Abstract: An all-in-one computer includes a monitor and a host. The monitor includes a display screen, which has an accommodating cavity with an opening located on a peripheral side of the display screen, and the host is detachably mounted in the accommodating cavity from the opening along a first direction. The monitor is provided with a first connecting assembly, the host is provided with a second connecting assembly, and when the host is mounted in the accommodating cavity, the second connecting assembly is connected to the first connecting assembly to implement signal transmission between the host and the monitor. An arrangement direction of the second connecting assembly and the first connecting assembly is perpendicular to the first direction, and the arrangement direction of the second connecting assembly and the first connecting assembly is parallel to a plane on which the display screen is located.

Abstract: An outdoor display screen includes a housing, a display screen, a control module, a heat dissipation module, and a power supply component. A first cavity and a second cavity are disposed on the housing. The display screen, the control module, and the power supply component are mounted in the first cavity, and the heat dissipation module is mounted in the second cavity. A cable-through hole is disposed on the housing. An air exhaust vent connected to an air intake vent of an internal circulation path and an air intake vent connected to an air exhaust vent of the internal circulation path are disposed in the first cavity to form an internal circulation heat-dissipation air duct. An air intake vent and an air exhaust vent are disposed in the second cavity to form an external circulation heat-dissipation air duct.
