[0031] Figure 1 The diagram shown is a flowchart of a stereoscopic display method according to an embodiment of this application. The execution subject of this method can be a display device, and the method is applicable to a display panel in the display device. The display panel includes an optical fiber cover plate and a deformable layer. The deformable layer is attached to the surface of the optical fiber cover plate near the light-incident side. The optical fiber cover plate is composed of a predetermined number of optical fiber units, such as... Figure 1 As shown, the above-mentioned stereoscopic display method may include the following steps:

[0032] Step S101: Obtain the image to be displayed on the light-incident side of the optical fiber cover plate, divide the image to be displayed into regions, and obtain each target region.

[0033] In this embodiment, the display device divides the current image to be displayed into regions to facilitate regional processing of the image, thereby improving the display effect. The aforementioned fiber optic cover is a panel within the display panel capable of planar image transmission. The preset number of fiber optic units constituting the fiber optic cover can be of equal size or, depending on requirements, of unequal size. For example, a fiber optic cover composed of N rows and M columns of equally sized fiber optic units, where N and M are both positive integers greater than 1. Figure 2 As shown, Figure 2 This is a schematic diagram of the fiber optic cover plate. Figure 2 The area enclosed by the dotted circle is the fiber optic cover plate 2, which is composed of 4 rows and 4 columns of equally sized fiber optic units 22, and each fiber optic unit is composed of a predetermined number of optical fibers 21.

[0034] In one embodiment, since the area of ​​the image to be displayed is the same as the area of ​​the fiber optic cover plate, in order to facilitate the control of the target areas after the image to be displayed is divided, step S101 may include: the display device divides the image to be displayed into areas according to the number of fiber optic units that make up the fiber optic cover plate. The display image can be equally divided into target areas of the same size. For example, the display device can divide the image into areas of the same size. Figure 2 The fiber optic cover plate, composed of 16 fiber optic units, is divided into 8 target areas of the same size. The display device can also divide the image to be displayed into areas according to its position to improve the image display effect. For example, the area located at the edge of the image to be displayed is divided into one fiber optic unit, that is, one target area at the edge corresponds to one fiber optic unit.

[0035] In one embodiment, to achieve more precise fiber optic control and make the stereoscopic effect of the displayed image more realistic, step S101 may include: the display device determining the pixels of the image to be displayed, dividing the image into regions based on the pixels, wherein the pixels are arranged relative to the fiber optic unit, i.e., one fiber optic unit corresponds to at least one pixel. Accordingly, for precise control, regions can be divided based on the minimum designable size of the fiber optic unit and the pixel size. Generally, the minimum designable size of the fiber optic unit is within the range of 1 to 3 times the pixel size. Therefore, regions are divided according to the relative multiples of the pixels to obtain regions whose size is consistent with the relative multiples of the pixels, i.e., regions consistent with the size of the fiber optic unit. For example, three pixels in the image to be displayed can be divided into one region.

[0036] In one embodiment, since the display device divides the image to be displayed into regions to improve the display effect, and the display effect of the same object in the image is relatively consistent, step S101 may include: the display device performing image recognition on the image to be displayed using an image recognition algorithm to determine at least one target object in the image to be displayed, so as to divide the image to be displayed into regions based on the target object. The target object can be any object in the image other than the background, such as a bird in the sky, where the sky is part of the background.

[0037] Specifically, the display device can divide the area by determining the fiber optic units occupied by the target object. For example, if a bird in the image to be displayed occupies two fiber optic units, then those two fiber optic units are divided into the target area.

[0038] Furthermore, if at least two target objects occupy a fiber optic unit, then the target object occupying the largest area is selected from the at least two target objects, and the fiber optic unit is assigned to the target region corresponding to the target object occupying the largest area.

[0039] In one embodiment, since the side of the object relative to the image acquisition device is not perfectly planar, to improve the accuracy of the target object relative to the real scene in the image, after dividing the image to be displayed into regions based on the target object, the method may further include: if the number of fiber optic units corresponding to the divided regions is greater than a preset threshold, it indicates that the region corresponding to the target object is too large. In this case, the divided regions are then divided equally according to the number of fiber optic units to improve the accuracy of the target object relative to the real scene. For example, if there is a pyramid in the image to be displayed, and the number of fiber optic units corresponding to the region divided according to the pyramid is 20, while the preset threshold is 15, it indicates that the number of fiber optic units corresponding to the divided regions is greater than the preset threshold. In this case, the 20 fiber optic units corresponding to the pyramid region can be equally divided into 10 target regions, that is, each target region corresponds to two fiber optic units.

[0040] Step S102: Determine the image depth of each target region.

