  • Publication number: 20230395015
    Abstract: A display may have a display panel with an array of pixels formed from light-emitting diodes. Optical films that help collimate and homogenize light from the light-emitting diode pixels may overlap the light-emitting diodes. A transparent cover may overlap the display.

  • Publication number: 20230195824
    Abstract: Methods and systems for recommending content redirection are described herein. A remote computing device may establish a connection in which to transfer content between an application hosted on the remote computing device and a client device. The remote computing device may render graphics of a user interface for the application. If the remote computing device determines that to render the content of the application with use of one or more resources of the remote computing device would exceed a threshold, the remote computing device may provide, to the client device, the instructions enable the client device to render a portion of the content locally on the client device rather than on the remote computing device. In this way, the user's experience of the application may be improved without causing more computing resources on the remote computing device.

  • Patent number: 11624913
    Abstract: An optical display system includes an information display (image-generating) component, a polarization dependent image offset optical element and possibly also a polarization rotator. By controlling the image offset optical element either by direct applying voltage or by controlling the polarization of the displayed light through the polarization rotator, the display pixels can be switched by a certain portion. By switching between offset and non-offset state with appropriate image displayed, the resolution as observed by the users can be enhanced.
