The embodiment of the invention provides a water-cooling heat dissipation display module, and the display module comprises a display panel and a lamp panel, wherein a plurality of LED lamp beads are arranged on the top face of the side, close to the display panel, of the lamp panel, and a heat dissipation cavity is formed at the bottom of the side, away from the display panel, of the lamp panel. A cooling water strip is arranged in the heat dissipation cavity and arranged along the inner surface of the heat dissipation cavity. According to the display module provided by the invention, the cooling water strip is arranged in the heat dissipation cavity, so that the heat dissipation rate can be increased, the normal working temperature of the lamp panel is ensured, the phenomenon of overhigh temperature is avoided, and the light emitting efficiency, the working stability and the service life of the LED lamp beads are ensured to be normal. In addition, due to the fact that the heat generated by the lamp panel is absorbed in time, the working stability of the display panel can be guaranteed.
