Abstract: The present invention relates to a process for the stabilisation of a Liquid crystal (LC) mixture with negative dielectric anisotropy characterised in that one or more stabilisers of formula I Ra-A1-(Z1-A2)m1-Rb ??I in which Ra, Rb, A1, A2, Z1 and m1 have the meanings given in claim 1, are added to the LC mixture in a total amount of ?0.1% based on the total mixture, to an LC medium containing one or more stabilisers of formula I and to an LC display of the VA-, IPS or FFS type comprising said stabilised liquid crystal medium.

Abstract: The present invention relates to a liquid crystal (LC) display of the FFS type comprising a liquid crystal medium with negative dielectric anisotropy and a di- or multireactive polymerizable compound, and an alignment layer inducing planar alignment in the LC medium.

Abstract: Liquid-crystalline medium which comprises at least one compound of the formula I, in which R1 and R1* each, independently of one another, denote an alkyl or alkoxy radical having 1 to 15 C atoms, where, in addition, one or more CH2 groups in these radicals may each be replaced, independently of one another, by —C?C—, —CF2O—, —OCF2—, —CH?CH—, ?—O—, —CO—O—, —O—CO— in such a way that O atoms are not linked directly to one another, and in which, in addition, one or more H atoms may be replaced by halogen, L1 and L2 each, independently of one another, denote F, Cl, CF3 or CHF2, and the use thereof for an active-matrix display, in particular based on the VA, PSA, PA-VA, PS-VA, PALC, IPS, PS-IPS, FFS or PS-FFS effect.

Abstract: The present invention relates to a liquid crystal (LC) display of the FFS type comprising a liquid crystal medium with negative dielectric anisotropy and a di- or multireactive polymerizable compound, and an alignment layer inducing planar alignment in the LC medium.

Abstract: An apparatus and method in a tablet computer for disambiguating a handwriting input stream generated by a stylus-based user interface. A tablet application program interface (TAPI) of the present invention receives stroke data generated by a stroke made by a user on a digitizing tablet. The TAPI inserts the stroke data into a database. If the stroke is an editing gesture, the TAPI routes the stroke to a gesture recognizer which identifies an editing dialog. The TAPI then executes the dialog to perform operations on the database. If the application program is expecting text input, the TAPI continues to receive stroke data until it detects a closure event. The TAPI then forms a stroke group entry in the database by grouping all non-gesture stroke data received since the last closure event. The TAPI routes the stroke group data to a character recognizer, which returns candidate characters. The TAPI inserts the candidate characters into the stroke group entry.
