20090135360 | Liquid crystal display device - A liquid crystal display device includes a liquid crystal layer, a common electrode, and an electrode set. The liquid crystal layer is placed between said common electrode and the electrode set, and the electrode set is provided for switching the liquid crystal layer. The electrode set includes a first electrode for switching a first area of the. liquid crystal layer and a second electrode for switching a second area of the liquid crystal layer. Particularly, the second area includes at least a part of the area of the liquid crystal layer that the first area does not include. The first electrode has a shape which in cooperation with the second electrode allows alignment of the LC molecules in substantially two orthogonal directions. A method is provided to get rid of the circular polarizers which provide a good on-axis aperture but which show reduced off-axis performance compared to linear polarizers. | 05-28-2009 |
20090167995 | LCD WITH IMPROVED CONTRAST RATIO AND APPARATUS UTILIZING THE SAME - An LCD device with an LCD cell. The cell has a liquid crystal layer, a base panel adjacent to the liquid crystal layer and a top panel adjacent to the liquid crystal layer but opposing the base panel. The base panel has a first polarizer arranged to polarize incident light into a first direction. The top panel has a color filter with one or more color filter portions so as to produce light with a predetermined color, a second polarizer on a side of the color filter opposite to the liquid crystal layer and designed to polarize incident light into a second direction perpendicular to the first direction, and a third polarizer located between the color filter and the liquid crystal layer and designed to polarize incident light into the second direction. | 07-02-2009 |
20090174853 | ELECTRODE STRUCTURE FOR AN LCD DEVICE - A liquid crystal display device has pixels, and each pixel has a lower substrate and an upper substrate with a liquid crystal material in between. The each pixel also has an electrode structure between the lower substrate and the upper substrate. The electrode structure has electrodes, and each electrode has a polygon-shaped electrode surface and a plurality of electrode edges. The electrodes are arranged such that if an electrode edge is facing an electrode edge of an adjacent electrode then the electrode edge and the electrode edge of the adjacent electrode define a distance which is substantially constant along the entire electrode edge. | 07-09-2009 |
