Abstract
Natural lighting profiles are affected in a building facade and internal transparent membrane using a transparent sheet having one or more pixel elements, wherein each of the pixel elements is capable of being driven to control opacity (by shading). A programmable controller is used to send control commands to control opacity of the pixel elements, wherein the percentage of light transmitted through the display panel forming part of the facade is controlled via the controller.
