Pixel-isolated liquid crystal mode for flexible display applications

We developed a new device using anisotropic phase separation from liquid crystals (LCs) and polymer composite materials using UV intensity variation and polymer wetting properties for flexible display applications. In the device, LC molecules are isolated in pixels where LCs are surrounded by interpixel vertical polymer walls and horizontal polymer films on the upper substrate. This device shows very good mechanical stability against external pressure. The electro-optic characteristics and the mechanical stability of the device are discussed in view of flexible display applications.
