Abstract:
An organic EL display apparatus for displaying an image thereon, said apparatus comprising:a plurality of organic EL elements arranged in a matrix form on a plane, each one of said organic EL elements including a pair of electrodes and an EL layer provided between said pair of electrodes and being able to emit light in response to an image signal supplied thereto, said EL layer generating a photoelectric voltage thereacross in response to an incident light thereon; driving means for successively driving selected ones of said organic EL element by successively supplying drive currents across said electrodes of the selected one of said EL elements in response to an image signal supplied to said apparatus; and signal generating means for generating an electric signal while detecting in sequence the photoelectric voltages each appearing across said electrodes of either ones of said organic EL elements.
