Color image processing for flat panel visual display modeling

Cathode ray tubes (CRT's), liquid crystal displays (LCD's) and many other flat panel displays use spatially separated color pixel components to produce color images. The new manufacturing techniques for flat panel displays support a wider range of possible pixel shapes and geometric layouts than those possible with CRT manufacturing technology. We describe an algorithm comprised of several image processing steps that allows the user to specify arbitrary color component shapes and to specify the geometrical description for the layout of these components. The algorithm is based in part on the theory of periodic plane tilings. This theory is quite general and it allows for the unified treatment of the display pixel shapes and layouts that may arise in practice. This algorithm may be used by display designers to simulate various display designs in order to study tradeoffs for the visibility of sampling and display reconstruction artifacts.
