    Abstract: A control method for pre-warning an aging electric discharge lamp includes the steps of determining a performance parameter of an electric discharge lamp, inputting the performance parameter into an arithmetic logic unit as a standard value of the electric discharge lamp, using a detector to detect an operating performance parameter of the electric discharge lamp, and comparing a performance parameter with the operating performance parameter by the arithmetic logic unit, and if the operating performance parameter matches an aging state of the performance parameter set in the arithmetic logic unit, then the arithmetic logic unit will output an aging signal of the electric discharge lamp as a warning, and thus users can change the aging electric discharge lamp before the electric discharge lamp breaks down.

  • Patent number: 7303456
    Abstract: In an aging process in which a voltage having an alternate voltage component is applied to at least between a scan electrode and a sustain electrode so as to form a discharge dent (sputter dent) on a protecting layer, the aging discharge dent is formed so as to satisfy any one of the following. First, the discharge dent on the scan electrode-side has a width which is narrower than the discharge dent on the side of sustain electrode. Second, the discharge dent on the side of sustain electrode is formed so that the depth of the discharge dent in the area away from a scan electrode paired with a sustain electrode as a display electrode is shallower than the depth of the discharge dent in the area close to counterpart scan electrode.

  • Patent number: 7288012
    Abstract: A plasma display panel is provided that includes scan electrodes, sustain electrodes, and address electrodes. A first pulse voltage for the address electrodes or a second pulse voltage for the address electrodes is applied to the address electrodes in an aging step in which aging discharge is performed by alternately applying pulse voltage for the scan electrodes and pulse voltage for the sustain electrodes at least across the scan electrodes and the sustain electrodes. The first pulse voltage has a rising edge timing synchronized with a rising edge timing of the pulse voltage for the scan electrodes and a pulse width smaller than that of the pulse voltage for the scan electrodes. The second pulse voltage has a rising edge timing synchronized with a rising edge timing of the pulse voltage for the sustain electrodes and a pulse width smaller than that of the pulse voltage for the sustain electrodes.

  • Patent number: 7226335
    Abstract: A method and an apparatus for manufacturing an image displaying apparatus having a display panel. A first substrate of the display panel on which a phosphor exciter is disposed and a second substrate of the display panel on which phosphors emitting light by the phosphor exciter is provided, are prepared under a vacuum atmosphere. Then, the first and the second substrates are carried in a getter processing chamber or bake processing chamber, and getter processing or bake processing is applied thereto under the vacuum atmosphere. After the processing, the first and the second substrates are carried in a seal processing chamber, where the substrates are heat sealed under the vacuum atmosphere. Thus, reduction of vacuum exhaust time and a high vacuum degree in manufacturing an image displaying apparatus is attained and efficiency of manufacturing is improved.

  • Patent number: 7226331
    Abstract: In an electron source manufacturing apparatus, the quantity of heat generated from an electron source substrate is measured. A temperature of a support member for the electron source substrate is controlled based on the measured quantity of heat generated. A variation in performances of electron source substrates is suppressed, which increase their life.

  • Patent number: 7207858
    Abstract: Disclosed is a method of manufacturing plasma display panels for carrying out aging with high productivity. In an aging process for applying a predetermined voltage and driving plasma display panels 21 for display operation, each plasma display panel is set into an aging unit provided with cooling means, and the aging is carried out on the plasma display panel while cooling the plasma display panel by the cooling means provided in the aging unit. This method can thus reduce temperature rise of the panel and prevent the panel from being cracked during the aging process.

  • Patent number: 7172482
    Abstract: A PDP with superior light-emitting characteristics and color reproduction is achieved by setting the chromaticity coordinate y (the CIE color specification) of light to 0.08 or less, more preferably to 0.07 or less, or 0.06 or less, enabling the color temperature of light to be set to 7,000K or more, and further to 8,000K or more, 9,000K or more, or 10,000K or more. The PDP is manufactured by a method in which the processes for heating the fluorescent substances such as the fluorescent substance baking, sealing material temporary baking, bonding, and exhausting processes are performed in the dry gas atmosphere, or in an atmosphere in which a dry gas is circulated at a pressure lower than the atmospheric pressure.
