The clusters are activated as a unit and modulated as to brightness, but of the customized shape. All clusters can have a similar customized PSF, or the customization of each cluster may be varied in real time. Real time changes of a clusters PSF may be based, for example, an image or a region of the image to be displayed using the clusters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Custom PSFs using clustered light sources","description":"Light sources of a backlight are configured to customize the shape of light emitted from the clusters.
