Abstract

A display device and a detection method applied to the display device are provided. The display device includes a display panel, a source control circuit, and a leakage estimation circuit. The display panel includes pixels being arranged in M columns, wherein at least one panel-partition is defined on the display panel. The source control circuit includes M source drivers which respectively provide data voltages to the M columns of pixels. The leakage estimation circuit includes an evaluation circuit, a defect detection circuit, and a mode-switch. The evaluation circuit controls the defect detection circuit to perform a leakage estimation procedure so that a leakage current corresponding to the panel-partition is estimated when the at least one mode-switch is turned on.
