20130148069 | LIQUID-CRYSTALLINE MEDIUM AND LIQUID-CRYSTAL DISPLAYS - The present invention relates to liquid-crystal media and liquid-crystal displays (LC displays) comprising these media with homeotropic (vertical) alignment of the liquid-crystalline medium (LC medium). The LC medium having positive dielectric anisotropy according to the invention comprises particles having a mass of at least 450 Da which have been functionalised by a polar, organic anchor group. It is preferably stabilised by a polymerisable component. | 06-13-2013 |
20130314655 | LIQUID-CRYSTAL DISPLAYS HAVING HOMEOTROPIC ALIGNMENT - The present invention relates to liquid-crystalline media (LC media) comprising self-aligning additives which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional imide alignment layers. The LC media are optionally supplemented by a polymerisable or polymerised component, which serves for stabilisation of the alignment, for adjustment of the tilt angle and/or as passivation layer. | 11-28-2013 |
20140138581 | LIQUID-CRYSTALLINE MEDIUM - The invention relates to a liquid-crystalline medium based on a mixture of polar compounds having a negative dielectric anisotropy which contains at least one self-aligning additive, especially at least one additive selected from the group of the compounds of the formula IA to ID | 05-22-2014 |
20150252265 | LIQUID-CRYSTALLINE MEDIA HAVING HOMEOTROPIC ALIGNMENT - The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy, comprising a low-molecular-weight component and a polymerizable component. The polymerizable component comprises self-aligning, polymerizable mesogens (polymerizable self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the LC medium without alignment layers. The invention discloses novel structures for self-alignment additives which have a certain position of the functional groups. | 09-10-2015 |
20150301368 | Liquid-crystal displays and liquid-crystalline media having homeotropic alignment - The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy comprising self-alignment additives (SAMs) with an at least one bifunctional or polyfunctional anchor group, which effects the homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional imide alignment layers. The LC media may be supplemented by a polymerizable or polymerized component, which serves for stabilisation of the alignment, for adjustment of the tilt angle and/or as passivation layer. | 10-22-2015 |
20150322342 | LIQUID-CRYSTALLINE MEDIUM - The invention relates to the compounds of the formula I and to a liquid-crystalline medium based on a mixture of polar compounds which contains at least one compound of the formula I | 11-12-2015 |
20160046863 | LIQUID-CRYSTALLINE MEDIUM - The invention relates to a liquid-crystalline medium based on a mixture of polar compounds which contains
