Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The technical contents of the present invention will be described in detail by specific embodiments.

The first embodiment:

fig. 1 is a schematic cross-sectional structure diagram of a transparent panel according to a first embodiment of the present invention. As shown in fig. 1, the transparent panel includes a first substrate 10 and a second substrate 20 disposed at an interval, and further includes a light adjusting module 30 disposed between the first substrate 10 and the second substrate 20. The first substrate 10 is provided with a first electrode 11 on a side facing the light modulation module 30, and the second substrate 20 is provided with a second electrode 21 on a side facing the light modulation module 30. Under the action of the electric fields of the first electrode 11 and the second electrode 21, the light adjusting module 30 can deform to adjust the light emitting direction of the light passing through the transparent panel.

In the transparent panel of the embodiment of the invention, under the action of the electric fields of the first electrode 11 and the second electrode 21, the light ray adjusting module 30 can be deformed to adjust the light emitting direction of the light ray passing through the transparent panel, so that the deformation of the light ray adjusting module 30 can be obtained by applying voltage to the first electrode 11 and the second electrode 21, and the light emitting direction of the light ray passing through the transparent panel can meet specific requirements.

It is easily understood that the base material of the first substrate 10 may include glass or a polymer material with high transparency, so that the first substrate 10 is transparent. Similarly, the base material of the second substrate 20 may include glass or a polymer material with high transparency, so that the second substrate 20 is transparent.

In one embodiment, as shown in fig. 1, the light ray adjustment module 30 includes a light guide 33 and a first deformation layer 31. First deformation layer 31 is provided on the side wall of light guide 33. The first electrode 11 includes a first sub-electrode 111 corresponding to the first deformation layer 31, and the second electrode includes a third sub-electrode 211 corresponding to the first deformation layer 31. The first deformation layer 31 deforms under the action of the electric fields of the first sub-electrode 111 and the third sub-electrode 211, so that the light emitting surface of the light guide 33 deflects towards one side, and the light emitting direction of the light passing through the light guide 33 is adjusted.

In another embodiment, as shown in FIG. 1, the light conditioning module 30 further includes a second deformation layer 32. The second deformation layer 32 is provided on the side wall of the light guide 33, and the first deformation layer 31 and the second deformation layer 32 are provided oppositely. The first electrode 11 further includes a second sub-electrode 112, and the second sub-electrode 112 corresponds to the second deformation layer 32. The second electrode 21 further includes a fourth sub-electrode 212, and the fourth sub-electrode 212 corresponds to the second deformation layer 32. The first deformation layer 31 deforms under the action of the electric fields of the first sub-electrode 111 and the third sub-electrode 211, so that the light emitting surface of the light guide body 33 deflects towards one side; the second deformation layer 32 is deformed by the electric field of the second sub-electrode 112 and the fourth sub-electrode 212, so that the light exiting surface of the light guide 33 is deflected toward the other side. That is, the first deformation layer 31 and the second deformation layer 32 can deflect the light emitting surface of the light guide 33 in opposite directions, for example, the first deformation layer 31 deflects the light emitting surface of the light guide 33 toward the left side, and then the second deformation layer 32 deflects the light emitting surface of the light guide 33 toward the right side to adjust the light emitting direction of the light passing through the transparent panel, so as to adjust the light emitting direction of the light passing through the transparent panel.

In one embodiment, the materials of the first and second deformation layers 31, 32 may each comprise an electroactive polymer (EAP). In one embodiment, the material of both the first deformation layer 31 and the second deformation layer 32 comprises polyvinylidene fluoride. Polyvinylidene fluoride has good piezoelectric properties and antistatic properties, and is a preferable material for the deformation layer.

An electroactive polymer material is a polymer material that can be physically deformed by an electric current, voltage, or electric field, and is characterized by the ability to convert electrical energy into mechanical energy. With the continuous deep and development of the research of electroactive polymer materials, the huge application prospect of the electroactive polymer materials is presented to people. The EAP material can be used as human body limbs, artificial organs, endoscope light guide, force-increasing outer skeleton for astronauts and disabled people, robot muscle manufacture, etc. EAP material can also be used to make smaller devices for use in genetic engineering to manipulate cells. Miniaturization of devices and devices can be achieved by using EAP, thereby driving the development of micro-electro-mechanical technology.

Electroactive polymer materials can be classified into two major types, an electronic type and an ionic type, according to the mechanism of deformation generation. In this embodiment, the electroactive polymer material is an electronic electroactive polymer material, and includes an all-organic composite material (AOC), a dielectric elastomer, a piezoelectric polymer, a ferroelectric polymer, an electrostrictive polymer, a liquid crystal elastomer, and the like. Under the action of an electric field, coulomb force induction causes the electronic electroactive polymer material to generate electrostrictive effect and electrostatic, piezoelectric and ferroelectric effects, so that the electroactive polymer material generates induced displacement under the action of a direct current electric field.

