Flexoelectricity in a bimesogenic liquid crystal exhibiting the Ntb phase is higher than that in bimesogens without it. The N–Ntb interface shows a new periodic self-assembly pattern.

Samsung intends to be the world leader in LCD-TV through a combination of superior product technology, advanced process execution, and aggressive capitalization. This paper explores and updates Samsung's latest developments toward its goal of ultimate LCD-TV performance and market leadership. Samsung's development of Super PVA (S-PVA) represents a key performance achievement. S-PVA is a new technology which enables screen quality advantages over S-IPS and MVA, including high transmittance, >1000:1 contrast ratio, and wide angle of view with no off-axis image inversion. This new technology is described in detail. This paper also addresses the other remaining performance issues facing LCD-TV, including Samsung's plans for addressing these challenges. Until recently, inter-gray response time and associated motion blur were significant issues for achieving quality LCD-TV images. Samsung has invented DCC-II technology to achieve sub-10-msec response time, and this achievement is described. Other technology advancements, including next-generation color performance and ultra-low black performance, are discussed. Samsung has announced the development of a 57-in. full-HD (1920 × 1080) LCD-TV panel, the world's largest, based on S-PVA technology. This product represents the culmination of many technical breakthroughs, and is discussed herein. Samsung's LCD manufacturing strategy, which includes the world's first generation 7 LCD fab, is also described.

The direct observation of the domain size and defect distribution in a graphene film is important for the development of electronic applications involving graphene. Here we report a promising method for observing graphene domains grown by chemical vapour deposition. The unavoidable development of crack or pinhole defects during the growth and transfer processes is visualized using a liquid crystal layer. Liquid crystal molecules align anisotropically with respect to the graphene domains and exhibit distinct birefringence properties that can be used to image the graphene domains. This approach is useful for visualizing the crack distributions and their generation process in graphene films under external strain. This type of simple observation method provides an effective route to evaluating the quality and reliability of graphene sheets for use in various electronic devices.
