Abstract
A display unit, a display substrate, a driving method of the display substrate and a display device are provided. The display unit includes a first electrode, a second electrode disposed above the first electrode, a functional layer disposed between the first electrode and the second electrode, and the functional layer includes a luminescent material with electrical bistable characteristics. The display unit is provided with the functional layer of the luminescent material with the electrical bistable characteristics, so that the display unit can emit light when being in a high conductivity state and still keep emitting light after being de-energized, and does not emit light when being in a low conductivity state, thereby realizing display and non-display of the display unit.
