Abstract

The invention discloses a head-up display, comprising a housing, a projector, a coincidence lens, a plurality of dust covers and a moving module. The housing is provided with an opening. The dust covers are coupled with the housing. The projector is arranged in the housing to provide image light beams. When the dust covers seal the opening, the coincidence lens is arranged in the housing. When the dust covers do not seal the opening, the coincidence lens can be moved out of the housing through the opening and moved to a transmission path of the light beams. The moving module is arranged in the housing and is coupled with the dust covers, so that the dust covers can move relative to the housing.
