Abstract
A display apparatus is provided. The display device includes pixels, a data line, a first current compensation unit, a second current compensation unit, and a control unit. The first current compensation unit is configured for providing a first current to pixels through the data line. The first current is configured for compensating a leakage current that flows out of the data line. The second current compensation unit is configured for sinking a second current from pixels through the data line. The second current is configured for compensating the leakage current that flows into the data line. The control unit is configured for controlling the first current compensation unit to provide the first current or controlling the second current compensation unit to sink the second current according to a voltage of the data line.
