| 主权项 | 1. An organic light-emitting display apparatus comprising: a display comprising a plurality of pixels arranged in an array; a sensor configured to detect respective current characteristics of the plurality of pixels; a current sensor configured to receive a first current from a first pixel of the plurality of pixels, to output a first voltage corresponding to the first current, to receive a second current from a second pixel of the plurality of pixels, and to output a second voltage corresponding to the second current; a level shifter configured to receive the first and second voltages and to generate first and second shift voltages respectively corresponding to the first and second voltages, an intermediate voltage of the first and second voltages being equal to a conversion reference voltage; and an analog-to-digital converter (ADC) configured to receive the first and second shift voltages and to output a digital value corresponding to a difference between the first and second shift voltages based on the conversion reference voltage. | ||
