In addition, if a detailed description of the known art is not necessary for illustrating the features of the present application, it is omitted. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

It will be understood by those within the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In the lenticular-based 3D display technology, the size of the lenticular lenses is generally substantially the same as the size of the corresponding pixel groups. The designed visual angle is limited by the cylindrical lens processing technology and the pixel size of the 2D display screen, so that super-multi-viewpoint and super-large visual area cannot be realized, and the requirement for watching by multiple people cannot be met. The advantages of convenient and comfortable watching and wide application range cannot be embodied in market competition. Therefore, the improvement of the naked eye 3D visual area range is an important research direction of the current naked eye 3D technology.

The application provides a bore hole 3D display module, a driving method thereof and a display device, which aim at solving the technical problems in the prior art.

The embodiment of the application provides a naked eye 3D display module, as shown in fig. 1 and fig. 2, the naked eye 3D display module comprises a display screen 1 and a dimming structure 2 arranged on a light emitting surface of the display screen 1.

The display panel 1 includes a plurality of pixel groups 11, each pixel group 11 including x effective pixels 111, x being an integer greater than or equal to 2; the light control structure 2 includes a plurality of lens groups 21, each lens group 21 corresponds to one pixel group 11, each lens group 21 includes a plurality of lenses 211, and only one lens 211 in each lens group 21 is in a transmissive state to pass display light at the same time in the 3D display process.

Specifically, the effective pixels 111 mean that emitted display light can be refracted by any lens in the lens group, and the larger the number of effective pixels 111 in the pixel group 11, the more the corresponding viewpoint liquid crystal.

Specifically, as shown in fig. 2 and fig. 3, taking the lens group 21 including 3 lenses 211 as an example, when the first lens 211/1 is turned on at time sequence 1, the display light emitted by the pixel group 11 can be seen in the viewing zone 1 through the polarization effect of the first lens 211/1, and the image formed by all the pixel groups 11 in the display screen 1 at time sequence 1 is view 1; when the second lens 211/2 is turned on at the time sequence 2, the display light emitted by the pixel group 11 can be seen at the viewing zone 2 through the polarization effect of the second lens 211/2, and the image formed by all the pixel groups 11 at the time sequence 2 in the display screen 1 is the view 2; when the third lens 211/3 is turned on at the time sequence 3, the display light emitted by the pixel group 11 can be seen in the viewing zone 3 through the polarization effect of the third lens 211/3, and the image formed by all the pixel groups 11 in the display screen 1 at the time sequence 3 is the view 3. The splicing of the view 1 to the view 3 is the full view, and the visual area range of the full view is wider.

In the naked eye 3D display module provided by this embodiment, each lens group 21 in the dimming structure 2 includes a plurality of lenses 211, and each lens group 21 corresponds to one pixel group 11, so as to increase the number of effective pixels in each pixel group 11, thereby increasing viewpoints and expanding a viewing area, compared with a case where one lens corresponds to a pixel group 11 in the prior art; meanwhile, the opening sequence of the lenses 211 in each lens group 21 is controlled, only one lens 211 in each lens group 21 is in an open state at the same time in the 3D display process, and other lenses 211 are in a non-light-transmitting state, so that the problem of image crosstalk displayed in adjacent visual areas can be avoided, and the display effect is improved.

Optionally, with continuing reference to fig. 1, the naked-eye 3D display module provided in this embodiment further includes a spacer layer 3, and the spacer layer 3 is located between the dimming structure 2 and the display screen 1. Specifically, the spacer layer 3 is respectively bonded with the dimming structure 2 and the display screen 1, and the spacer layer 3 has good light transmission, on the basis, the material of the spacer layer 3 comprises optical cement, and in order to meet the requirement of a large viewing angle, the thickness of the spacer layer 3 has a certain requirement, so that the spacer layer 3 further comprises spacer glass besides the optical cement, and the spacer glass is respectively bonded with the display screen 1 and the dimming structure 2 through the optical cement. The thickness of the spacer layer 3 is determined according to the focal length and defocus of the lens 211.

Specifically, in an actual design, a theoretical lens focal length is calculated according to a 3D imaging requirement, the theoretical lens 211 focal length only considers light emitted from a center point of the lens 211 during calculation, the focal length of the lens 211 is related to a total thickness of the spacer layer 3 and a ratio of refractive indexes of the film layers in the spacer layer 3, for example, under a condition that the refractive index is determined, the larger the total thickness of the spacer layer 3 is, the larger the focal length of the lens 211 is, and under a condition that the total thickness of the spacer layer 3 is, the larger the refractive index is, the larger the focal length of the lens 211 is.

However, in practical use, each lens 211 in the lens group 21 needs to correspond to one pixel group 11, and as the position of the effective pixel 111 in the pixel group 11 changes, the distance of the effective pixel 111 relative to the lens 211 changes, so that defocus in different degrees is generated. Therefore, in order to balance the defocus of the pixel group, the focal length of the lens 211 is usually optimized in design, so that a certain defocus exists in the effective pixel 111 located at the center of the pixel group 11, and the effective pixels 111 at the opposite edges in the pixel group 11 are at the focal length, so that the defocus of the effective pixel 111 at the edge most in the pixel group 11 is improved, thereby achieving the optimization of the overall imaging effect.

In an alternative embodiment, the dimming structure 2 comprises a first liquid crystal cell 2a, the first liquid crystal cell 2a being configured to form a lens 211 passing display light in a selected area under control of a driving signal at the same time during the 3D display.

