Abstract: Disclosed are a display apparatus and a display method therefor. The display method includes: a frame of to-be-displayed image data is received; the frame of to-be-displayed image data is segmented into N frames of sub-image data corresponding to the N display panels in a one-to-one correspondence; for each display panel, an initial peak brightness parameter corresponding to the display panel is calculated according to the sub-image data corresponding to the display panel; for each display panel, a target peak brightness parameter corresponding to the display panel is calculated according to the initial peak brightness parameter corresponding to the display panel and an initial peak brightness parameter corresponding to an adjacent display panel; and display is performed by each display panel according to the sub-image data and the target peak brightness parameter corresponding to the display panel.

Abstract: Provided are a preparation method for a propylene epoxidation catalyst, and a use thereof. During the preparation, an alkoxide solution of a prepared active component and a silica gel support are mixed, then a rotary evaporation treatment is performed on the mixture to remove a low-carbon alcohol to obtain a catalyst precursor, and then the obtained catalyst precursor is subjected to calcination and silylation treatments to obtain the propylene epoxidation catalyst. The catalyst is prepared in a simple process, can be applied to the chemical process of preparing propylene oxide by propylene epoxidation, has high average selectivity to propylene oxide, and has industrial application prospect.

Abstract: A hairbrush includes a bristle carrier including a surface and a plurality of first and second bristles fastened on the surface. The first bristles and the second bristles are arranged in rows and have a plurality of different configurations. In one embodiment, a bent member is formed on a top of each second bristle.

Abstract: A hair clip includes a curvilinear upper clamping arm having a shape as a curved knurled member; a curvilinear lower clamping arm having a slightly curved bend up shape; and a hinge assembly, said upper clamping arm including two side ears and elongated projections on an lower surface, said lower clamping arm including two side brackets, an elongated opening extending from a position adjacent of the other end to the side brackets to allow the plurality of elongated projections to pass through, protrusions disposed on an upper surface at either side of the opening, and said hinge assembly including a torsion spring and pins through the side ears and the brackets. The upper clamping arm and the lower clamping arm are set in a curved shape, the middle parts of the upper and lower clamping arms do not abut against each other to increase a large space for accommodating hair.

Abstract: An improvement of hair brush structure includes a brush head, a handle, and an adjustment device interconnected to the brush head and the handle. A repeated rotation of the adjustment device causes changing an appearance of the hair brush.

Abstract: A hair-drying comb and a combined comb are provided. The combined comb includes a comb plate, a handle, and at least two hair-drying combs. The comb plate is integrated with the handle, and the hair-drying combs are arranged on the comb plate at intervals along a width direction of the comb plate. Specifically, the hair-drying comb includes a comb body and a plurality of teeth. The comb body is C-shaped and opened with a C-shaped groove with a plurality of teeth disposed, the teeth are arranged at intervals along a length direction of the comb body, and both sides of each tooth are respectively provided with an absorbent strip. Due to the absorbent strips, while the hair-drying comb combs hair, the absorbent strips absorbs most of the water, and the combined comb can contact the hair more, comb the hair faster and absorb the water from the hair faster.

Abstract: A massage comb includes a comb body, a handle, a plurality of teeth, and a rolling bead. The handle is disposed below the comb body and integrated with the comb body, the plurality of teeth are arranged on the comb body at intervals, and the rolling bead is rollably disposed at the end of the handle. Since the massage comb is provided with rolling bead at the end of the handle, before or after combing the hair, the rolling bead can be used to massage the acupuncture points in the head, which facilitates opening the head meridian and enhancing blood circulation in the head. In addition, the rolling bead is arranged at the end of the handle, so that the massage comb of the present invention has a dual-purpose effect.

Abstract: A ventilating hairbrush includes a head body; a handle attached to the head body; and a plurality of bristles extending outwardly from the head body. The head body and the handle are formed integrally. The head body is cylindrical, elongated and includes a groove lengthwise disposed on a surface; and a plurality of spaced holes lengthwise disposed on the surface. The bristles are fastened in the holes.

Abstract: A hair curling device includes a hair curling mechanism including two pivot holes on left and right sides respectively; and a covering plate including two pivots on left and right sides respectively, the pivots being configured to insert into the pivot holes so as to pivotally secure the covering plate to the hair curling mechanism. The covering plate is configured to close or open the hair curling mechanism. When the covering plate is completely open, the hair curling mechanism is not covered by said covering plate.
