The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Also, the drawings and description of the embodiments are to be regarded as illustrative in nature, and not as restrictive. Like reference numerals refer to like elements throughout the specification. In addition, the thickness of some layers, films, panels, regions, etc. may be exaggerated in the drawings for understanding and ease of description. It will also be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In addition, "on … …" means that an element is positioned on or under another element, but does not essentially mean that it is positioned on the upper side of the other element according to the direction of gravity. For ease of understanding, the figures of the present invention depict one element on top of another.
Additionally, unless explicitly described to the contrary, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.
It should also be noted that references to "and/or" in embodiments of the invention are intended to include any and all combinations of one or more of the associated listed items. Various components are described in embodiments of the present invention with "first", "second", "third", and the like, but these components should not be limited by these terms. These terms are only used to distinguish one component from another. Also, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
While certain embodiments may be practiced differently, the specific process sequence may be performed differently than described. For example, two processes described consecutively may be performed at substantially the same time or in an order reverse to that described.
The principle of stereoscopic display is to utilize the difference between image information seen by the left eye and image information seen by the right eye of a viewer to enable binocular parallax of the viewer to be fused to generate stereoscopic effect. A common stereoscopic display technology is implemented by using 3D glasses to transmit left and right eye images to left and right eyes of a viewer, respectively; the naked eye stereoscopic display technology gets rid of the constraint of 3D glasses, improves the comfort of viewers, and becomes a future development direction and target.
In the existing naked eye stereoscopic display technology, a stereoscopic display device generally includes a control system, a display module and a light modulation module. The switchable light modulation module can even modulate the image light emitted by the display module through the on-off state of the switchable light modulation module under the control of the control system, so that the free switching of the 2D/3D display device is realized. Fig. 1 is a schematic cross-sectional view illustrating a conventional optical modulation module when no voltage is applied, and fig. 2 is a schematic cross-sectional view illustrating a conventional optical modulation module when a voltage is applied. The light modulation module comprises a lens substrate 1, a lens electrode 2, a lens structure 3, a liquid crystal 4, a spacing electrode 5 and a spacing substrate 6 which are sequentially stacked. As shown in fig. 1, when no voltage is applied between the lens electrode 2 and the space electrode 5, the liquid crystal 4 is in a state of lying down; as shown in fig. 2, when a voltage is applied between the lens electrode 2 and the space electrode 5, the liquid crystal 4 is in a standing state. Therefore, the light modulation module can form a light modulator to modulate the image light emitted by the display module, and the free switching of 2D/3D of the display device is realized.
In two existing implementations of stereoscopic display devices: one is to form an air layer between the display module and the light modulation module, and although this scheme can output a stable stereoscopic image, due to the presence of the air layer, the emissivity of the stereoscopic display device is increased, which affects the visual comfort; the other is to make the display module and the light modulation module directly attached to reduce the thickness and reflectivity of the product, but the scheme is not suitable for products with medium and large sizes, because the stereoscopic display device with medium and large sizes has requirements on the viewing distance, and the distance between the display module and the light modulation module is required to be 1-15 mm. In order to solve the above problems, embodiments of the present invention provide a stereoscopic display panel and a stereoscopic display apparatus, which can achieve a narrow frame or even a frame-free design of a product while reducing the thickness and reflectivity of the product.
Hereinafter, the stereoscopic display panel, the stereoscopic display device, and technical effects thereof will be described in detail.
In a possible implementation manner, fig. 3 illustrates a schematic cross-sectional structure of a stereoscopic display panel provided in an embodiment of the present invention. As shown in fig. 3, the stereoscopic display panel includes: the display module assembly 100, the first adhesive layer 200, the spacing structure 300, the second adhesive layer 400, the light modulation module assembly 500 and the appearance structural member 600.
Specifically, the Display module 100 may be any one of a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) Display device, an Organic Light-Emitting Diode (OLED) Display device, electronic paper, a Quantum Dot Light Emitting Diode (QLED) Display device, a micro LED Display device, a micro OLED Display device, a projection module, and other Display devices, which is not particularly limited in the present invention.
