A virtual display apparatus includes: a flexible display component layer having a light exit surface and a non-light exit surface opposite to the light exit surface; a lens layer disposed at the light exit surface of the flexible display component layer, and configured to converge light; a curvature adjustment layer disposed on the non-light exit surface of the flexible display component layer. The lens layer has a first surface facing the flexible display component layer, and the first surface of the lens layer and the light exit surface of the flexible display component layer have a gap therebetween. The curvature adjustment layer is configured to deform in response to at least one deformation signal, so as to adjust distances between the first surface of the lens layer and different positions of the light exit surface of the flexible display component layer along a thickness direction of the lens layer.
