Abstract:
A display device in which an image with a wide color reproduction range and bright red can be displayed is provided. The display device is a display device such as, for example, a liquid crystal display device, a cathode ray tube, an organic electroluminescent display device, a plasma display panel, and a field emission display. The display device includes a display surface including a pixel having red, green, blue, and yellow sub-pixels, wherein the red sub-pixel preferably has the largest aperture area.

Abstract:
Flat-panel type picture display device having a luminescent screen and a large number of electron propagation ducts operating by means of electron wall interaction. At a given resolution, hexagonal phosphor dot patterns in which dots are horizontally staggered generally produce fewer artefacts than in a 90.degree. tilted orientation. An addressing system for withdrawing electrons from the propagation ducts and for directing them towards the luminescent screen is preferably formed as a multistepped structure with a preselection structure of rows of preselection electrodes and a fine-selection structure of rows of fine-selection electrodes. To interconnect the fine-selection electrodes in parallel in a minimal number of groups, it is advantageous when the fine-selection electrodes are arranged parallel to the preselection electrodes.

Abstract:
Disclosed is a flat panel display device including a first substrate; an electron emitting region formed on the first substrate; a second substrate opposing the first substrate with a predetermined gap therebetween; a vacuum assembly being formed by the first and the second substrates; and a light emitting region including a phosphor layer with a predetermined pattern and emitting light by electrons emitted from the electron emitting region, and an anode formed on one side of the phosphor layer, wherein the projections and depressions are formed on the anode, or on the second substrate.
Abstract:
In an image display device, an opening area per unit area of opening portions formed in a BM film which is formed on an inner surface of a face substrate is set such that the opening area is gradually decreased from a center portion to a peripheral portion of an image display region. By preventing the generation of color mixing in a peripheral portion of an image display region attributed to the printing position displacement of phosphor film or missing of dots in the phosphor film in pixels, it is possible to provide the image display device which can enhance a yield rate and, at the same time, can acquire an image display of high color uniformity over the whole surface of the image display region.
Abstract:
A method for forming a cathodoluminescent screen by forming cathodoluminescent films on the inner surface of screen panel for a field emission display by a screen printing, a spray, or an electrodeposition process. The field emission display cathodoluminescent particles for improving a luminescent emission efficiency, wherein the improved cathodoluminescent particles are formed by coating a uniform phosphor material on the surfaces of cathodoluminescent particles by an atomic layer epitaxy.

Abstract:
In an image display apparatus which has a multi-electron beam source in which a plurality of electron emission elements are connected in a matrix pattern using a plurality of data electrodes and a plurality of scanning electrodes, and a fluorescent screen having phosphors of three primary colors R, G, and B corresponding to the electron emission elements, natural white color emission is obtained while suppressing a decrease in G luminance, using, e.g., a checkerboard layout which has a G spatial resolution higher than the R or B spatial resolution and includes more G phosphors than the R or B phosphors. For this purpose, the scanning electrodes connected to the electron emission elements corresponding to the G phosphors are electrically independent from those connected to the electron emission elements corresponding to the R or B phosphors, signal components corresponding to the G phosphors and signal components corresponding to the R or B phosphors are extracted from an image signal for a 1-line period, and the scanning electrode connected to the electron emission elements corresponding to the G phosphors and those connected to the electron emission elements corresponding to the R or B phosphors are selected during successively the 1-line period.
