Abstract: A switchable grating and an application thereof are provided. The switchable grating includes two electrically conductive substrates and a switchable liquid crystal grating layer, which is disposed between the two electrically conductive substrates. When an electric field is applied to a presumption area of the switchable liquid crystal grating layer by the two electrically conductive substrates, the electric field could shift an orientation of a cholesteric liquid crystal molecule of the presumption area. When the electric field is removed, the cholesteric liquid crystal molecule still maintains the aforementioned orientation, thus decreasing energy consumption. When a display device manufactured by the aforementioned switchable grating switches an image to a 2D image or a 3D image, the display device has lower energy consumption.

Abstract: The present invention relates to a sheet for mounting a workpiece and a method for making the same. The method includes the steps of: (a) providing a sheet body having a top surface, a bottom surface, at least one side surface and a plurality of pores, wherein some of the pores open at the side surface; and (b) sealing or narrowing the pores that open at the side surface. Since the pores that open at the side surface are sealed or narrowed, the slurry is prevented from entering into the interior of the sheet body. Therefore, the infiltration distance reaches a predetermined value slowly, thereby increasing the effective life of the sheet.
