Abstract

The present disclosure provides a display screen splicing device and a spliced display device. The display screen splicing device includes a substrate, at least two carrier plates, and a position adjustment assembly. The carrier plates are disposed on the substrate. The position adjustment assembly is connected between the substrate and the carrier plates. The position adjustment assembly includes a first adjustment member disposed on the substrate, and a second adjustment member movably connected to the first adjustment member. The second adjustment member is fixedly connected to the carrier plates. A movement track of the second adjustment member is parallel to a plane where the carrier plates are located.
