A display device whose pixels being embedded with a memory is disclosed. These pixels each includes: a capacitor; a switching unit between the display unit and the capacitor, being turning on during the sampling period; and a voltage detecting circuit for detecting the voltage between the capacitor and the switching unit. Besides, the display unit also includes: a first capacitor voltage source connected to a terminal of the capacitor which is not connected to the voltage detecting circuit, and applying a predetermined voltage within the variation range of the voltage state of the display unit on the capacitor in the sampling period; and/or a second capacitor voltage source, being connected to a terminal of the display unit which is not connected to the switching unit, and applying a predetermined voltage within the variation range of the voltage state of the display unit on the display unit in the sampling period.
