  • Patent number: 11955038
    Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may have a number of independently controllable viewing zones. Each viewing zone displays a respective two-dimensional image. Each eye of the viewer may receive a different one of the two-dimensional images, resulting in a perceived three-dimensional image. The electronic device may include display pipeline circuitry that generates and processes content to be displayed on the lenticular display. Content generating circuitry may generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. Pixel mapping circuitry may be used to map the two-dimensional images to the array of pixels in the lenticular display. The array of pixels may have a diagonal layout. An offset map may be used by the pixel mapping circuitry to account for the diagonal layout.

  • Publication number: 20240112628
    Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.

  • Patent number: 11804706
    Abstract: An over-voltage protection circuit includes an over-voltage detection circuit, a voltage generator and a switch for providing over-voltage protection between two pins of a USB Type-C port. The over-voltage detection circuit provides an over-voltage signal according to the level of the second pin.
