Abstract: A display panel driving apparatus includes a data driver, a gate driver, an extra resistance part through which a constant current passes, and a circuit configured to generate a first gamma voltage, and output a first extra gamma voltage indirectly to the data driver through the extra resistance part. The data driver is configured to generate a data signal based on the first gamma voltage and output the data signal to a data line of a display panel. The gate driver is configured to output a gate signal to a gate line of the display panel.

Abstract: An organic light-emitting display includes: a pixel comprising a pixel circuit; a power supply configured to supply a first power voltage to the pixel circuit; a voltage divider configured to generate a power division voltage by dividing the first power voltage; a converter configured to generate a first digital value by performing an analog to digital (A/D) conversion of the power division voltage; a storage unit configured to store a first reference digital value generated by the converter, the first reference digital value corresponding to a first reference voltage and a second reference digital value generated by the converter, the second reference digital value corresponding to a second reference voltage that is different from the first reference voltage; and a voltage level determiner configured to determine a level of the first power voltage based on the first digital value, the first reference digital value, and the second reference digital value.
