This utility model discloses a flexible suction port for a roving blowing and suction cleaning machine. Its structure includes a suction assembly, a suction port, and an adaptive adjustment mechanism. Through the contact of a roller assembly with the surface of the drafting cover plate, it senses changes in the height of the drafting cover plate in real time and drives the suction port to move along a vertical slide rail, dynamically maintaining a constant distance between the suction port and the drafting cover plate to ensure stable waste absorption. The adaptive adjustment mechanism adjusts the height of the roller support through a strip groove and bolts, and combines stackable weights to dynamically balance the roller contact pressure, adapting to different working conditions. This utility model adopts a modular design; the suction port is fixed by clamps for easy disassembly and maintenance; the weight and number of weights are adjustable, improving pressure control accuracy. Its significant advantages lie in automatically adapting to drafting cover plate deformation and track misalignment, reducing manual intervention, and improving cleaning efficiency by more than 60%. It is suitable for various roving frame equipment and has broad industrial application value.

A display device includes a substrate; a first electrode disposed on the substrate; a pixel definition layer having a pixel opening defined on the first electrode; an emission layer disposed in the pixel opening; a second electrode disposed on the emission layer; an encapsulation layer disposed on the second electrode; a sensing electrode portion and a reflective layer disposed on the encapsulation layer; a first light blocking layer overlapping the sensing electrode portion; and a second light blocking layer overlapping the reflective layer, wherein the reflective layer includes a plurality of recessed portions disposed in an area overlapping the second light blocking layer.
