摘要： In a display device such as a thin-film EL display device, etc. formed with a dielectric layer disposed between a plurality of scanning side electrodes and a plurality of data side electrodes in the direction for them intersecting to each other, a modulation voltage, varied according to gradation display data is applied to the data side electrodes, and a positive or negative writing voltage is applied to the scanning side electrodes in a line order for a gradation display different in brightness. Binary coded signals corresponding to each gradation of a gradation display are used as the gradation display data. The logical value of the binary coded signal is inverted according to the polarity of the writing voltage. Thus, a common gradation display can be performed from one binary coded signal for both the negative driving that applies a negative writing voltage and the positive driving that applies a positive writing voltage. As a result, by only by adding a data conversion circuit for inverting a binary coded signal, the function that converts the correspondence relation between the gradation to be displayed and the gradation display data depending on the negative driving or positive driving can be incorporated.

摘要： A display device, such as thin film EL display device, is formed by interposing a dielectric layer between a plurality of scanning electrodes and a plurality of data electrodes which are arranged at right angles. Modulation voltage is varied in accordance to the display data, and is applied to the data electrodes. Further, a writing voltage is applied to the scanning electrodes in sequential line order, to thereby perform gradation display. Further, the writing voltage includes a ramp voltage, which varies with time. Thus, the peak of the current flowing through the luminescent layer of the picture element, as a current contributing to the luminescence, is suppressed to a low level. contributing to the luminescence, is suppressed to a low level. Accordingly, the energization period of the current is also elongated. Thus gradation display over multiple levels is made possible and a stable display of different gradation levels is enabled.

摘要： This invention relates to gradation display by a pulse width control method (PWM method) in every pixel in a capacitive display apparatus such as a liquid crystal display apparatus. The driving voltage applied to the electrodes is varied slowly, and the number of gradations of gradation display by the PWM method is increased. Since the capacitive display apparatus is used, for each electrode further from the drive circuit, the driving pulse is more influenced and its persisting duration is extended. As a result, even in identical gradation data, uneven colors may occur. The pulse width applied to the electrodes is gradually decreased as scanning of the electrodes sequentially occurs. Therefore, the brightness of the capacitive display apparatus may be made uniform over the entire screen surface.
