  • Patent number: 9507174
    Abstract: A spatial focal field type glasses display product can present virtual images at different distances simultaneously. The product is a frame type glasses or corneal contact lens and comprises a projection component and a display control device. The projection component comprises a plurality of projection units, each projection unit projects a plurality of elementary beams. The elementary beams projected by the same projection unit diverge and do not intercept with each other. The elementary beams projected by different projection units intersect near the retina after passing through the crystalline lens. The intersection point is a cluster focus. All cluster focuses form a spatial focal field which envelop the retina. When the diopter of the crystalline lens changes, the spatial focal field displaces and deforms accordingly, so different cluster focuses fall on the retina to be seen clearly, while the other cluster focuses tend to disperse and cannot be seen clearly.
