Abstract A multi-view display module using microelectromechanical system (MEMS) projectors is proposed to realize ultra-large screen autostereoscopic displays. The module consists of an array of MEMS projectors, a vertical diffuser, and a lenticular lens. All MEMS projectors having different horizontal positions project images that are superimposed on the vertical diffuser. Each cylindrical lens constituting the lenticular lens generates multiple three-dimensional (3D) pixels at different horizontal positions near its focal plane. Because the 3D pixel is an image of a micro-mirror of the MEMS projector, the number of 3D pixels in each lens is equal to the number of MEMS projectors. Therefore, the horizontal resolution of the module can be increased using more projectors. By properly modulating lasers in the MEMS projector, the horizontal positions of dots constituting a projected image can be altered at different horizontal scan lines. By increasing the number of scan lines corresponding to one 3D pixel, the number of views can be increased. Because the module has a frameless screen, a number of modules can be arranged two-dimensionally to obtain a large screen. The prototype module was constructed using four MEMS projectors. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
