DIRECT VIEW DISPLAY BASED ON LIGHT DIFFRACTION FROM A DEFORMABLE LAYER |
摘要 |
A direct view display device based on light reflection and diffraction from a deformable material layer under influence of an electric field. The display device comprises a plurality of pixel cells, each cell has at least a first prism surface to support the deformable material, such that when the electric field is off, a light beam travels through the first prism surface and the deformable material is reflected via total internal reflection through the first prism surface to a second prism surface, whereby the light beam is directed toward a beam blocker. When the electric field is on, the deformable material forms a rippled surface to diffract the encountering light beam, allowing part of the light beam to avoid the beam blocker. A microlens is used for each pixel cell to focus the light beam at the beam blocker. |
