Abstract
A display panel comprises a first substrate and a second substrate which are assembled to form a cell and a control unit. The first substrate is provided with a plurality of first light-emitting units which are double-sided light emitting devices thereon, and the second substrate is provided with a plurality of second light-emitting units which are double-sided light emitting devices thereon. The control unit is configured to control the first light-emitting units and the second light-emitting units to emit light or not to emit light. The display panel further comprises a grating-function layer interposed between the first substrate and the second substrate. The grating-function layer comprises controllable light blocking regions and controllable light transmissive regions, and the light blocking regions and the light transmissive regions cooperate with the first light-emitting units and the second light-emitting units to realize single-sided display or double-sided display.
