AI Technical Summary
Technical Problem
Existing display technologies for stereoscopic images struggle to achieve high-definition displays.
Method used
A display device comprising a phosphor with a concave surface, a light source for excitation light, a scan mirror to reflect the excitation light, and a mirror driving mechanism to change the incidence position of the excitation light, along with variable focus lenses to correct aberrations and improve light concentration.
Benefits of technology
This configuration enables the display of higher-definition stereoscopic images by reducing aberrations and maintaining a small spot diameter of the excitation light across various light collection positions.

Abstract
To display a three-dimensional higher-definition image.SOLUTION: A display device 10B includes: a display body 12B having a concave surface 62; a light source 30 which outputs excitation light 20 that excites phosphors; a scan mirror 46 which reflects the excitation light 20 toward the concave surface 62; and a mirror driving mechanism 48 which drives the scan mirror 46 to change a light-incident position 64 of the excitation light 20 on the concave surface 62.SELECTED DRAWING: Figure 5
