Abstract
A display device is provided. The display device includes a display panel and a plurality of driving chips. A detection circuit of each of the driving chips includes a plurality of sub-detection circuits. Each of the sub-detection circuits is correspondingly coupled to one data line through a control switch corresponding to each of the sub-detection circuits. The display panel further has a plurality of detection pads. A plurality of detection signals received by the detection pads are transmitted to the data lines through the sub-detection circuits. A portion of the data lines correspondingly coupled to each of the driving chips is grouped into a data line group. Resistance of the sub-detection circuits correspondingly coupled to the portion of the data lines in the data line group is caused to continuously gradually vary.
