Abstract: A heat dissipation assembly includes a heat dissipation layer main body including at least one first side, arc-shaped corner side and second side, at least one first bending portion, second bending portion and corner bending portion. A first side, an arc-shaped corner side and a second side are sequentially connected. A first bending portion, a corner bending portion and a second bending portion, that are sequentially connected, are respectively connected to the first side, the arc-shaped corner side and the second side; the corner bending portion is provided with at least one first opening therein. A first opening is in a shape of a strip, and extends substantially in a radial direction of the arc-shaped corner side. In a case where the corner bending portion is provided with first openings therein, the first openings are sequentially arranged at intervals in an extending direction of the arc-shaped corner side.

Abstract: A display module and a display device are disclosed. The display module includes a display substrate provided with a first edge; a circuit board arranged at the first edge of the display substrate and electrically connected with the display substrate; and a supporting plate arranged on the non-display surface of the display substrate; the supporting plate is able to be bent and includes a first part and a second part, and the second part is provided with a hollow opening; the display substrate is positioned on the first part and is fixedly connected with the first part; and the circuit board is positioned on the second part and is fixedly connected with the second part.

Abstract: Provided is a rotary shaft mechanism including a curved base, a screen support plate, a curved slider, and a rotating block; the curved base includes a first centerline extending along X direction and two curved connecting portions symmetrically arranged around the first centerline; in the X direction, the screen support plates are on opposite sides of the curved base, each curved connecting portion is connected to the corresponding screen support plate through the curved slider and the rotating block; along the X direction, each curved connecting portion is divided into first and second curved guide grooves, the rotating block includes a curved connector connected to the first curved guide groove, and a sliding connector slidably connected to the screen support plate; the curved slider is rotatably connected into the second curved guide groove, and the curved slider is rotatably connected to the screen support plate through a pin-shape shaft.

Abstract: This application relates to a method and an apparatus for controlling a sound receiving device based on a dual-mode audio three-dimensional code and a method and an apparatus for parsing a control signal of a sound receiving device based on a dual-mode audio three-dimensional code. The method includes: receiving an operation instruction and encoding the operation instruction as a digital vector; obtaining a first audio three-dimensional code corresponding to a preset speech signal, and encoding the digital vector into the first audio three-dimensional code to obtain a second audio three-dimensional code; and converting the second audio three-dimensional code into a speech signal and sending the speech signal to a sound receiving device. In the method, operation convenience can be improved, and an instruction operation can be performed without arrangement of any additional module.

Abstract: A negotiation method used in a high definition multimedia interface (HDMI) is provided. The negotiation method includes: transmitting a first negotiation signal from a first side to a second side during a first specific time period for enabling negotiation of an HDMI Ethernet Channel (HEC); and checking whether any negotiation signal sent from the second side is received by the first side for determining a result of the negotiation. The first negotiation signal includes parameters of Energy Efficient Ethernet (EEE) or parameters of flow control at least. Any packet of the negotiation signal excludes a data field of Start Frame Delimiter (SFD), and therefore the packet can be applied for point-to-point transmission and compatible with the Physical layer.
