Abstract: The present application discloses a display panel free of a liquid crystal layer including a base substrate, and an array of a plurality of pixels on the base substrate, each of the plurality of pixels comprising at least one subpixel. Each subpixel includes an electroactive layer on the base substrate; and a light transmission layer on the base substrate configured to be actuated by the electroactive layer so that light transmittance of the light transmission layer in the at least one subpixel changes in response to a change in an electrical signal applied to the electroactive layer to achieve levels of gray scale; wherein the light transmission layer is reversibly deformable.

Abstract: A plastic frame includes a first frame having a first frame surface and a first end portion and a second end portion opposite to each other, and a second frame having a second frame surface, an end portion of the second frame being connected to the first end portion of the first frame. The first frame surface and the second frame surface are located on the same side of the plastic frame. A first height difference between the first frame surface at a first end portion of the first frame and the second frame surface is smaller than a height difference between the first frame surface at a middle portion of the first frame and the second frame surface. The first height difference may be, for example, 0.1-0.3 mm.

Abstract: A display panel and a method for manufacturing the same, an electronic paper and a driving method thereof are provided. The display panel includes: a first base substrate, a second base substrate arranged oppositely to the first base substrate, and multiple temperature-induced transmittance reversible components which not contacted with each other and arranged in an array between the first base substrate and the second base substrate. Each of the temperature-induced transmittance reversible components includes: a temperature-induced transmittance reversible unit and a temperature control unit. The temperature control unit is used to adjust temperature of the temperature-induced transmittance reversible unit to control transmittance of the temperature-induced transmittance reversible unit with respect to the visible light.