The spacer structure 300 is disposed on the light emitting side of the display module 100, and the spacer structure 300 is attached to the display module 100 through the first adhesive layer 200.
Optionally, the material of the first adhesive layer 200 may be transparent optical adhesive, and the transparent optical adhesive is in a liquid state or a solid state. The spacing structure 300 is connected with the appearance structural member 600 by gluing or welding, and the material of the spacing structure 300 is transparent glass.
The light modulation module 500 is disposed on a side of the spacer structure 300 away from the display module 100, and the light modulation module 500 is attached to the spacer structure 300 through the second adhesive layer 400.
Optionally, the material of the second adhesive layer 400 may be transparent optical adhesive, and the transparent optical adhesive is in a liquid state or a solid state. The light modulation module 500 is a lens (e.g., a switchable liquid crystal lenticular lens) or a grating (e.g., a liquid crystal grating), and the material of the light modulation module 500 may be transparent resin or glass, or may be other transparent materials.
The appearance structural member 600 is used for fixing the display module 100, the first adhesive layer 200, the spacing structure 300, the second adhesive layer 400 and the light modulation module 500. Referring to fig. 3, the display module 100, the spacer 300 and the light modulation module 500 are aligned in the center, and the display module 100, the spacer 300 and the light modulation module 500 are equal in size, so the appearance structural member 600 may be a frame for protecting the internal structure and realizing a narrow frame design.
It can be understood that, because the first adhesive layer 200, the spacer structure 300 and the second adhesive layer 400 are arranged between the light modulation module 500 and the display module 100, and a certain distance (i.e. the sum of the thicknesses of the first adhesive layer 200, the spacer structure 300 and the second adhesive layer 400, D1) is provided between the light modulation module 500 and the display module 100, the stereoscopic display panel can output a stable stereoscopic image, ensure that the thickness of a product is as small as possible, reduce the reflectivity, and improve the visual comfort; meanwhile, the stereoscopic display panel may be adapted to various product sizes by adjusting the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400.
Specifically, the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400 is positively correlated with the viewing distance of the stereoscopic display panel. Namely: the larger the viewing distance of the stereoscopic display panel, the larger the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400; the smaller the viewing distance of the stereoscopic display panel, the smaller the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400.
On the basis of the stereoscopic display panel shown in fig. 3, fig. 4 shows a schematic cross-sectional structure diagram of another stereoscopic display panel provided in the embodiment of the invention. As shown in fig. 4, the stereoscopic display panel may further include: the touch module 700 is disposed between the spacer 300 and the first adhesive layer 200, and the touch module 700 can implement a touch function of the stereoscopic display panel.
Accordingly, the sum D2 of the thicknesses of the first adhesive layer 200, the touch module 700, the spacer structure 300, and the second adhesive layer 400 is positively correlated to the viewing distance of the stereoscopic display panel.
On the basis of the stereoscopic display panel shown in fig. 4, fig. 5 shows a schematic cross-sectional structure diagram of another stereoscopic display panel provided by the embodiment of the invention. As shown in fig. 5, the stereoscopic display panel may further include: and the protective layer 800 is disposed on a side of the light modulation module 500 away from the spacer structure 300, and the protective layer 800 is used for protecting the stereoscopic display panel.
In another possible implementation manner, fig. 6 illustrates a schematic cross-sectional structure of another stereoscopic display panel provided in an embodiment of the invention. As shown in fig. 6, the stereoscopic display panel includes: the display module assembly 100, the first adhesive layer 200, the spacing structure 300, the second adhesive layer 400, the light modulation module assembly 500 and the appearance structural member 600.
Specifically, the display module 100 may be any one of a LCD display device, an LED display device, an OLED display device, electronic paper, a QLED display device, a micro LED display device, a micro OLED display device, and a projection module, which is not particularly limited in the present invention.
The spacer structure 300 is disposed on the light emitting side of the display module 100, and the spacer structure 300 is attached to the display module 100 through the first adhesive layer 200.
Optionally, the material of the first adhesive layer 200 may be transparent optical adhesive, and the transparent optical adhesive is in a liquid state or a solid state. The spacing structure 300 is connected with the appearance structural member 600 by gluing or welding, and the material of the spacing structure 300 is transparent glass.
