Embodiment Construction

[0018] The present invention is illustrated below with the following examples. The present invention is not limited to these several examples.

[0019] Preparation of the liquid crystal cell: 2.0wt% polyvinyl alcohol aqueous solution was used to coat the conductive surface of the ITO glass by spin coating, baked at 80° C. for 30 minutes, and then rubbed and oriented in one direction with flannelette. Put the conductive surfaces of two well-oriented glass sheets facing each other, and place them anti-parallel along the rubbing direction, use a spacer with a thickness of 20.0±1.0um to control the thickness of the liquid crystal cell, and glue the edges with glue to make a parallel-oriented liquid crystal cell .

Abstract

The invention provides a production method for an electric field controlled wide wave reflection liquid crystal round polaroid, which belongs to the technical field of functional material liquid crystal display. By enabling one-dimensional nano materials and cholesteric liquid crystal to be mixed and poured into a liquid crystal box or a thin membrane, the method exerts different electric fields to control reflection wave width. The method has the advantages of being simple in composition and process, reflection wave width of the polaroid can be controlled through electric fields according to actual needs, and reversible control also can be achieved. The method can be applied to functional thin membranes and devices such as intelligent glass, electronic paper, liquid crystal display light incremental membranes and the like.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display of functional materials, and provides a method for manufacturing a liquid crystal circular polarizer capable of controlling wide-wave reflection by an electric field, and uses a nanoparticle cholesteric liquid crystal composite system to realize the manufacture of a liquid crystal circular polarizer with wide-wave reflection. Background technique [0002] Due to its unique optical properties, polarizers are widely used in display devices, transportation industry, national defense and cutting-edge science and technology. At present, the commonly used polarizers are mainly absorbing polarizers. Although these polarizers are cheap, they have many shortcomings and deficiencies, such as large optical loss, limited working environment, and fixed absorption bands of finished products that cannot be adjusted. Reflective polarizers that can be controlled by an electric field have broad appli...