In order to make the light guide 33 deformable with the deformation layer, in one embodiment, the material of the light guide 33 includes a transparent polymer material with elasticity, such as transparent silicone or the like. The light guide 33 made of such a material has a good light guiding effect, and light entering the light guide 33 from the first substrate 10 can be emitted from the light emitting surface (the surface facing the second substrate) of the light guide 33. The light guide 33 is made of an elastic transparent polymer material, so that when the first deformation layer deforms, the light guide 33 deforms along with the deformation of the first deformation layer at a side of the light guide 33 close to the first deformation layer due to the material of the light guide 33, and the light emitting surface of the light guide 33 deflects towards one side. Similarly, when the second deformation layer deforms, one side of the light guide 33 near the second deformation layer deforms along with the deformation of the second deformation layer, so that the light emitting surface of the light guide 33 deflects toward the other side. For example, when first deformation layer 31 is shortened in the direction perpendicular to first substrate 10, the side of light guide body 33 close to first deformation layer 31 is also shortened, so that the light exit surface of light guide body 33 is deflected to the left; when the second deformation layer 32 is shortened in the direction perpendicular to the first substrate 10, the side of the light guide 33 close to the second deformation layer 32 is also shortened, so that the light exit surface of the light guide 33 is deflected to the right.

In a specific implementation, the first and second deformation layers 31 and 32 may be film layers coated on the side walls of the light guide 33, so that the adhesion of the first and second deformation layers 31 and 32 to the light guide 33 may be improved, facilitating the deformation of the light guide 33 along with the deformation of the deformation layers.

In the present embodiment, the first deformation layer 31 is deformed in the direction perpendicular to the first substrate under the action of the electric field of the first sub-electrode 111 and the third sub-electrode 211, so that the side of the light guide 33 contacting with the first deformation layer 31 is also deformed, and the light emitting surface of the light guide 33 is further deflected; the second deformation layer 32 is deformed in a direction perpendicular to the first substrate by the electric field of the second sub-electrode 112 and the fourth sub-electrode 212, so that the side of the light guide 33 contacting the second deformation layer 32 is also deformed, and the light emitting surface of the light guide 33 is deflected.

Fig. 2 is a schematic structural diagram of the deformed light ray adjusting module. As shown in fig. 2, the first and second deformation layers 31 and 32 are provided on the left and right side walls of the light guide 33, respectively. A voltage is applied to the first sub-electrode 111 and the third sub-electrode 211, so that an electric field is generated between the first sub-electrode 111 and the third sub-electrode 211, and the first deformation layer 31 is shortened by the electric field, that is, the size of the first deformation layer 31 in the direction perpendicular to the first substrate is shortened. Thus, under the influence of the deformation of first deformation layer 31, the side (left side) of light guide 33 close to first deformation layer 31 shortens as first deformation layer 31 shortens, so that the light exit surface of light guide 33 is deflected toward first deformation layer 31 side. Therefore, when light enters from the first substrate 10 and exits from the light exit surface of the light guide 33, since the light exit surface deflects to the left, the light exiting from the light guide 33 also deflects to the left, and further the light exiting from the second substrate also deflects to the left, thereby realizing adjustment of the light exit direction of the light passing through the transparent panel. In practical implementation, suitable electroactive polymer materials may be selected such that the shortening of the first deformation layer 31 is proportional to the voltage between the first sub-electrode 111 and the third sub-electrode 211, for example, the material of the first deformation layer may include an electrostrictive graft elastomer, and the deformation amount of the material may increase with the increase of the electric field strength. Therefore, the shortening amount of the first deformation layer 31 can be controlled by adjusting the voltage between the first sub-electrode 111 and the third sub-electrode 211, and the deflection angle of the light emitting surface of the light guide body 33 can be further controlled, so as to meet the actual requirement. Of course, the material of the first deformation layer 31 is different, and the deformation direction of the first deformation layer is different, for example, the first deformation layer may also be elongated in the vertical direction under the application of the electric field, so that the light emitting surface of the light guide body is deflected toward the opposite side of the first deformation layer.

