DISPLAYS HAVING BUILT-IN MOIRÉ REDUCTION STRUCTURES

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.
