Description

Technical Field

[0001] The present application relates to the field of near-eye display, and in particular to a near-eye display device. Background Art

[0002] With the development of science and technology, augmented reality (AR) technology is being applied in various fields, such as gaming, education, healthcare, and retail. To provide a richer and more personalized interactive experience, AR display devices use a dialogue mode as the core channel for information exchange between users and devices. Its implementation mainly includes traditional interaction technologies such as voice commands, touch operation, gesture recognition, and eye recognition. Voice commands can cause command ambiguity in high-precision operation scenarios (such as medical surgery). Touch operation and gesture recognition rely on users operating the touch screen or spatial gestures. In complex environments (such as strong light interference), recognition failures are prone to occur, leading to interaction interruptions.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0022] It should be noted that when a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component. The term "and / or" as used herein includes all and any combinations of one or more of the relevant listed items. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] In order to further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following detailed description of this application is made in conjunction with the accompanying drawings and preferred implementation methods.

[0024] Please also refer to Figure 1 and Figure 2 The near-eye display device 100 of the present embodiment includes a frame 10 and two optical systems 11a and 11b disposed on the frame 10. The two optical systems 11a and 11b have substantially the same structure and function. One optical system 11a is disposed on the left side of the frame 10 and is used to form an image for the user's left eye; the other optical system 11b is disposed on the right side of the frame 10 and is used to form an image for the user's right eye.

[0025] The near-eye display device 100 in the embodiment of the present application is an AR display device. When a user wears the AR display device, the user's eyes can observe the projected image displayed by the two optical systems 11a and 11b. At the same time, ambient light L3 reflected by environmental objects W in the user's real environment can also enter the human eye E through the near-eye display device 100, allowing the human eye E to also observe the image of the real world, and further allowing the human eye E to observe the projected image superimposed on the image of the real world. In other embodiments, the near-eye display device 100 can also be an MR display device or an XR display device, which is not limited by this application.

[0026] The structure and function of the optical system 11a will be described below by taking the optical system 11a as an example.

[0027] Please also refer to Figure 1 and Figure 2 The optical system 11a of the embodiment of the present application includes a sensing module 2, an image light module 3 and a control module 4. The sensing module 2 includes an emitting component 21, a first waveguide 22, a sensing coupling grating 23, a sensing coupling out grating 24 and an information acquisition module 25. The emitting component 21 is used to emit the sensing light L1; the first waveguide 22 has a first surface 221 and a second surface 222 opposite to the first surface 221, which is used to transmit the sensing light L1; the sensing coupling grating 23 is arranged on the second surface 222 and is located on the optical path of the sensing light L1, and is used to receive and couple the sensing light L1 into the first waveguide 22; the sensing coupling out grating 24 is arranged on the second surface 222 with an interval between the sensing coupling grating 23 and the sensing coupling grating 23, and is used to receive and couple the sensing light L1 to the human eye E; the information acquisition module 25 is used to receive the sensing light L1 reflected from the human eye E and obtain the gaze information of the human eye E. The image light module 3 is disposed on one side of the first waveguide 22 and includes a second waveguide 31. The second waveguide 31 is used to receive and guide the image light L2 so that the image light L2 is incident on the human eye E. The image light L2 is used to display the projected image. The control module 4 is electrically connected to the image light module 3 and the sensing module 2. It is used to receive gaze information from the human eye E and adjust the displayed image of the image light L2 based on the gaze information of the human eye E. Specifically, the gaze information is the eye movement trajectory of the human eye E. The control module 4 can obtain the eye movement trajectory of the human eye E based on the gaze information, thereby determining the gaze position of the human eye E.

[0028] The near-eye display device 100 provided in the embodiment of the present application is provided with a sensing coupling grating 23, a sensing coupling grating 24 and an information acquisition module 25 in the sensing module 2. The sensing coupling grating 23 receives and couples the sensing light L1 into the first waveguide 22; the sensing coupling grating 24 receives and couples the sensing light L1 to the human eye E, the information acquisition module 25 receives the sensing light L1 reflected from the human eye E, and obtains the gaze information of the human eye E. The control module 4 then receives the gaze information of the human eye E and adjusts the display image of the image light L2 according to the gaze information of the human eye E. This can meet the needs of the user and the near-eye display device 100. Compared with the near-eye display device 100 that adopts the traditional interactive technology, the near-eye display device 100 provided by the embodiment of the present application obtains the gaze information of the human eye E, is not prone to the problem of command ambiguity, and is not prone to the situation where recognition failure occurs due to strong light infection; in addition, compared with the display device that obtains the gaze information of the human eye E through an external camera, the near-eye display device 100 of the embodiment of the present application is conducive to reducing the overall weight and volume of the near-eye display device 100, thereby helping to improve the portability of the near-eye display device 100, and further helping to improve the user experience.

