Title:
SYSTEM AND METHOD FOR SUB-PIXEL ELECTRONIC ALIGNMENT
Document Type and Number:
WIPO Patent Application WO2004071939
Kind Code:
A3
Abstract:
In one embodiment, a delay circuit (511,512) is configured to delay pixel information from an image source, such as a frame buffer (508). The delay circuit (511,512) may be configured to delay the pixel information by an amount of time that would move a pixel projected on a surface by a distance less than a dimension of the pixel. A light modulator (300) may modulate a light beam onto a surface, such as a display screen, based on the delayed pixel information. This advantageously allows for sub-pixel electronic alignment.
