Description

Technical Field

[0001] The present invention relates to the field of naked-eye 3D and 2D technology on the same screen, and more specifically, to a device for realizing naked-eye 3D and 2D multi-window display on the same screen and a control method thereof. Background Art

[0002] With the rapid development of science and technology, naked-eye 3D technology has emerged as a striking technology, which allows users to watch 3D images or videos without wearing any glasses or equipment. Traditional naked-eye 3D display technology is mainly divided into cylindrical lens type and grating type naked-eye 3D display technology. The main technical implementation method is to directly add structures such as cylindrical lenses and gratings to the image source. This method has serious physical resolution loss, high fitting accuracy requirements, strict viewing angle requirements, and the 3D mode is not compatible with the 2D mode. This creates a gap between naked-eye 3D products and actual application needs, and has been slow to enter the application scenarios of home or daily office. Summary of the invention

[0003] One of the purposes of the present invention is to provide a device for realizing naked-eye 3D and 2D multi-window display on the same screen, which can simultaneously realize the naked-eye 3D display and 2D display multi-window state; the second purpose of the present invention is to provide a control method for realizing naked-eye 3D and 2D multi-window display on the same screen.

[0004] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0005] A first aspect of the present invention provides a device for realizing naked-eye 3D and 2D multi-window display on the same screen, comprising a light source and a display screen, and further comprising:

[0006] A first layer of regulating devices, which are arranged between the light source and the display screen and are configured to controllably open or close devices in a specific area, and are used to intercept a light beam in a specific area or allow a light beam in a specific area to pass through;

[0007] An optical lens group, which is disposed between the first-layer regulator and the display screen, and in 3D mode, shapes the light beam passing through the first-layer regulator;

[0008] The second layer of regulating devices is arranged between the optical lens group and the display screen, and the second layer of regulating devices is configured to display 3D display content and 2D display content in different areas at the same time.

[0009] In the above technical solution, two layers of control devices are used, the first layer of control devices is used as a light source control unit, and the second layer of control devices is used as an image source to provide 3D and 2D pictures and videos to the observer. The first layer of control devices controls the light source according to the window information played by the second layer of control devices. The incompatibility problem of 2D and 3D modes is solved. Since the second layer of control devices directly sends the image source to the viewer's eyes, the viewing of 2D and 3D does not lose resolution, the crosstalk is small, and the naked eye 3D display and 2D display multi-window state are realized.

[0010] Furthermore, the first layer of control devices includes a liquid crystal light valve or an electronic grating.

[0011] Furthermore, the optical lens group includes a multi-lens lenticular array structure, a single-lens lenticular array structure, a grating array structure or a liquid crystal lens, wherein the surface types in the multi-lens lenticular array structure and the single-lens lenticular array structure include any one or any combination of a spherical array, an aspherical array and a free-form array, and the optical material of the optical lens group is a polarization-maintaining material.

[0012] Furthermore, the second-layer regulating device includes a color liquid crystal panel.

[0013] A second aspect of the present invention provides a control method for realizing a same-screen naked-eye 3D and 2D multi-window display device, comprising the following steps:

[0014] Determine a 3D display area and a 2D display area according to the 3D display content and the 2D display content on the second-layer regulating device;

[0015] For the 3D display area, the control areas corresponding to the left and right eyes in the corresponding areas of the first layer of control devices are sequentially opened and closed, so that the light beam of the light source passes through, and then through the optical lens group, the 3D content corresponding to the 3D display area on the second layer of control devices is sequentially projected to the left and right eyes to form naked-eye 3D;

[0016] For the 2D display area, all corresponding areas of the first layer of regulating devices are opened to scatter the light beam in all directions, and the 2D display content of the 2D display area on the second layer of regulating devices is displayed in the entire viewing space to form a 2D display.

[0017] Further, determining the 3D display area according to the 3D display content on the second-layer regulating device includes:

[0018] S6.1: Obtain all visible application-related information of the second-layer control device, where the application-related information includes window handle, window title, and coordinate information of window position;

[0019] S6.2: Determine whether there is a 3D application window in the acquired application-related information. If there is a 3D application window, jump to step S6.3; if there is no 3D application window, jump to step S6.7;

[0020] S6.3: Determine whether the current 3D application window is in full screen mode. If it is, jump to step S6.6; if it is not, jump to step S6.4.