Specifically, the first liquid crystal cell 2a includes a first polarizer 204a, a first electrode, a first liquid crystal layer 202a, a second electrode, and a second polarizer 205a sequentially arranged on the light emitting surface of the display screen 1; the polarization angles of the first polarizer 204a and the second polarizer 205a are perpendicular to each other; the first electrode layer 201a includes a plurality of first sub-electrodes 2011a, and during the 3D display process, the second electrode layer 203a is maintained at a common voltage, and each of the first sub-electrodes 2011a is maintained at a corresponding driving voltage according to a driving signal, so that liquid crystal molecules in a selected region of the first liquid crystal layer 202a are deflected to form a lens 211 for passing display light. For example, the first sub-electrodes 2011a in a specific region have a positive voltage, the first sub-electrodes 2011a in the remaining regions have a negative voltage, and the potentials of the first sub-electrodes 2011a in the specific region are different, that is, the potentials of the first sub-electrodes 2011a in the specific region are gradually decreased in a direction in which the center point of the specific region points to the surroundings, so as to control the deflection angles of the liquid crystal molecules at different positions in the specific region, thereby forming the light effect of the lens 211.

Specifically, the first liquid crystal cell 2a in this embodiment is an IPS liquid crystal single-layer cell structure, and the IPS mode is in a normally black state under the non-energized condition, so that it can be ensured that light cannot pass through at the position of the lens 211 that is not opened because the polarization directions of the first polarizer and the second polarizer are orthogonal, that is, light can only pass through a selected region, and thus, an effect of opening only one lens 211 in each lens group 21 is achieved. Meanwhile, since the IPS mode can realize a higher refresh rate in the liquid crystal display, it can also be ensured that the change of the light transmission state between the adjacent lenses 211 is not easily perceived by human eyes, so as to ensure the continuity of the full view.

In another alternative embodiment, as shown in fig. 5, the dimming structure 2 comprises a second liquid crystal cell and an adjustable light transmission layer; the second liquid crystal cell is configured to form a plurality of lens groups 21 under the control of the driving signal, the lens groups 21 including a plurality of lenses 211, each lens 211 in each lens group 21 being in an open state during 3D display; the adjustable light-transmitting layer 206b comprises a plurality of adjustable regions 10, an orthographic projection of each adjustable region 10 on the display screen 1 covers an orthographic projection of the lens 211 on the display screen 1, and each adjustable region 10 is in a light-transmitting state or a light-shielding state under the control of the control signal.

Specifically, as shown in fig. 5, the second liquid crystal cell includes a third electrode layer 201b, a fourth electrode layer 203b, and a second liquid crystal layer 202b located between the third electrode layer 201b and the fourth electrode layer 203b, wherein the third electrode layer 201b includes a plurality of third sub-electrodes 2011b, and during 3D display, the fourth electrode layer 203b is maintained at a common voltage, and each of the third sub-electrodes 2011b is maintained at a corresponding driving voltage according to a driving signal, so as to form a plurality of lenses 211.

In yet another alternative embodiment, as shown in fig. 6, the light modulating structure 2 includes a plurality of dielectric lens groups and an adjustable light transmitting layer 206c; the dielectric lens group includes a plurality of dielectric lenses 211c; the adjustable light-transmitting layer 206c comprises a plurality of adjustable regions 10, each adjustable region 10 is an orthographic projection on the display screen 1 and covers an orthographic projection of the dielectric lens 211c on the display screen 1, and each adjustable region 10 is in a light-transmitting state or a light-shielding state under the control of the control signal.

Specifically, in this embodiment, the lens group is the dielectric lens group 21c, and the lens is the dielectric lens 211c, and it is not necessary to drive the dielectric lens 211c, that is, it is possible to drive whether each adjustable region 10 of the adjustable light-transmitting layer is in the light-transmitting state to realize whether the dielectric lens 211c is turned on.

The adjustable light-transmitting layer can be realized by using liquid crystal technology or by using electrochromic materials, which will be described in detail below.

Specifically, as shown in fig. 7, the tunable light-transmitting layer includes a fifth electrode layer 2061, a sixth electrode layer 2063, and a third liquid crystal layer 2062 located between the fifth electrode layer 2061 and the sixth electrode layer 2063, wherein the fifth electrode layer 2061 includes a plurality of fifth sub-electrodes 20611, and each of the fifth sub-electrodes 20611 corresponds to one of the tunable regions 10 in the above-described embodiment. When the lens 211 (the liquid crystal lens 211 or the dielectric lens 211) corresponding to a certain tunable region 10 needs to be turned on at the current moment, the fifth sub-electrode 20611 corresponding to the tunable region 10 is controlled to be at the on potential.

Specifically, as shown in fig. 8, the tunable light-transmitting layer includes a seventh electrode layer 2064, an eighth electrode layer 2066, and an electrochromic material layer 2065 located between the seventh electrode layer 2064 and the eighth electrode layer 2066, wherein the seventh electrode layer 2064 includes a plurality of seventh sub-electrodes 20641, and each of the seventh sub-electrodes 20641 corresponds to one of the tunable regions 10 in the above-described embodiment. The electrochromic material layer 2065 is in a light transmitting state or a light blocking state under the action of the electric field, so that when the lens 211 (the liquid crystal lens 211 or the dielectric lens 211) corresponding to a certain tunable region 10 needs to be turned on at the present moment, the seventh sub-electrode 20641 corresponding to the tunable region 10 is controlled to be at the turn-on potential, and the electrochromic material layer 2065 of the tunable region 10 is controlled to be in the light transmitting state.
