Title:
REAR PROJECTION TYPE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/129797
Kind Code:
A1
Abstract:
It is possible to provide a rear projection type display device capable of suppressing moire. A rear projection type display device projects/displays a video light generated by a DMD to a lenticular lens sheet (111) formed by a plurality of lenticular lenses (211). The display device Fourier-transforms the luminance pattern in the pixels during a black image display and satisfies the relationship A/B < 0.045 wherein A is the amplitude intensity value at the cycle matched with the one cycle of the DMD pixel and B is the average luminance value in the imaging area range.
