Apparatus and method of displaying augmented reality |
| abstract |
An apparatus and method for displaying augmented reality are disclosed. An apparatus for displaying disclosed augmented reality includes an optical engine; A first polarizing plate; A polarization converter configured to maintain or convert the polarization direction of the light of the real scene passing through the first polarizing plate by electrical control; A light guide plate through which light of a virtual image is output and light of a real scene is transmitted; A variable focus lens for adjusting a focal length of the light of the virtual image output from the light guide plate; A second polarizing plate disposed between the light guide plate and the variable focus lens or between the polarizing converter and the light guide plate; And controlling the optical engine to output the light of the virtual image during the virtual period, controlling the polarization converter such that at least a portion of the light of the real scene is blocked by the second polarizing plate, and a focus variable lens to have a first focal length for the light of the virtual image. Control, and control the optical engine so as not to output the light of the virtual image during the actual image period, control the polarization converter so that the light of the real scene passes through the second polarizing plate, and change the focus to have a second focal length different from the first focal length It includes; a processor for controlling the lens. |
