摘要： A scan driver IC for an EL element in an EL display device supplies, in a positive field, a positive polarity scan voltage and an offset voltage which is higher than ground to scan side driver ICs from voltage supply circuits, and the scan side driver ICs set voltage of scan electrodes to be the offset voltage in the positive field, together with outputting the positive polarity scan voltage to the scan electrodes during electroluminescence timing. Consequently, a voltage of Vr-Vm is applied to the scan side driver ICs, and so the breakdown voltage can be lowered by an amount corresponding to the offset voltage Vm. Circuits for providing such voltages, for providing alternating current drive voltages, and for reducing power consumption of the drive circuits are also disclosed.

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 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： A flat display panel having electroluminescent layer and scanning and data electrodes is driven by driving circuits connected to the respective electrodes. Scanning voltages are sequentially supplied to the scanning electrodes one by one, and data voltages are supplied to the data electrodes in synchronism with the scanning voltages, thereby selectively imposing composite voltages on pixels formed at each intersection of the scanning and data electrodes. The pixels on one scanning electrode that is already scanned are charged to a level of a data modulation voltage to prevent a harmful and useless turnaround current from flowing into the scanned pixels when other scanning electrodes are scanned. The pixels on other scanning electrodes that are not yet scanned may be charged to the modulation voltage level at the same time the scanned pixels are charged. Since the turnaround current is thus eliminated, uneven brightness among scanning electrodes otherwise appearing on the display panel is suppressed.

摘要： An electroluminescent matrix display device which displays images with uniform brightness on its panel having connecting terminals for both scanning and data electrodes formed on one side of the panel is disclosed. Scanning electrodes requiring larger current than data electrodes are formed vertically on the panel so that they can be connected directly to the terminals formed on the bottom side of the panel, and data electrodes are formed horizontally to be connected to the terminals at the bottom side through wiring leads. Since the wiring leads have different lengths and resistances from one another, the resistances are compensated or adjusted by changing widths of the wiring leads or adding compensating resistors thereto so that the wiring resistances become uniform or differences thereof are reduced. Running directions of the scanning and data electrodes may be exchanged. In this case, wiring resistance differences for the scanning electrodes are eliminated or reduced in a similar manner as done for the data electrodes. In both cases, uniformity of image brightness is much improved.

摘要： A display panel driving system, constituted in such a manner that the occurrence of a display irregularity on the display panel can be suppressed without regard to the characteristics or the driving condition of the display panel, is disclosed. An up-counter counts the number of the picture elements which emit light when the EL display panel is horizontally scanned, and the counting result thus obtained is outputted as an addressing signal to an EEPROM. Stored in the EEPROM are data maps MAP, MAP in which pulse width data are written at a plurality of addresses corresponding to the counting ranges of the up-counter. A signal generation means outputs a blank signal BLK which determines the pulse width of a data voltage on the basis of the pulse width data addressed by the up-counter.
