FAST TRANSITIONS OF LARGE AREA CHOLESTERIC DISPLAYS |
摘要 |
<p>A gray scale drive scheme for passive matrix displays, more specifically cholesteric liquid crystal displays. Prior to writing an image, the display can be given a black appearance by first driving the pixels to a homeotropic state, then driving the pixels to a focal conic state. The drive scheme then resets pixels by driving the selected pixels to a homeotropic state. Selecting and non-selecting row voltage signals are then used in combination with column voltage signals to write an image to the display.</p> |
