Abstract:
An autostereoscopic 3D display assembly includes pixels configured to generate a first image intended for a user's left eye, and a second image intended for a user's right eye. Each of the images is projected with a respective line pattern, where the bright portions of the left eye line pattern alternate with the bright portions of the right eye line pattern. The left eye and right eye line patterns are formed using a grating or a double grating. In one embodiment, right eye pixels and left eye pixels each include a double grating, with a different offset between the first grating and second grating to generate the different line patterns. In another embodiment, right eye pixels and left eye pixels each include a grating and one or more micro-LEDs, with a different offset between the grating and the micro-LEDs to generate the different line patterns.
