A storage array, a memory, a reading method thereof, and an electronic device are disclosed. The storage array includes multiple storage cell subarrays, a reference cell column, and a set of reference voltage generation circuits, reference cell switching circuits, and read word line control circuits. The storage cell subarrays and reference cell column in two storage arrays are electrically connected via read bit lines and symmetrically distributed around a read decision unit. The transistors of the reference cells and storage cells are isomorphic and have the same circuit structure. The memory includes at least one pair of open storage arrays, each pair comprising a first storage array, a second storage array, and a set of read decision units. Each storage array is electrically connected to one of the two input terminals of the read decision unit. During reading, the two storage arrays provide a read voltage and a reference voltage, respectively. The two input terminals of the read decision unit have similar RC parameters, and the drift generated by the voltages at the two input terminals is also matched. This application improves storage density and data reading reliability.

The invention discloses a gate drive circuit, a display panel and a display device. A level transmission module is used for outputting a level transmission signal, and an output module is used for outputting a gate control signal. A first output unit of the output module is communicated with a current path between a first output end and a first power supply end according to a second clock signal in a first time period, the cascade transmission module receives a starting signal according to the first clock signal in a second time period, and the first time period and the second time period are at least partially overlapped; the level transmission signal is used for sharing the load corresponding to the output end outputting the grid control signal, the requirement for the driving capacity of the output module is reduced, the layout size of the grid driving circuit is reduced, the potential of the first output end can be kept stable in the level change process of the level transmission signal, and the reliability of the grid driving circuit is improved. And the influence of residual charges, electric leakage and other factors on the gate control signal output by the first output end is reduced.

The invention belongs to the technical field of cross-domain unmanned systems, and particularly discloses a buoyancy-driven rotary binocular camera device for an amphibious robot, which comprises a base assembly, a connecting assembly and a camera assembly, the base assembly comprises a base shaft, a fixing piece and a rotation control piece. The connecting assembly comprises a connecting rod, a balance weight piece and a buoyancy piece, the camera assembly comprises a first camera close to the balance weight piece and a second camera close to the buoyancy piece, the first camera is provided with a first water immersion switch, and the second camera assembly is provided with a second water immersion switch.
