    摘要: A dual-sided imaging thin film display structure is provided, comprising a light source, a reflective polarizing element, a basing layer and a linear polarizing element. The reflective polarizing element is disposed on a front surface of the light source, the basing layer is disposed on a back surface of the light source, and the linear polarizing element is further disposed behind the basing layer. A transmission axis of the reflective polarizing element and that of the linear polarizing element are orthogonal, such that a light beam emitted from the light source passes through the reflective polarizing element to form a front image, be reflected by the reflective polarizing element, and passes through the linear polarizing element to form a back image. By employing the present invention, it achieves to provide dual-sided images and interferences between the images are suppressed to obtain superior imaging quality and resolution.

    摘要: A head-up display includes a picture generation unit configured to project image light, a hexagonal optical reflection element arranged on a light path of the image light and including a hollow hexagonal cylinder, a concave mirror and an image display plate. The hollow hexagonal cylinder has a first sidewall, a second sidewall, a third sidewall, a fourth sidewall, a fifth sidewall and a sixth sidewall which are sequentially connected to form a closed hexagonal column. The second sidewall is transparent, and the first sidewall and the fifth sidewall opposite to the second sidewall are configured to reflect the image light. The concave mirror is disposed on the light path of the image light and configured to receive the image light reflected from the hollow hexagonal cylinder. The image display plate is configured to receive image light reflected from the concave mirror.
