Display device

A display device, comprising:

• a display panel comprising a pixel, the pixel having a light-emitting element configured to emit light, the pixel connected to a data line and a sensing line;
• and
• a display driver configured to supply a data voltage to the data line and receive a sensing signal from the sensing line,
• wherein the display driver comprises:
• a first switch configured to supply a reference voltage to the sensing line;
• a second switch configured to supply a low-potential voltage to the sensing line;
• a sampling-holding module comprising a third switch connected to the sensing line, an analog-to-digital converter connected to the third switch and for outputting sensing data, and a holding capacitor configured to hold a voltage applied to an input terminal of the analog-to-digital converter;
• a fourth switch configured to supply the low-potential voltage to the analog-to-digital converter;
• and
• a fifth switch configured to supply a sensing reference voltage to the analog-to-digital converter, the sensing reference voltage for setting a range of the reference voltage during a sensing process of the reference voltage.
