[0030] For the purpose, technical solutions and advantages of the present application to be clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] The terms "first", "second", and the like in the specification of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.

[0032] In the related art, as shown in Figure 1 , integrated imaging generally uses a single-layer display panel as a content source, and only one layer in space can serve as a main imaging plane, so the total depth of field of imaging is limited. In order to solve this problem and improve the imaging effect, as shown in Figure 2 , two sets of integrated imaging devices with different imaging distances can be combined together by using a half-mirror half-transmission lens to obtain a three-dimensional display effect with extended depth of field. However, this method is difficult to assemble and align.

[0033] In view of the above technical problems existing in the related art, the embodiments of the present application provide an integrated imaging system based on multi-layer atomized liquid crystal, as shown in Figure 3 , the system comprises a liquid crystal panel for loading a to-be-displayed image, a lens array, a multi-layer atomized liquid crystal located between the liquid crystal panel and the lens array, and an imaging control unit. As shown in Figure 3 , the main difference between the integrated imaging system based on multi-layer atomized liquid crystal in the present application and the imaging system in the related art is that a multi-layer atomized liquid crystal is added between the liquid crystal panel and the optical device array (i.e. the lens array mentioned above).

[0034] As shown in FIG. 1, a schematic diagram of a multi-layered liquid crystal is shown. The multi-layered liquid crystal can be divided into a plurality of sub-blocks, and each sub-block can be independently fogged. Parallel light rays can be scattered after passing through the fogged sub-blocks, and the parallel light rays can not be scattered after passing through the non-fogged (i.e., transparent) sub-blocks. Figure 4

[0035] As shown in FIG. 1, a schematic diagram of a multi-layered liquid crystal is shown. The multi-layered liquid crystal can be divided into a plurality of sub-blocks, and each sub-block can be independently fogged. Parallel light rays can be scattered after passing through the fogged sub-blocks, and the parallel light rays can not be scattered after passing through the non-fogged (i.e., transparent) sub-blocks.

[0036] As shown in FIG. 1, a schematic diagram of a multi-layered liquid crystal is shown. The multi-layered liquid crystal can be divided into a plurality of sub-blocks, and each sub-block can be independently fogged. Parallel light rays can be scattered after passing through the fogged sub-blocks, and the parallel light rays can not be scattered after passing through the non-fogged (i.e., transparent) sub-blocks. Figure 5

[0037] As shown in FIG. 1, a schematic diagram of a multi-layered liquid crystal is shown. The multi-layered liquid crystal can be divided into a plurality of sub-blocks, and each sub-block can be independently fogged. Parallel light rays can be scattered after passing through the fogged sub-blocks, and the parallel light rays can not be scattered after passing through the non-fogged (i.e., transparent) sub-blocks.

[0038] ​​It should be noted that after the image to be displayed is obtained, firstly, the imaging depth of each part in the image is determined, then the part images are matched with the blocks in the fogging liquid crystal, and finally it is determined which block of which layer of the fogging liquid crystal displays each part of the image.

[0039] Exemplarily, the fogging liquid crystal comprises: a first mode and a second mode; the imaging control unit is specifically configured to control the fogging liquid crystal to fog by applying a voltage when the fogging liquid crystal is in the first mode; and the imaging control unit is specifically further configured to control the fogging liquid crystal to fog by canceling the voltage applied on the fogging liquid crystal when the fogging liquid crystal is in the second mode.

[0040] Exemplarily, the fogging liquid crystal is a liquid crystal of a special material, which is divided into a normal mode and a non-normal mode (i.e. the first mode and the second mode described above), as shown in FIG. 1, which is a fogging schematic diagram of the fogging liquid crystal in the normal mode (i.e. the first mode described above). In the case where no voltage is applied, the fogging liquid crystal does not fog, at this time, the light does not change the propagation direction after passing through the fogging liquid crystal; in the case where a voltage is applied, the fogging liquid crystal fogs, at this time, the light is scattered after passing through the fogging liquid crystal. Figure 6 Figure 7 Exemplarily, the fogging liquid crystal is a liquid crystal of a special material, which is divided into a normal mode and a non-normal mode (i.e. the first mode and the second mode described above), as shown in FIG. 1, which is a fogging schematic diagram of the fogging liquid crystal in the normal mode (i.e. the first mode described above). In the case where no voltage is applied, the fogging liquid crystal does not fog, at this time, the light does not change the propagation direction after passing through the fogging liquid crystal; in the case where a voltage is applied, the fogging liquid crystal fogs, at this time, the light is scattered after passing through the fogging liquid crystal.

[0041] It should be noted that the integrated imaging system based on the multi-layer fogging liquid crystal in the embodiment of the present application uses a time sequence voltage to control each layer of the multi-layer fogging liquid crystal to fog periodically, and only one layer of the fogging liquid crystal fogs at a time.

