Abstract

The invention provides a display device and a driving method thereof, and belongs to the technical field of display. The problem that an existing electrophoretic display device can only conduct black and white gray scale display, or imaging color saturation is decreased when color display is conducted can be solved. The display device comprises a first substrate and a second substrate which are arranged oppositely, electriferous opaque particles, a first electrode and a second electrode are arranged between the first substrate and the second substrate, the electriferous opaque particles are located in a pixel region formed by the first substrate, the second substrate, the first electrode and the second electrode in an enclosing mode, a first electric field is formed by the first electrode and the second electrode, part of the electriferous opaque particles move to the first electrode under the action of the first electric field, and the other part of the electriferous opaque particles move to the second electrode under the action of the first electric field, so that light irradiated on the second substrate is sent out through the pixel region and a color film layer of the first substrate.

Description
