Embodiments are disclosed that relate to fabrication of a laminated optical wedge. One embodiment provides a method comprising inserting a wedge blank into a vacuum molding tool, applying a vacuum to the vacuum molding tool, and removing a layer from a top surface of the wedge blank to expose a machined surface of the wedge blank. The method further comprises laminating a finish piece to the machined surface via an adhesive, wherein the finish piece comprises a smoother surface than the machined surface, and curing the adhesive to form a finished optical wedge. The method further comprises removing the finished optical wedge from the vacuum molding tool.

Embodiments are disclosed herein that relate to the front-projection of an interactive display. One disclosed embodiment provides an interactive display system comprising a projector and a display screen configured to display an image projected by the projector, the display screen comprising a retroreflective layer and a diffuser layer covering the retroreflective layer, the diffuser layer being configured to diffusely reflect only a portion of light incident on the diffuser layer from the projector such that another portion of light passes through the diffuser layer and is reflected by the retroreflective layer back through the diffuser layer. The interactive display system also comprises a camera configured to capture images of the display screen via light reflected by the retroreflective layer to identify via the images a user gesture performed between the projector and the display screen.
摘要:
An electrophoretic display has a matrix addressing structure which includes a first support structure 10 on one side of the display and a second support structure 20, substantially parallel to the said first support structure, on the other side of the display. On the inner surface 12 of the first support structure 10 there is a first set of parallel electrodes 11 and on the facing the inner surface 23 of the second support structure 20 there are second 22 and third 21 sets of parallel electrodes arranged substantially orthogonal to the first set of electrodes 11. The electrodes 21,22 of the second and third sets are interspersed with one another.
