Abstract
A method is provided to manufacture displays such as, for example, reflective displays, electrophoretic displays or liquid crystal displays. In one embodiment of the invention, a method is provided for aligning a patterned layer of color filter elements with a display assembly. The method includes activating a first set of addressable pixel elements to change an activation state of each pixel element in the first set of the pixel elements. A required alignment of the patterned layer of color filter elements with the display assembly can be determined based at least on the activated first or a second set of the pixel elements. The patterned layer of color filter elements is aligned with the display assembly according to the required alignment.
