  • Patent number: 11705062
    Abstract: A method for an electronic device merges a subset of display brightness and corresponding ambient light value pairs selected from a brightness adjustment model and one or more user defined display brightness and corresponding ambient light value pairs received from user input occurring at a user interface of the electronic device to obtain a merged brightness adjustment model dataset. The method filters the merged brightness adjustment model dataset to obtain a filtered brightness adjustment model dataset and extracts a merged brightness adjustment model from the filtered brightness adjustment model dataset. One or more processors of the electronic device control a display brightness of a display of the electronic device using the merged brightness adjustment model.

  • Patent number: 11663983
    Abstract: Techniques are disclosed for lighting displays such as those associated with electrophoretic display (EPD) devices such as e-readers or any other display technologies or applications. In an embodiment, an EPD device is provided with a number of internal LEDs or other suitable light source generally disposed along at least a portion of the display perimeter. The light can be activated in situations where the available ambient light is inadequate for viewing the display. Light from the light source is distributed across the display, and in some embodiments, can be adjusted to provide a desired degree of brightness. The light can be turned on or off via an existing single press-button or otherwise tactile, physical user interface that serves multiple functions. This user interface can be readily found and engaged by the user without the benefit of sight.

  • Patent number: 11640063
    Abstract: Head-mounted virtual and augmented reality display systems include a light projector with one or more emissive micro-displays having a first resolution and a pixel pitch. The projector outputs light forming frames of virtual content having at least a portion associated with a second resolution greater than the first resolution. The projector outputs light forming a first subframe of the rendered frame at the first resolution, and parts of the projector are shifted using actuators, such that physical positions of light output for individual pixels occupy gaps between the old locations of light output for individual pixels. The projector then outputs light forming a second subframe of the rendered frame. The first and second subframes are outputted within the flicker fusion threshold. Advantageously, an emissive micro-display (e.g., micro-LED display) having a low resolution can form a frame having a higher resolution by using the same light emitters to function as multiple pixels of that frame.

  • Patent number: 11631376
    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.
