Abstract
A virtual imaging display device includes a base board; a panel configured to be rotatably provided at one of sides of the base board; a lens mounting board configured to be rotatably provided at a side of the panel facing the base board; a projecting lens configured to be mounted on the lens mounting board; and a plurality of half-transmitting mirrors configured to be rotatably provided at remaining sides of the base board, respectively. The virtual imaging display device has a deployed state in which the lens mounting board and the half-transmitting mirrors are configured to abut on each other to define together a frustum structure, and a collapsed state in which the half-transmitting mirrors each are configured to rest on the base board, the lens mounting board is configured to rest on the panel, and the panel is configured to rest on the base board.
