Problems solved by technology

Then, there is a conflict between the convergence rotation of the human eye and the refraction adjustment (that is, the convergence conflict), and when the viewer continues to watch the dynamic 3D image, it is prone to adverse experiences such as eye fatigue and dizziness, which greatly reduces the user experience.

Embodiment 1

[0053] An embodiment of the present invention provides an optical display system, referring to figure 1 shown, including:

[0054] Display screen 1; the type of display screen is not limited here, for example, the display screen can be LCD (LiquidCrystal Display, liquid crystal display) display screen, OLED (Organic Light-Emitting Diode, organic light-emitting diode) display screen, Micro OLED Any one of micro-displays and Mini LED micro-displays; it can also be a DLP (Digital Light Processing, digital light processing) display; it can also be an LCOS (Liquid Crystal on Silicon, liquid crystal on silicon) display, etc. In addition, the display screen may be a flexible screen or a rigid screen (that is, a non-flexible screen). In practical applications, it can be selected according to user requirements.

[0055] The first light splitting unit 2 is arranged on the display side of the display screen 1; the light emitted by the display screen is converted into the first type of ...

Embodiment 2

[0102] An embodiment of the present invention provides a display device, including: the optical display system provided in Embodiment 1.

[0103] The display device can greatly improve human eye fatigue caused by convergence conflicts, and has the characteristics of high user experience, high light efficiency, and small volume. The display device may be a VR (Virtual Reality, virtual reality) display device, and may also be an AR (Augmented Reality, augmented reality) display device.

Embodiment 3

[0105] An embodiment of the present invention provides a method for controlling an optical display system as provided in Embodiment 1, including:

[0106] S01. In a first period of time, input a first focal plane image signal to a display screen.

[0107] The focal plane, also known as the focal plane, refers to the plane that passes through the focal point and is perpendicular to the main optical axis of the system.

[0108] S02. Control the display screen to display the first focal plane image.

[0109] S03. Control the first light splitting unit so that the light emitted by the display screen is converted into the first type of polarized light after passing through the first light splitting unit; after the first type of polarized light passes through the imaging unit, the second light splitting unit, and the first optical path unit in sequence, Inject the observation position.

[0110] S04. In a second time period, input a second focal plane image signal to the display sc...

Abstract

The invention provides an optical display system, a control method and a display device, and relates to the technical field of display. Convergence conflicts can be greatly reduced. The optical display system comprises a display screen, a first light splitting unit, an imaging unit, a second light splitting unit, a first light path unit, and a second light path unit, wherein light emitted by the display screen is converted into first type polarized light or second type polarized light after passing through the first light splitting unit; the light emitted by the first light splitting unit forms an amplified image corresponding to a first focal length after passing through the imaging unit; after the first type of polarized light transmitted by the second light splitting unit passes throughthe first light path unit, an amplified image corresponding to a second focal length is formed and converted into a second type of polarized light; and the second type of polarized light reflected bythe second light splitting unit is converted into the first type of polarized light after passing through the second light path unit. The system, the method and the device are suitable for manufacturing of the optical display system.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical display system, a control method, and a display device. Background technique [0002] When human eyes observe the real world, they rely on binocular parallax to produce stereoscopic vision. Based on this principle, researchers have developed VR (Virtual Reality, virtual reality) products and AR (Augmented Reality, augmented reality) products to achieve 3D display. [0003] When users watch VR products and AR products, the left and right eyes can see images of the same scene under different viewing angles, resulting in parallax; then the brain integrates the images to achieve stereoscopic display. [0004] During the viewing process, the two eyes adjust the diopter through the lens respectively, so that the image of the object is focused on the virtual image plane of the retina. When the brain integrates images, due to the depth difference between the three-dimension...
