Description

TECHNICAL FIELD

[0001] The present application relates to the field of biomimetic display and near-eye display, in particular to a biomimetic near-eye display system based on a direct-view micro-nano display screen array. BACKGROUND

[0002] Near-eye display is the most important human-computer interaction and virtual-real fusion device in the meta-universe industry, which is a kind of glass or goggle type wearable display device composed of micro display panel and imaging optical device. In general, whether it is augmented reality AR, virtual reality VR, mixed reality MR or extended reality XR, it is collectively referred to as near-eye display in the technical field. In the traditional near-eye display, the optical architecture of AR mainly includes half-mirror, Birdbath structure, free-form surface structure, retina projection and optical waveguide scheme, which can be divided into transmission, reflection and diffraction according to the propagation mode of the image source light. The optical scheme of VR mainly includes lens, folded light path, free-form surface structure, etc. The miniaturization of the existing optical scheme has certain difficulty, and the image source light will have great energy and brightness loss in the propagation process, which has a higher requirement on the brightness of the image source, increases the energy consumption of the overall structure, and then causes heating, which is not conducive to the comfort of wearing and affects the endurance of the augmented reality device. SUMMARY

[0003] The applicant found that with the development and maturity of micro-nano display technology, Micro-OLED / Micro-LED / Micro-QLED display screens are getting smaller and smaller, and can realize transparent display. Therefore, directly configuring a micro display screen array in an eye lens, and directly entering the content of different micro display screens into the eyes of a person through fusion, can greatly reduce the optical loss of the optical path and reduce power consumption. Moreover, different display screens are similar to compound eye structures, which can realize the adjustment and fusion of different colors, resolutions, depths and refresh rates. Among them, the colorization of multi-primary color micro display screens is more consistent with the visual health of the human eye than red, green and blue three primary colors; different micro display screens can focus on different depth planes to realize 3D display, and the display content resolution of different depth planes and display areas is different, which is more consistent with the viewing characteristics of the human eye (the human eye requires higher resolution for the middle viewing area and the near depth plane). Different refresh rates can simulate the "half-brain sleep mode" of the owl, so that each area of the display picture has different refresh rates, and the power consumption of each area is different, achieving the purpose of energy saving. For example, the near-eye display product can automatically use a higher refresh rate in the game area, while the part where the present application is located can use a lower refresh rate to reduce display power consumption.

[0031] The present application discloses a bionic near-eye display system based on a direct-view micro-nano display screen array, and those skilled in the art can improve technical details to realize it by referring to the content of the present application. It should be particularly pointed out that all similar replacements and changes are obvious to those skilled in the art, and they are regarded as being included in the present application. The method and application of the present application have been described by the preferred embodiments, and relevant personnel can obviously modify or appropriately change and combine the method and application described in the present application without departing from the content, spirit and scope of the present application, to realize and apply the present application technology.

[0032] The applicant has found that, with the development and maturity of micro-nano display technology, Micro-OLED / Micro-LED / Micro-QLED display screens are getting smaller and smaller and can realize transparent display. Therefore, directly configuring a micro display screen array in an eye lens, and directly entering the content of different micro display screens into the eyes of a person through fusion can greatly reduce optical loss of an optical path and reduce power consumption. In addition, different display screens are similar to an ommatidium structure, and can realize adjustment and fusion of different colors, resolutions, depths and refresh rates. Among them, the colorization of a multi-primary color micro display screen is more in line with the visual health of the human eye than red, green and blue three primary colors; different micro display screens can focus on different depth planes to realize 3D display, and the display content resolutions of different depth planes and display areas are different, which is more in line with the viewing characteristics of the human eye (the human eye requires higher resolution for the middle viewing area and the depth plane close to the human eye). Different refresh rates can simulate the "half-brain sleep mode" of an owl, so that each area of a display image has a different refresh rate and each area has a different power consumption, so as to achieve the purpose of energy saving. For example, a near-eye display product can automatically use a higher refresh rate in a game area, while some parts of the present application can use a lower refresh rate to reduce display power consumption.

