Abstract
There is provided a power supplying apparatus for an organic light emitting display in which a control circuit is provided between the input end of the power supplying apparatus and DC-DC converters for generating power sources in order to prevent a power sequence from being changed by the unintentional formation of a current path. The power supplying apparatus for an organic light emitting display includes a first switching element having a gate electrode coupled to a first node and coupled between an input end and an output end of the control circuit, a second switching element, to whose gate electrode a control signal is applied and which is coupled between the input end of the control circuit and the first node, and a third switching element, to whose gate electrode the control signal is applied and which is coupled between the first node and a ground.
