The utility model provides a kind of for chip detection's fixed unit and fixing device, the fixed unit is three-layer structure, including tray, array card slot disc and cover plate sequentially matched from bottom to top;The tray is frame structure, the frame is formed with the limiting area for placing array card slot disc;Array card slot disc is equipped with the card slot position for limiting and fixing chip arranged in array;The cover plate is used to cover on array card slot disc, and its formed with through-hole array structure.The fixed unit and fixing device structure exquisite, light in weight, low in cost, not only can realize the simultaneous fixation to multiple different size chips, also can obviously improve fixing efficiency, reduce pollution and the risk of chip drop.

The application relates to a display substrate, comprising a display area and a frame area located around the display area, the display area comprising a plurality of data lines and a plurality of gate lines, and a pixel area defined by the intersection of the plurality of data lines and the plurality of gate lines, along a first direction, the frame area comprising a test area located on one side of the display area, the test area comprising at least one row of a plurality of first test electrodes and a plurality of second test electrodes arranged side by side; the test area further comprising a plurality of test transistors, one of the test transistors being connected with three of the first test electrodes; and a plurality of the second test electrodes being connected with the data lines through signal lines. The application further relates to a display device and a test equipment.

The invention discloses an Ethernet equipment position automatic identification method and device, equipment and a medium, and relates to the technical field of communication, and the method comprises the steps that processing equipment is connected with first equipment, second equipment, third equipment and fourth equipment through network cables, and distributes IP addresses to the first equipment, the second equipment, the third equipment and the fourth equipment, if the first device, the second device, the third device and the fourth device are determined to be communicated, running a test program to test the Ethernet throughput of the first device, the second device, the third device and the fourth device to obtain a test result, and judging whether a target device with the Ethernet throughput smaller than an Ethernet throughput threshold exists according to the test result; if yes, the Ethernet throughput of the physical interface of the target equipment is adjusted, and if not, normal information is fed back, and the test is continued. According to the method, simultaneous testing of a plurality of Ethernet devices can be realized, the positions of the Ethernet devices are automatically identified, and the testing efficiency is improved.
