Patent ID: 7157858

Claim:
A self light emitting display module comprising a self light emitting display unit composed of a light emitting display panel in which a large number of pixels including self light emitting elements having a diode characteristic are arranged in a matrix pattern at intersection positions between scan lines and data lines and drive means for selectively driving and lighting the respective self light emitting elements in the light emitting display panel, trouble detection means for detecting trouble in the self light emitting display unit, and a memory means for storing detection results which are obtained by the trouble detection means, wherein the trouble detection means is constructed to comprise reverse bias voltage applying means for applying a reverse bias voltage to the cathode side of the self light emitting element in a non-light-emitting-state of said element and potential determination means for determining whether or not the electrical potential at the anode side of the self light emitting element in a state in which the reverse bias voltage is applied to the cathode side of said element is a predetermined value or greater, so that trouble in the self light emitting display unit is detected by the potential determination means.
