4 results about "Disclination" patented technology

The invention relates to a method for reducing disclinations in an autostereoscopic display device that is electrically switchable between a 2D view mode and a 3D view mode, wherein the method comprises varying the angle between two directions of liquid crystal alignment in the lenticular device, to thereby determine an angle that causes a minimal or an acceptable occurrence of disclinations after switching between both view modes. The invention further relates to an autostereoscopic display device that exhibits reduced disclinations when switching between both view modes.

The application discloses a method for preparing three-dimensional micro-nano structure along disclination line of liquid crystal polymer surface, which comprises the following steps: S1, setting a filling area of a liquid crystal cell; S2, performing light-controlled orientation on the liquid crystal cell; S3, filling a liquid crystal mixture into the filling area, and performing photopolymerization on the liquid crystal mixture to form a thin film of liquid crystal polymer; disassembling the liquid crystal cell, and increasing the height of the filling area; S4, heating the thin film of liquid crystal polymer, and then placing the thin film in an electric field to form a three-dimensional micro-nano structure. The application aims at overcoming the shortcomings of the existing preparation method of micro-nano structure, and proposes a method for preparing regular surface three-dimensional micro-nano structure from bottom to top. In particular, the application can control the structure according to the design of a substrate orientation layer, so that regular or complex surface topography can be prepared.
