The invention relates to a non-screen monitor, it includes: The pressurizing unit, the atomizing device, the steam fog generator, the projection equipment, its characteristic is; the pressurizing unit is the wind tunnel or the booster pump, the atomizing device is spray groove or the stereographic projection sprayer, one wind tunnel end connects with the steam fog generator, the another wind tunnel end with spray groove overage pipecoupling, the projects equipment setup on the seat apart from spray groove certain distant, the distant based on the clarity of the visual object on the fog act. This screen did not demonstrate when any also does not have, if must demonstrate, suddenly appears the calligraphy and painting in the mid air, not only can watch television, but also can provide a new advertisement picture for the billboard, according to material object, when the light emitting diode projects luminous spot composes the captions on the ultrasonic inhalator, its effect quite floweriness dazzle the eyes, also blind gas spray, when project television, the water used steam fog effect must be better than the ultrasonic inhalator, but can see the white fog appearance.
