Embodiment 1

[0037] A kind of display system of this embodiment, refer to figure 1 , including an image source device 1 and a developing device 2, the light emitted by the image source device 1 reaches the developing device 2 and is reflected to the human eye through the developing device 2; the image source device 1 emits P-polarized light, and the light emitted by the image source device 1 The P-polarized light is incident on the imaging device 2 at a certain angle, and then reflected to human eyes through the imaging device 2 . refer to figure 2 , the imaging device 2 comprises a transparent substrate 200 and a polarized transflective film 201 disposed on the inner surface of the transparent substrate that reverses P polarized light and transmits S polarized light. The polarizing transflective film 201 is used to reflect the incident light of P polarized light to human eyes to form a virtual image, and the polarizing transflective film 201 that reverses P polarized light and transmits...

Embodiment 2

[0039] A display system of this embodiment is based on Embodiment 1, refer to figure 2 , the imaging device 2 includes an anti-reflection film 202, which is arranged on the outer surface of the transparent substrate 200, adopts a polarized transflective film that reverses P-polarized light and transmits S-polarized light, and the S-polarized light of external ambient light passes through The anti-P polarized light transmits the polarized transflective film of the S polarized light to the human eye, and the polarized transflective film for the anti-P polarized light and transmitted the S polarized light has a higher transmittance to the S polarized light of the external ambient light. Adding an anti-reflection film on the outer surface of the material can further increase the transmittance of the S-polarized light of the external ambient light, so that the driver can observe the displayed information more clearly and can see the external environment more clearly.

Embodiment 3

[0041] A display system in this embodiment is based on the second embodiment. The polarized transflective film that reverses P-polarized light and transmits S-polarized light is made of a polymer film, and the polarized transflective film that reverses P-polarized light and transmits S-polarized light is made of a similar polarized transflective film. The film layers with high and low refractive index changes between the adjacent film layers are stacked. The polarized transflective film that reverses P polarized light and transmits S polarized light made of polymer film has a reflectivity of 100% for P polarized light. The transmittance of S-polarized light in the external environment is over 50%, and the light efficiency is extremely high, which truly realizes the high transmittance and high reflection of the display system. See the external environment.

Abstract

The invention discloses a display system and belongs to the technical field of optical display. The display system comprises an image source device and an image display device; the image source deviceemits P polarized light; the P polarized light emitted by the image source device enters the image display device at a certain angle; light emitted by the image source device reaches the image display device and then is reflected to human eyes through the image display device; the image display device comprises a transparent base material and a polarization transflective film which is arranged onthe inner surface of the transparent base material and used for reflecting P polarized light and transmitting S polarized light; the polarization transflective film reflecting the P polarized light and transmitting the S polarized light reflects P polarized light incident light to human eyes to form a virtual image, and meanwhile, the S polarized light of external environment light penetrates through the polarization transflective film reflecting the P polarized light and transmitting the S polarized light so as to reach the human eyes. The device is high in lighting effect and low in power consumption; a driver can clearly observe display information, and meanwhile, the viewing of the external environment is not hindered.

Description

technical field [0001] The invention belongs to the technical field of optical display, and in particular relates to a display system and a display method. Background technique [0002] A transparent display system usually consists of an image source and an imaging window. In existing transparent display systems, there are multiple options for image sources and imaging windows. The imaging window is usually composed of a base material and a reflective surface. Most imaging windows use the reflective surface as an interlayer in the base material, making the manufacturing process more difficult. [0003] In the prior art, there is a technical solution of using a source emitting p-polarized light as an image source. For example, Chinese patent applications CN204143067U and CN104267498A, US patent applications US6952312B2, US7123418B2 and US7355796B2, and European patent application EP0836108A2 all mention imaging methods using p-polarized light. [0004] However, these imagi...
