A front-maintenance-type LED display module comprises an LED lamp plate (10) and a bottom shell (20) fixed to the LED lamp plate (10). An iron plate (11) fixed on the bottom shell (20) is arranged in a gap between the bottom shell (20) and the LED lamp plate (10). The LED lamp plate (10) and the bottom shell (20) are positioned by using positioning columns (22) and positioning holes (41), and are magnetically connected. By means of the arrangement of the iron plate (11), during maintenance, the LED lamp plate (10) can be conveniently taken down from the front by using a magnetic tool (90), and other tools are not needed, so that the LED display module is convenient and rapid to mount. Also disclosed is a front-maintenance-type LED display screen that comprises a case (40). A screw (48) is arranged in a mounting hole (49) of the case (40), a fixing pipe (47) is provided at a front end of the screw (48), an adjusting spring (46) is sleeved on the fixing pipe (47), and by rotating the screw (48), the front-and-back positions of the fixing pipe (47) and the case (40) can be adjusted, and the parallelism between the bottom shell (20) and the case (40) can be adjusted. |