FIG. 3 is a schematic diagram of another modified structure of the light adjusting module. In fig. 3, a voltage is applied to the second sub-electrode 112 and the fourth sub-electrode 212, so that an electric field is generated between the second sub-electrode 112 and the fourth sub-electrode 212, and the second deformation layer 32 is shortened by the electric field, that is, the size of the second deformation layer 32 in the direction perpendicular to the first substrate is shortened. Thus, under the influence of the deformation of the second deformation layer 32, the side (right side) of the light guiding body 33 close to the second deformation layer 32 is shortened as the second deformation layer 32 is shortened, so that the light exit surface of the light guiding body 33 is deflected toward the second deformation layer 32 side. Therefore, the light emitted by the second substrate is deflected towards the right side, and the adjustment of the light emitting direction of the light penetrating through the transparent panel is realized. In practical implementation, the electro-active polymer material may be selected such that the amount of shortening of the second deformation layer 32 is proportional to the voltage between the second sub-electrode 112 and the fourth sub-electrode 212, for example, the material of the second deformation layer may include an electrostrictive graft elastomer, and the amount of deformation of the material may increase with the increase of the electric field strength. Therefore, the shortening amount of the second deformation layer 32 can be controlled by adjusting the voltage between the second sub-electrode 112 and the fourth sub-electrode 212, and the deflection angle of the light emitting surface of the light guide 33 can be controlled, so as to meet the actual requirement. Of course, the material of the second deformation layer 32 is different, and the deformation direction of the second deformation layer is different, for example, the second deformation layer may also be elongated in the vertical direction under the application of the electric field, so that the light emitting surface of the light guiding body is deflected towards the opposite side of the second deformation layer.

By controlling the voltage between the first sub-electrode 111 and the third sub-electrode 211 and the voltage between the second sub-electrode 112 and the fourth sub-electrode 212, the deformation amounts of the first deformation layer 31 and the second deformation layer 32 can be controlled, so as to precisely control the deflection direction of the light exit surface of the light guide 33, and further control the light exit direction of the light passing through the light guide 33.

In order to allow the light incident from the first substrate 10 to be incident into the light guide 33 well, the surface of the light ray adjustment module 30 facing the first electrode 11 side is in direct contact with the surface of the first electrode 11, as shown in fig. 1. A first insulating layer 113 is further disposed on a side of the first substrate 10 facing the light modulation module, the first insulating layer 113 is located between the first sub-electrode 111 and the second sub-electrode 112, and a surface (upper surface) of the first insulating layer 113 facing the light modulation module 30 is flush with surfaces of the first sub-electrode 111 and the second sub-electrode 112. Therefore, the light ray adjusting module 30 can be smoothly attached to the surfaces of the first electrode 11 and the first insulating layer 113 through the transparent adhesive tape, so that light rays emitted from the first substrate can directly enter the light ray adjusting module 30 through the first electrode and the first insulating layer, and the influence of air gaps on the light rays is avoided.

In this embodiment, the first electrode 111, the second electrode 112, and the first insulating layer 113 are all made of transparent materials, for example, the first electrode and the second electrode may be made of transparent conductive materials such as indium tin oxide or indium zinc oxide, and the first insulating layer may be made of transparent insulating materials such as silicon oxide, silicon nitride, or silicon oxynitride. It is easy to understand that a second insulating layer located between the third electrode 311 and the fourth electrode 212 may also be disposed on a side of the second substrate facing the light adjustment module, and a lower surface of the second insulating layer is flush with a lower surface of the second electrode.

In one embodiment, as shown in FIG. 1, the light exit surface of light guide 33 is a convex arc surface. The light-emitting surface has a good light converging effect. When the light source incident to the light guide 33 is a point light source, parallel outgoing light can be obtained, and the light transmission uniformity of the transparent panel can be improved.

Fig. 4 is a view taken along the line a-a in fig. 1. As shown in fig. 4, in the present embodiment, the light guiding body 33 is a columnar body, for example, a columnar body in the direction perpendicular to the first substrate 10, and the first and second deformation layers 31 and 32 are provided on the side walls on the opposite sides of the columnar light guiding body 33. In the embodiment shown in fig. 4, the light exit surface of the light guide 33 is spherical, so that when the light source incident on the light guide 33 is a point light source, the light emitted from the light exit surface is a columnar light. In other embodiments, the light guide 33 may also be a polygonal column, such as a quadrangular column, a hexagonal column, or the like.

Fig. 5 is a view B-B in fig. 1. As shown in fig. 5, in the present embodiment, the number of the light ray adjusting modules 30 is multiple, the light ray adjusting modules 30 are arranged in an array between the first substrate 10 and the second substrate 20, and then the first electrodes and the second electrodes are arranged in a corresponding array, and the first electrodes and the second electrodes are both arranged in one-to-one correspondence with the light ray adjusting modules. Like this, through adjusting the electric field that light regulation module 30 corresponds, can be so that the light of partial light regulation module 30 outgoing towards the left side, the light of partial light regulation module 30 outgoing towards the right side, that is to say, can be so that the light that sees through transparent panel has different light-emitting direction.

