Abstract
A display device includes a display panel including data lines, gate lines, and pixels connected to the data lines and the gate lines, a data driver configured to drive the data lines, a plurality of gate drivers, each configured to drive a corresponding portion of the gate lines, and a plurality of feedback lines connected to one of the data lines at a plurality of measurement positions corresponding to the plurality of gate drivers. The data driver applies a test voltage to the data line, receives the test voltage as a plurality of feedback voltages through the plurality of feedback lines, and determines gate shift amounts at the plurality of measurement positions corresponding to the plurality of gate drivers based on the plurality of feedback voltages. The gate drivers apply gate signals to the gate lines that are shifted by the determined gate shift amounts.
