Abstract: The present invention provides a manufacture method of a nano-imprint lithography template and a nano-imprint lithography template. In the manufacture method of the nano-imprint lithography template, first, the soft membrane having a nanowire gate structure is wrapped on the outer circumferential surface of the cylindric hard roller to form the nanowire gate structure film layer to obtain the temporary roller. Then, the low melting point solder alloy is utilized to form the structure hardened layer on the outer circumferential surface of the temporary roller along the nanowire gate structure of the nanowire gate structure film layer to obtain the nano-imprint lithography template having the nanowire gate structure. By forming the hard structure hardened layer on the soft nanowire gate structure for hardening the soft nanowire gate structure, the issue that the hardness of the micro structure material itself in the imprint procedure is not enough is overcame.

Abstract: A method of manufacturing a nano metal grating is provided. In the method, a patterned metal oxide film is formed on a surface of the metal layer through the formation of metal oxides in an oxygen ashing process, and the nano metal grating is manufactured by using the patterned metal oxide film as a mask. Thus, a drawback that the metal layer cannot be etched after the metal layer is oxidized is solved, and the metal oxide film is not only used as a mask to manufacture the nano metal grating, but the metal oxide film is also used as a protective layer of the nano metal grating.

Abstract: Disclosed are a driving method and a driving system for reducing a residual image of AMOLED display. The driving method includes steps of: determining whether an image to be displayed is a static image; performing hierarchical segmentation on the static image if a determination result is yes; regulating an output brightness proportional coefficient of each pixel based on a hierarchical segmentation result; and outputting brightness of each pixel according to a corresponding output brightness proportional coefficient. The driving method can significantly reduce generation of a residual image when a static image is displayed.

Abstract: Disclosed is a naked-eye three-dimensional display device, which is from top to bottom sequentially provided with a first substrate, a light-emitting layer, a second substrate, a first indium tin oxide (ITO) electrode layer, a three-dimensional prism liquid crystal layer, a second ITO electrode layer and a third substrate. One side of the first substrate facing the light-emitting layer is provided with thin film transistors arranged in a matrix form. Since the first ITO electrode layer is disposed directly on the second substrate, a substrate and a transparent photoresist layer are not used. Thus, the weight of the device is reduced, and the display brightness and the alignment accuracy are improved. When liquid crystal prism electrode units of the first ITO electrode layer and display regions of pixel units are configured to overlap with each other, the influence of transmitted light on naked eye 3D display can be avoided and the 3D display effect is improved.
