Description
Technical Field

[0002] VR (Virtual Reality) products have developed rapidly in recent years, and various new products have emerged in an endless stream. However, the visible area (field of view) and the visible image quality (clarity) of current virtual reality products on the market are restricted. It is very difficult to improve both the field of view of virtual reality products and the clarity of the visible images of users on the basis of existing technologies. The reason is that the screens used in current virtual reality products cannot ensure that the central field of view is clear while the peripheral field of view is also clear. Therefore, when designing a virtual reality product, optical design engineers always make the central field of view of the image clearer while the peripheral field of view is barely clear, and find a balance between the two. The final result is that the central clarity and image quality of the product display image are significantly higher than the clarity and image quality of the peripheral field of view image. Moreover, there may be a situation where the clarity of the central field of view image can be further improved, but in order to take into account the clarity of the peripheral field of view, the depth optimization has to be abandoned. Therefore, due to the influence of different optical path differences between different light-emitting points on the screen plane and the lens, the above problems always exist and become an important obstacle affecting the further development of virtual display products.

[0032] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0033] Refer to Figure 1 , Figure 1 It is a schematic structural diagram of the operating device of the hardware operating environment involved in the solution of the embodiment of the present application.
[0034] As Figure 1 shown, the operating device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.
[0035] Those skilled in the art can understand that Figure 1 the structure shown in
[0036] does not constitute a limitation on the operating device, and may include more or fewer components than shown in the figure, or combine some components, or arrange different components. Figure 1As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a computer program.
[0037] In Figure 1 In the operating device shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with users; the processor 1001 and the memory 1005 in the operating device of the present application may be provided in the operating device, and the operating device calls the computer program stored in the memory 1005 through the processor 1001 and performs the following operations:
[0038] Move the pixel block of the display screen along the optical path direction;
[0039] Perform content display based on the display screen after adjusting the pixel block.
[0040] In an embodiment, the processor 1001 may call the computer program stored in the memory 1005 and further perform the following operations:
[0041] The step of moving the pixel block of the display screen along the optical path direction includes:
[0042] Determine the area to be adjusted based on the image display clarity of the display screen;
[0043] Move the pixel block of the display screen along the optical path direction for the pixels in the area to be adjusted until the image display clarity reaches the best clarity of the display screen.
[0044] The embodiment of the present application provides a pixel block adjustment device. Referring to Figure 2 , in an embodiment of the pixel block adjustment device, the pixel block adjustment device includes:
[0045] A lifting and moving mechanism for moving the pixel block back and forth along the optical path direction when the pixel block is not locked and fixed;
[0046] A locking and fixing mechanism for locking and fixing the pixel block in the direction perpendicular to the optical path.
[0047] The pixel block can have various spatial postures as the user uses it. In the following, the case where the pixel block is vertically placed will be taken as an example for illustration. Among them, when it is vertically placed, the optical path direction of the pixel block is the up-down direction. The locking mechanism for fixing the pixel block locks and fixes the pixel block by lateral expansion and contraction, preventing displacement changes such as up-down or left-right of the pixel block when it is fixed. The lifting mechanism moves the pixel block up and down when the pixel block is not locked and fixed, changing the up-down position of the pixel block, so that on the premise of ensuring the safety of the pixel block, without being squeezed or worn, each pixel can undulate up and down on the plane where the original pixel is located, improving the imaging quality of the overall image by changing the distance between each pixel and the lens of the virtual reality product and changing the optical path of each light-emitting point imaging in the optical path of the virtual reality product, and can further improve the imaging clarity of the virtual reality product. Thus, in the design and debugging stages such as when designing the optics of the virtual reality product and during production verification, the imaging quality of the virtual reality product can be effectively improved. On the basis of not affecting the overall optical scheme of the machine (Fresnel or ultra-short focal optical folding optical path pancake), it is ensured that both the central area and the edge area of the virtual reality display screen achieve the best display effect, and the imaging quality and clarity of the virtual reality product are further improved. It should be noted that in order to ensure the best display effect of the virtual reality product in the design, production, and debugging stages before leaving the factory, the function of adjusting the up-down position of the pixel block is not opened to the user during the actual use process after the product is delivered.
