Regardless of the stereoscopic display technology, how to realize the real three-dimensional effect becomes a technical problem which needs to be solved urgently.
In view of this, embodiments of the present invention provide a display device and a display method, which are used to implement stereoscopic display of the display device.
Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention, where the display device includes:
the display module comprises a driving component 1, a display module 2 and a transparent software 3 positioned on one side of a light-emitting surface of the display module 2, wherein when the display module 2 displays a video, the driving component 1 is used for driving the transparent software 3 to generate corresponding deformation corresponding to the position of a specific image according to the information of the specific image in the video.
The transparent soft body 3 can be a film structure formed by a transparent deformable material, the material composing the transparent soft body 3 comprises at least one of Polydimethylsiloxane (PDMS), polystyrene sulfonate (PEDOT: PSS), polyethylene terephthalate (PET), AgNW/CN, liquid crystal elastomer and hydrogel, wherein the hydrogel comprises at least one of Polyacrylamide (PAM) hydrogel and 2-methacryloyloxyethyl phosphorylcholine copolymer hydrogel. Of course, the material for preparing the transparent soft body 3 can also be selected according to the practical application, and is not limited herein. After the transparent soft body 3 of the corresponding material is prepared, one or more external conditions such as electricity, magnetism, sound, light, heat, etc. can stimulate the transparent soft body 3 of the corresponding material, and accordingly, the driving part 1 can drive the transparent soft body 3 to deform, thereby realizing the deformation control of the driving part 1 on the transparent soft body 3.
The transparent soft body 3 is located on the light-emitting surface side of the display module 2, the transparent soft body 3 may be a structure independent from the display module 2, and accordingly, the transparent soft body 3 may be attached to the light-emitting surface of the display module 2 by an optical Adhesive (OCA), for example. The transparent soft body 3 may also be integrated on the display module 2, for example, if the display module 2 is a liquid crystal display module, the display module 2 includes a display substrate, an opposite substrate and a liquid crystal layer located between the display substrate and the opposite substrate, and the transparent soft body 3 may be integrated on a light emitting surface side of the display substrate. In addition, the display module 2 may also be an Organic Light-Emitting semiconductor (OLED), and the transparent soft body 3 may be integrated on a side of the package layer of the OLED away from the Light-Emitting surface thereof, and of course, a person skilled in the art may design the display module 2 according to actual needs, and accordingly, specific positions of the transparent soft body 3 are set, which is not limited herein.
Because the transparent software 3 is the transparent structure, can not influence display module assembly 2's display effect. In addition, when the display module 2 displays a video, the driving component 1 can drive the transparent software 3 to generate a corresponding deformation corresponding to the position of the specific image according to the information of the specific image in the video, where the specific image may be a preset image, such as a hand image, a foot image, a knife, a rod, and the like, the same frame of image may include information of a plurality of specific images, and the driving component 1 can generate a corresponding deformation according to the information of the specific image, that is, combine the information of the specific image in the video with the deformation of the transparent software, thereby implementing the interaction between the transparent software 3 and the specific image in the video. The position of the specific image may be one or more, and the position of the transparent soft body 3 corresponding to the specific image may be deformed, for example, a surface of the transparent soft body 3 away from the light-emitting surface of the display module 2 may form a convex or concave structure, and a plurality of convex or concave structures may be visually perceived by a user, or even tactilely perceived, so that the specific image in the video and the deformation of the transparent soft body 3 at the corresponding position are combined together, thereby achieving a stereoscopic display effect of the display device in the process of displaying the video.
In the embodiment of the present invention, the corresponding deformation includes a convex deformation of the transparent soft body 3 along the light emitting direction of the display module 2 and in a direction away from the light emitting surface of the display module 2, or a concave deformation of the transparent soft body 3 along a direction opposite to the light emitting direction of the display module 2 and away from the light emitting surface of the display module 2.
