Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: A mirror display module including a first substrate, pixel units, a second substrate, a display medium layer, a reflection pattern, a third substrate, an electrochromic material layer, a first transparent electrode, and a second transparent electrode is provided. The pixel units are disposed on the first substrate. The second substrate is disposed opposite to the first substrate. The display medium layer is located between the first substrate and the second substrate. The reflection pattern is located between the second substrate and the display medium layer. The reflection pattern has a plurality of openings, and the plurality of openings is overlapped with at least a portion of the plurality of pixel units. The second substrate is located between the third substrate and the first substrate. The electrochromic material layer is located between the third substrate and the second substrate. The first transparent electrode is located between the third substrate and the electrochromic material layer.
