It will be appreciated that the display stand 300 is connected to the panel 100 by RTV glue 540: when the thickness of the RTV glue 540 between the display screen bracket 300 and the panel 100 is too thick, the buffer space between the display screen bracket 300 and the panel 100 is increased, so that the positioning column 5101 is sunken, and the force generated when the positioning hole and the positioning column 5101 are connected by the screw is compressed by the RTV glue 540 because the cured RTV glue 540 is an elastomer, so that the thickness of the RTV glue 540 is thinned, and the heights of the positioning column 5101 and the positioning hole gradually tend to be consistent. When the thickness of the RTV glue 540 between the display bracket 300 and the panel 100 is too thin, the positioning posts 5101 protrude, and a force generated when the screw is connected to the positioning holes and the positioning posts 5101 acts on the protruding positioning posts 5101 without acting on the RTV glue 540 between the display bracket 300 and the panel 100, so that the IML panel is not pressed. By the arrangement, the thickness requirement of RTV glue 540 between the display screen bracket 300 and the panel 100 can be reduced, the stress of the touch cover plate 210 and the display module 220 is further reduced, and the vibration and impact resistance of the whole vehicle-mounted display device is improved.
