Abstract: Disclosed is a dimming control circuit compatible with emergency lighting, and a method. The dimming control circuit includes a main control circuit; a first port circuit, where an input terminal of the first port circuit is electrically connected to an external automatic dimming circuit, and an output terminal of the first port circuit is electrically connected to a corresponding input terminal of the main control circuit; and a second port circuit.

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.

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: 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.
