ORGANIC LIGHT EMITTING DIODE SURFACE LIGHT SOURCE APPARATUS FOR COMPENSATING UNEVENNESS OF ELECTRICAL AND OPTICAL CHARACTERISTICS

摘要

PURPOSE: An organic light emitting diode(OLED) surface light source apparatus is provided to control electrical and optical characteristics generated in a light emitting region, thereby improving the uniformity of the OLED surface light source apparatus.;CONSTITUTION: A driving part(510) outputs a plurality of power sources. A surface light source part(520) comprises a substrate(521), a light emitting region(522), a plurality of positive contact points(523,524) and a negative contact point(525). The light emitting region emits light using a plurality of power sources supplied from the driving part. The positive contact point and the negative contact point respectively supply the plurality of power sources outputted from the driving part to the light emitting region. A control part(530) controls the size of the plurality of power sources outputted from the driving part.;COPYRIGHT KIPO 2012
