Abstract: A display module, a manufacturing method of the display module, and a spliced module are provided. The display module includes a middle frame, a plurality of planarization layers, and a display panel. A plurality of accommodating grooves are formed on a surface of the middle frame, and the planarization layers are respectively disposed in the accommodating grooves. Supporting surfaces of the planarization layers are coplanar. The display panel is disposed on the supporting surfaces of the planarization layers by a plurality of bonding adhesives. Since the planarization layers are formed by a leveling processing, the planarization layer has good surface flatness.

Abstract: A door lock device is provided. The door lock device includes a panel and a mounting base. The panel is arranged opposite to the mounting base and is connected with the mounting base. The mounting base includes a recess located in a middle of one side of the mounting base and on a first surface of the mounting base close to the panel, and the recess and the panel form a handle structure.

Abstract: Examples frame synchronization methods and apparatus for image signal processing are described. One example method includes receiving a frame synchronization instruction sent by a first image collection apparatus of a terminal. The frame synchronization instruction is separately sent to a second image collection apparatus and a third image collection apparatus of the terminal, so that the second image collection apparatus, the third image collection apparatus, and the first image collection apparatus synchronously output frame image data. The example method further includes receiving the frame image data synchronously sent by the first image collection apparatus, the second image collection apparatus, and the third image collection apparatus.
