    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.

    摘要： A plasma display having a quartet type pixel structure provides a high grade and excellent picture quality picture and maintains good white balance and excellent intensity levels. The plasma display comprises a reference circuit phi for outputting a control signal based on the least significant bit of a digitized green video signal and a timing signal and an arithmetic circuit 8 for performing an arithmetic operation on the output of the reference circuit. As a result of this arrangement, the least significant bit information, that was lost by halving the green signal value to maintain the white balance is incorporated in the halved green signal based on a timing signal, thereby realizing 256 intensity levels without degrading the halftone in the video picture.

    摘要： A PDP driving method that reduces the reset voltage of the PDP driving waveforms to make it possible to use low-voltage elements and to achieve high contrasts is disclosed. Since conventional PDP waveforms require very high reset voltages, it causes a problem of intense background light emissions, low contrasts, use of high-voltage components, and increased circuit costs. According to the driving waveforms of the present invention, relative voltage differences between the address electrode and the X electrode and between the X electrode and the Y electrode are considered to design waveforms of low reset voltages, thereby providing high contrasts and low-cost circuit.
