The present application provides a splicing display device includes a liquid crystal display screen and an inorganic light emitting diode display screen. A color point coordinate of a color of a light emitted by the liquid crystal display screen in the CIE 1931 XYZ chromaticity diagram is in a first gamut triangle. A color point coordinate of a color of a light emitted by the inorganic light emitting diode display screen in the CIE 1931 XYZ chromaticity diagram is in a second gamut triangle. A gamut boundary of the second gamut triangle surrounds a gamut boundary of the first gamut triangle, and a difference between a NTSC color gamut corresponding to the second gamut triangle and a NTSC color gamut corresponding to the first gamut triangle is less than 30%.

Disclosed are a fluidized bed separation method and device for methanol-to-olefins quenched water. The method may subject quenched water to liquid-solid separation via a micro-cyclone separator. The method may also subject clear liquid from the micro-cyclone separator to a secondary separation via a fluidized bed separator, then sending the same to an olefin separation device, then recovering some waste heat of the quenched water, and then returning the same to a quenching tower after performing heat exchange. The method may also regenerate a separation medium by reversely feeding stripping tower purified water or quenched water, so as to release catalyst particles absorbed by the separation medium. The method may also send a catalyst slurry concentrated by the micro-cyclone separator and the fluidized bed separator to a filter-press unit for filter-press dehydration, so as to recover a catalyst.

A light board includes a light-emitting unit array including a plurality of light-emitting units arranged in an array and a driver backplane disposed on a backlight side of the light-emitting unit array. The driver backplane includes a base, a trace layer, and an insulating protection layer stacked successively in a direction away from the light-emitting unit array. The trace layer includes a plurality of traces and one or more bonding terminals each electrically connected to one of the traces. An orthographic projection of the insulating protection layer on the base overlaps the traces. The insulating protection layer includes one or more first opening each exposing one of the bonding terminals. The insulating protection layer is disposed on an outermost side of the side of the driver backplane away from the light-emitting unit array.

Disclosed is absorbable bone wax and a preparation method thereof. The preparation method comprises the steps of: 1) mixing polyoxypropylene polyoxyethylene block copolymer (PEG-PPG-PEG) and polyoxypropylene polyoxyethylene random copolymer (PEG-PPG), and stirring evenly under heating to obtain a liquid mixture; 2) under mechanical stirring and heating condition, adding hemostatic starch microspheres to the liquid mixture obtained in step 1) to obtain a uniformly-mixed liquid; and 3) adding a bone repair material to the uniformly-mixed liquid obtained in step 2), and mixing uniformly to obtain a mixed solution, then pouring the mixed solution into a mold or sub-packaged bottle, and leaving at room temperature for solidifying and shaping to give the absorbable bone wax. The absorbable bone wax of the present invention can achieve the effect of rapid hemostasis, changing the relatively single hemostasis method with traditional bone wax which only depends on physical sealing.
