187 | IN-PLANE SWITCHING ELECTROPHORETIC COLOUR DISPLAY | EP07849264.2 | 2007-11-27 | EP2122412A2 | 2009-11-25 | LENSSEN, Kars-Michiel H.; BAESJOU, Patrick J.; VAN DELDEN, Martinus, H. W. M.; ROOSENDAAL, Sander J.; STOFMEEL, Leon W. G.; VERSCHUEREN, Alwin R. M. |
In-plane switching type colour electrophoretic display. The electrophoretic layer consists of cavities (18ab) containing a suspension, which define the pixels (10, 12). Adjacent to each cavity, two control electrodes (20a, 20b) are arranged outside the field of view (26) of the pixel, to initiate in-plane motion of the particles. Two particle types (24a, 24b) differing in colour (yellow, cyan) and optionally: (i) particle mobility or threshold electrical field for initiating motion as well as (possibly charge polarity) or (ii) an additional control electrode also arranged outside the field of view, are arranged in a suspension in the pixel cell. This 'arrangement allows a composite colour scheme for each pixel to be obtained ^in a controllable way. The control electrodes may be arranged at the bounding ends of the cavity, i.e. normal to the layer plane, or in the layer plane at the edges of the cavity. Since they are also covered by a light shielding layer, the electrodes and the particles collected on them, do not impinge on the field of view of the pixel. In addition only a small part of the cavity area is covered by electrode material, so that the total transmission (brightness) of the pixel can be optimized. Two such cells (18ab, 18cd) may be stacked on top of each other. Particles in the second cell (yellow, cyan) have different colours than those in first cell (magenta, black), but their other properties are arranged according to option (i). One of the cells determines mainly the luminance of the display, the other its colour. A white reflector allows a reflective CMY or CMYK subtractive colour display to be achieved. A transmissive variant with a backlight is also disclosed. | ||||||

Die Träger sind mit transparenten Elektroden und Orientierungsschichten versehen, einem Raster-Linsenobjektiv, einer Ausgangsmaske mit Spalten, deren Lage mit der Lage der Spalten der Eingangsmaske abgestimmt ist. Die Fläche des Elements ist in drei Teilbereiche derart aufgeteilt, dass eine Phasen-Beugungsstruktur in der Schicht des Flüssigkristalls möglich ist. Die Orientierungsschichten sind dadurch gekennzeichnet, dass sie aus einem Fotopolymer bestehen und dass die Phasen-Beugungsstruktur durch die Bereiche des Flüssigkristalls mit unterschiedlicher Ausgangsorientierung gebildet ist, die durch eine unterschiedliche Richtung der Polarisationsebene bei der Belichtung des Fotopolymers bedingt ist. Die Periode der Bereiche mit verschiedener Orientierung ist in jedem der Teilbereiche gleich und die gegenseitige Spaltenlage der Ausgangsmaske ist bezüglich der Spalten der Eingangsmaske innerhalb jedes Teilbereichs unterschiedlich, wobei der Durchlass einer in jedem Teilbereich unterschiedlichen Farbe von drei primären Farben innerhalb jedes Teilbereichs gewährleistet ist. |

Es wird eine Farb-Flüssigkristallanzeigeeinrichtung angegeben, die eine verbesserte Auflösung besitzt. Die Farb-Flüssigkristallanzeigeeinrichtung umfasst eine erste und eine zweite cholesterische Flüssigkristallschicht (2, 10). Die erste Flüssigkristallschicht enthält nebeneinander angeordnete Grundfarbpixel (14) einer ersten und einer zweiten Grundfarbe (14-B, 14-G). Die zweite Flüssigkristallschicht enthält nebeneinander angeordnete Grundfarbpixel (14) der ersten und einer dritten Grundfarbe (14-B, 14-R). Die Grundfarbpixel der ersten Grundfarbe (14-B) in der ersten und zweiten Flüssigkristallschicht (2, 10) sind in Beobachtungsrichtung (8) hintereinander angeordnet. Die Grundfarbpixel der zweiten Grundfarbe (14-G) in der ersten Flüssigkristallschicht (2) und die Grundfarbpixel der dritten Grundfarbe (14-R) in der zweiten Flüssigkristallschicht (10) sind in Beobachtungsrichtung (8) hintereinander angeordnet. Jeweils zwei Grundfarbpixel der ersten Grundfarbe (14-B), die in der ersten und zweiten Flüssigkristallschicht (2, 10) hintereinander angeordnet sind, wirken mit dem benachbarten Grundfarbpixel der zweiten Grundfarbe (14-G) in der ersten Flüssigkristallschicht (2) und dem benachbarten Grundfarbpixel der dritten Grundfarbe (14-R) in der zweiten Flüssigkristallschicht (10) zur Darstellung eines Anzeigepixels (18-i) zusammen. Dadurch, dass zur Darstellung eines Anzeigepixels sowohl nebeneinander als auch hintereinander liegende Grundfarbpixel herangezogen werden, werden in einer Ebene bzw. in einer Flüssigkristallschicht nur die Flächen für zwei statt der üblichen drei Grundfarbpixel pro Anzeigepixel benötigt. Hierdurch ergibt sich die verbesserte Auflösung. Zusätzlich wird auch die Ablesbarkeit der Anzeige bei hellem Sonnenlicht oder in sonstiger heller Umgebung verbessert. |

200 | SWITCHABLE COLOR FILTER | EP01975958.8 | 2001-11-01 | EP1330677A1 | 2003-07-30 | FÜNFSCHILLING, Jürg; SCHMITT, Klaus; SCHADT, Martin |
The liquid crystal switchable color filter switches between three color bands and is preferably used for time-sequential color devices, as for example projection devices, direct view displays and video cameras. The color filter employs circularly polarizing selective reflection bands of at least four cholesteric filters (cfb1 cfr2) together with three liquid crystal switches (sw1, sw2, sw3) and related retarder layers. The handedness of the second cholesteric filter (cfg1) is equal to the handedness of the third cholesteric filter (cfg2) and opposite to the handedness of the first and fourth cholesteric filter (cfb2, cfr1), and for the blocking state of a color band the optic axis of the corresponding liquid crystal switch is parallel or perpendicular to the polarization direction. This concept leads to an improved, excellent color saturation and requires less stringent production tolerances than in the prior art. Moreover, it advantageously allows overlapping color transmission bands thus improving the light efficiency. |
