| 摘要 |
<p>The invention relates to a flat screen with light valves, which may be reflective or transmittive, consisting of cells comprising a transparent plane (100), a perpendicular electrode (102), two transparent conducting electrodes (104, 105), two flaps (103) which are situated symmetrically in relation to the electrode (102). Said flaps can turn by an angle that is less than or equal to 90°, by means of electrostatic forces, and rest against the plane of the electrodes (104, 105) or on the sides of the perpendicular electrode (102). The invention is suitable for display or projection screens.</p> |