With reference to fig. 2, the driving component 1 may drive the transparent soft body 3 to generate corresponding deformation corresponding to the position of the specific image, a direction indicated by an arrow X in fig. 2 is a light emitting direction of the display module, a plane where a dotted line Y is located is a surface of the transparent soft body 3 that is away from the light emitting surface of the display module 2 before the transparent soft body is deformed, the driving component 1 may cause the transparent soft body 3 to be convexly deformed along the light emitting direction of the display module 2 and the direction away from the light emitting surface of the display module 2, and accordingly, the surface of the transparent soft body 3 that is away from the light emitting surface of the display module 2 may be deformed into a convex structure as shown in a in fig. 2, and at this time, the corresponding specific image may exhibit a visual effect with a convex sense. In addition, the driving component 1 can also make the transparent soft body 3 deform concavely along the direction opposite to the light emitting direction of the display module 2 and away from the light emitting surface of the display module 2, and accordingly, the surface of the transparent soft body 3 away from the light emitting surface of the display module 2 can change into a concave structure, which is shown as B in fig. 2. In the specific implementation process, in the same video, the transparent soft bodies 3 at the corresponding positions of different specific images can be deformed to different degrees at the same time, and the transparent soft bodies 3 at the corresponding positions of the same specific image at different times can be deformed to different degrees, so that the effect of stereoscopic display is realized in the process of displaying the video.
It should be noted that the convex structure presented in the same region of the transparent soft body 3 may be an effect brought by the deformation of a plurality of protrusions in the region, and the concave structure presented in the same region of the transparent soft body 3 may be an effect brought by the deformation of a plurality of recesses in the region. In the same frame of image in the video, there may be one or more raised structures and also one or more recessed structures, and of course, the deformation of the transparent software at different positions may be controlled according to actual needs, which is not described in detail herein.
In the embodiment of the present invention, the following implementation manners of the driving component 1 can be adopted to drive the transparent soft body 3 to deform according to different specific materials of the transparent soft body 3, but not limited to the following cases.
First implementation
The driving member 1 in the first implementation manner is a thermal actuator, the transparent soft body 3 is a liquid crystal elastic body 31, and the thermal actuator is configured to control the liquid crystal mesogens in the liquid crystal elastic body 31 to mutually transition between a nematic phase and an isotropic phase so as to deform the liquid crystal elastic body 31 while the temperature of the liquid crystal elastic body 31 changes according to the information of the specific image in the video.
The transparent soft body 3 is a liquid crystal elastomer, correspondingly, the driving component 1 is a thermal driver, and the liquid crystal in the liquid crystal elastomer 31 can be rearranged along with the increase of the temperature, so that the transparent soft body has unique performance. Accordingly, the thermal driver is configured to control liquid crystal mesogens in the liquid crystal elastic body 31 to mutually transition between a nematic phase and an isotropic phase while the temperature of the liquid crystal elastic body 31 is changed according to the information of the specific image in the video, so as to cause the liquid crystal elastic body 31 to deform. When the temperature changes, the mesogens of the liquid crystal in the liquid crystal elastic body 31 can be mutually converted between the nematic phase and the isotropic phase, so that the thermal driver can drive the liquid crystal elastic body 31 to generate large deformation in the driving process, and the effect of three-dimensional display is improved.
As a specific example, a polymer brush orientation method may be adopted to vertically orient liquid crystal molecules, and ultraviolet in-situ polymerization is used to construct a gradient cross-linked vertical orientation liquid crystal elastomer, and a film corresponding to the constructed liquid crystal elastomer 31 may undergo reversible and macroscopic bending deformation in the process of temperature increase and decrease, where the deformation is caused by the difference in elastic modulus of the upper and lower surfaces of the film. With reference to the deformation schematic diagram shown in fig. 3, in the temperature rising process, the film corresponding to the liquid crystal elastic body 31 can be bent along the long axis direction of the liquid crystal meson, in the temperature lowering process, the film corresponding to the liquid crystal elastic body 31 can be restored to the undeformed extended state from the bent state, and through the control of temperature rise and drop, the conversion of the liquid crystal elastic body 31 between the bent state and the extended state is realized, thereby ensuring the display effect of the display device.
