Abstract
PURPOSE:To input freely coordinates precisely, by putting coordinate detecting electrodes on a field generating electrode so that a pulse voltage is induced and detecting the lowering of the level based on the approach of fingers to recognize input coordinate points. CONSTITUTION:In case that key arrangement information of a keyboard is displayed on a gas discharge panel PDP, a holding voltage pulse applied periodically to X-side and Y-side display electrode groups 13 and 14 alternately is induced effectively to X-side and Y-side coordinate detecting electrode groups 26 and 27 from a field generating electrode 25, and therefore, the level of the induced voltage pulse between both corresponding coordinate detecting electrodes is lowered considerably when the operator touches a key K with his fingers. This lowering is detected by a detecting circuit 4 cooresponding to pertinent electrodes, and the detection output is transferred as X-side and Y-side coordinate input data, namely, key-in signals from an interface to the external central processing device.
