    Abstract: A display device and a method of generating a data signal in the same are disclosed. In one aspect, the display device includes a display panel including pixels each configured to emit light based on a data signal. The display device also includes a power supply line configured to receive a power supply voltage from a power supply, the power supply configured to apply the power supply voltage to at least one sample pixel through the power supply line. The display device further includes a data signal generator that generates the data signal based at least in part on image data, calculate a voltage drop of the power supply voltage based on a measured level of the power supply voltage, and control the data signal based at least in part on the calculated voltage drop.
