Patent ID: 7400097

Claim:
An organic EL display device, which includes a first and second organic EL display panels, selects either one of the organic EL display panels according to a selection signal and drives the selected organic EL display panel to perform a predetermined display, comprising a plurality of current drive circuits having output pins connected commonly to data lines or column pins of the first and second organic EL panels, for outputting drive currents for driving organic EL display elements from the output pins to the data lines or the column pins connected to the output pins, a reset circuit connected to the output pins for resetting terminal voltages of the organic EL display elements to a predetermined voltage in a reset period, and a first and second scan circuits provided correspondingly to the first and second organic EL display panels for scanning scan lines in a row direction or a vertical direction of the first and second organic EL panels, wherein one of the first and second scan circuits corresponding to one of the organic EL panels, which is to be driven, is operated in the reset period according to the selection signal and an operation of the other scan circuit is stopped or the scan operation of the other scan circuit itself is stopped for driving said one organic EL panel and ceasing the other organic EL panel.
