摘要:
An AC memory driving type self-shift type gas discharge panel prevents accidental abnormal discharges caused by deviated abnormal charges. Abnormal charges are significantly accumulated at both ends of a shift channel consisting of a regular arrangement of a write discharge cell and shift discharge cells. Therefore, conductive layers are provided adjacent to at least both ends of the shift channel in order to dissipate the abormal charges.

摘要:
A drive system for an alternating current (AC) driven type gas discharge panel in which either one of the electrode pitches of X and Y electrodes is made smaller than the other. A positive pulse voltage is applied to the electrodes of the smaller electrode pitch and a negative pulse voltage is applied to the electrodes of the larger electrode pitch, thereby to write information in a selected discharge point. The AC driven type gas discharge panel of an electrode arrangement of an asymmetrical electrode pitch is driven with a maximum write margin which does not cause half select misfire.

A touch sensing device employing a new sensing method of the present invention is composed of the sensing portion which senses capacitance change of the touch sensing electrodes forming the touch panel, plurality of capacitance compensating capacitors which are used in common for the sensing electrodes in order to compensate fluctuation of touch sensing electrodes of the touch panel, and the ROM which is storing the data for selecting the capacitance compensating capacitors. The ON-OFF output voltage levels in the touch/non-touch conditions to the touch sensing electrodes can be equalized for each electrode and thereby the touch sensing with high accuracy can be realized by selecting the capacitance compensating capacitor by means of the ROM at the time of retrieving each touch sensing electrode.
摘要:
A coordinate detecting apparatus for determining the coordinate data of a point on a plane by indicating the point with a touch of a fingertip or other load to the point. The apparatus comprises a transparent resistive film forming the plane (touch panel) and a buffer circuit operating as a voltage follower circuit having substantially infinate input impedance. The buffer amplifier is operatively connected between each selected pair of facing ends of a substantially rectangular region of the resistive film, and equalizes the potentials at the ends. The change of the impedance between one of the ends and the ground is detected in accordance with the touch of the fingertip to the touch panel and is used as an original coordinate data. Further modifications concerning the avoidance of degradation in the detection quality due to fluctuations of the impedance provided by the touch of a fingertip, for example, and the methods to perform 2-dimensional coordinate detection are described.

Thereby, the selected touch electrodes and non-selected touch electrodes are maintained at a voltage having the same phase and the same level and the inter-electrode impedance is substantially negligible.
摘要:
An improved driving system for write operations into shift rows in a multi-row self shift type gas discharge panel. Each shift row is composed of at least one shift channel comprising a regular arrangement of plural shift discharge cells and which is provided with a write electrode which defines a write discharge cell at one end of the shift channel. To the write electrodes of the shift rows, the write voltage pulse is supplied in common. When applying the write voltage pulse to the write electrode of a selected shift row, a shift voltage pulse which is the same in polarity as said write voltage pulse and has an equivalent or greater time width than said write voltage pulse is applied to the shift electrode opposing the write electrodes of the non-selected shift rows, and as a result, erroneous discharges, namely, over-write to the adjacent shift discharge cells, can be avoided by preventing the discharge of the write discharge cells of the non-selected shift rows.

A plasma display panel that can enlarge the voltage margin and can realize a stable display is provided. The plasma display panel includes first and second display electrodes X, Y for generating surface discharge and address electrodes A that cross the display electrodes via a dielectric layer. In the preparation process of the addressing for forming charge distribution corresponding to display contents, charge forming and charge adjusting are performed. The charge forming generates wall voltage having the same polarity at the same kind of interelectrode of all cells constituting the screen, for three kinds of interelectrodes, an interelectrode XY between the display electrodes, an interelectrode XA between the first display electrode and the address electrode, and an interelectrode YA between the second display electrode and the address electrode. The charge adjusting decreases the wall voltage by applying an increasing voltage that increases continuously or step by step.
