Abstract
There is provided an apparatus for alignment of a thin-film transistor (TFT) panel and a barrier panel of a three-dimensional (3D) display. The apparatus comprises at least one light source for illuminating pixels in at least one region of the TFT panel and for illuminating at least one region of an exposure pattern of the barrier panel; a pattern recognition system for detecting light emitted from the at least one light source that is reflected by or transmitted through the 3D display, to generate alignment data relating to an alignment between the detected illuminated pixels of the TFT panel and the exposure pattern of the barrier panel; and a positioning mechanism for adjusting the relative position between the barrier panel and the TFT panel in relation to the alignment data. The at least one light source comprises at least one invisible light source which emits invisible light outside the visible region of the electromagnetic spectrum.
