Abstract: We have developed a large-scale 3D (three-dimensional) display for outdoor applications like billboards, where the viewers are not required to wear any special glasses in order to perceive a 3D effect. Each display element?a so-called ��trixel��?contains three laser diodes, a common microlens, as well as a micro-electro-mechanical systems (MEMS) mirror. In this paper we present the latest prototype generation of our display, which is completely modular, i.e., an array of 12 x 9 trixels including all corresponding driver electronics is contained in a so-called ��trixel module��. A large number of such trixel modules can be arranged seamlessly, which imposes no upper limit in terms of the overall display size. The present prototype contains trixels with highly compact hermetically sealed RGB laser modules, where each module contains a red, a green, and a blue laser diode, a driver ASIC with integrated photodiodes, as well as the common cylindrical microlens. The trixel module will enable large 3D billboards with sunlight readable luminance, up to 1024 3D viewing zones, and a 3D viewing distance of up to 70 meters.
