PULSE WIDTH MODULATED DISPLAY WITH IMPROVED MOTION APPEARANCE

摘要

A field sequential pulse width modulated display system (10) comprises a digital micromirror device (DMD) (24) having a plurality of micromirrors that each selectively pivot to reflect light onto a screen (28) to illuminate a corresponding pixel. A driver circuit (30) controls the DMD (24) responsive to sequences of pulse width segments formed by a processor (31). The processor (31) forms the pulse width segment sequences to alter the pixel brightness for a given one of a set of primary colors within a range of brightness values between adjacent pixel brightness boundaries, with each segment for each color interleaved with the segments for the other colors.
