Abstract: A display substrate and an electronic apparatus are provided. The display substrate includes a base substrate, and a dielectric layer, a first and a second electrode layer and a pixel defining layer thereon. The first electrode layer includes a first electrode and a second electrode spaced with a gap. The dielectric layer includes a first groove exposed by the gap; the second electrode layer includes a concave structure corresponding to the first groove; the pixel defining layer covers the first groove to form a second groove; within a cross section of the substrate, the concave structure includes a first and a second concave point, and a distance between the first concave point and the second concave point is less than a length of a portion, which is on a side of a first side surface of the second groove close to the first electrode, of the pixel defining portion.

Abstract: An LLC resonant conversion circuit includes a plurality of harmonic circuits. In each harmonic circuit, a plurality of transformers are electrically connected to each other and are electrically connected to one transformer in another harmonic circuit, so that the harmonic circuits are connected in a crossed manner. In this way, current or voltage of an electrical signal in one harmonic circuit can be distributed to another harmonic circuit. Without adding any component, this achieves the same current value for electrical signals in the harmonic circuits when the harmonic circuits are connected in parallel, and achieves the same voltage value for electrical signals in the harmonic circuits when the harmonic circuits are connected in series. This effectively reduces complexity of a control policy for the entire LLC resonant conversion circuit and also reduces costs of the LLC resonant conversion circuit.

Abstract: The power distribution system includes a plug-in frame, a board located in the plug-in frame, and at least one circuit breaker. The board includes a plurality of slot positions, a position signal acquisition apparatus is disposed on the board, and the position signal acquisition apparatus is configured to acquire an address of any slot position on the board.

Abstract: A search request transmitted by a first mobile terminal may be received. The search request may carry location information of the first mobile terminal, when the first mobile terminal transmits the search request. A corresponding grid number may be obtained, based on the location information. The grid number is configured to identify a preset longitude and latitude range of the earth sphere. Information searching for may be obtained based on the grid number. Information searched out may be transmitted to the first mobile terminal.
