Summary:The utility model discloses an embedded ultrathin large-screen rear-projection interaction table comprising a casing, a screen, laser catchers, a light engine, a small reflective mirror, a large reflective mirror, an embedded interaction system, a heat dissipation apparatus and a power supply apparatus, wherein the screen is arranged on a front surface of the casing, the laser catchers are mounted around the screen; and the light engine, the small reflective mirror, the large reflective mirror, the embedded interaction system, the heat dissipation apparatus and the power supply apparatus are disposed in the casing. Light signals emitted by the light engine are successively reflected by the small reflective mirror and the large reflective mirror and are projected on the screen finally. The interaction table is characterized in that the small reflective mirror is a small arc-surface reflective mirror and is arranged below the screen, and the large reflective mirror is mounted behind the screen and is parallel w