[0042] Exemplarily, in the case where the focal length of the lens in the lens array is fixed, the distance between any fogging liquid crystal in the multi-layer fogging liquid crystal and the lens is negatively related to the imaging distance. The relationship between the distance between the fogging liquid crystal and the lens , the imaging distance corresponding to the fogging liquid crystal , and the focal length of the lens can be represented by the following formula:

[0043]

[0044] Exemplarily, each layer of the multi-layer fogging liquid crystal is uniformly distributed; and the layers of the multi-layer fogging liquid crystal are filled with a transparent material (such as an acrylic plate) or a gas with uniform density (such as air, nitrogen, etc.). ​

[0045] This application provides an integrated imaging system based on multilayer fogged liquid crystal, used for loading a liquid crystal panel containing an image to be displayed, a lens array, multilayer fogged liquid crystal located between the liquid crystal panel and the lens array, and an imaging control unit. The imaging control unit is used to determine the imaging depth of each part of the image to be displayed. The imaging control unit is also used to determine the area requiring fogging for each layer of the multilayer fogged liquid crystal based on the imaging depth of each part of the image to be displayed and the corresponding imaging depth distribution of the multilayer fogged liquid crystal. The imaging control unit is also used to sequentially control the fogging of each layer of the multilayer fogged liquid crystal in the required fogging area using a timing voltage. Parallel light emitted from the liquid crystal panel is scattered after entering the fogged area of ​​the fogged liquid crystal. The light scattered by the fogged liquid crystal is imaged through the lens array. During imaging, one layer of fogged liquid crystal is controlled to fog at a time. Thus, by mapping the image onto fogged liquid crystals at different locations, a continuous depth three-dimensional effect is obtained, allowing the depth of field of different layers to be effectively connected to obtain a continuous stereoscopic depth, resulting in a large display depth and better imaging effect.

[0046] The integrated imaging method based on multilayer atomized liquid crystal provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0047] like Figure 8 As shown in the embodiment of this application, an integrated imaging method based on multilayer atomized liquid crystal is provided. This method may include the following steps 801 to 803:

[0048] Step 801: Determine the imaging depth of each part in the image to be displayed.

[0049] Step 802: Based on the imaging depth of each part in the image to be displayed and the imaging depth distribution corresponding to the multilayer atomized liquid crystal, determine the area in the multilayer atomized liquid crystal that needs to be atomized.

[0050] Step 803: The areas of each layer of the multilayer atomized liquid crystal that need to be atomized are controlled sequentially by timing voltage.

[0051] In this process, parallel light emitted by the liquid crystal panel is scattered after it is incident on the atomized area of ​​the atomized liquid crystal; the light scattered by the atomized liquid crystal is imaged through a lens array; during image formation, one atomized liquid crystal layer is controlled to atomize at a time.

[0052] Specifically, each atomization of the multilayer atomized liquid crystal comprises multiple liquid crystal blocks, and each liquid crystal block can be atomized independently; step 802 may further include steps 802a1 to 802a3:

[0053] Step 802a1, according to the proportion of the size of the liquid crystal block of each layer of the multi-layered fogging liquid crystal, the image to be displayed is blocked, and a plurality of block images to be displayed are obtained.

[0054] Step 802a2, determining the imaging depth of each block image to be displayed in the plurality of block images to be displayed.

[0055] Step 802a3, based on the imaging depth of each block image to be displayed and the corresponding imaging depth distribution of the multi-layered fogging liquid crystal, the corresponding fogging liquid crystal of each block image to be displayed and the corresponding liquid crystal block in the fogging liquid crystal are determined.

[0056] Specifically, the fogging liquid crystal includes a first mode and a second mode; the step 803 can further include the following step 803a1 or step 803a2:

[0057] Step 803a1, in the case that the fogging liquid crystal is in the first mode, the fogging liquid crystal is controlled to fog by applying a voltage.

[0058] Step 803a2, in the case that the fogging liquid crystal is in the second mode, the fogging liquid crystal is controlled to fog by canceling the voltage applied to the fogging liquid crystal.

[0059] It should be noted that the steps of the integrated imaging method based on the multi-layered fogging liquid crystal provided by the application embodiment have been described in detail in the above-mentioned integrated imaging system based on the multi-layered fogging liquid crystal. In order to avoid repetition, it will not be repeated here.

[0060] Since the light field display system based on integrated imaging in the related art generally has the problems of single display depth and small depth of field. A series of subsequent optimization methods also have the problem of large difficulty in multi-device splicing. Therefore, the integrated imaging system based on the multi-layered fogging liquid crystal provided by the application embodiment can obtain a continuous depth three-dimensional effect by using an algorithm to map a scene to fogging liquid crystals at different positions. The depth of field of different layers can be effectively connected together to obtain continuous stereoscopic depth.

[0061] The embodiment of the present application provides an integrated imaging method based on multi-layer atomized liquid crystal, which is applied to an imaging control unit in an integrated imaging system based on multi-layer atomized liquid crystal. The system further comprises a liquid crystal panel for loading a to-be-displayed image, a lens array, and multi-layer atomized liquid crystal located between the liquid crystal panel and the lens array. The method comprises the following steps: determining the imaging depth of each part in the to-be-displayed image; determining the area of each layer of the multi-layer atomized liquid crystal that needs to be atomized based on the imaging depth of each part in the to-be-displayed image and the corresponding imaging depth distribution of the multi-layer atomized liquid crystal; and atomizing the area of each layer of the multi-layer atomized liquid crystal that needs to be atomized by time sequence voltage.
