An optically active structure and a display device are presented. The device utilized an optically active structure comprising liquid crystal material and a plurality of nanorods configured to emit light in one or more predetermined ranges in response to pumping light. Variation in orientation of the liquid crystal varies orientation of the nanorods and modulated light emission therefrom.

LC-based optical display system

The present invention relates to light-converting materials which comprise semiconductor nanoparticles and an unactivated crystalline material, where the semiconductor nanoparticles are located on the surface of the unactivated crystalline material. The present invention furthermore relates to the use of the light-converting material in a light source. The present invention furthermore relates to a light-converting mixture, to a light source, to a lighting unit which contains the light-converting material according to the invention, and to a process for the production of the light source.

Light-converting material

The present invention relates inter alia to a color display comprising nanoparticles and color filters.

Semiconducting particles in electronic elements

The invention relates to compensation films for liquid-crystal displays with additions of rod-shaped liquid crystals mentioned below, to polarizer plates which have at least one compensation film of this type, to liquid-crystal displays which have compensation films of the said type, and to processes for the production of the said compensation films, polarizer plates and liquid-crystal displays, to the use of the compounds described in greater detail below as additions to compensation films for liquid-crystal displays, and to further subject-matters of the invention which can be seen below.

Optical compensation films

Disclosed are novel liquid-crystal compounds, processes and intermediates for the preparation thereof, the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays, and to LC media and LC displays containing the same.

Liquid-crystal compounds and LC media

The invention relates to a matrix liquid crystal display containing integrated non-linear elements and a liquid crystal mixture which has a particularly high resistivity.

Matrix liquid crystal display

Novel phenylcyclohexanes of the formula I in which n is 0 to 7, Qand Qare H, or one of these radicals is alternatively CH, r is 0, 1, 2, 3, 4 or 5, A is trans-1,4-cyclohexylene, 1,4-phenylene, 3-fluoro-1,4-phenylene or a single bond, X is F, Cl, &#x2014;CF, &#x2014;CN, &#x2014;OCFor &#x2014;OCHF, and Y and Z are each, independently of one another, H or F, with the proviso that, in the case where A is a single bond, Q=Q=H and simultaneously X=CN, Y and/or Z are F.

Phenylcyclohexanes and a liquid-crystalline medium

Described are matrix liquid crystal displays having two plane parallel support plates which together with a frame form a cell, integrated non-linear elements for switching individual picture elements on the support plates and a nematic liquid crystal mixture which is present in the cell and has a positive dielectric anisotropy and high resistivity. The liquid crystal mixture has a nematic phase range of at least 60&#xb0; C., a maximum viscosity at 20&#xb0; C. of 30 mPa&#xb7;s and a mean dielectricity constant &#x3b5;&#x2266;8. The liquid crystal mixture contains: a) at least 10% by weight of a liquid-crystalline component B having one or more compounds of the following formulae: and b) up to 90% by weight of a liquid-crystalline component A having one or more compounds with a dielectric anisotropy of &#x2212;1.5 to 1.5 of the formula I: 

The present invention relates to liquid-crystal mixtures having specific resistance values, comprising acidic compounds. The present invention furthermore relates to liquid-crystal displays containing these liquid-crystal mixtures. The invention furthermore relates to compounds of the formula I, in which the parameters are as defined in the text, to their preparation, and to their use for achieving certain specific resistance values in liquid-crystal mixtures. The application also relates to a method of adjusting the specific resistance of liquid-crystal mixtures using acidic compounds.
