Embodiment 1

[0033] figure 1 Shown is a schematic structural diagram of an optical module provided by an embodiment of the present invention. This embodiment provides an optical module, such as figure 1 As shown, the optical module includes: a first image source 1, an imaging medium 2, a second image source 5, a first main scanner 6, a first sub-scanner 7, a focusing assembly 8, a second main scanner 9 and Second sub-scanner 10.

[0034] Wherein, the first image source 1 is used for displaying the first image, and the imaging medium 2 is used for imaging the first image, and the first image source 1 may be a projector or a self-luminous display panel, figure 1 The shown first image source 1 is a self-luminous display panel, the first image source 1 and the imaging medium 2 together constitute a display, and the imaging medium 2 is a transmission panel of the first image source 1, specifically, the imaging medium 2 may be flat glass . In addition, the first image source 1 can also be a ...

Embodiment 2

[0052] Optionally, the focusing assembly 8 includes: an off-axis focusing mirror group, the first main scanner 6 is located on the light-incoming side of the off-axis focusing mirror group, the second main scanner 9 is located on the light-emitting side of the off-axis focusing mirror group, and the off-axis The focusing lens group is used to focus the first scanning image track off-axis on the second main scanner 9 .

[0053] By means of off-axis focusing, it is possible to prevent the first main scanner 6 from blocking the reflected light path of the second main scanner 9, and to prevent the second main scanner 9 from blocking the reflected light path of the first main scanner 6, ensuring that the first All the image light emitted by the main scanner 6 can be irradiated on the second main scanner 9 , which also ensures that all the image light emitted by the second main scanner 9 can be irradiated on the imaging medium 2 .

[0054] Specifically, such as figure 1 As shown, t...

Embodiment 3

[0064] The present invention provides an optical system, which includes: the aforementioned optical module, two optical modules respectively serving as a left-eye viewing component and a right-eye viewing component, and the left-eye viewing component and the right-eye viewing component are symmetrically distributed. When in use, the user's left and right eyes view images from the two optical modules respectively.

Abstract

The invention relates to the technical field of optical display, and provides an optical module / system, a display device, a head-mounted display device and a display system, and during use, the central optical axis of a composite scanning image can be controlled to adjust the superposition position of the composite scanning image on a first image. Therefore, the high-resolution composite scanning image can be displayed at a specific position in an overlapping manner. Meanwhile, due to the fact that the requirement of human eyes for the image resolution of the central small-range view field is high, the central small-range view field of the human eyes can be aligned with the high-resolution composite scanning image for watching, and the watching experience of the high-resolution central view field of the human eyes can be improved. The requirement of human eyes for the resolution outside the central small-range view field is not high, so that the low resolution of the first image outside the central small-range view field does not affect the impression, the first image source can adopt the image source with the low resolution, and the overall device cost of the optical display device can be reduced.

Description

technical field [0001] The present invention relates to the technical field of optical display, in particular to an optical module / system, a display device, a head-mounted display device and a display system. Background technique [0002] In existing display technologies, a single image is generally displayed on a screen. If it is desired to superimpose and display images with different resolutions on the screen, a single screen cannot meet this requirement. How to superimpose and display images with different resolutions on one screen is a technical problem to be solved in this field. Contents of the invention [0003] In view of this, the present invention provides an optical module / system, a display device, a head-mounted display device, and a display system, which can realize overlapping display of images with different resolutions. [0004] In order to solve the above technical problems, the present invention provides an optical module, which includes: a first image...