Second implementation
In a second implementation manner, the driving component 1 is a thermal driver, the transparent soft body 3 includes a first transparent polymer film layer and a second transparent polymer film layer which sequentially depart from the light-emitting surface of the display module 2, a difference between a thermal expansion coefficient of the first transparent polymer film layer and a thermal expansion coefficient of the second transparent polymer film layer is greater than a preset value, and the thermal driver is configured to drive the transparent soft body 3 to deform while the temperature of the transparent soft body 3 changes according to the information of the specific image in the video.
The transparent soft body 3 is a double-layer film structure including the first transparent polymer film layer and the second transparent polymer film layer, and accordingly, the driving member 1 is a thermal actuator, and the thermal actuator may be disposed between the two film layers. Since the difference between the thermal expansion coefficient of the first transparent polymer film layer and the thermal expansion coefficient of the second transparent polymer film layer is greater than a preset value, the preset value is a preset value, that is, the two film layers have a larger thermal expansion coefficient difference, in this way, the thermal driver can drive the transparent soft body 3 to deform to a larger extent, thereby ensuring the stereoscopic display effect of the display device.
As a specific example, the first transparent polymer film layer may be an isotropic polymer film, the second transparent polymer film layer may be an anisotropic polymer film, the anisotropic polymer film may be Low Density Polyethylene (LDPE), and a heater using a silver nanowire (AgNwS) percolation network may be disposed between the two films, so as to obtain thermal driving of the anisotropic polymer film in a machine direction, so as to drive the transparent soft body 3 to deform to a greater extent, thereby ensuring a stereoscopic display effect of the display device.
Third implementation
The driving member 1 in the third implementation manner is an electric driver, the transparent soft body 3 includes at least one of a dielectric elastomer, a hydrogel, polydimethylsiloxane and polystyrene sulfonate, and the electric driver is configured to apply a voltage signal to the transparent soft body 3 according to the information of the specific image in the video to drive the transparent soft body 3 to deform.
The transparent soft body 3 may include at least one of a dielectric elastomer, a hydrogel, Polydimethylsiloxane (PDMS), and polystyrene sulfonate (PEDOT: PSS), and accordingly, the driving component 1 is an electric driver, and can drive the transparent soft body 3 to deform through a high-voltage driven strong electric field, and under the action of the strong electric field, a fast driving speed can be realized, and a large strain force can be generated, so that the deformation performance of the transparent soft body 3 is ensured, and the stereoscopic display effect of the display device is ensured.
For a specific example, if the transparent soft body 3 is a gel, in combination with the deformation diagram shown in fig. 4, the volume of the gel 32 can be changed by the electric driver to drive electrically, thereby realizing the deformation control of the transparent soft body 3. When not powered, the volume of the gel 32 can be restored to the undeformed stretched state, thus achieving the deformation control of the transparent soft body 3.
In the case where the drive member 1 is an electric driver, the electrode arrangement for the energization driving in the electric driver may be, but is not limited to, the following two cases.
First case
The first condition is that the electric driver comprises a plurality of independent first transparent electrodes 11 and a plurality of independent second transparent electrodes which are arranged at two sides of the transparent soft body 3 along the light emitting direction of the display module 2, and the electric driver is used for loading the voltage signal to the transparent soft body 3 through the first transparent electrodes 11 and the second transparent electrodes to drive the transparent soft body 3 to generate deformation.
