Abstract

Magnetoforézisen alapuló képmegjelenítő berendezés (20), amelytartalmaz egy átlátszó előlapot (4), egy hátlapot (6), amely azelőlappal (4) illesztve légmentesen zárt teret (8) hoz létre, egyfelosztó elemet, amely az előlap (4) és a hátlap (6) által határoltlégmentesen zárt teret (8) nagyszámú cellára osztja fel, mágnesszemcséket tartalmazó cseppfolyós diszperziót (120, 12b, 12c, 14a,14b, 14c), amely légmentesen van felosztó elem által kialakítottcellákba zárva, egy mágneses íróeszközt, amely az előlap (4) külsőfelületén mozgatható, és meghatározott mágneses erővel rendelkezik,hogy 100-500 Gauss értékű tényleges mágneses fluxussűrűséget hozzonlétre a hátlap (6) külső felületén, amikor a mágneses íróeszköz azelőlap (4) külső felületével érintkezik, és egy mágneses törlőeszközt,amely a hátlap (6) külső felületén van elhelyezve, és meghatározottmágneses erővel rendelkezik, hogy 100-1500 Gauss értékű ténylegesmágneses fluxussűrűséget hozzon létre az előlap (4) külső felületén,amikor a mágneses törlőeszköz a hátlap (6) külső felületévelérintkezik. A berendezés felületén meghatározva a mágneses eszközöktényleges mágneses fluxussűrűségét, kiküszöbölhetik a képernyőnmegjelenő kép megtörését az egyes cellahatároknál, és tökéletesítik amegjelenített kép kontrasztját és felbontását.
