摘要： PROBLEM TO BE SOLVED: To solve the problem of the entire discharge cells on a panel being unable to be driven normally, because the entire panel emits light due to discharging that is generated at impressing of a priming pulse prior to a write period and an erase pulse, after a sustaining period to lower contrast and also because erroneous discharge occurs because a discharge margin is narrowed, in such a manner that the pitches of the discharge cell are narrowed accompanying high-definition. SOLUTION: A stepped pulse waveform of at least two or more steps is used at impressing of an initializing pulse, prior to a write period and an erase pulse after a sustained period, to suppress light emission due to unwanted discharges, and a stepped pulse waveform of at least two or more steps is used for a write pulse and a sustaining pulse, so as to suppress delays in discharges; thereby, efficiency and contrast are improved significantly and a high quality PDP is realized.

摘要： PROBLEM TO BE SOLVED: To provide a high-intensity gas discharge type display that is low in sustaining voltage, high in efficiency and low in cost. SOLUTION: The display emits electrons from an electrode having a cold cathode structure to sustain discharge. An insulator film of MgO or the like porous on an electron theory basis is formed on the electrode. The surface is charged in advance to create a potential gradient between the electrode and the insulator surface, the potential gradient then causes electrons to pass through a dielectric and discharge Xe gas, and ultraviolet rays generated thereby excite a phosphor to display an image.

摘要： PROBLEM TO BE SOLVED: To solve such problem that metal fittings connected to a glass substrate in vicinities of upper and lower end parts of a plasma display panel(PDP) are electrified and then the electrostatic potential difference between upper and lower parts of the panel reaches several tens kV to frequently cause an abnormal discharging in the scanning direction in the case of picture display by a conventional driving method. SOLUTION: The scanning sequence of scanning lines in an address period is inverted every field or sub-field to suppress the occurrence of abnormal discharging due to the unbalance of a stray potential which is caused by asymmetrical discharging in an address operation, and thus a PDP of high definition and high picture quality is realized.
