Abstract: An optical module unlocking apparatus includes: a base, a sliding member, a driving piece, and an elastic piece. The sliding member is slidably disposed on the base along an insertion direction. The driving piece is rotatably connected to the base, the other end of the sliding member is connected to the driving piece, and the driving piece can rotate from a locked state to an unlocked state relative to the base under an action of external force, and drive the sliding member to move relative to the base along the insertion direction. A second connecting part is disposed on the driving piece. Because the driving piece is located outside a cage, space for disposing the elastic piece on the driving piece is sufficient, and the driving piece does not need to fit a spring plate. This simplifies a structure of the optical module and improves processing efficiency.

Abstract: A test circuit transmits input data of a test vector to a data distribution circuit using an input of a test bus, and transmits the input data of the test vector to a scan input channel in a circuit under test using the data distribution circuit. After scan of the circuit under test is completed, output data of the test vector on a scan output channel in the circuit under test is transmitted to an output of the test bus using the data distribution circuit, to complete testing of the circuit under test. A dynamic correspondence between the data distribution circuit and the test bus may be configured based on a specific test solution, so that a test resource can be dynamically allocated.

Abstract: A display method and an electronic device that relate to the field of terminal technologies are provided. A first electronic device can obtain identification information of a plurality of second electronic devices- and establish a correspondence between a display region of the first electronic device and identification information of each second electronic device. Therefore, the second electronic devices can automatically display content in different display regions based on the correspondence. The method includes performing, by the first electronic device, sending a display configuration message, receiving identification information sent by a second electronic device, establishing a correspondence between a display region and the identification information, and sending the correspondence and displayed display content. In this way, the second electronic device can determine, based on the correspondence, a part or all of display content that is in the received display content and that corresponds to the display region.

Abstract: A display picture synchronization method includes a source device that sends a first picture frame and a first specified display time corresponding to the first picture frame to each of the sink devices. If each of the sink devices successfully receives the first picture frame and determines that the first picture frame is capable of being displayed based on the first specified display time, each of the devices for performing picture frame synchronization display displays the first picture frame based on the first specified display time. Each of the devices for performing picture frame synchronization display does not display the first picture frame if a first sink device in the sink devices fails to receive the first picture frame or successfully receives the first picture frame but determines that the first picture frame is incapable of being displayed based on the first specified display time.

Abstract: This disclosure provides methods and apparatuses for testing a tested circuit. In an implementation, a chip test circuit transmits input data of a test vector to a data distribution circuit through an input of a test bus, and transmits the input data of the test vector to a scan input channel of a tested circuit through the data distribution circuit. After scanning of the tested circuit ends, output data of the test vector of the scan output channel of the tested circuit is transmitted to an output of the test bus through the data distribution circuit to complete the test of the tested circuit. A dynamic correspondence between the data distribution circuit and the test bus is implemented by configuring a first selector, so that test resources can be dynamically allocated.
