According to the transparent display screen, the sliding grooves 2 which are vertically spaced and transversely extend are formed in the transparent panel, the display modules 3 are slidably mounted in the sliding grooves 2, and the display modules 3 which are positioned in the same sliding groove 2 can be pulled out of the transparent panel by pulling the first tensioning rope 10, so that the damaged display modules 3 can be maintained or replaced conveniently, and the workload of maintenance workers is greatly reduced;

through setting up display module 3 in spout 2 the encapsulation thickness that has also reduced transparent display screen in this scheme to slider 28 through mutually supporting and slide 27 with display module 3 spacing in spout 2, through the connection cooperation of connecting rope 4 between the adjacent display module 3 in addition, make display module 3 more firm, difficult production is not hard up.