[0021] S6.4: Traverse all 3D application windows to obtain window information of all 3D application windows;

[0022] S6.5: determining the window state of the 3D application window according to the window information, and adding the window state of the 3D application window to the 3D application window list;

[0023] S6.6: Determine whether the traversal of the 3D application window is completed. If completed, jump to step S6.7; if not completed, jump to step S6.4;

[0024] S6.7: Performing area coverage determination on the regions of the 3D application windows in the 3D application window list to obtain a final 3D display region.

[0025] Furthermore, in step S6.4, all 3D application windows are traversed to obtain window information of all 3D application windows, including:

[0026] For any 3D application window, the corresponding area of ​​the first-layer control device is opened in real time, all 3D application windows are traversed, and the window information of all 3D application windows is obtained.

[0027] Furthermore, in step S6.7, the area coverage determination is performed on the regions of the 3D application windows in the 3D application window list, including:

[0028] When 3D application windows overlap, the overlapping areas are compared. If the non-overlapping area exceeds 1 / 2 of the 3D application window area, the original 3D application window will be kept. If the non-overlapping area is less than 1 / 2 of the 3D application window area, the 3D application window will be closed.

[0029] Furthermore, step S6.7 further includes step S6.8:

[0030] Track the observer's eyes, and determine whether there is a new 3D application window on the second-layer control device according to the movement of the observer's eyes. If so, obtain application information of the new 3D application window and return to step S6.1.

[0031] Furthermore, the control frequency of the control areas corresponding to the left and right eyes in the corresponding areas of the first-layer control device is not less than 120Hz, and the 3D content of the corresponding 3D display window area on the second-layer control device is loaded with timing, kept synchronized with the first control device, and the refresh frequency is not less than 120Hz.

[0032] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0033] The present invention uses two layers of control devices to solve the incompatibility problem between 2D and 3D modes. Since the second layer of control devices directly sends the image source to the viewer's eyes, the viewing of 2D and 3D does not lose resolution. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The drawings are for illustrative purposes only and should not be construed as limiting the present patent;

[0043] In order to better illustrate the present embodiment, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0044] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0045] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0046] Example 1

[0047] This embodiment provides a device for realizing naked-eye 3D and 2D multi-window display on the same screen, including a light source and a display screen, such as Figure 1 As shown, it also includes:

[0048] A first layer of regulating devices, which are arranged between the light source and the display screen and are configured to controllably open or close devices in a specific area, and are used to intercept a light beam in a specific area or allow a light beam in a specific area to pass through;

[0049] An optical lens group, which is disposed between the first-layer regulator and the display screen, and in 3D mode, shapes the light beam passing through the first-layer regulator;

[0050] The second layer of regulating devices is arranged between the optical lens group and the display screen, and the second layer of regulating devices is configured to display 3D display content and 2D display content in different areas at the same time.

[0051] In this embodiment, two layers of control devices are used, the first layer of control devices is used as a light source control unit, and the second layer of control devices is used as an image source to provide 3D and 2D pictures and videos to the observer. The first layer of control devices controls the light source according to the window information played by the second layer of devices. The incompatibility problem of 2D and 3D modes is solved. Since the second layer of control devices directly sends the image source to the viewer's eyes, the 2D and 3D viewing does not lose resolution.

[0052] In a further embodiment, the first layer of regulating devices includes liquid crystal light valves or electronic gratings.

[0053] In a further embodiment, the optical lens group includes a multi-lens lenticular array structure, a single-lens lenticular array structure, a grating array structure or a liquid crystal lens, wherein the surface types in the multi-lens lenticular array structure and the single-lens lenticular array structure include any one or any combination of a spherical array, an aspherical array and a free-form array, and the optical material of the optical lens group is a polarization-maintaining material.

[0054] In a further embodiment, the second layer regulating device includes a color liquid crystal panel.

