<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of performing display equal to initial characteristics in relatively simple configuration, a drive control method of the light-emitting device, and an electronic apparatus in which the light-emitting device is packaged. <P>SOLUTION: An organic EL display device 1 has a display panel 2, a select driver 3, a power supply driver 4, a data driver 5, a system controller 6, an ammeter 7 and a cathode circuit 8. The ammeter 7 is connected in common to cathode electrodes of organic EL elements OEL of pixels 21, and measures a current value of a current flowing to the organic EL element OEL of the pixel 21 in which a setting voltage Vd is applied to a data line Ld in a selective state, in a state of setting a driving voltage to be supplied from the power supply driver 4 to the pixel 21 and another terminal of the ammeter 7 to an equal potential. On the basis of the measured current value, light emission efficiency of the organic EL element OEL is acquired. <P>COPYRIGHT: (C)2012,JPO&INPIT |
