Abstract

The embodiment of the present invention discloses a transflective film and an aerial display device. The aerial display device comprises: a first polarizing device and a second polarizing device disposed on a box; and a transflective structure and a transflective film disposed between the first polarizing device and the second polarizing device. The aerial display device is provided with a first quarter-wavelength plate at a side close to the first polarizing device. A second quarter-wavelength plate is disposed between the transflective structure and the transflective film. According to the aerial display device, the polarized light passing through the first polarizing device is processed by an optical path inside the aerial display device such that the polarized light passing through thesecond polarizing device forms an aerial image. The embodiment of the present invention solves the problems in the existing aerial imaging technology that a display device is large in size, complicated in structure, simple in displayed images, and poor in display effect, and has difficulty in displaying three-dimensional images.

Description

technical field [0001] This application relates to but not limited to the technical field of in-air display, especially a semi-permeable and semi-reflective membrane and an in-air display device. Background technique [0002] Aerial imaging technology refers to the direct display of two-dimensional or three-dimensional images in the air without a medium, so that people or objects can directly "pass through" the screen, so as to achieve a good interactive and immersive display effect. [0003] At present, the relatively mature aerial display products on the market are mostly applied by projection technology, such as: aerosol projection display, holographic projection display and laser projection display. Among them, the aerosol projection display is to project the ordinary projection screen on the aerosol, the display screen is flat, and the image quality is extremely unstable; the holographic projection display is to divide the light emitted by the bottom light source into t...
