    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 video display monitor, such as a plasma monitor, which uses a subfield method which overlaps weighted multiple binary video images in a time base for display. The stable driving of a plasma display panel may be assured and display in the 256 grey-level may be maintained although vertical synchronizing frequency of the input video signal changes. A vertical synchronizing measurement unit measures the vertical synchronizing frequency of the video signal, and a subfield number adjustment unit adjusts the number of subfields in accordance with a measured vertical synchronizing frequency. The stable driving of the plasma display panel and display in grey levels may be assured by selecting a ROM table with an output bit width equivalent to the number of subfields to be output from multiple ROM tables used for converting the number of bits in the input signal.

    摘要: A method of memory-driving a DC gaseous discharge panel and circuitry therefor are disclosed. To generate a write discharge on a desired display cell, while a scan pulse Pscn having a pulse width of τscn is applied to a cathode associated with the cell, a display anode is held in its high level or ON level. To prevent the write discharge from being formed, while the scan pulse Pscn is applied to the cathode, a non-write pulse Pnw having a pulse width of τnw is applied to the display anode. The pulse width τnw is selected such that the duration of the pulse Pnw (τscn - τnw) is shorter than the statistic time lag of the start of a discharge at which a discharge cell generating a write discharge first appears. For a sustain discharge following the write discharge, sustain pulses Psus are applied to the cathode after the scan pulse Pscn for a predetermined period of time such that they do not coincide with the non-write pulses as to the timing. As a result, stable discharge and therefore high quality display is insured even when the scanning period must be reduced in order to, e.g., enlarge a screen.
