摘要:
A segmented optical shutter (200) is used with a high-resolution display (101) to provide a dynamic user interface (400) for a portable electronic device (100). To reduce optical interference corresponding to a correlation function for transmitted light occurring between the photospacers (209) in the segmented optical shutter (200) and the black matrix (107), the photospacers (209) are disposed along a light transmitting substrate (204) of the segmented optical shutter (200) in a quasi-random arrangement. The quasi-random arrangement, which may include varying the horizontal and vertical placement of the photospacers (209), repeating asymmetrical subsections of photospacer configurations, varying the size or shape of the photospacers (209), or combinations thereof, misaligns the photospacers (209) relative to the black matrix (107) or other elements to reduce optical interference and moiré patterns that may otherwise be perceptible to a user.

Disclosed are methods of user interfaces of electronic devices having a displays configured to annunciate wallpaper images wherein a wallpaper image includes image data. Image data can be characterized, for example, by the luminance levels of pixels of the image and/or the power needed to display the image. An image characteristic threshold is related to current drain impact, for example, in terms of luminance and/or power needed to display an image. A disclosed method can include receiving the image data of the wallpaper image and determining whether the image characteristic of the image data (such as luminance level at a given percentile) exceeds the image characteristic threshold. A disclosed method can further provide generating a user interface notification relating to the image characteristic exceeding the image characteristic threshold and relating to the current drain impact of displaying the image as wallpaper.
