摘要： A method (200) and an apparatus (500) for compensating for brightness of a display panel (140), and a display device (100) are provided. The method (200) for compensating for brightness of a display panel (140) includes: timing a vertical blanking interval (Vblank) in a current frame on the display panel (140) (202); and determining, in response to that a timing time of the vertical blanking interval (Vblank) reaches a first threshold time, a first value used to perform first compensation on brightness of the display panel (140) during the vertical blanking interval (Vblank) in the current frame (204). According to the method (200) for compensating for brightness of a display panel (140), a brightness change caused by current leakage can be compensated for by adjusting a related analog voltage in a timely manner. Therefore, there is no delay between brightness compensation and current leakage, to resolve picture flickering and improve user experience of the display panel (140).

摘要： Embodiments of the present invention relate to a method and an apparatus for sending a packet. The method for sending a packet includes: determining whether a packet is a fragmented packet; if the packet is a fragmented packet, determining whether the number of tokens in a token bucket is sufficient; sending the fragmented packet, and deducting the number of tokens in the token bucket, where the deducted number of tokens corresponds to the number of bytes of the sent fragmented packet; and when the number of tokens in the token bucket is insufficient, the number of tokens in the token bucket is a negative number after the number of tokens corresponding to the number of bytes of the sent fragmented packet is deducted. The method and apparatus for sending a packet that are provided in the embodiments of the present invention, even if tokens in a token bucket are insufficient, can send out the fragmented packet by using a deficit of the token bucket, so that a receiving party is capable of receiving all fragmented packets belonging to the same packet and assemble all the fragmented packets into one complete packet, thereby avoiding waste of network resources and bandwidths.

摘要： A method for processing a fault of a lock server in a distributed system is disclosed, where the distributed system includes m lock servers, each lock server locally stores same lock server takeover relationship information, and m is a natural number greater than 2. Lock servers in the distributed system that are not faulty receive a first notification message, where the first notification message carries information about a fault of a first lock server; after receiving the first notification message, a second lock server in the distributed system determines that the second lock server is a takeover lock server of the first lock server according to locally stored lock server takeover relationship information, and the takeover lock server enters a silent state; after receiving the first notification message, a third lock server in the distributed system determines that the third lock server is not the takeover lock server of the first lock server according to locally stored lock server takeover relationship information; and after receiving a locking request, the third lock server allocates lock permission information according to the locking request. In the present invention, an affected range of a faulty lock server can be minimized and stability of a distributed system is enhanced.

摘要： Embodiments of this application provide a user interface UI interface adaptation constraint solving method and a related apparatus. In the method, a plurality of constraint relationships in a UI interface are identified and grouped into two types, a constraint relationship of a first type is solved in an integrated development environment IDE, and a constraint relationship of a second type is a constraint relationship solved in a terminal or the IDE. The plurality of constraint relationships are used to determine a layout of one or more components in the UI interface. The IDE calculates a first intermediate solution set based on the constraint relationship of the first type in the plurality of constraint relationships. The first intermediate solution set is used to determine the layout of the one or more components in the UI interface together with the constraint relationship of the second type. According to embodiments of this application, UI interface rendering efficiency of the terminal can be improved.
