摘要： In a field emission cold cathode device having a block defined by a contour and a plurality of holes arranged in the block, each hole is uniform in shape to obtain a uniform electric current in the block when emitter cones are located in the uniform holes. A distorted hole is not arranged in the block or holes which are susceptible to be distorted are shifted or moved to other zones which are not distorted. Such uniform holes can be also obtained by preparing mask patterns of different sizes and by transcribing the mask patterns onto photoresist.

摘要： There is provided a field emission cold cathode including (a) an electrically conductive substrate, (b) a plurality of emitter cones formed at a surface of the substrate, (c) a gate electrode being formed as a first resistive layer and a second resistive layer formed on the first resistive layer, and (d) an insulating layer sandwiched between the substrate and the gate electrode. The first resestive layer has a resistivity higher than a resistivity of the second resistive layer. The second resistive layer is composed of metal or a metal compound. The gate electrode and the insulating layer are formed with a plurality of openings in alignment with each other, with the emitter cones being formed in the openings in alignment with each other, with the emitter cones which includes a predetermined number of the emitter cones. The substrate is formed with trenches surrounding each of the groups when viewed in a direction of a normal line of the substrate, and trenches are filled with an electrical insulator. The field emission cold cathode can avoid being destroyed due to abnormal discharge occurring between an emitter cone and a gate electrode without reducing the density at which the emitter cones can be arranged on the substrate.

摘要： There is provided a field emission cold cathode including a semiconductor substrate, an insulating layer formed on the semiconductor substrate, an electrically conductive gate electrode layer formed on the insulating layer, a plurality of cavities being formed throughout both the insulating layer and the gate electrode layer, a conical emitter formed on the semiconductor substrate in each one of the cavities, and an insulating wall formed at least in the semiconductor substrate so that the insulating wall surrounds each one of the cavities. The insulating wall partitions the semiconductor substrate into a first group of blocks located at a marginal end of the semiconductor substrate and a second group of blocks located within the first group of blocks. Each one of the first group of blocks is designed to have a greater area than an area of each one of the second group of blocks. The field emission cold cathode makes it possible to uniformize an emission current in all of the blocks to thereby provide uniform brightness to images in a display area.

摘要： A LC panel for use in a projection LCD device includes a source driver IC operating in a frame-inversion driving scheme. The luminance gradient caused by the frame-inversion driving scheme in the active-matrix substrate is cancelled by the luminance gradient caused by the heat generated by the source driver. A heat adjusting element is provided for the source driver IC, wherein the heat adjusting element is either a radiator or a heater depending on the relationship of the magnitude between the luminance gradients caused by the frame-inversion driving scheme and the source driver IC.

摘要： A field emission cold cathode sends forth uniform emission over the entire emission area and realizes, when applied to a flat screen display device and the like, a uniform brightness of images over the entire display area, providing a high quality field emission type cold cathode. An electron tube is equipped with the cold cathode. The cold cathodes structurally prevent a prolonged electric discharge with the use of trenches. Non-uniformity of resistance, resulting from the difference in extension of the depletion regions in each block divided by the trenches, can be prevented by an arrangement of blocks in which each block divided by trenches is placed to have a prescribed distance from an adjacent block, which makes emission currents in all blocks within the formed emitter area uniform at the time of normal operation, and thereby a good form in which depressions in the block corner sections are well suppressed can be obtained.

摘要： A field emission cold cathode comprises a silicon substrate, a first insulation layer defining peripheries of a first and second feeder area disposed concentric with each other, a cathode area having a plurality of conical emitters overlying the first insulation layer, and a gate electrode layer having a plurality of openings each for applying electric field to each of the conical emitter. The cathode area has a narrower width than the width of the underlying insulating zone, wherein the cathode area has peripheries apart by fixed distance L from the peripheries of the feeder area. In this configuration, a uniform emitter current can be attained among the emitters to thereby obtain a high luminescence and high resolution CRT.
