A liquid crystal display includes a display area and a border area at least partially surrounding the display area, where the display area displays images for viewing and the border area displays display-protection images, which are used to control ion migration in the liquid crystal layer. In a more particular embodiment, the border area displays a series of checkerboard pattern(s), where the checkerboard patterns can alternate between initial and inverted values. The display-protection images protect the liquid crystal display from migrating ions accumulating in particular regions of the pixel array and causing permanent defects in the display area. A liquid crystal display that includes a liquid crystal alignment layer having a plurality of liquid crystal alignment directions is also disclosed. The customized liquid crystal alignment director(s) over the border area promote ion migration away from the display area.

The method for orientation of liquid crystals in a micro/nano region on the basis of laser direct writing and a system thereof includes a laser direct writing system employed to build a micro/nano structure. Liquid crystal molecules in a micro/nano structural region perform self-orientation; and the orientation of liquid crystals is generated by fine structures on side walls of polymer strips which form the micro/nano structure. The dimension of the micro/nano region varies from the micrometer magnitude to the nanometer magnitude exceeding the diffraction limit. The orientating direction can be adjusted and controlled in the micro/nano region, which is favorable for the miniaturization of the liquid crystal display devices and the orientation of the complicated three-dimensional liquid crystal structure.