[0048] Exemplarily, both the locking and fixing mechanism and the lifting and moving mechanism are magnetic components.
[0049] Among them, the locking and fixing mechanism for fixing the pixel block and the lifting and moving mechanism for moving the pixel block up and down are both magnetic components. Based on the electromagnetic effect, by changing the current flowing through the locking and fixing mechanism and the lifting and moving mechanism, the electromagnetic force of the magnetic components is changed, and then the pixel block is fixed and the pixel block is moved up and down in a non-contact manner.
[0050] Exemplarily, the locking and fixing mechanism includes: a first electromagnet group located on the left side of the pixel block, and a second electromagnet group located on the right side of the pixel block. The locking forces generated by the first electromagnet group and the second electromagnet group are balanced forces.
[0051] The first electromagnet group of the locking and fixing mechanism is located on the left side of the pixel block, and the second electromagnet group of the locking and fixing mechanism is located on the right side of the pixel block. The locking forces generated by the first electromagnet group and the second electromagnet group are balanced forces and both act on the pixel block, thus realizing the fixation of the pixel block in a non-contact manner.
[0052] Exemplarily, the electromagnet group includes a first electromagnet that moves back and forth along the optical path direction together with the pixel block, and a second electromagnet fixed on a preset fixed block parallel to the optical path direction of the pixel block.
[0053] The electromagnet group therein includes a first electromagnet that moves up and down together with the pixel block, and a second electromagnet fixed on a preset fixed block on the side of the pixel block. Among them, the preset fixed block can be the second electromagnet itself vertically fixed on the base of the pixel block. In this embodiment, the method of fixing the electromagnet to the pixel block is not limited. In one embodiment, the first electromagnet and the second electromagnet are two vertically parallel electromagnets, and the length of the first electromagnet is shorter than that of the second electromagnet, so that the pixel block can be fixed no matter what height it is moved up and down to.
[0054] Exemplarily, the lifting and moving mechanism includes: a third electromagnet that moves back and forth along the optical path direction together with the pixel block, and a fourth electromagnet fixed on the base of the pixel block.
[0055] Similarly, the lifting and moving mechanism includes a third electromagnet that moves up and down together with the pixel block, and a fourth electromagnet fixed on the base of the pixel block.
[0056] In one embodiment, referring to Figure 2 , where 1 is a single pixel block, 2 is the second electromagnet in the first electromagnet group or the second electromagnet group, 3 is the first electromagnet in the electromagnet group, 4 is the third electromagnet of the lifting and moving mechanism, and 5 is the fourth electromagnet of the lifting and moving mechanism. In the initial state, both the electromagnet 4 and the electromagnet 5 are in the non-powered state, that is, neither of them has magnetism. The pixel block 1 is locked and fixed by the locking and fixing mechanism 2 at the default position and cannot move up and down temporarily. When it is necessary to adjust the undulation of the pixel block 1, the electromagnet 4 and the electromagnet 5 are powered on. Different magnitudes of the current flowing through the electromagnet 4 and the electromagnet 5 will cause the pixel block 1 to have a tendency to move upward or downward. In this embodiment, the magnetic force is set as a repulsive force. By adjusting the magnitude of the repulsive force (current) between the two poles of the electromagnet, the pixel block 1 can be moved upward or downward. After the electromagnet 4 and the electromagnet 5 are powered on, the locking and fixing mechanism 2 is unlocked, and the pixel block 1 moves upward or downward a certain distance under the action of the magnetic force. Until the pixel block 1 is adjusted to the ideal position, the locking and fixing mechanism 2 is locked to fix the pixel block 1 at the adjusted ideal position. Finally, the electromagnet 4 and the electromagnet 5 are powered off, and the adjustment is completed.
[0057] The embodiment of the present application provides a virtual reality display screen, which is composed of pixel blocks, and each pixel block is adjusted by the above-mentioned pixel block adjustment device.
