Once identified the system may determine a face position for the unintended viewer. The system may modulate the voltage applied at a third electrode on the color filter layer of the LCD to achieve a certain off-axis contrast that may reduce the unintended viewer's visibility of the LCD without restricting the visibility of the intended viewer. Ultimately, the present disclosure provides enhanced privacy options for the intended viewer with a lightweight, inexpensive, and highly transportable system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Improving viewer privacy by controlling off-axis contrast with face recognition","description":"The present disclosure relates identifying an intended viewer and an unintended viewer of a liquid crystal display (LCD) using face recognition technology.
