Patent number: 10120184Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.Type: GrantFiled: November 21, 2016Date of Patent: November 6, 2018Assignee: Amazon Technologies, Inc.Inventors: Erno Hermanus Antonius Langendijk, Christian Etienne Hendriks, Tulasi Sridhar Reddy Guntaka, Steven Ramos Carneiro, Pavel Novoselov

Patent number: 10120187Abstract: A system, computer readable medium, and method for sub-frame scan-out are disclosed. The method includes the steps of dividing a frame into a plurality of slices. For each slice in the plurality of slices, the steps further include sampling a sensor associated with a head mounted display to generate sample data corresponding to the slice; adjusting one or more parameters associated with rendering operations for the slice based on the sample data; and rendering primitive data associated with a model according to the rendering operations to generate image data for the slice. Each slice is a portion of the frame and corresponds to different sample data from the sensor. Thus, adjusting of the parameters is different for each slice of the frame.Type: GrantFiled: February 18, 2016Date of Patent: November 6, 2018Assignee: NVIDIA CORPORATIONInventors: Craig Michael Wittenbrink, Ziyad Sami Hakura

Patent number: 10120188Abstract: A head-up display device includes a display element, a beam splitter, a movable mirror, first and second mirrors, and a movable unit. The display element emits light to form a display image. The beam splitter being an optical member that reflects light or through which light is transmitted, reflects light emitted from the display element. The movable mirror reflects light reflected off the beam splitter. The first and second mirrors that reflect light movable mirror, or through which the light transmitted through the beam splitter is transmitted, project a virtual image. The movable unit adjusts a distance between the movable mirror and the beam splitter to adjust a projection distance of the virtual image.Type: GrantFiled: August 8, 2017Date of Patent: November 6, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Keiichi Matsuzaki, Michihiro Yamagata
