Abstract
The portable electronic products become more and more popular, because people can use these products for Video Entertainment and Business everywhere. The consumers can only receive the information from display images themselves. To share the image, they have to set up another projection device. This thesis proposes dual-mode projection display system to solve the aforementioned issue. This thesis will discuss the design of pico-projector applied in dual-mode projection display system. There are two parts in the design of pico-projector, one part of illumination use the non-sequential optical software for optimization. The other is the design of projection lenses. And then integrate the front projection and rear projection into dual-mode projection display system. This thesis will propose two methods to achieve dual-mode projection display, and discuss them respectively.