The light modulation module 500 is disposed on a side of the spacer structure 300 away from the display module 100, and the light modulation module 500 is attached to the spacer structure 300 through the second adhesive layer 400.
Optionally, the material of the second adhesive layer 400 may be transparent optical adhesive, and the transparent optical adhesive is in a liquid state or a solid state. The light modulation module 500 is a lens (e.g., a switchable liquid crystal lenticular lens) or a grating (e.g., a liquid crystal grating), and the material of the light modulation module 500 may be transparent resin or glass, or may be other transparent materials.
The appearance structural member 600 is used for fixing the display module 100, the first adhesive layer 200, the spacing structure 300, the second adhesive layer 400 and the light modulation module 500. Referring to fig. 6, the display module 100, the spacer structure 300 and the light modulation module 500 are aligned in the center, the size of the light modulation module 500 is equal to the size of the spacer structure 300, and the size of the spacer structure 300 is larger than the size of the display module 100, therefore, the appearance structure 600 may be a frame body, and the sidewall of the appearance structure 600 has a step-shaped structure, so that the spacer structure 300 is overlapped with the appearance structure 600, and after the spacer structure 300 is glued or welded to the appearance structure 600, the appearance structure 600 may protect the internal structure thereof and achieve a frameless design.
Further, in order to maintain the aesthetic appearance of the stereoscopic display panel, the ink 301 may be printed on the edge of the spacing structure 300 and on a side close to the display module 100 and/or a side close to the light modulation module 500 (in fig. 6, the ink 301 is drawn by way of example on a side close to the display module 100 and a side close to the light modulation module 500), and the ink 301 covers at least a region of the spacing structure 300 beyond the display module 100. That is, the ink 301 covers at least the step-like structure of the side wall of the exterior structural member 600.
Optionally, the visible light transmittance of the ink 301 is less than 5% and the dyne value is greater than 35.
Assuming that the stereoscopic display panel is rectangular, fig. 7 is a schematic top view of an ink provided by an embodiment of the invention. As shown in FIG. 7, the inks U/D/L/R can be as wide; the width of the D is different from the width of other three sides, and thus, an under-screen structure such as a sensor can be arranged in the area of the D.
It can be understood that, because the first adhesive layer 200, the spacer structure 300 and the second adhesive layer 400 are arranged between the light modulation module 500 and the display module 100, and a certain distance (i.e. the sum of the thicknesses of the first adhesive layer 200, the spacer structure 300 and the second adhesive layer 400, D1) is provided between the light modulation module 500 and the display module 100, the stereoscopic display panel can output a stable stereoscopic image, ensure that the thickness of a product is as small as possible, reduce the reflectivity, and improve the visual comfort; meanwhile, the stereoscopic display panel may be adapted to various product sizes by adjusting the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400.
Specifically, the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400 is positively correlated with the viewing distance of the stereoscopic display panel. Namely: the larger the viewing distance of the stereoscopic display panel, the larger the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400; the smaller the viewing distance of the stereoscopic display panel, the smaller the sum D1 of the thicknesses of the first adhesive layer 200, the spacer structure 300, and the second adhesive layer 400.
On the basis of the stereoscopic display panel shown in fig. 6, fig. 8 shows a schematic cross-sectional structure diagram of a stereoscopic display panel provided in an embodiment of the present invention. As shown in fig. 8, the stereoscopic display panel may further include: the touch module 700 is disposed between the spacer 300 and the first adhesive layer 200, and the touch module 700 can implement a touch function of the stereoscopic display panel.
Accordingly, the sum D2 of the thicknesses of the first adhesive layer 200, the touch module 700, the spacer structure 300, and the second adhesive layer 400 is positively correlated to the viewing distance of the stereoscopic display panel.
On the basis of the stereoscopic display panel shown in fig. 8, fig. 9 shows a schematic cross-sectional structure diagram of yet another stereoscopic display panel provided by the embodiment of the invention. As shown in fig. 9, the stereoscopic display panel may further include: and the protective layer 800 is disposed on a side of the light modulation module 500 away from the spacer structure 300, and the protective layer 800 is used for protecting the stereoscopic display panel.
