ORGANIC LIGHT-EMITTING DISPLAY COMPRISING A CURRENT INTEGRATOR

The present invention provides an organic light-emitting display comprising: a display panel comprising sensing lines connected to pixels; a current integrator that receives current from the pixels through the sensing lines connected to a first input terminal and receives a reference voltage through a reference voltage line connected to a second input terminal and that swaps the path through which the current applied through the first input terminal flows and the path through which the reference voltage applied through the second input terminal is supplied; a sampling part that comprises a first sample & hold circuit for sampling a first output voltage of the current integrator and a second sample & hold circuit for sampling a second output voltage of the current integrator, subsequent to the first output voltage, and that outputs the voltages sampled by the first and second sample & hold circuits simultaneously through a single output channel; and an analog-to-digital converter that converts the voltages received from the single output channel of the sampling part to digital sensed values and outputs the digital sensed values.
