title: Multi-view display module employing MEMS projector array.
abstract: A frameless multi-view display module that consists of an array of microelectromechanical system (MEMS) based projectors, a sparse lenticular lens, and a vertical diffuser is proposed to provide a large-screen autostereoscopic display. The projectors are positioned in a horizontal vector form or in a matrix form in front of the transfer screen in order to produce the same number of three-dimensional (3D) pixels in each cylindrical lens constituting the lenticular lens to increase the horizontal resolution of the module. The projectors generate a slanted two-dimensional array of dots on the vertical diffuser to provide a large number of viewpoints. The experimental display system was constructed using four projectors. The system had a 3D resolution of 160 × 120, and it provided 64 views. The screen size was 14.4 in.
