A graphic fluorescent display device is disclosed which is capable of effectively eliminating a streak pattern occurring right below cathodes. The fluorescent display device is constructed in such a manner that an electric field controlling electrode is disposed on the surface of a cover plate opposite to a substrate having anodes formed thereon, and potential positive with respect to the cathodes is applied to the electric field controlling electrode so that electrons emitted from the cathodes may be diffused by the positive electric field of the electric field controlling electrode.

A linear electrode construction for a fluorescent display device which is capable of providing the high densification of luminous display is disclosed. The linear electrode construction includes two electrode frames each comprising a plurality of linear electrodes arranged side by side at intervals of a predetermined distance and each having a fine wire-like electrode portion and a connecting terminal portion formed at one end of the electrode portion. The fine wire-like electrode portions are uniformly applied thereto tension to prevent the sagging in the operation. Also, a process for preparing such a linear electrode construction is disclosed.

摘要:
A fixed pattern display device of the dynamic drive type with high definition including cathodes formed into a fine pattern by conventional photolithography. The cathodes are made of a metal material having a low resistance and arranged on an insulating substrate in the form of wiring patterns for fixed display segments of each of display patterns together with the display patterns. ITO which is resistant to water is exposed in the form of anodes each acting as a common electrode, resulting in arrangement of any protective film being eliminated.

In an organic electroluminescence (EL) device including a display section having one or more light emitting units and a monitoring section positioned outside the display section and having one or more monitoring cells, each of the light emitting units and the monitoring cells has a cathode, an anode and at least one organic EL layer positioned between the cathode and the anode. In the organic EL device, either cathodes or anodes of the light emitting units and the monitoring cells is transparent and a current passing through an anode and a cathode of a monitoring cell is monitored to control the light emitting units.

A multi-color organic EL device capable of preventing color mixing due to leakage luminescence while incorporating therein luminous layers formed by mask deposition techniques. Anodes, a hole transport layer, luminous layers different in type from each other and cathodes are laminated. In such a laminate structure, the luminous layers different in type which are arranged adjacently to each other are constructed so as to permit the luminous layer increased in band gap to get between the luminous layer decreased in band gap and the hole transport layer.
摘要:
A color filter capable of being uniformly formed without any deformation of a light-permeable anode conductor and prevented from being adversely affected by etching for formation of the anode conductor. A light-permeable anode substrate free of any deformation is uniformly formed thereon with anode conductors, on which color filters are formed of a mixture of a composite oxide pigment and a conductive material so as to cover the anode conductors. The color filters each are formed by arranging a color filter material in a predetermined pattern, followed by calcination. Then, phosphor layers are deposited on the color filters. The phosphor layers are electrically connected through the conductive material of the color filters to the anode conductors. A thickness of the color filters and a particle diameter of the conductive material are determined to be substantially the same, so that the color filters exhibit conductivity only in a direction of thickness. Thus, contact between the color filters adjacent to each other does not cause electrical connection therebetween.
摘要:
A display device capable of preventing vibration of control electrodes stretched in an envelope. The control electrodes are divided into two assemblies or a main control electrode assembly and an auxiliary control electrode assembly arranged in contact with or in proximity to the main control electrode assembly so that vibrations of both control electrode assemblies may damp each other due to a difference between natural frequency therebetween, thereby restraining vibration of the control electrodes.

An organic electroluminescence (EL) device doping material which is thermally stable, having a high melting point, and doping with which improves stability of a luminous layer formed as a thin layer. An organic EL device 1 comprises a glass substrate 3, an anode 2 made of transparent indium tin oxide (ITO), an electron hole implanted transporting layer 4 of TPD, a luminous layer 5, and a cathode 6 made of Mg. The luminous layer is made of Alq3 doped with 1 mol % of Al2O (SABF)2 as a metal chelate complex having ligands composed of SABF skeletons. When plus DC voltage is applied to the anode 2 and minus DC voltage, to the cathode 6, the luminous layer 5 emits yellow electroluminescence of 16400 cd/m2 at maximum with 15 V. The external quantum yield was 0.1891 m/W. The luminous layer of the organic EL device is thermally stable and hard to be deteriorated.