The electric driver includes a plurality of independent first transparent electrodes 11 and a plurality of independent second transparent electrodes disposed on two sides of the transparent soft body 3 along the light emitting direction of the display module 2, and the specific number of the first transparent electrodes 11 and the specific number of the second transparent electrodes may be set according to practical application conditions, which is not limited herein. Each first transparent electrode 11 and each second transparent electrode can be evenly distributed on the light-emitting surface of the display module 2, and accordingly, the deformation of the transparent software 3 at the position of each first transparent electrode 11 can be controlled, so that the deformation control of the transparent software 3 at different regional positions of the display module 2 can be realized, and the control of the three-dimensional display of the local regional position of the display module 2 is further ensured. In addition, the distribution of the first transparent electrode 11 and the second transparent electrode may be set according to the distribution of the area in the display device that needs to control the stereoscopic display, for example, the first transparent electrode 11 and the second transparent electrode are only distributed in the area of the lower right corner 100 × 100 of the display module 2, so as to implement the stereoscopic display control of the corresponding area, and of course, the first transparent electrode 11 and the second transparent electrode may also be distributed according to the actual need, which is not described in detail herein.
Each of the first transparent electrodes 11 may be a block electrode, and the shape of the electrode may be a diamond shape or a rectangular shape, and correspondingly, each of the second transparent electrodes may also be a block electrode, and the shape of the electrode may also be a diamond shape or a rectangular shape. The voltage signal can be applied to the corresponding electrode through the lead wire coupled with each electrode, so as to control the transparent soft body 3 at the corresponding position to generate deformation. Fig. 5 is a schematic diagram of one distribution of the first transparent electrodes 11. Of course, the distribution of the first transparent electrodes 11 may also be set according to actual needs, and is not limited herein.
Second case
The second case is that the electric driver comprises a plurality of independent third transparent electrodes 12 arranged between the transparent soft body 3 and the display module 2, and the electric driver is used for loading the voltage signal to the transparent soft body 3 through the third transparent electrodes 12 to drive the transparent soft body 3 to generate deformation.
The electric driver comprises a plurality of independent third transparent electrodes 12 arranged between the transparent soft body 3 and the display module 2, each third transparent electrode 12 can be prepared in the same layer, and the specific number of the third transparent electrodes 12 can be set according to the actual deformation requirement, which is not limited herein. Each third transparent electrode 12 may be uniformly distributed on the light emitting surface of the display module 2, so as to ensure the deformation uniformity of each region of the display module 2. Of course, the distribution of the third transparent electrodes 12 may also be set according to the distribution of the regions of the display device that need to control stereoscopic display. For example, the third transparent electrodes 12 are distributed only in the region of the center 50 × 50 of the display module 2, so as to implement the stereoscopic display control of the corresponding region, and of course, the third transparent electrodes 12 may also be distributed according to actual needs, which is not described in detail herein.
Each of the third transparent electrodes 12 may be an interdigital electrode as shown in fig. 6, and a voltage signal may be applied to the corresponding electrode through a lead wire coupled to each interdigital electrode, so as to control the transparent soft body 3 at the corresponding position to deform.
It should be noted that, different voltage signals are applied to the transparent soft bodies 3 at the same position, so that different degrees of deformation can be generated, the voltage signals are respectively applied to the transparent soft bodies 3 at different positions, and the surfaces of the transparent soft bodies 3 departing from the light-emitting surface of the display module 2 can form a plurality of deformed structures, so that the plurality of deformed structures can form a three-dimensional sensing surface which can be sensed by a user, thereby ensuring the three-dimensional display effect of the display device. The material of the transparent electrode mentioned above includes at least one of Indium Tin Oxide (ITO), ion-conductive hydrogel, graphene, Carbon Nanotubes (CNTs), and metal nanowires, and the transparent electrode can be prepared according to practical applications, which is not limited herein.
Fourth mode of implementation
In a fourth implementation manner, the driving component 1 is an optical driver, the transparent soft body 3 is a single-domain liquid crystal elastomer film, and the optical driver is configured to drive the transparent soft body 3 to deform while ultraviolet light irradiates the single-domain liquid crystal elastomer film 33 according to information of the specific image in the video.
