| 摘要 |
An information display device including, as main components, a thermosensitive material layer which can be gradually converted between a completely opaque state and a completely transparent state under the influence of temperature, an electrode matrix, a control device for multiplexing, scanning or pulsating control signals to the individually addressable electrodes, possibly together with a colored backing layer. The electrodes in the matrix are connected via heating means at the electrode crossing points. At each crossing point there is further positioned a current valve means (diode) or a separate driver circuit for each heating means.
