Abstract: A reflectivity adjustable wall unit includes a transflective layer, a reflective layer, a first sealing gap defined between the transflective layer and the reflective layer, and a liquid crystal layer in the first sealing gap. The transflective layer is used as an outer layer of the reflectivity adjustable wall unit, and reflects some of ambient light irradiated at the transflective layer while allowing some of the ambient light to pass through. The reflective layer is disposed opposite to the transflective layer. The reflective layer includes an electrochromic reflective layer, a liquid crystal electrode layer and a base substrate, and the electrochromic reflective layer, the liquid crystal electrode layer and the base substrate are sequentially arranged from an outside to an inside. The electrochromic reflective layer has variable reflectivity under control of an external control voltage; and the liquid crystal layer has variable index under control of the liquid crystal electrode layer.

Abstract: A display panel and a display device are disclosed, and in a first substrate of the display panel, the first alignment film includes a plurality of first portions corresponding to the plurality of first alignment adjustment structures each having a first surface, the fluctuation direction of the first surface and the fluctuation direction of each first portion are consistent with the alignment direction of liquid crystal molecules in the liquid crystal layer induced by the first alignment film; in a second substrate of the display panel, the second alignment film includes a plurality of second portions corresponding to the plurality of second alignment adjustment structures, the fluctuation direction of the second surface and the fluctuation direction of each second portion are consistent with the alignment direction of the liquid crystal molecules in the liquid crystal layer induced by the second alignment film.

Abstract: A 3D scene presenting method and apparatus are provided. The 3D scene presenting method for application in a 3D scene presenting apparatus includes: loading 3D scene information, where multiple pieces of 3D image information are stored in the 3D scene information, and each piece of 3D image information carries corresponding shooting position information; determining observation position information of a current observer in real time when the observer is detected in a viewable angle range of the 3D scene presenting apparatus, where the observation position information is position information of the current observer relative to the 3D scene presenting apparatus; determining a piece of 3D image information to be presented based on the observation position information and the 3D scene information; and presenting 3D content corresponding to the piece of 3D image information to be presented.
