Patent number: 10325541Abstract: Large-format display systems having color pixels and white pixels are disclosed. In an embodiment, the system includes a video camera, a video processor, and a large-format display that includes the color pixels and the white pixels. The video processor processes the video signal from the video camera, but the video processor does not perform a white-to-RGB conversion. Instead, the information for the white pixels is sent directly to the large-format display to form the color display image. A viewer's visual system performs the white-to-RGB conversion when viewing the color display image. A method of forming the color display image using color pixels and white pixels is also disclosed. Methods of performing color matching using the color pixels and white pixels are also disclosed.Type: GrantFiled: December 21, 2015Date of Patent: June 18, 2019Assignee: Production Resource Group, L.L.C.Inventors: Jeremy Hochman, Robbie Thielemans