[0055] In this embodiment, Figure 2As shown, there is an optical lens group between the two layers of control devices. The optical lens group mainly shapes the light beam of the first layer of control devices in 3D mode. The optical devices of the optical lens group define the number of viewers. When the optical devices of the optical lens group and the light source and viewpoint of the first layer of control devices correspond one to one, multiple people can be supported to watch at the same time within the range allowed by the viewing angle. The second layer of control devices can provide multiple independent 3D windows and 2D windows for multiple people respectively. At the same time, the control device of the first layer opens the control area of ​​3D mode under the 3D window, and the first layer of control devices under the 2D window is in full open mode; when the optical devices of the optical lens group and the light source and viewpoint of the first layer of control devices do not correspond, single-person viewing is supported. In the single-person viewing mode, the 3D window can also provide multiple independent 3D windows and 2D windows, which are accurately projected into the left and right eyes of the observer through the optical devices of the lens group, and crosstalk is controlled. Since the two layers of control devices perform their respective functions separately, the resolution of 2D and 3D maintains the resolution of the second layer of control devices without loss, ensuring the comfort of the viewer when switching between 2D and 3D viewing.

[0056] The above system devices, such as Figure 1 As shown, there is a lens group 3(a) between the two layers of control devices 1(a) and 2(a). The lens group 3(a) is mainly used to shape the light beam of the first layer of control devices in 3D mode. The optical devices of the lens group define the number of viewers. Figure 1 The three-piece optical system and the first-layer control device are in accordance with the periodic correspondence. The number of viewers can support multiple people watching at the same time within the range allowed by the viewing angle, for example Figure 1 For observers 4 and 5, the second-layer regulating device of the display control can provide multiple independent 3D windows and 2D windows for observers 4 and 5 respectively.

[0057] Further, combined with Figure 4 The cross-sectional view of the principle of the two-layer control device of 3D and 2D working simultaneously for multiple people to watch, specifically explained as follows: the second-layer control device 2(a) for simultaneous display control can provide multiple independent 3D windows and 2D windows for multiple people. The first-layer control device 1a turns on the control area 1a(b) of the 3D mode under the 3D window, corresponding to the 3D mode displayed in the observation area; and the 1a(a) and 1a(c) areas of the first-layer control device under the 2D window are in full open mode, corresponding to the 2D mode displayed in the observation area;

[0058] When the first layer of control devices and the lens group covered above have no periodic correspondence, single-person viewing is supported. Figure 3For explanation, there is a lens group 3(b) between the first layer regulating device 1(b) and the second layer regulating device 2(b) in the figure. The lens group 3(b) in the figure adopts a lens group solution, and when there is no periodic corresponding relationship with the first layer regulating device 1(b), it supports viewing by one observer 6. In the single-person viewing mode, the 3D window can also provide multiple independent 3D windows and 2D windows, which are accurately projected into the left and right eyes of the observer through the optical device of the lens group 3(b), and crosstalk is controlled.

[0059] Further, combined with Figure 5 The principle cross-sectional view of the two-layer control device of 3D and 2D working at the same time for a single person to watch, specifically explained as follows: the second-layer control device 2(b) for simultaneous display control can provide multiple independent 3D windows and 2D windows for a single person. The first-layer control device 1(b) turns on the 3D mode in the 3D window. The control area 1b(b) corresponds to the 3D mode displayed in the observation area; and the 1b(a) and 1b(c) areas of the first-layer control device under the 2D window are in full open mode, corresponding to the 2D mode displayed in the observation area;

[0060] Since the two layers of control devices perform their respective functions separately, the resolution of 2D and 3D remains the resolution of the second layer of control devices without loss, ensuring the comfort of viewers when switching between 2D and 3D viewing.

