Liquid crystal display device. |
| 摘要 |
<p>By a suitable choice of a retardation foil with a specific value of DELTA n ( lambda ) it is possible to make the transmission/voltage characteristic curves for, for example, red, green and blue light extend parallel in an ECB display. The same type of display can then be used for modulating three colours, with modulation voltages shifted for each colour.</p> |
