Method of driving a display device. |
摘要 |
<p>In the case of active drive of a ferro-electric liquid crystal display device the picture elements within the line selection period are first brought to an extreme state by means of a "blanking" signal. To obtain grey scales in a reproducible manner (via charge compensation) the data signal is preferably presented during a period which is short with respect to the switching period of the ferro-electric liquid crystal.</p> |
