Abstract:
An EL display device, comprising:an EL display panel including a row-and-column matrix array of scan electrodes and data electrodes with EL elements being formed at intersections of said scan electrodes and said data electrodes;scan electrode driver circuits for applying to said scan electrodes a scan voltage changeable in polarity once per each positive and negative field; anda data electrode driver circuit for applying to said data electrodes a data voltage that causes said EL elements to operate in one of a light emissive and a light non-emissive state;said scan electrodes being arranged so that an off-set voltage is applied thereto during times other than when said scan voltage is applied; andsaid data electrodes being arranged so that a predetermined voltage is periodically applied thereto to create a potential difference applied to the EL display panel of substantially zero, wherein no voltage is applied for a time period between applications of said scan voltage to said scan electrodes.
