The application provides a display substrate and a display device, wherein the display substrate comprises a substrate, a photosensitive circuit and a display circuit arranged on the substrate, wherein the photosensitive circuit comprises a photodiode and a first driving transistor coupled with the photodiode; the display circuit comprises a display device, a second driving transistor and a switch transistor coupled with the display device respectively; the distance between the corresponding gate layer and the active layer of the first driving transistor and the second driving transistor is greater than the distance between the corresponding gate layer and the active layer of the switch transistor. The display quality is improved.

This application provides a roof-mounted airbag and a vehicle. The roof-mounted airbag includes a shell, an air bag, a gas generator, and a guide tube. The air bag is disposed inside the shell; the gas generator is disposed outside the shell and the air bag; the guide tube connects the gas generator and the air bag to guide the gas generated by the gas generator to the air bag. This application enables an effective reduction in the thickness of the roof-mounted airbag without affecting its deployment performance.

The application discloses a mud plug ring machining method for a mud gun, and the mud plug ring machining method for the mud gun comprises the following steps: blanking, rough turning of an outer circle and an inner hole to obtain a ring-shaped workpiece, and machining of an opening on the workpiece; placing a gasket at the opening, and abutting two end faces of the workpiece at the opening with two side faces of the gasket respectively, then relatively fixing the gasket and the workpiece; finishing turning of the outer circle of the workpiece, then machining one end face of the workpiece to be flat; machining the other end face of the workpiece to be flat, then finishing machining of the inner hole of the workpiece; and finally recovering. The application solves the problem that in the prior art, the outer circle of the mud plug ring is continuously worn in the use process, the outer diameter of the mud plug ring becomes smaller, the opening gap of the mud plug ring and the mud bowl cooperation gap gradually increase, and the sealing performance of the mud bowl is affected.
