摘要： In the gas discharge image display of this invention, the peak value of a write pulse supplied to one of two electrodes of each of fluorescent lamps aligned in a matrix form is substantially equal to the peak value of a sustain pulse supplied to that electrode. Therefore, when a row line drive circuit or a column line drive circuit supplies, in a sustain period of a fluorescent lamp to be discharged, a write pulse to another fluorescent lamp aligned in the same row or column of the matrix form, a voltage at the fluorescent lamp to be discharged can be made constant in the sustain period.

摘要： A display fluorescent lamp comprises; a dielectric cylindrical container having a large-diameter portion in which rare gas is sealed and a small-diameter portion which is almost coaxially connected with the large-diameter portion at one end of the large-diameter portion, the outside diameter thereof being smaller than that of the large-diameter portion; a light emitting portion which is formed at the other end of the large-diameter portion and has permeability; an internal electrode which is inserted into the cylindrical container from the other end of the small-diameter portion which is not connected with the large-diameter portion; a fluorescent substance layer formed on the inside face excluding that in which the light emitting portion is formed, of the large-diameter portion of the cylindrical container; and an external electrode formed on the outside face of the large-diameter portion excluding a portion in which the light emitting portion of the cylindrical container is formed, the length in the axial direction, of the small-diameter portion of the cylindrical container being set so as to be longer than an insulation distance required against a voltage to be applied between the internal electrode and the external electrode. Consequently, it is possible to ensure a sufficient insulation distance between the internal electrode and the external electrode even if the diameter of a glass valve is small.

摘要： A scan format conversion apparatus has a scanning conversion circuit which digitally converts an interlaced-scanning TV signal into noninterlaced-scanning RGB signals and synchronizing signals. A plurality of interpolation computing circuits respectively produce a plurality of interpolation signals from the signals outputted from the scanning conversion circuit by executing computing operations. A plurality of image memories respectively store the signals outputted from the interpolation computing circuits for one-frame period. A memory controller properly controls the writing and reading operation performed by the plural image memories. The apparatus generates a plurality of scan-line data by a certain amount more than those which are generated by the noninterlaced-scanning operation, and then selects scan-line data available for a display unit with uniform alignment from the increased scan-line data.

摘要： A large scale display device capable of displaying half tones composed of a display panel having a large number of display elements arranged in a matrix form with each element having a memory function. The overall range of an image signal is divided into a plurality of steps or levels. A first level signal is used to control the timing of turning on the display element while a second level signal is used to control the timing of turning off the display element so that the light emitting time period is made proportional to the amplitude of the image signal. Both the number of decisions required and the number of times of controlling the display elements are reduced over prior constructions so that various half tones can be readily displayed.
