Display panel using magnetically rotatable display elements

The display panel has a matrix of display elements (1), with at least two different colour display surfaces, rotated about parallel axes (9) by polarisation magnet discs (27) with two pole-pairs. The display elements are controlled in groups via a common setting and erasure electromagnet (6), cooper...

Beschreibung
Zusammenfassung:	The display panel has a matrix of display elements (1), with at least two different colour display surfaces, rotated about parallel axes (9) by polarisation magnet discs (27) with two pole-pairs. The display elements are controlled in groups via a common setting and erasure electromagnet (6), cooperating with the polarisation magnet discs. A pole surface comb (7) is fitted over the polarisation magnet discs for the display elements in a given matrix column or line, to provide a magnetic flux path between their opposing magnetic poles.