[0033] In summary, with the development of electronic information technology, people have higher requirements for miniaturization and low power consumption of near-eye display products. In view of the problems of miniaturization difficulty, low optical utilization rate and high power consumption of existing near-eye display products, the present application combines bionic engineering and proposes a bionic near-eye display system combining ommatidium, owl "half-brain sleep mode" and other bionic concepts. Information is directly displayed through multiple display screens, the depth, resolution and refresh rate can be adjusted in different areas, and the color fusion is more healthy.

[0034] Therefore, the bionic near-eye display system based on the direct-view micro-nano display screen array according to an embodiment of the present application comprises Figure 1 as shown, the bionic near-eye display system comprises:

[0036] A sensor module 103 for collecting user data and environmental data;

[0037] An optical module 104 for adjusting the optical path of light of the micro-nano display screen;

[0038] A power supply and light switch module 107 for power supply;

[0039] A drive module 105 for control and driving;

[0040] The light regulation module 106 is configured to regulate the light of the micro-nano display screen.

[0041] Figure 1 The user's eyeball is 108, i.e., the user's eyeball 108.

[0042] The bionic near-eye display system is configured to: in response to a video display signal, each micro-nano display screen independently displays corresponding display content in a compound eye working mode according to the video display signal, and focuses light on different depth planes through the light regulation module 106 to realize stereoscopic display; the control sensor module 103 acquires the human eye focal point of the user through eyeball tracking, and controls the pixel resolution of each micro-nano display screen in the transparent micro-nano display screen array 102 to decrease from the center of the human eye focal point to the periphery; corresponding dynamic views and static views in the video display signal are acquired, and the refresh rate of each micro-nano display screen corresponding to the dynamic views is higher than the refresh rate of each micro-nano display screen corresponding to the static views.

[0043] In this specific embodiment, the views of the bionic near-eye display system are seamlessly fused from a plurality of display regions provided by the transparent micro-nano display screen array 102, and are adjusted through eyeball tracking and artificial intelligence image algorithms; the pixel resolution of the display region at the human eye focal point is higher than that of the peripheral display region, the area where the user is looking produces an image of a first resolution, and the other parts of the field of view remain in a second resolution area, the first resolution being greater than the second resolution; the resolution of the display region at a depth plane close to the human eye is higher than that of the display region far from the human eye; the refresh rate of the display region for displaying dynamic views is higher than the refresh rate of the display region for displaying static views, and the refresh rate frequency range of the display region is 1 Hz-240 Hz.

[0044] It should be noted that, in the present embodiment, the bionic compound eye working mode is directly displayed by a plurality of micro-nano display screens, compared with the prior art, without a complex optical system, the system structure is simplified, the energy consumption is reduced, and the situation of the corresponding equipment being hot is reduced. In the present embodiment, different resolutions and refresh rates are allocated to different display regions, so that some non-key viewing objects of the user (under the premise of not affecting the viewing quality) obtain lower resolutions and refresh rates, and the energy consumption is reduced.

[0045] It is worth mentioning that the refresh rates of the same micro-nano display screen are the same, and in the present embodiment, the pixel resolution of each micro-nano display screen decreases from the center of the human eye focal point to the periphery, which means that the resolution of the micro-nano display screen farther from the human eye focal point is lower.

[0046] In this specific embodiment, both the pixel resolution and the refresh rate can decrease from the center of the human eye focal point to the periphery.

[0047] In this specific embodiment, the micro-nano display screen includes a color screen and / or an N-primary monochrome screen, N being a natural number greater than or equal to 3.

[0049] It should be noted that the multi-primary screen uses other color elements in addition to red, green, and blue, such as yellow, so that it can more accurately restore and represent a variety of colors in nature. Due to the increase in color elements, the multi-primary screen can cover a wider color gamut, making the display effect more realistic and lively. Multi-primary technology can be combined with high-resolution display to ensure the accuracy of color and the sense of hierarchy when presenting complex images.

