Abstract: A display panel and a display module are provided. The display panel includes a non-display area, a central display area, and a peripheral display area arranged between the two areas. A counterpart substrate is arranged opposite to an array substrate, with a liquid crystal layer positioned between the array substrate and the counterpart substrate. A meta-surface structure layer of the counterpart substrate is arranged in the peripheral display area. Light emitted from the peripheral display area is at least partially deflected by the meta-surface structure layer and then emerges from the non-display area. The meta-surface structure layer in the peripheral display area alters the propagation path of light, allowing at least part of the light emitted from the peripheral display area to enter the non-display area. This approach overcomes the limitations imposed by a frame, enlarges the display area of the display panel, and achieves a narrow-frame display panel.

Abstract: A transmission assembly for a pump head of a six-cylinder opposed balanced diaphragm booster pump, a pump head of a diaphragm booster pump, and a diaphragm booster pump. The transmission assembly includes an eccentric assembly, a balance wheel assembly, a bearing and swing arms fixed to the balance wheel assembly. The eccentric assembly includes a motor shaft and eccentric wheels, wherein the movement of two eccentric wheels with a phase difference of 180° drives balance wheels of the balance wheel assembly to move oppositely. The eccentric assembly includes a first eccentric wheel, a second eccentric wheel and a third eccentric wheel in sequence, wherein the first eccentric wheel and the third eccentric wheel are similarly eccentric, and the second eccentric wheel is eccentric in an opposite manner to the first eccentric wheel and the third eccentric. The embodiments reduce noise caused by vibration of an existing diaphragm pump in operation.

Abstract: The present invention relates to a magnesium alloy material, which is an in situ magnesium hydroxide nanosheet layer modified magnesium alloy. The material is prepared from a magnesium alloy through a hydrothermal reaction under alkaline condition. The protective effect of the in situ formed magnesium hydroxide nanosheet layer structure results in remarkably enhanced corrosion resistance of the magnesium alloy, meanwhile the biocompatibility can also be significantly improved since the release rate of magnesium ion can be significantly reduced. In addition, the two-dimensional nanolayer structure has a non-releasing physical antibacterial property depending on contact. Therefore, the magnesium alloy material according to the present invention has an extremely great application prospect in the field of medical implant.
