Abstract:
A method of driving an organic thin-film EL display device in which one or a plurality of organic multilayered thin films including at least one organic emission thin film are clamped in a matrix between a plurality of scanning electrodes comprising unit electrodes and a plurality of data electrodes comprising unit electrodes, at least one of said scanning electrodes and said data electrodes being translucent, wherein when a forward bias is applied between a selected unit electrode of said scanning electrodes and a selected unit electrode of said data electrodes to cause a selected pixel concerning both of said selected unit electrodes to emit light, and a reverse bias is applied between nonselected unit electrodes of said scanning electrodes and nonselected unit electrodes of said data electrodes, thereby preventing crosstalk caused by a semi-excited state of said nonselected pixels, all of said scanning electrodes and all of said data electrodes are short-circuited once, immediately before a predetermined unit electrode of said data electrode, which should be selected in accordance with selection of each of said unit electrodes of said scanning electrodes, is selected, to set all of said pixels at a zero bias.
