The liquid crystal array has a plurality of liquid crystal (LC) pixels, each of which is selectively darkenable. A controller is operatively connected to the liquid crystal array and configured to darken a set of the LC pixels, such that the darkened set of LC pixels limits light passage through the window in one or more selected areas. The LC pixels need not limit light passage through the entire window. The controller may determine a location of a glare source relative to the window and a location of a user proximate the window, and then darken the set of the LC pixels in an area between the glare source and the user, such that the glare source is limited from shining onto the user. The screen may be incorporated into vehicles or buildings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display and light blocking screens","description":"A light blocking screen includes a liquid crystal array mounted to a window.
