摘要： An EL display in which expansion of dielectric breakdown occurring at any one of EL elements is inhibited. Scan electrodes are arranged to receive an offset voltage Vm at those instances other than during application of a scanning voltage thereto in a positive field, while a predetermined voltage is applied to data electrodes to prevent voltage from being applied to EL elements immediately after application of the scan voltage. Accordingly, even where dielectric breakdown occurs at any one of the EL elements due to application of a light emission driving pulse voltage, it is possible to inhibit current flow between the scan electrodes and the data electrodes to thereby inhibit further subsequent dielectric breakdown.

摘要： An Electroluminescent display device is designed not to display residual images due to electric charges stored in electroluminescent pixels or to make them invisible, when the device is turned on again. The stored charges are eliminated at the time a normal display on the panel is turned off at an end of an operation, by scanning pixels at least one time while giving a non-activating data voltage thereto. Alternatively, upon turning on the panel, pixels which were activated in a previous use are all lit at least one time, thereby making the residual images invisible. Thus, the residual images stored in a previous operation are not shown or made invisible when the electroluminescent display device is turned on next time.

摘要： An electroluminescent display panel having a matrix electrode structure composed of scanning electrodes and data electrodes is driven by supplying scanning voltages either alternately or simultaneously from both sides thereof in order to eliminate uneven luminance along a longitudinal direction of the scanning electrodes. Two scanning electrode driving circuits, each connected to each side of the scanning electrodes, may be used. Since an overall luminance of the electroluminescent display panel is a summation of the luminance obtained by scanning the scanning electrodes from one side and the other side, the luminance along the scanning electrodes becomes uniform by scanning from both sides. The data electrodes may be driven from both sides thereof in the same manner as in the scanning electrodes.
摘要翻译：具有由扫描电极和数据电极构成的矩阵电极结构的电致发光显示面板通过从其两侧交替或同时地提供扫描电压来驱动，以消除沿着扫描电极的纵向的不均匀的亮度。可以使用各自连接到扫描电极的每一侧的两个扫描电极驱动电路。由于电致发光显示面板的整体亮度是通过从一侧和另一侧扫描扫描电极而获得的亮度的总和，所以通过从两侧扫描，扫描电极的亮度变得均匀。数据电极可以以与扫描电极相同的方式从其两侧驱动。

摘要： A number of capacitive pixels formed in an electroluminescent display panel are selectively charged and discharged by the driving device. The driving device is composed of a charging circuit connected between a power source and the pixels and a discharging circuit connected between the pixels and the ground. Both the charging and discharging circuits include a respective inductive coil that constitutes a series L-C circuit together with the capacitive pixel. Since the pixels are charged and discharged through the series L-C circuit, impulse current otherwise flows in and out of the pixels is suppressed, and thereby radio noises generated by the impulse current are prevented.
