer (2) containing a plurality of luminescent particles (20), the resin layer disposed on the luminescent layer, and a light reflection layer (6) disposed on the resin layer. The resin layer contains a solid resin (4) and a plurality of resin particles (5) dispersed in the solid resin. A temperature at which the reduction in mass of the resin particles measured by thermogravimetric analysis reaches 70% is lower than a temperature at which the reduction in mass of the solid resin measured by thermogravimetric analysis reaches 70%.

A flat panel display comprising: a backplate structure (330) comprising (a) a backplate (331), (b) an electron emitting structure (332) overlying the backplate and having electron-emission sites (361-365) situated generally in an emission-site plane (303), and (c) a primary structure (334) overlying the backplate and having a non-planar approximately equipotential surface extending generally along the emission-site plane at a distance therefrom which varies between first and second values (d b ,d s ), the backplate structure having an electrical end located in an electrical-end plane (304) extending generally parallel to the emission-site plane at a distance therefrom which lies between the first and second values; a faceplate structure (320) coupled to the backplate structure to form a sealed enclosure; and a spacer (340) situated between the backplate structure and the faceplate structure for resisting external forces exerted on the display, the spacer having a backplate-side electrical end situated along the primary structure at a location spaced apart from the electrical-end plane, the spacer being provided with compensation structure for controlling the potential field along the spacer so that electrons emitted by the electron emitting structure strike target areas on the faceplate structure rather than striking outside the target areas due to the spacer's backplate-side electrical end being spaced apart from the electrical-end plane.

An oxide composite particle, characterized in that it comprises an oxide particle matrix and, incorporated therein, at least one fine gold particle or comprises an oxide particle and, carried fixedly on the surface thereof, at least one fine gold particle, and absorbs a visible light having a specific wavelength; a phosphor such as the one emitting red color, characterized in that it have a thin film comprising above oxide composite particles on the surface of particles thereof; a method for producing the phosphor, which comprises incorporating phosphor particles into a dispersion of gold colloid/oxide composite particles, agitating the resultant mixture, and taking out the precipitated phosphor particles, followed by drying; a color filter, characterized in that at least one color filter layer formed inside a panel is a thin film comprising the above oxide composite particles. The above-mentioned phosphor and color filter are excellent in optical characteristics, heat resistance and non-toxicity, and is free from the adverse effect on the radiation of a photoresist with ultraviolet rays; and a color display manufactured by using the color filter exhibits good luminous chromaticity and is excellent in brightness and contrast.

Plasmabildschirm ausgerüstet mit einer Leuchtstoffschicht, die einen blauen, Eu 2+ -aktivierten Leuchtstoff und einen UV-C-Licht emittierenden Leuchtstoff enthält. Durch Beimischung eines UV-C-Licht emittierenden Leuchtstoffes zu einem Eu 2+ -aktivierten Leuchtstoff oder Beschichtung eines Eu 2+ -aktivierten Leuchtstoffes mit einem UV-C-Licht emittierenden Leuchtstoff oder Bedeckung einer Basisschicht aus einem Eu 2+ -aktivierten Leuchtstoff mit einer Deckschicht aus einem UV-C-Licht emittierenden Leuchtstoff wird die Photodegradation der Eu 2+ -aktivierten Leuchtstoffe im VUV-Bereich deutlich vermindert.

摘要:
A flat panel display having a backplate structure (330), a faceplate structure (320), and a spacer (340) situated between the two plate structures is configured so that the electric potential field along the spacer approximates the potential field that would be present at the same location in free space, i.e., in the absence of the spacer, between the two plate structures. Consequently, the presence of the spacer does not significantly affect the trajectories of electrons moving from the backplate structure to the faceplate structures. Alternatively, the spacer is arranged to produce electron deflection that largely compensates for undesired electron deflection which occurs during earlier electron travel from the backplate structure to the faceplate structure. The net electron deflection is small.