[0041] In this embodiment, the display device can determine the image depth of each target area by using deep learning to estimate the distance using monocular vision depth estimation.

[0042] Step S103: Control the deformation layer corresponding to each target area according to the image depth of each target area, so that the deformation layer drives the fiber unit to deform.

[0043] In this embodiment, the display device controls the fiber optic units corresponding to each target area to deform according to the image depth corresponding to each target area, so that the height positions of different areas of the fiber optic cover plate corresponding to the image to be displayed are different, resulting in different distances between the displayed image and the viewer, thereby solving the problem that the fiber optic cover plate can only transmit images in a planar plane and has no sense of three-dimensionality.

[0044] Step S104: Display the image to be displayed on the deformed fiber optic cover plate.

[0045] In this embodiment, the display device displays the image to be displayed on the deformed optical fiber cover plate, so that the image to be displayed on the light-incident side of the light panel composed of the deformed optical fiber units has a three-dimensional effect in space, thereby improving the display effect when the image to be displayed is displayed.

[0046] In one embodiment, the aforementioned deformable layer comprises a piezoelectric ceramic thin film, such as... Figure 3 As shown, Figure 3The area enclosed in the dashed circle represents the piezoelectric ceramic film 3. The piezoelectric ceramic film 3 is composed of a predetermined number of film units 31 positioned opposite the optical fiber units. The piezoelectric ceramic film 3 is the moving film in the display panel. The predetermined number of film units constituting the piezoelectric ceramic film can be film units of equal size or, depending on requirements, film units of unequal size. These film units correspond to the aforementioned optical fiber units. For example, a piezoelectric ceramic film composed of N rows and M columns of film units of equal size, where N and M are both positive integers greater than 1. Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a piezoelectric ceramic thin film. Figure 3 The piezoelectric ceramic thin film 3 is composed of 4 rows and 4 columns of thin film units 31 of equal size.

[0047] Step S103 above may include: the display device determines the target voltage of the thin film unit corresponding to the target area based on the image depth of the target area. Since the thin film unit corresponds to the optical fiber unit, the target area corresponds to at least one thin film unit. Based on the inverse piezoelectric effect of the piezoelectric ceramic thin film, the display device inputs the target voltage to the thin film unit corresponding to the target area to cause the thin film unit to generate mechanical vibration of contraction or expansion according to the input voltage. The amount of contraction and expansion is positively correlated with the absolute value of the voltage. The sign of the voltage determines whether the thin film unit is currently performing contraction vibration or expansion vibration, thereby controlling the thin film unit to push the optical fiber unit to deform, that is, move upward or downward.

[0048] In one embodiment, the display panel further includes a protective film disposed on the upper layer of the fiber optic cover plate to protect the fiber optic cover plate. The fiber optic cover plate is disposed between the protective film and the piezoelectric ceramic film; that is, the upper layer of the display panel is the protective film, the middle layer is the fiber optic cover plate, and the lower layer is the piezoelectric ceramic film. Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a display panel composed of a protective film, an optical fiber cover, and a piezoelectric ceramic film. The protective film can be a transparent, elastic film.

[0049] In one embodiment, determining the target voltage based on the image depth of the target area may include: the display device determining the mean and mode based on the image depth of each target area, and then calculating the difference between the mean and the mode to perform a comprehensive analysis of the image depth of each target area, thereby selecting the most suitable voltage determination method for each target area based on the analysis results, that is, determining the corresponding voltage determination method based on the difference, and finally determining the corresponding target voltage from the voltage determination method based on the image depth of the target area.

[0050] In one embodiment, the method of determining the corresponding voltage based on the difference may include: the display device associating the maximum and minimum values ​​in the image depth of each target area with the maximum and minimum values ​​of the piezoelectric ceramic film voltage to determine the target voltage range.

[0051] When the difference is within the preset threshold range, the voltage determination method is to linearly determine the target voltage based on the target voltage range. The linear determination method can be to determine a target line segment based on the target voltage range and then determine the voltage using linear interpolation based on the target line segment.

[0052] When the above difference is not within the preset threshold range, if the target voltage is determined solely based on the target voltage range, the value of the target voltage will deviate too much from the actual value. Therefore, it is necessary to further limit the target voltage determination range. That is, the voltage determination method is to determine the target voltage by dividing it into segments linearly based on the mode and the target voltage range. The above segment linear determination method can be to determine two target segments respectively based on the two endpoints corresponding to the mode and the target voltage range, and then determine the voltage by linear interpolation based on these two target segments.

