摘要： In driving a thin film EL display panel providing the matrix arrangement of translucent data electrodes and metal scanning electrodes, the data pulse is supplied to the selected translucent data electrodes in such a relation that it rises in advance of the scanning pulse to be supplied to the opposing metal scanning electrodes. Thereby, fluctuation of brightness due to the influence of electrode resistance of the translucent data electrodes can be eliminated, and a uniform and distinct display can be attained.

摘要： An EL device having an electrode arrangement including first electrodes and at least one row of second electrodes intersecting the first electrodes and energized by a combination of the first and second electrodes. The second electrodes are divided into a plurality of sub-electrode portions. The electrode arrangement is such that the first electrodes each comprise a plurality of segments that are commonly-connected and intersect different sub-electrode portions. Another electrode arrangement is such that the first electrodes are arranged in a belt form and intersect different sub-electrodes portions in a meander manner.The EL device can be applied to an electrophotographic printing system as an optical system for forming a latent image. EL elements are repeatedly energized with the same data to give a sufficient intensity of light on a light sensitive medium, and deenergized for a time in which the intensity is decreased to a low level.

摘要： A method for driving a thin film EL display device comprising the steps of clamping the Y side scanning electrodes selectively and sequentially to a reference voltage and applying the display voltage selectively from the X side data electrodes. In addition, the non-display voltage which is lower than the display threshold voltage, is applied to the non-selected data electrodes and the non-selected scanning electrodes are floated.

摘要： In a driving device of an active matrix type liquid crystal display unit including a liquid crystal display panel, a scan driver, and a data driver, a data voltage controlling apparatus is provided to achieve digital multiple gray-scale levels with little flickering. The data voltage controlling apparatus supplies the data driver with a combination of two different data voltages picked up from a plurality of digital data voltages previously set. The combination of two different data voltages are, for example, a combination of different waveforms, a combination of negative level and positive level, and a combination of two different voltages having at least a voltage difference. Further, a division of T-V characteristics and an exchange of data voltages are carried out to reduce the flickering.

摘要： In a driver circuit of direct drive matrix type LCD panel, a quantity of ON-STATE cells (or OFF-STATE cells) displayed on the just previous scan electrode is counted and a quantity of ON-STATE cells (or OFF-STATE cells) to be displayed on a present scan electrode is also counted. A compensation voltage is generated according to a predetermined relation based on a difference of the two above-counted quantities, and is superposed onto drive voltages of unselected scan electrodes or of each of data electrodes, in a polarity that an undesirable spike voltage induced on unselected cell voltage is cancelled, in synchronization with selection of the present scan electrode. The compensation voltage may be generated according to a digital difference of the two quantities or to a change in an analog voltage representing the counted quantity. The above-described relation of the compensation voltage versus the counted quantity difference may be proportional or may be given with a predetermined specific relation to meet the panel characteristics. The compensation voltage may be a flat voltage during the period for selecting the single scan electrode or may be of a spike waveform. Amplitude of this spike is determined by the above-described predetermined relation. An irregular panel brightness caused from spike voltages induced from data electrode voltage application is cancelled.