[0029] In some embodiments, the emitting component 21 includes at least one infrared light emitting diode 211, and the wavelength range of the sensing light L1 emitted by the emitting component 21 is 750nm-1100nm. Specifically, the wavelength of the sensing light L1 can be 750nm, 780nm, 800nm, 820nm, 840nm, 860nm, 880nm, 910nm, 930nm, 950nm, 970nm, 1000nm or 1100nm; by setting the wavelength of the sensing light L1 to the above value, when the sensing light L1 is incident on the human eye E, since the human eye E has a low sensitivity to infrared light above 750nm, it is beneficial to avoid stimulating pupil contraction, thereby helping to improve the accuracy of the information acquisition module 25 in obtaining the gaze information of the human eye E.

[0030] Furthermore, by setting the wavelength of the sensing light L1 to the aforementioned value, compared to using sensing light L1 in the visible light band, the sensing light L1 in the aforementioned wavelength range can form bright Purkinje spots on the corneal surface of the human eye E, thereby further improving the accuracy of the information acquisition module 25 in acquiring the gaze information of the human eye E. In other embodiments, the emitting component 21 may further include at least one organic near-infrared light-emitting diode or infrared laser diode, which is not limited in this application.

[0031] The first waveguide 22 and the second waveguide 31 are both engaged with the frame 10 and have a generally rectangular plate-like structure. The first surface 221 and the second surface 222 of the first waveguide 22 have a generally rectangular outer profile. In some embodiments, the first waveguide 22 is made of amorphous material transmitting infrared radiation (AMTIR-1). In other embodiments, the material of the first waveguide 22 can also be any one of polyethylene glycol terephthalate (PET), polycarbonate (PC), and polymeric methyl methacrylate (PMMA), without limitation in this application. By making the first waveguide 22 of AMTIR-1, which has excellent thermal stability and high transmittance for visible light, the transmittance of ambient light L3 reflected by an object W is improved. The second waveguide 31 includes a third surface 311 and a fourth surface 312 opposite the third surface 311. The third surface 311 and the fourth surface 312 of the second waveguide 31 also have a generally rectangular outer profile. The material of the second waveguide 31 is chalcogenide glass AMTIR-1. The first waveguide 22 and the second waveguide 31 can be made of the same material, for example, both the first waveguide 22 and the second waveguide 31 can be made of chalcogenide glass AMTIR-1, or the first waveguide 22 can be made of chalcogenide glass AMTIR-1 and the second waveguide 31 can be made of PMMA, without limitation in this application.

[0032] In some embodiments, the sensing coupling-in grating 23 and the sensing coupling-out grating 24 may be any one of a surface relief grating, a volume holographic grating, and a polarization volume holographic grating. For example, the sensing coupling-in grating 23 and the sensing coupling-out grating 24 may both be surface relief gratings, or the sensing coupling-in grating 23 may be a surface relief grating, and the sensing coupling-out grating 24 may be a volume holographic grating. This is not limited in the present application.

[0033] In some embodiments, please refer to Figure 1 、 Figure 2 as well as Figure 3The information acquisition module 25 includes an information coupling-in grating 251, an information coupling-out grating 252, and a receiving element 253. The information coupling-in grating 251 is disposed on the second surface 222 and is used to receive the sensing light L1 reflected from the human eye E. The first waveguide 22 is used to guide the sensing light L1 emitted from the information coupling-in grating 251. The information coupling-out grating 252 and the information coupling-in grating 251 are spaced apart and disposed on the second surface 222 of the first waveguide 22. The information coupling-out grating 252 is used to receive and couple the sensing light L1 emitted from the first waveguide 22 to the receiving element 253. The receiving element 253 is a complementary metal oxide semiconductor (CMOS) receiver. The receiving element 253 is used to receive the sensing light L1 emitted from the information coupling-out grating 252 and obtain the gaze information of the human eye E. Specifically, the shape of the information coupling-in grating 251 projected onto the first waveguide 22 is roughly a quadrilateral. The information coupling-in grating 251 and the information coupling-out grating 252 can be any one of a surface relief grating, a volume holographic grating, and a polarization volume holographic grating, and this application does not impose any restrictions.

[0034] In some embodiments, the orthographic projection of the sensing outcoupling grating 24 on the first waveguide 22 is substantially annular in shape, the sensing outcoupling grating 24 surrounds the information coupling-in grating 251, and the orthographic projection of the sensing outcoupling grating 24 on the first waveguide 22 surrounds the orthographic projection of the information coupling-in grating 251 on the first waveguide 22. By setting the orthographic projection of the sensing outcoupling grating 24 on the first waveguide 22 to surround the orthographic projection of the information coupling-in grating 251 on the first waveguide 22, the sensing light L1 can be incident on the human eye E to a greater extent to illuminate the human eye E, thereby forming a bright Purkinje spot on the corneal surface of the human eye E. This allows the information acquisition module 25 to receive the sensing light L1 reflected from the human eye E to a greater extent and obtain gaze information of the human eye E.

