摘要： A highly reliable plane display panel which has a large operating margin for making displaying operations and can stably display high-quality pictures, a method for manufacturing the panel, a controller for controlling the panel, and a method for driving the panel. The plane display panel is composed of a front glass substrate (1) provided with common electrodes and individual electrodes (3, 3a and 3b) which can be driven individually at every display cell, and a back glass substrate (10) having recessed sections which become discharging spaces. At the time of driving the plane display panel, the polarity of the wall charges accumulated on a dielectric layer (5) during displaying operations is inverted by applying voltage pulses to the individual electrodes (3) separately from the displaying operations. Thereafter, the electric field of the wall charges having the inverted polarity is added to the driving voltage, so that discharge can surely take place by applying voltage pulses for display to the electrodes (3).

摘要： A common electrode and an individual electrode are provided in plural pairs on a first transparent substrate, and recesses are formed in a second substrate in positions corresponding to the pairs of electrodes to define discharge cells of display cells. The display cells of a display panel can be individually driven on the cell-by-cell basis and the planar panel has a reduced thickness. A driving circuit for changing luminance in accordance with the number of pulses applied to the individual electrode within a unit time to make gradation display is provided, and gradation control is achieved by performing switching control for each of the individual electrodes provided independently of one another in one-to-one relation to the display cells. A voltage pulse is applied to the individual electrode to reverse the polarity of wall charges accumulated on a dielectric layer, and a voltage pulse is then applied to the common electrode so that an electric field of the wall charges caused upon the reversal of the polarity is additionally applied. Thereby provided are a planar display panel which can set a large control margin in the display operation, ensure stable display, and present gradation display with high reliability and quality, as well as a manufacturing method, a controller, and a driving method for the planar display panel.