[0053] For example, such as Figure 5 As shown, if the maximum value of the image depth of each target region is A, the minimum value of the image depth of each target region is B, the maximum value of the piezoelectric ceramic film voltage is V, and the minimum value of the piezoelectric ceramic film voltage is -V, then the target voltage range is the range between the endpoint (-V, B) and the endpoint (V, A). For example, the target voltage range can be defined by the rectangle formed by the endpoints (-V, B) and (V, A).

[0054] When the mode of the image depth of each target region is E, and the average of the image depth of each target region is C, and the difference is determined to be within a preset threshold range, a target line segment is determined based on the two endpoints that make up the target voltage range. Figure 5 The solid line segment in the middle, from Figure 5 The target voltage corresponding to the image depth is determined on the solid line segment in the image. For example, if the image depth of a certain target area is (A+B) / 2, then the piezoelectric ceramic film voltage corresponding to the target area is (VV) / 2, which is 0V.

[0055] When the mode of the image depth of each target region is D or F, and the average of the image depth of each target region is C, and the above difference is determined to be outside the preset threshold range, then two target line segments can be determined based on the mode D or F and the two endpoints corresponding to the target voltage range. For example, the two dashed line segments corresponding to the mode D, namely the line segment between D and endpoint (-V, B) and the line segment between D and endpoint (V, A), can be determined from... Figure 5The target voltage corresponding to the image depth is determined on the two dashed line segments corresponding to the mode D in the image. For example, if the image depth of a certain target area is (A+D) / 2, then the piezoelectric ceramic film voltage corresponding to that target area is V / 2.

[0056] It is understandable that regions with a relatively large image depth relative to the average are considered background regions in the image, while regions with a relatively small image depth relative to the average are considered foreground regions.

[0057] In one embodiment, to make the deformation of the fiber optic cover conform to the visual effect, after determining the target voltage based on the image depth of the target area, the method may further include: the display device determining the voltage difference between adjacent target areas, and comparing the determined voltage difference with a preset voltage threshold. When the voltage difference is greater than the preset voltage threshold, it indicates that the deformation between adjacent areas is too large, and adaptive adjustments need to be made to the deformation of adjacent areas to make the displayed image more visually appealing. Therefore, the display device determines the arrangement of each thin-film unit in the adjacent target areas, and adjusts the target voltage of each thin-film unit sequentially according to the arrangement to obtain the target voltage corresponding to each thin-film unit. For example, the target voltage of each thin-film unit in the adjacent target areas... The thin film units are arranged in a row, with target region A (target voltage 0.8V) at the front (including thin film unit 1, thin film unit 2, and thin film unit 3) and target region B (target voltage 0.3V) at the back (including thin film unit 4, thin film unit 5, and thin film unit 6). Based on this arrangement and the voltage difference between target regions A and B, the target voltage of each thin film unit can be adjusted sequentially. That is, the target voltage of thin film unit 1 remains 0.8V, the target voltage of thin film unit 2 can be 0.7V, the target voltage of thin film unit 3 can be 0.6V, the target voltage of thin film unit 4 can be 0.5V, the target voltage of thin film unit 5 can be 0.4V, and the target voltage of thin film unit 6 remains 0.3V.

[0058] Accordingly, the target voltage of each target region is input into the corresponding thin film unit of each target region, including: inputting the target voltage of each thin film unit to each thin film unit so as to cause each thin film unit to drive the corresponding optical fiber unit to deform.

[0059] In one embodiment, the piezoelectric ceramic film can also be used as a pressure-sensitive touch film in a display panel. That is, the film unit in the piezoelectric ceramic film can sense finger pressure and generate a corresponding voltage to control the deformation of the corresponding optical fiber unit. The display panel also includes ordinary glass or optical fiber cover for display, such as piano keys, to simulate the touch of practicing the piano, providing an immersive experience and improving efficiency.

[0060] In this embodiment, an image to be displayed on the light-incident side of the aforementioned optical fiber cover is acquired. This image is then divided into regions to obtain target regions, which are then processed separately. The image depth of each target region is determined, allowing for adjustments to the image display based on the varying image depths. Specifically, the deformation layer corresponding to each target region is controlled according to its image depth, causing the deformation layer to push the optical fiber unit to deform. The resulting image is then displayed on the deformed optical fiber cover, achieving a three-dimensional display on the display panel and improving the display effect of the display device.

[0061] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0089] The first method determines the sub-unit, which is used to determine the voltage determination method when the difference is within a preset threshold range. The voltage determination method is a linear determination of the target voltage based on the target voltage range.

[0090] The second method for determining sub-units is used when the difference is not within a preset threshold range. The voltage determination method is to determine the target voltage by dividing it into segments linearly based on the mode and the target voltage range.
