Abstract
A compensation circuit and a display device are disclosed. The compensation circuit includes a gain compensator that calculates a voltage drop amount using a first pixel driving voltage output from a power supply and a second pixel driving voltage fed back from a wire of a display panel. The voltage drop amount is amplified by a predetermined gain value. A first voltage compensator generates a high-potential gamma reference voltage by adjusting a first reference voltage using the voltage drop amount and a second voltage compensator generates a low potential gamma reference voltage by adjusting a second reference voltage using the generated voltage drop. The gain value is a value calculated using voltages at two predetermined points within the wire of the display panel. Accordingly, an individual compensation circuit optimized depending on a position where the pixel driving voltage is fed back can be provided.
