<p>PURPOSE: A stacked organic light emitting device is provided to connect unit light emitting units in parallel, thereby operating with a lower operating voltage than a serially stacked organic light emitting device. CONSTITUTION: A first light emitting unit(130a) and a second light emitting unit(130b) are formed on the upper/lower parts of a first electrode(120). A second electrode(140a) and a third electrode(140b) are formed on the lower part of the first light emitting unit and the upper part of the second light emitting unit respectively. An operation controller(200) is electrically connected to a first electrode, a second electrode, and a third electrode. The operation controller includes a first voltage adjusting unit(230a) and a second voltage adjusting unit(230b). The second voltage adjusting unit adjusts the voltage applied to the third electrode.</p> |