In order to maintain a certain distance between the first substrate 10 and the second substrate 20, as shown in fig. 1, a sealant frame 40 is disposed between the first substrate 10 and the second substrate 20, and the light ray adjusting module 30 is located inside the sealant frame 40. The sealant frame 40 not only can keep a certain distance between the first substrate 10 and the second substrate 20, but also can protect the light adjusting module 30, thereby preventing the light adjusting module 30 from being polluted and affecting the light adjustability of the transparent panel.

In one embodiment, the transparent panel may further include a control module electrically connected to the first electrode 11 and the second electrode 21, the control module being configured to apply corresponding voltages to the first electrode 11 and the second electrode 21.

FIG. 6 is a schematic top view of a light conditioning module according to another embodiment. In another embodiment, the light guide 33 is a strip-shaped body, and the light emergent surface of the light guide 33 is a convex arc surface. As shown in fig. 6, the first deformation layer 31 and the second deformation layer 32 are respectively provided on the opposite side walls of the strip light guide 33. Correspondingly, the first sub-electrode 111, the second sub-electrode 112, the third sub-electrode 211 and the fourth sub-electrode 212 are also strip-shaped electrodes.

Fig. 7 is a schematic top view of a transparent panel according to another embodiment. As shown in fig. 7, in another embodiment, the number of the light ray adjusting modules is plural, and the plural light ray adjusting modules are sequentially arranged at intervals in a direction perpendicular to the extending direction of the light guide body between the first substrate 10 and the second substrate 20. For example, the light guide extends in a first direction (vertical direction in fig. 7), and the plurality of light ray adjusting modules are sequentially spaced in a second direction (horizontal direction in fig. 7), which is perpendicular to the first direction. The first electrode and the second electrode are arranged in one-to-one correspondence with the light ray adjusting module.

Second embodiment:

FIG. 8 is a schematic top view illustrating a light adjusting module according to a second embodiment of the present invention. Unlike the first embodiment, in the present embodiment, the light ray adjusting module includes a light guide body 33 and a plurality of first deformation layers 31 disposed on the side wall of the light guide body 33, the plurality of first deformation layers 31 are disposed at regular intervals along the circumferential direction of the light guide body 33, the first electrodes include first sub-electrodes disposed in one-to-one correspondence with the plurality of first deformation layers 31, and the second electrodes include third sub-electrodes disposed in one-to-one correspondence with the plurality of first deformation layers 31. Thus, the first deformation layer 31 can be deformed by the electric field between the corresponding first sub-electrode and the corresponding third sub-electrode, so that the light emitting surface of the light guide body is deflected toward one side. Typically, the number of first deformable layers 31 is an even number, such as 4, 6 or 8, etc.

With the structure, the light-emitting surface of the light guide body can be controlled to deflect towards any side within the range of 360 degrees, so that the light-emitting direction of the transparent panel has more selectivity, and more specific requirements can be met.

The third embodiment:

based on the inventive concept of the foregoing embodiments, an embodiment of the present invention provides a autostereoscopic display apparatus. Fig. 9 is a schematic structural diagram of a autostereoscopic display apparatus according to a third embodiment of the invention, and as shown in fig. 9, the autostereoscopic display apparatus includes a display panel 50 and the transparent panel of the foregoing embodiment, and the transparent panel is disposed on a light emitting side of the display panel 50.

When the light guide 33 is a cylindrical body in a direction perpendicular to the first substrate 10, the light adjusting module 30 can correspond to the pixels of the display panel one by one, and thus the light adjusting module 30 can adjust the light emitting direction of the light emitted from the corresponding pixels after passing through the transparent panel. Through the deformation of each light regulation module of accurate control, can make the light-emitting direction of some pixel shoot the people left eye, the light-emitting direction of another part pixel shoots the people right eye to realize the bore hole stereoscopic display.

When the light guide 33 is a strip-shaped body, the light adjusting module 30 can correspond to the pixel rows or the pixel columns of the display panel one by one, so that the light adjusting module 30 can adjust the light emitting direction of the light emitted from the corresponding pixel rows or the pixel columns after passing through the transparent panel. Through the deformation of each light regulation module of accurate control, can make the light-emitting direction of some pixel columns or pixel row shoot to people's left eye, the light-emitting direction of another part pixel columns or pixel row shoots to people's right eye to realize the bore hole stereoscopic display.