[0061] Example 2

[0062] This embodiment provides a control method for realizing the same-screen naked-eye 3D and 2D multi-window display device according to Embodiment 1, such as Figure 6 As shown, the following steps are included:

[0063] Determine a 3D display area and a 2D display area according to the 3D display content and the 2D display content on the second-layer regulating device;

[0064] For the 3D display area, the control areas corresponding to the left and right eyes in the corresponding areas of the first layer of control devices are sequentially opened and closed, so that the light beam of the light source passes through, and then through the optical lens group, the 3D content corresponding to the 3D display area on the second layer of control devices is sequentially projected to the left and right eyes to form naked-eye 3D;

[0065] For the 2D display area, all corresponding areas of the first layer of regulating devices are opened to scatter the light beam in all directions, and the 2D display content of the 2D display area on the second layer of regulating devices is displayed in the entire viewing space to form a 2D display.

[0066] In a further embodiment, the control frequency of the control areas corresponding to the left and right eyes in the corresponding areas of the first layer of control devices is not less than 120Hz, and the 3D content corresponding to the 3D display window area on the second layer of control devices is loaded with timing, kept synchronized with the first control device, and the refresh frequency is not less than 120Hz.

[0067] In a specific embodiment, when an observer simultaneously watches 3D and 2D content on the same screen with naked eyes, the first-layer control device sequentially opens and closes the control areas corresponding to the left and right eyes in the corresponding 3D display area, and the control frequency is not less than 120Hz. The first-layer control device keeps the control area in the corresponding 2D content display area in a long-light state without refreshing. The second-layer control device loads the 3D content in the corresponding 3D display window area in a sequential manner, keeps it synchronized with the first control device, and the refresh frequency is not less than 120Hz. The corresponding 2D display area on the second-layer control device is added to the 2D display content.

[0068] Example 3

[0069] This embodiment further describes the method for controlling the same-screen naked-eye 3D and 2D multi-window display device of Embodiment 2, and determines the 3D display area according to the 3D display content on the second-layer control device, such as Figure 7 As shown, including:

[0070] S6.1: Obtain all visible application-related information of the second-layer control device, where the application-related information includes window handle, window title, and coordinate information of window position;

[0071] S6.2: Determine whether there is a 3D application window in the acquired application-related information. If there is a 3D application window, jump to step S6.3; if there is no 3D application window, jump to step S6.7;

[0072] S6.3: Determine whether the current 3D application window is in full screen mode. If it is, jump to step S6.6; if it is not, jump to step S6.4.

[0073] S6.4: Traverse all 3D application windows to obtain window information of all 3D application windows;

[0074] S6.5: determining the window state of the 3D application window according to the window information, and adding the window state of the 3D application window to the 3D application window list;

[0075] S6.6: Determine whether the traversal of the 3D application window is completed. If completed, jump to step S6.7; if not completed, jump to step S6.4;

[0076] S6.7: Performing area coverage determination on the regions of the 3D application windows in the 3D application window list to obtain a final 3D display region.

[0077] In a further embodiment, in step S6.4, all 3D application windows are traversed to obtain window information of all 3D application windows, including:

[0078] For any 3D application window, the corresponding area of ​​the first-layer control device is opened in real time, all 3D application windows are traversed, and the window information of all 3D application windows is obtained.

[0079] In a further embodiment, performing area coverage determination on the regions of the 3D application windows in the 3D application window list in step S6.7 includes:

[0080] When 3D application windows overlap, the overlapping areas are compared. If the non-overlapping area exceeds 1 / 2 of the 3D application window area, the original 3D application window will be kept. If the non-overlapping area is less than 1 / 2 of the 3D application window area, the 3D application window will be closed.

[0081] like Figure 8 As shown in (a), the target 3D window is covered by other windows (including 2D and 3D windows). When the remaining area of ​​the target 3D window after being covered exceeds half of the total area of ​​the target 3D window, it is determined to be a valid 3D window.

[0082] like Figure 8 As shown in (b), the target 3D window is covered by other windows (including 2D and 3D windows). When the remaining area of ​​the target 3D window after being covered is less than half of the total area of ​​the target 3D window, it is judged as an invalid 3D window. Only valid 3D windows will enable 3D in the corresponding area, otherwise it will not be enabled.

[0083] In a further embodiment, step S6.7 further includes step S6.8:

[0084] Track the observer's eyes, and determine whether there is a new 3D application window on the second-layer control device according to the movement of the observer's eyes. If so, obtain application information of the new 3D application window and return to step S6.1.
