摘要： Techniques and display devices that provide a built-in Moire reduction structure in a display screen are disclosed. The built-in Moire reduction structure is configured to suppress spatial frequencies that are associated with the sub-pixel level periodicities in the light emitted by the colored sub-pixels of the display screen, and hence, reduce the Moire patterns that might otherwise be produced when images presented on the display screen are captured by a digital image capturing device having a periodic light-sensing structure. The built-in Moire reduction structure is a blur layer placed on the viewer side of the screen and separated by a spacer layer from the pixel layer of the display screen. The blurring power of the blur layer is controlled to substantially preserve the pixel-level resolution of the display screen.

摘要： Techniques and medium structures for reducing signal distortions due to mass transfer from the medium surface to the optical head in optical storage devices in both far-field and near-field configurations. In one embodiment, a transparent capping layer is formed on a storage medium to have a sufficient thickness so that a beam spot size of an optical beam on the medium surface is sufficiently large to make a power density of the beam less than a threshold power density for mass transfer from the medium to the optical head.
