Method and device providing a liquid display
The present invention refers to a method for providing a liquid display displaying a selectable pattern (20-29, 45-48, 58-62) by selecting a pattern (20-29, 45-48, 58-62), emitting light rays (8) and light deflecting means (17-19, 39-43, 60-62) into said liquid stream (20-29, 45-48, 58-62) along its...

Zusammenfassung: | The present invention refers to a method for providing a liquid display displaying a selectable pattern (20-29, 45-48, 58-62) by selecting a pattern (20-29, 45-48, 58-62), emitting light rays (8) and light deflecting means (17-19, 39-43, 60-62) into said liquid stream (20-29, 45-48, 58-62) along its path and depending on the selected pattern (20-29, 45-48, 58-62) such that each light ray within the liquid stream (4, 35, 53) is guided by total reflection at the boundary of said liquid stream (4, 35, 53) until impacting a light deflecting means (17-19, 39-43, 60-62) by which the light ray is deflected in order to leave the liquid stream (4, 35, 53) as deflected light ray (11), with the deflected light rays (11) forming the selected pattern (20-29, 45-48, 58-62). It also refers to a device for providing such a liquid display. |