[0035] In some embodiments, the sensing module 2 further includes a flexible circuit board base 26, on which the receiving element 253 and the transmitting assembly 21 are integrated. The control module 4 is electrically connected to the flexible circuit board base 26 to connect the receiving element 253 and the transmitting assembly 21. Providing the flexible circuit board base 26 to integrate the receiving element 253 and the transmitting assembly 21 further reduces the size of the sensing module 2, thereby further reducing the size and weight of the near-eye display device 100.

[0036] In some embodiments, the image light module 3 includes an image coupling-in grating 33 and an image coupling-out grating 35. The image coupling-in grating 33 is arranged on the fourth surface 312 for receiving and coupling the image light L2 into the second waveguide 31. The image coupling-out grating 35 is arranged on the fourth surface 312 with an interval between the image coupling-in grating 33 and the image coupling-out grating 35 for receiving and coupling the image light L2 out to the human eye E.

[0037] In this embodiment, please refer to Figure 2 and Figure 3 The third surface 311 is attached to the side of the sensing coupling-in grating 23 and the sensing coupling-out grating 24 away from the first waveguide 22, that is, the sensing coupling-in grating 23 and the sensing coupling-out grating 24 are located between the first waveguide 22 and the second waveguide 31; the image light L2 passes through the first waveguide 22 and is incident on the image coupling-in grating 33, is coupled to the second waveguide 31 by the image coupling-in grating 33, and then is incident on the image coupling-out grating 35. The image coupling-out grating 35 couples the image light L2 out to the first waveguide 22, and the image light L2 passes through the first waveguide 22 and is incident on the human eye; the ambient light L3 reflected by the environmental object W also enters the human eye E through the second waveguide 31 and the first waveguide 22 of the near-eye display device 100 in sequence. By setting the third surface 311 to be in contact with the side of the sensing coupling-in grating 23 and the sensing coupling-out grating 24 away from the first waveguide 22, the propagation path of the sensing light L1 can be shortened, which is beneficial to reducing the loss of the sensing light L1, thereby improving the receiving efficiency of the receiving element 253. Figure 3 and Figure 4 The first waveguide 22 is disposed on the side of the fourth surface 312 facing away from the third surface 311. The image coupling-in grating 33 and the image coupling-out grating 35 are located between the first waveguide 22 and the second waveguide 31. The sensing light L1 passes through the second waveguide 31 and is incident on the sensing coupling-in grating 23. It is then transmitted through the first waveguide 22 to the sensing coupling-out grating 24 before entering the human eye E. After illuminating the human eye E, part of the sensing light L1 passes through the second waveguide 31 and is reflected to the information coupling-in grating 251. It is then transmitted through the first waveguide 22 to the information coupling-out grating 252. Finally, the sensing light L1 coupled out of the information coupling-out grating 252 passes through the second waveguide 31 and is incident on the receiving element 253.

[0038] In some embodiments, the near-eye display device 100 further includes a light emitting assembly 5, which is used to emit image light L2, and the wavelength range of the image light L2 is 380nm-750nm. The light emitting assembly 5 is disposed on the frame 1010. The light emitting assembly 5 can be any one of a display using a DLP (Digital Light Processor) display mode, a micro light-emitting diode (Micro LED) display, a mini light-emitting diode (Mimi LED) display, and an organic light-emitting diode (OLED) display, and this application does not impose any restrictions.

[0039] The control module 4 can be any one of a central processing unit (CPU) and a single-chip microcontroller (e.g., an STM32 single-chip microcontroller, a 51 single-chip microcontroller, a TMS single-chip microcontroller, a PIC single-chip microcontroller, or an AVR single-chip microcontroller), and is not limited in this application. The control module 4 is electrically connected to the light emitting component 5 and the sensing module 2. After receiving the gaze information of the human eye E from the receiving element 253, the control module 4 determines the user's usage needs and adjusts the displayed image of the image light L2 based on the gaze information of the human eye E, thereby enabling information exchange between the user and the near-eye display device 100.

[0040] The near-eye display device 100 provided in the embodiment of the present application is provided with a sensing coupling grating 23, a sensing coupling grating 24 and an information acquisition module 25 in the sensing module 2. The sensing coupling grating 23 receives and couples the sensing light L1 into the first waveguide 22; the sensing coupling grating 24 receives and couples the sensing light L1 to the human eye E, the information acquisition module 25 receives the sensing light L1 reflected from the human eye E, and obtains the gaze information of the human eye E. The control module 4 then receives the gaze information of the human eye E and adjusts the display image of the image light L2 according to the gaze information of the human eye E. This can meet the needs of the user and the near-eye display device 100. Compared with the near-eye display device 100 that adopts the traditional interactive technology, the near-eye display device 100 provided by the embodiment of the present application obtains the gaze information of the human eye E, is not prone to the problem of command ambiguity, and is not prone to the situation where recognition failure occurs due to strong light infection; in addition, compared with the display device that obtains the gaze information of the human eye E through an external camera, the near-eye display device 100 of the embodiment of the present application is conducive to reducing the overall weight and volume of the near-eye display device 100, thereby helping to improve the portability of the near-eye display device 100, and further helping to improve the user experience.