[0050] In this specific embodiment, the light control module 106 includes an optical lens combination, a liquid crystal optical element, a nano grating array, and a superstructure surface.

[0051] It should be noted that these optical devices can better help the light to be regulated.

[0052] In this specific embodiment, the pixel resolution of the micro-nano display screen ranges from 100 ppi to 100,000 ppi; the micro-nano display screen includes a micro light-emitting diode (Micro-LED), a micro organic light-emitting diode (Micro-OLED), a micro quantum dot light-emitting diode (Micro-QLED), a nano light-emitting diode (Nano-LED), a liquid crystal on silicon (LCoS), a digital light processing display (DLP), and a laser beam scanning display (LBS).

[0053] In this specific embodiment, the sensor module 103 includes an interaction sensor, an optical camera, a microphone, a spatial environment perception sensor, a depth perception sensor, an eye movement tracking sensor, and an eye tracking sensor.

[0054] It should be noted that the sensor module 103 is used to collect real-time data of the user and real-time data of the environment, so that the system can make corresponding adjustments based on these data to ensure the user's viewing experience.

[0055] In this specific embodiment, the bionic near-eye display system automatically adjusts the interpupillary distance of the monocular through a micro stepping motor.

[0056] It needs to be explained that the importance of interpupillary distance (IPD), which refers to the distance between the centers of the pupils of both eyes in millimeters. For near-eye display devices such as AR / VR glasses, accurate matching of interpupillary distance is crucial to ensure a comfortable visual experience and avoid visual fatigue. If the IPD is not set properly, the user may see the image edges cut off, blurred vision, and even cause dizziness and other problems. Micro stepping motor is a motor that can accurately control the rotation angle and position, which is very suitable for automatic adjustment of IPD. Through the micro stepping motor integrated in the AR / VR glasses, the system can automatically or manually adjust the interpupillary distance according to the user's interpupillary distance.

[0057] In this embodiment, the optical module 104 includes a lens group, a polarized reflection device, a phase modulator, and a beam splitter.

[0058] In this embodiment, the transparent micro-nano display screen array 102 disposed on the vision correction optical lens 101 includes embedding the transparent micro-nano display screen array 102 on the frame of the biomimetic near-eye display system, embedding the transparent micro-nano display screen array 102 in the vision correction optical lens 101, pasting the transparent micro-nano display screen array 102 on the vision correction optical lens 101, growing or transferring the micro-nano display screen directly on the transparent micro-nano display screen array 102.

[0059] In the first embodiment, the arrangement of each micro-nano display screen is matrix arrangement.

[0060] In the first embodiment, the working schematic diagram is as shown in Figure 2 The transparent micro-nano display screen array 102 is disposed in front of the human eye, and the number is 9. The pixel resolution of each micro-nano display screen is different, and the pixel array is m x n (m, n are natural numbers greater than or equal to 16). The micro-nano display screen does not need to go through complex optical transmission, but directly reconstructs the image with different information in the human eye through a working mode similar to the compound eye, providing different display content. The pixel resolution of the micro-nano display screen in front of the human eye decreases along the two sides. The micro-nano display screen focuses light on different depth planes through the light control module 106 to realize stereoscopic display, and the pixel resolution of the micro-nano display screen decreases as the depth plane moves away from the human eye. The micro-nano display screen includes a color screen and an N-primary color monochrome screen (N is a natural number greater than or equal to 3). The refresh rate of the micro-nano display screen can be automatically adjusted according to the display content, realizing low-power display. In the grid density in Figure 2 The grid density can represent the resolution, and the greater the grid density, the higher the resolution.

[0061] In the first embodiment, the transparent micro-nano display screen array 102 is directly grown on the lens. The arrangement of the micro-nano display screen is matrix arrangement as shown in Figure 3 The corresponding resolution and refresh rate information is as shown inFigure 4 The grid density in the figure can represent the resolution level, and the greater the grid density, the higher the resolution. Figure 3 The grid density in the figure can represent the resolution level, and the greater the grid density, the higher the resolution.

