1. An organic light emitting display (OLED) device comprising:

  • an OLED panel for displaying an image;

    a power detection unit for generating a power detection signal from the OLED device when the OLED device turns on;

    a testing image generation unit for generating a testing image signal;

    a selection unit for selecting to transmit the test image signal upon receiving the power detection signal;

    a timing control unit for driving the OLED panel to display a test image according to the test image signal;

    a current-adjusting unit for adjusting a real-time current complying with a predetermined current and holding the real-time current complying with the predetermined current if the current-adjusting unit detects that the real-time current of the OLED panel provided by a power circuit is lower than the predetermined current when the test image is displayed; and

    a normal image signal input terminal for inputting a normal image signal,wherein the selection unit selects to transmit the normal image signal upon receiving the normal image signal, and the OLED panel displays a normal image according to the normal image signal from the timing control unit and the hold real-time current complying with the predetermined current provided by the current-adjusting unit.
