Abstract: The present invention discloses a display panel and a display device. The display panel includes a gate driver circuit and a plurality of driving wires. By disposing gate driver circuits with different distribution density in non-bending frame regions and adjusting corresponding driving wires wired from an output end of the gate driver circuit to a bending displaying region, normal driving of the bending displaying region can be achieved and simultaneously damages to the gate driver circuit during folding can be mitigated or obviated.

Abstract: A rotating shaft mechanism includes a body, a first door plate, a second door plate, an intermediate door plate, a first connecting rod assembly, and a second connecting rod assembly. The first connecting rod assembly includes a first housing connecting rod, a first gear connecting rod, and a first secondary connecting rod. The rotating shaft mechanism further includes a first meshing transmission structure. The first housing connecting rod, the first gear connecting rod, the first secondary connecting rod, the first door plate, and the body form a crank-slider structure to drive the first door plate to rotate relative to the body. The first gear connecting rod drives the intermediate door plate to move relative to the body using the first meshing transmission structure.

Abstract: This disclosure discloses a fish-passing system and a fish-passing method with tourist ornamental function, belonging to the technical field of water conservancy and hydropower ecological protection. The system comprises a dam, a Ferris wheel, a water supplement component, and a central controller. The upstream of the dam is equipped with a fish-release chute, and one end of the fish-release chute extends into the water body of the dam reservoir. The downstream of the dam is equipped with a fish passage transfer mechanism, and the fish passage transfer mechanism is connected to the downstream water body of the dam through a fish passage. The Ferris wheel is located between the fish passage transfer mechanism and the fish-release chute, and a number of fish-carrying and human-ascending mechanisms are evenly arranged on the Ferris wheel.

Abstract: A folding apparatus includes a principal axis, a first bracket and a second bracket that are located on two sides of a principal axis along a width direction. A first connecting rod and a second connecting rod are located on two sides of the principal axis along the width direction, and a first swing arm and a second swing arm are located on two sides of the principal axis along the width direction. A first support plate and a second support plate are located on two sides of the principal axis along the width direction. When the first bracket and the second bracket rotate to be positioned face-to-face, and a length of accommodating space of the folding apparatus that accommodates a folded part of a flexible display can be extended.

Abstract: A corner detection method includes: acquiring a dynamic vision sensor (DVS) event frame, the DVS event frame including at least one event and being pre-divided into a plurality of areas; determining, of the at least one event, a number of events in each of the plurality of areas; detecting corners in each of the plurality of areas based on the number of events in each of the plurality of areas and a preset maximum number of corners; and obtaining a plurality of corners of the DVS event frame based on the detected corners.