[0058] Most of the light-emitting screens of virtual reality products currently on the market are rectangular flat screens or polygonal flat screens. The light carrying image information emitted by the screen enters the human eye after passing through a lens. Due to the refraction effect of the lens on the light, the center of the image is the clearest. When transitioning from the center to the edge, the distortion and distortion of the image will increase significantly, affecting the user's viewing experience during use. In the optical design engineer's simulation optical path design of virtual reality products, the screen is defaulted to be flat, which will result in poor imaging quality in the edge field of view when the central field of view image of the screen is clear during the design process, and poor central image field of view when the edge field of view image quality is good. The final design result is that the imaging quality of the central field of view and the edge field of view of the image displayed on the screen are both lower than the best value that can be achieved theoretically, which is a balance between the two.
[0059] If the distance between each pixel point (i.e., the light-emitting point) on the screen and the lens designed for virtual reality products changes, the imaging quality of the VR product can be significantly improved during the initial optical path design, which helps optical design engineers correct the aberrations, distortions, field curvatures, chromatic aberrations, etc. of the overall image during the initial design. During actual assembly and testing, the height of the pixel points in the area where the imaging on the screen is not clear can also be dynamically adjusted to further improve the imaging quality and clarity of virtual reality products.
[0060] Compared with other flat screens, the display screen in this embodiment will have an increase in size and thickness of about 15 mm. The increased thickness area is the lifting mechanism of the pixel points in the screen and the reserved adjustable distance of the pixel points. Each pixel point on the screen is divided into a tiny small square, and under the square is a telescopic mechanism for adjusting the height of the pixel points. With the matching software and algorithms, after computer analysis and control, a single pixel point or a pixel point matrix in the target area will be raised or lowered by a certain distance, and its adjustment method is automatic adjustment.
[0061] In this embodiment, a virtual reality display screen is proposed, in which each pixel point on the screen can undulate up and down on the plane where the original pixel point is located. By changing the distance between each pixel point on the screen and the lens of the VR product, that is, changing the optical path of each light-emitting point imaging in the optical path of the VR product, the imaging quality of the overall image is improved. The initial state of the screen is a whole flat screen, but each pixel point contained in it can be displaced up and down by ±6 mm depending on the tiny adjustment mechanism below it. The displacement method is magnetic displacement. By controlling the voltage magnitude of each magnetic lifting mechanism through software, a single pixel point can be displaced up or down relative to the initial plane.
[0062] The embodiment of the present application provides a display adjustment method. Referring to Figure 3 , in an embodiment of the display adjustment method, the method is applied to the virtual reality display screen as described above, including:
[0063] Step S10, move the pixel block of the display screen along the optical path direction;
[0064] Step S20, perform content display based on the display screen after adjusting the pixel block.
[0065] Each pixel can be adjusted up and down on the plane where the original pixel is located. By changing the distance between each pixel and the lens of the virtual reality product and changing the optical path of each light-emitting point imaging in the optical path of the virtual reality product, the imaging quality of the overall image is improved. And content display is performed based on the display screen after adjusting the height of the pixel block, so as to further improve the imaging clarity of the virtual reality product. Thus, during the design and debugging stages such as the optical design and production verification of the virtual reality product, the imaging quality of the virtual reality product is effectively improved. On the basis of not affecting the overall optical scheme of the machine, it is ensured that both the central area and the edge area of the virtual reality display screen reach the best display effect, and the imaging quality and clarity of the virtual reality product are further improved.
[0066] Exemplarily, the step of moving the pixel block of the display screen along the optical path direction includes:
[0067] Step S10A, determine the area to be adjusted based on the image display clarity of the display screen;
[0068] Step S10B, move the pixel block of the display screen along the optical path direction for the pixels in the area to be adjusted until the image display clarity reaches the best clarity of the display screen.
[0069] The determination of the area to be adjusted needs to be automatically determined by an algorithm based on the image clarity, and the height of the pixels corresponding to the unclear image is adjusted, that is, the pixels in the area to be adjusted are adjusted up and down. When the algorithm detects that the image in the area to be adjusted has reached the highest clarity, stop adjusting the pixels in the area to be adjusted up and down.
[0070] Exemplarily, the step of determining the area to be adjusted based on the image display clarity of the display screen includes:
[0071] Determine the area to be adjusted by comparing the theoretical clarity and the actual clarity of the image currently displayed on the display screen.
