Estimating the term…
An organic EL display apparatus which can improve the reliability thereof, by avoiding a leak current which occurs after an operating time, without reducing the product yield. The organic EL display apparatus is comprised of an organic EL panel section, and a driving section which has a reverse voltage restriction unit (means for restricting a reverse voltage) for restricting a reverse voltage which is applied when organic EL devices are not lighted. When a breakdown voltage with respect to a preset thickness do of the organic material layer has been Vb, the reverse voltage restriction unit will not only set the reverse voltage Vm (to be applied during a non-lighting period) to Vm<(½)·Vb, but also restrict the continuous applying time of this reverse voltage Vm within a preset period.
An organic EL display apparatus in which organic EL devices are arranged in an array of dot matrix above a substrate, and are selectively lighted or not lighted by virtue of a voltage applied in response to image signals, each organic EL device being formed by interposing an organic material layer containing a luminescent layer and having a predetermined thickness do between a pair of electrodes, said organic EL display apparatus comprising:
A method of driving an organic EL display apparatus in which organic EL devices are arranged in an array of dot matrix on a substrate, and are selectively lighted or not lighted by virtue of a voltage applied in response to image signals, each organic EL device being formed by interposing an organic material layer containing a luminescent layer and having a predetermined thickness do between a pair of electrodes,