[0062] In a second specific embodiment, the arrangement of each micro-nano display screen is annular arrangement.

[0063] In a first specific embodiment, the working schematic diagram is as shown in Figure 5 The transparent micro-nano display screen array 102 is arranged in front of the human eye, and the number is 9. The pixel resolution of each micro-nano display screen is different, and the pixel array is m x n (m and n are natural numbers greater than or equal to 16). The micro-nano display screen does not need to pass through a complex optical transmission and directly reconstructs an image with different information in the human eye through a compound eye working mode, thereby providing different display contents. The pixel resolution of the micro-nano display screen in front of the human eye decreases along the two sides. The micro-nano display screen focuses light on different depth surfaces through the light control module 106, thereby realizing stereoscopic display. As the depth surface is away from the human eye, the pixel resolution of the micro-nano display screen decreases. The micro-nano display screen includes a color screen and an N-primary color monochrome screen (N is a natural number greater than or equal to 3). The refresh rate of the micro-nano display screen can be automatically adjusted according to the display content, thereby realizing low-power display.

[0064] In a first specific embodiment, the transparent micro-nano display screen array 102 is arranged by directly growing on the lens. The arrangement of the micro-nano display screen is annular arrangement as shown in Figure 6 The resolution and refresh rate information corresponding to the arrangement are as shown in Figure 7 The grid density in the figure can represent the resolution level, and the greater the grid density, the higher the resolution. Figure 6 The grid density in the figure can represent the resolution level, and the greater the grid density, the higher the resolution.

[0065] In a third specific embodiment, the arrangement of each micro-nano display screen is specific arrangement according to an application scenario.

[0066] In the embodiment of the application, the transparent micro-nano display screen array 102 includes M micro-nano display screens, and the pixel array of the micro-nano display screen is m x n. In response to a video display signal, each micro-nano display screen independently displays corresponding display content in a compound eye working mode according to the video display signal, and focuses light on different depth surfaces through the light control module 106, thereby realizing stereoscopic display. In the embodiment of the application, each micro-nano display screen of the transparent micro-nano display screen array 102 directly displays the content to be displayed. Compared with the complex optical system in the prior art, the content of different micro-nano display screens directly enters the human eye through fusion, which can greatly reduce the optical loss of the optical path and reduce the power consumption.

[0067] The embodiment of the present application controls the sensor module 103 to collect the human eye focus of the user through eye tracking, and controls the pixel resolution of each micro-nano display screen in the transparent micro-nano display screen array 102 to decrease from the human eye focus to the periphery. The embodiment of the present application makes the area where the user is looking clear and the corner of the visual line low in clarity through the above control mode, so that the user's viewing experience is ensured while the resource loss caused by maintaining high resolution is reduced and the energy consumption is lowered.

[0068] The embodiment of the present application acquires the corresponding dynamic view and static view in the video display signal, and controls the refresh rate of each micro-nano display screen corresponding to the dynamic view to be higher than the refresh rate of each micro-nano display screen corresponding to the static view. Since the dynamic view changes greatly and the static view changes little, the refresh rate control mode of the embodiment of the present application ensures the high refresh rate of the dynamic view to improve the user experience, while the low refresh rate of the static view does not affect the user and can reduce the energy consumption. Different refresh rates can simulate the "half-brain sleep mode" of the owl, so that each area of the display picture has different refresh rates and each area has different power consumption, achieving the purpose of energy saving.

[0069] The micro-nano display screen of the embodiment of the present application can adopt an N-primary color monochrome screen, where N is a natural number greater than or equal to 3. The use of the multi-primary color screen in the embodiment of the present application can improve the display color restoration degree, not only improving the display quality, but also being more in line with the visual health of the human eye.

[0070] In summary, compared with the existing near-eye display, the embodiment of the present application realizes information direct display through multiple display screens, and the depth, resolution and refresh rate can be adjusted in zones, and the color fusion is more healthy for vision. The embodiment of the present application improves the display quality of the near-eye display system while reducing the energy consumption.
