| 摘要 |
<p>This invention relates to an unequal focus length and high magnification virtual image displayer consisting of an image displayer, an optically transparent material and a reflector; the optically transparent material is obliquely set between the image displayer and reflector, the optically transparent material is coated with a backward anti-reflecting film at the side to the image displayer, and with a polarizing film or polarizing film and forward anti-reflecting film at the other side, and the sum of the angle between the reflector and optically transparent material and the coating angle of the backward anti-reflecting film is 90°. This invention is an innovative optic improvement based on the design of dual-refraction virtual image optic displayer. The virtual image in the space is larger and clearer by higher magnification without any distortion, and the application can satisfy the market demand for HMD (head mounted displayer) products.</p> |
