Abstract
A pixel structure, a driving method thereof, and a display device are provided. The accommodation chamber of the pixel structure includes: a first substrate and a second substrate opposite to each other, an accommodation space being formed therebetween; a light absorption layer in the accommodation space, including a flowable insulating liquid layer; a transparent thin film in the accommodation space, located between the insulating liquid layer and the second substrate, a refractive index of the transparent thin film being less than or equal to that of the insulating liquid layer. The accommodation chamber is in one of the at least two following states: in a first state, the insulating liquid layer is separated from the transparent thin film such that light rays from the second substrate are totally reflected; and in a second state, the insulating liquid layer and the transparent thin film at least are partially in direct contact.
