摘要： In a display device having a plurality of scanning-side electrodes arranged in one direction, a plurality of data-side electrodes arranged in a second direction intersection the first direction, and dielectric layers interposed therebetween, a modulated voltage the magnitude of which is varied according to the emission or non-emission of light is applied to the data-side electrodes, while applying a write voltage in line sequential fashion to the scanning-side electrodes, thereby performing the display control. In such a display device, the polarity of the voltage applied between the data-side electrode and the scanning-side electrode corresponding to the picture element to be driven for light emission is reversed one or more times during the period in which the write voltage is being applied to the scanning-side electrode. This serves to reduce the modulated voltage and the write voltage, thus contributing to the reduction in power consumption. Even when the modulated voltage or the write voltage is reduced, the desired brightness of emitted light can be obtained. In the case of not lowering the modulated voltage or the write voltage, it is possible to further enhance the brightness of emitted light.

摘要： A thin film EL display device is described which comprises a group of parallel scanning electrodes, a group of parallel data electrodes laid so as to extend perpendicular to the group of the scanning electrodes, and an EL layer disposed between the respective groups of the scanning and data electrodes. Each of the electrodes of at least one of the groups of the scanning and data electrodes which apply a writing voltage to the EL layer is connected with a driver circuit of high voltage breakdown characteristic having only a push-pull function or a pull-up and pull-down function. This driver circuit employs thyristors as switching elements.

摘要： When driving a thin-film EL display panel having groups of two electrodes on opposing sides of a thin-film EL layer, a voltage is applied so that the polarity of the AC pulse applied to the intersection (picture element) of opposing electrodes is the reverse of the polarity of the AC pulse applied simultaneously or nearly simultaneously to adjacent or nearly adjacent picture elements. This drive method avoids flicker caused by differing luminance intensities resulting from alternating polarity in EL matrix-type displays.

摘要： A thin-film electroluminescent display panel is sealed by a pair of glass substrates for protecting itself from the environment. A protective liquid is introduced between a counter glass substrate and a substrate for supporting the electroluminescent display panel. The protective liquid comprises silicon oil or grease which assures the thin-film electroluminescent panel of preservation of the electroluminescent display panel. The counter glass substrate is bonded to the substrate through an adhesive of, for example, photocuring resin. A capillary tube is provided within the substrate for injecting the liquid under vacuum conditions. The counter glass substrate can be plate-shaped thereby eliminating a spacer. The liquid has the ability of spreading into pin holes generated on dielectric layers, and is resistant to high voltage, high humidity and high temperature, and is inert to layers constituting the thin-film electroluminescent display panel and has a small vapor pressure and a small coefficient of thermal expansion.

摘要： A driving method is described for thin film EL display devices having an EL layer interposed between scanning side electrodes and data side electrodes which are intersected to each other. The method comprises displaying frames formed by a line sequential drive in which voltage corresponding to display data is applied to the data side electrodes. Concurrently, write pulses which are negative and positive with respect to the data side electrodes are applied to the scanning side electrodes. Further the write pulses which are positive or negative with respect to the data side electrodes are applied to the scanning electrodes. The number of light emitting picture elements of the scanning side electrodes is previously detected from display data and the width of the write pulses, which are at least one of positive or negative is controlled in proportion to the number of the light emitting picture elements. Thus, the brightness of the light emitting picture elements is uniform due to the driving circuit thereof.

摘要： An aging drive method for a thin film EL panel includes the performing a preparatory step of short-circuiting all transparent electrodes by a first connecting line, short-circuiting every other metal electrodes by a second connecting line and short-circuiting the other metal electrodes by a third connecting line. Thereafter four fields are repeatedly periodically executed for a specified period of time to thereby cause all picture elements of the panel to luminesce for aging. Each of the four fields includes a first step of applying a first voltage across the first and second connecting lines and across the first and third connecting lines to charge all the picture elements. Further a second step is included of applying a second voltage across the second and third connecting lines while holding the transparent electrodes in a floating state. This causes luminescence of the picture elements of the metal electrodes short-circuited by the second or third connecting line, with the voltage resulting from the charge on the picture elements stored in the first step and with the second voltage. The four fields are different from one another in the combination of the polarities of the first and second voltages.
