Abstract

A display system and method are provided that enable two-dimensional and/or three-dimensional images to be displayed. One or more light manipulating layers, a pixel array, and an optional backlighting panel are provided. Each light manipulating layer may be a parallax barrier or a lenticular lens. A parallax barrier includes a plurality of barrier elements arranged in a barrier element array. The barrier element array includes a plurality of strips of barrier elements selected to be transparent to form a plurality of non-blocking strips. A lenticular lens includes an array of sub-lenses, and may be elastic. The display system is configured to deliver light from the pixel array or backlighting panel as views to corresponding viewers in a viewing space. The delivered views may include one or more two-dimensional views and/or one or more three-dimensional views.
