Embodiment 1

[0055] figure 1 A schematic structural diagram of a display unit provided with a quantum rod layer provided in Embodiment 1 of the present invention. figure 2 A schematic structural diagram of a display unit provided with a wire grid polarizing layer provided in Embodiment 1 of the present invention.

[0056] The inventors of the present invention found in the actual research process that in the current near-eye display system, in order to ensure the clarity of the image in the human eye, it is usually necessary to adjust the optical path of the light that the image enters into the human eye. However, since the image of the near-eye display system includes the near-eye display image of the virtual screen and the external transmission image including the real screen, the current optical path adjustment process of the light will simultaneously generate the imaging optical path of the near-eye display image and the imaging optical path of the external transmission image.

Embodiment 2

[0094] image 3 A schematic structural diagram of a display unit provided with a quantum rod layer provided in Embodiment 2 of the present invention. refer to image 3 As shown, on the basis of the first embodiment above, the second embodiment of the present invention also provides a display unit 100 with another structure. Compared with the first embodiment, the difference between the second embodiment and the first embodiment is that the refractive index matching layer 30 and the placement positions of the anisotropic material layer 40 are different.

[0095] Specifically, the refractive index matching layer 30 is stacked between the anisotropic material layer 40 and the optical characteristic changing layer 20 .

[0096] It should be noted that, referring to image 3 As shown, the refractive index matching layer 30 is attached to the surface of the optical characteristic changing layer 20 away from the linear polarization layer 10 , and the distance from the light emitti...

Abstract

The present invention provides a display unit, a near-eye display optical module, and a near-eye display system. The display unit includes a linear polarization layer, an optical characteristic changing layer, and a functional layer that are sequentially stacked; the functional layer is provided with a curved surface, and the curved surface constitutes a refraction surface. A light-emitting element with a light-emitting direction facing the light-characteristic changing layer is arranged on the refracting surface, and the light of the external ambient light passes through the linear polarization layer, the light-characteristic changing layer and the functional layer in sequence, and the light emitted by the light-emitting element passes through the light-characteristic changing layer and the functional layer, and Refraction occurs at the refraction surface, and the light rays passing through the light-emitting element of the light characteristic changing layer and the functional layer are parallel to the light rays of the external ambient light. The invention can ensure that both the near-eye display image in the human eye and the external transmission image have higher display brightness and definition, and improves the imaging quality of the near-eye display system.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a display unit, a near-eye display optical module and a near-eye display system. Background technique [0002] Augmented Reality (AR for short) is a technology that uses virtual objects and information to enhance the reality of real scenes, so that virtual objects and real environments can be superimposed in the same picture or space. Widely used in various fields such as scientific research, military, industry, games, video and education. [0003] The current near-eye display system generally includes a transparent or translucent display screen, a negative lens and a positive lens. The image of the near-eye display system includes a near-eye display image and an external transmission image, both of which are formed through different imaging optical paths in the near-eye display system. The near-eye display image is formed by the display screen projecting the image on...
