  • Patent number: 11978411
    Abstract: A non-emissive display includes a backlight controller sending a pulse during each sub-frame of a plurality of frames to row and column drivers that drive backlight zones. The row drivers count each pulse to keep a pulse count total, and reset the pulse count total when it is equal to a first number indicating how many row drivers are present. Each row driver activates its channels and waits for a next pulse if the pulse count total is not equal to the first number and if the pulse count total is equal to a second number indicating in which sub-frame that first driver is to be activated. Each row driver waits for a next pulse if the pulse count total is not equal to the first number and the second number. Each column driver activates its channel in response to receipt of each pulse.

  • Patent number: 11874961
    Abstract: An augmented reality device manages display of an interactive icon in a manner that enables selection by a simple and intuitive gesture. The interactive icon may initially be displayed at a predefined target position outside the fovea where it is visible in the near peripheral vision without being distracting to the user. The augmented reality device may control the icon to behave like a stationary object with respect to changes in orientation until selection or repositioning criteria are met. Upon detection repositioning criteria, the augmented reality device may reposition the icon to the target position. Selection of the icon may control functions such as alerting the user to an available notification, opening or closing a menu, or performing other actions associated with operation of the augmented reality device.
