Abstract: A plasma display panel induction preventing system in which when a write or erasing pulse is impressed to a selected one of electrodes of a plasma display panel, those electrodes adjoining the selected electrode are clamped at a predetermined potential or an induced voltage canselling pulse opposite in polarity to the write or erasing pulse is impressed to the adjoining electrodes, thereby preventing undesired effects resulting from an induced voltage.

Abstract: For reading out the coordinates of information on a matrix type display, a read pulse scans the display surface. In the first embodiment, the display surface is divided into a plurality of blocks in both X and Y directions. First, the scanning is carried out with regard to the blocks in the X direction. Second, when an information signal is detected in any block, the above-mentioned operation is repeated with regard to the Y direction, and the coordinates of the information signal can be read out. In the second embodiment, the display surface is divided into 2 blocks in both X and Y directions and the scanning is first carried out with regard to the two blocks in the X direction. When the information signal is detected in one of the two blocks, the block is further divided into two blocks. By repeating this process, the electrode which includes the information signal is detected. Secondly, the above-mentioned operation is repeated with regard to the Y direction, and the coordinates of the information signal can be read out. Further, in the abovementioned two embodiments, the coordinates can be read out whether the coordinates are in the fired cell or in the non fired cell without carrying out special operations.

Abstract: A plasma display panel driving system in which, at the time of interrupting a power source, the operation of a control logic circuit is stopped before an output voltage from a sustain voltage power source becomes attenuated and, at the time of applying the power source, the operation of the control logic circuit is started after the output voltage from the sustain voltage power source is established, whereby a voltage similar to an erasing pulse is prevented from impression to the plasma display panel, thereby permitting a wall charge pattern to remain alive for a relatively long time.

Abstract: The method and apparatus is disclosed for driving a plasma display panel to invert the state of a discharge cell included in the panel. The state of a selected cell is changed by a preparatory inverting pulse which is applied to a selected column (or row) electrode, and then an inverting pulse is applied to a selected row (or column) electrode to invert the state of the changed cell wall voltage. Thus, semi-selection trouble does not take place according to this invention.
