Particularly, the auto-stereoscopic display technology is leading the trend because it is user-friendly and convenient for user to view 3D imageries. The research of this thesis is based on the circular sweeping of two-dimensional LED arrays. For the purpose of eliminating blind spots of viewing, the proposed display technology uses the nonplanar LED arrays which are constructed by a number of linear LED arrays and arranged in a nonplanar manner. When rotating at an adequate speed, the effect of three-dimensional imagery can be obtained without blind spots of observation. The proposed algorithm can detect intersections between sweeping planes and triangular surfaces that constitute the 3D object to be displayed, and will locate the intersection points in three-dimensional physical space. Through the pipeline of two stages, the data of intersection points latched in the register will be outputted to control the state of LEDs, while the data of intersection points next to the current sweeping plane and triangular surfaces will be accessed from memories and latched in the register in the same time period. The proposed algorithm and the associated mechanism are realized and proved to be able to display three-dimensional objects in real space without blind spots.
