    摘要： The display device of the invention comprises a plurality of scanning lines (Wscan and Escan) which are selected successively, a plurality of data lines (Data) to which the writing electric current (Idata) in accordance with brightness information is supplied according to the scanning line selection, and a plurality of pixels (PX) arranged at intersecting points between the scanning lines and the data lines. Each of the pixels comprises a light emitting element (OLED), a driving transistor (TFT4), a capacitor (C) connected to the gate (Nd) of the driving transistor for accumulating writing data, a first transistor (TFT1) which is turned on during writing period in which the scanning lines are scanned and which connects the data lines and the drain of the driving transistor, and a second transistor (TFT2) which is turned on during the writing period and which short-circuits the gate and drain of the driving transistor. With such a structure, the light emitting element can be driven with a driving electric current equivalent to the writing electric current, irrespective of variations in characteristics of the transistors,

    摘要： A picture displaying method is for displaying a picture by means of a plurality of picture displaying units. A picture signal representing the picture is supplied to each of the picture displaying units. A first picture displaying unit displays a first part of the picture according to the picture signal and produces a start pulse signal after displaying of the first part of the picture. A second picture displaying unit displays a second part of the picture according to the picture signal in response to the start pulse signal.

    摘要： A power supply device for driving liquid crystal which generates four liquid crystal drive voltages V1 and V4 between first and second reference voltages, the power supply device comprising: a voltage division circuit 102 which divides a voltage between voltages between voltages V1 and V5 and generates four pairs of first voltages NV1 to NV4 and second voltages PV1 to PV4; and four impedance conversion circuits 103 and 104 which generate impedance converted liquid crystal drive voltages V1 to V4 based on the four pairs of the first and second voltages. Each impedance conversion circuit comprises voltage follower type of differential amplifier circuits 120 and 110 to which a pair of the first and second voltages is input, and an output circuit 130 which is driven by the differential amplification circuits. The N-type transistor 134 and P-type transistor 132 in the output circuit are independently driven by the first and second output voltages VN, VP from the differential amplification circuits 120 and 110.

    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.
