摘要: The black matrix of Liquid Crystal Displays (LCDs) degrades image quality of projection system and Head Mount Displays (HMDs) by appearing as dark boundaries around each pixel. Therefore, an image smoothing technique is required to suppress these boundaries. With proposed image smoothing grating, not only the horizontal but also vertical parts of black matrix fade away into the first order diffraction beams. Moreover, the contrast of the smoothed image is close to the original value, because the second order beams can be designed to be negligible.
