    Abstract: A display driving method is provided. The method comprises: determining whether scanning of at least one area of display areas is completed (S1); adjusting light-emitting luminance of display light source corresponding to the at least one area after the scanning of the at least one area is completed, such that display luminance of the at least one area maintains within a specified range to eliminate picture flicker (S2). The display driving method is capable of reducing commendably the change of display luminance of the at least one area by adjusting the light-emitting luminance of display light source corresponding to the at least one area, so that picture flicker caused by over change of the display luminance would be avoided. There are provided a display driving method and apparatus and a display device comprising the display driving apparatus.

    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.