[0072] Exemplarily, the step of adjusting the pixels in the area to be adjusted up and down includes:
[0073] After determining that the actual clarity of the image displayed on the display screen is less than the theoretical clarity, raise the pixel points in the area to be adjusted; after determining that the actual clarity is less than the theoretical clarity again after raising the actual clarity, lower the pixel points in the area to be adjusted.
[0074] The determination of the area to be adjusted depends on the algorithm to compare the theoretical clarity of the image currently displayed on the display screen with the actual clarity of the displayed image, and then automatically determines the area to be adjusted corresponding to the unclear part of the image. In this embodiment, the strategy of raising and lowering the pixel points up and down in the area to be adjusted is as follows: after determining that the actual clarity of the image displayed on the display screen is less than the theoretical clarity, raise the pixel points in the area to be adjusted; after determining that the actual clarity of the image displayed on the display screen is less than the theoretical clarity again after the default operation step of raising the pixel points in the area to be adjusted. Then, lower the pixel points in the area to be adjusted. Thus, the image in the area to be adjusted is adjusted to the highest clarity. When the algorithm detects that the image in the area to be adjusted has reached the highest clarity, stop adjusting the pixel points in the area to be adjusted up and down.
[0075] Exemplarily, after the step of until the display clarity of the image reaches the best clarity of the display screen, it further includes:
[0076] Obtain the target adjustment area and the target action for adjusting the target adjustment area, and adjust the pixel points up and down in the target adjustment area based on the target action.
[0077] In addition to determining the area to be adjusted by comparing the clarity through the algorithm and adjusting the area to be adjusted, considering that the algorithm cannot be completely correct, there is a probability of misjudgment and error, and the algorithm setting is unreasonable and does not conform to the user's eye viewing experience, etc. In this embodiment, first, obtain the target adjustment area and the target action for adjusting the target adjustment area, and adjust the pixel points up and down in the target adjustment area based on the target action. Exemplarily, you can choose to manually input the area where you want to adjust the ups and downs of the pixel points in the software, and then input the positive and negative height values generated relative to the original plane. The algorithm can automatically adjust the height difference between each pixel point through the dynamic adjustment mechanism under a single pixel point of the screen.
[0078] In this embodiment, each pixel point of the display screen of the virtual reality display device can be raised and lowered. The pixel points of the display screen are adjusted up and down, and the content is displayed based on the display screen after adjusting the pixel point height.
[0079] Each pixel on the display screen can undulate up and down on the plane where the original pixel is located. By changing the distance between each pixel on the display screen and the lens of the virtual reality product, that is, changing the optical path of each light-emitting point imaging in the optical path of the virtual reality product, the imaging quality of the overall image can be improved, which can further enhance the imaging clarity of the virtual reality product, providing new ideas for optical designers during design, and innovatively solving the problem that currently restricts the further improvement of image quality. Through the undulation of each pixel in the screen, the image display screen can be dynamically adjusted, improving the output image quality of the virtual reality product, making the optical display effect of the virtual reality product more realistic, and giving users a more realistic virtual reality experience.
[0080] Therefore, during the design and debugging stages such as the optical design and production verification of virtual reality products, the imaging quality of virtual reality products can be effectively improved. On the basis of not affecting the overall optical scheme of the machine (Fresnel or ultra-short focal length optical folded optical path pancake), it is ensured that both the central area and the edge area of the virtual reality display screen reach the best display effect, and the imaging quality and clarity of the virtual reality product are further improved.
[0081] Refer to Figure 5 , in addition, the embodiment of the present application also provides a display adjustment device, and the display adjustment device includes:
[0082] Adjustment module M1, used to move the pixel block of the display screen along the optical path direction;
[0083] Application module M2, used to display content based on the display screen after adjusting the pixel block.
[0084] Exemplarily, the adjustment module is further used to:
[0085] Determine the area to be adjusted based on the image display clarity of the display screen;
[0086] Move the pixel block of the display screen along the optical path direction for the pixels in the area to be adjusted until the image display clarity reaches the best clarity of the display screen.