The driving component 1 is an optical driver, the transparent soft body 3 is a single-domain liquid crystal elastomer film 33, that is, the deformation control of the transparent soft body 3 is realized by the optical driver, the transparent soft body 3 can be a single-domain liquid crystal elastomer LCE-M film of azobenzene liquid crystal cells, and in combination with the deformation schematic diagram shown in fig. 7, under the irradiation of 365nm ultraviolet light, the optical driver can drive the transparent soft body 3 at the corresponding position to bend and deform towards light, and under the irradiation of 450nm visible light, the optical driver can drive the transparent soft body 3 at the corresponding position to change from the bent state to the undeformed extended state. Therefore, the deformation control of the transparent soft body 3 at the corresponding position can be realized through the optical driver, so that the three-dimensional display effect of the display device is ensured.
Besides the four driving members 1 mentioned above, the driving member 1 can be a pneumatic driver, which can apply an external compressed air source through a valve system to drive the transparent soft body 3 to deform under the condition of high output force, and furthermore, the transparent soft body 3 can be restored to the stretching state under the condition of no additional input energy, so that the using performance of the display device can be improved while the stereoscopic display is ensured.
The driving part 1 can also be a hydraulic driver which comprises a transparent and firm hydrogel shell and a hydraulic chamber consisting of water, and the transparent soft body 3 can be driven to deform by applying certain pressure through the water.
The driving part 1 can also be a driver made of composite material, which does not need electric power to act on the transparent soft body 3, and can control the transparent soft body 3 to deform by using external environmental stimuli such as humidity, pH value and temperature. For example, the composite material may be a Shape Memory Polymer (SMP) that can be configured to change shape at a particular temperature, and the temperature can be controlled to cause a corresponding change in shape. Of course, besides the above-mentioned driving component 1, other forms of driving components 1 can be used to drive the transparent soft body 3 to deform according to the actual application requirement, and will not be described in detail herein.
Based on the same inventive concept, as shown in fig. 8, an embodiment of the present invention further provides a method flowchart of a display method of the display apparatus as described above, where the specific structure of the display apparatus refers to the description of the foregoing part, and is not described in detail here, and the display method includes:

In the specific implementation process, the specific implementation process from step S101 to step S103 is as follows:
firstly, information of a specific image of each image to be displayed in the video to be displayed is determined, wherein the video to be displayed may include a plurality of frames of images to be displayed which are sequentially arranged, the video to be displayed may be decomposed into a plurality of frames of images to be displayed, and information of the specific image is determined from each frame of image to be displayed, for example, the specific image is a fist of a user, and image information of the fist of the user may be determined from the plurality of frames of images to be displayed. Then, the position of the transparent software 3 corresponding to the specific image is determined. Then, the transparent soft body 3 at the position is driven to generate corresponding deformation through the driving part 1.
It should be noted that after the position of the transparent software 3 corresponding to the specific image is determined, a software deformation array signal may be set for the frame image that needs to be deformed, and accordingly, the video playing speed is adjusted, and in combination with the response time of the software deformation and the playing speed of each frame image, the software deformation position and the corresponding image content are matched in time, and then the driving component 1 drives the transparent software 3 at the position to generate corresponding deformation, so that in the process of displaying the video on the display device, the user may feel the screen deformation, thereby realizing the effect of stereoscopic display in the true sense and improving the user experience.

In the specific implementation process, the specific implementation process from step S201 to step S202 is as follows:
after the position of the transparent software 3 corresponding to the specific image is determined, in the process of displaying the video, if a touch operation of a user for the position of the specific image is detected, wherein the touch operation can be a single-click operation, a double-click operation, a sliding operation and the like, the transparent software 3 at the position of the specific image is driven to generate corresponding deformation through the driving part 1 in response to the touch operation. When a user touches the position of the specific image, the driving part 1 can be triggered to drive the transparent software 3 at the corresponding position to generate corresponding deformation, so that the interaction effect of the user and the current video is improved through the deformation, and the use experience of the user is further improved.
For example, when a user can play an electronic game through the display device, once the user touches the hand of a character in the game in the process of displaying a game interface through the display device, the transparent software 3 at the position where the user is located generates corresponding deformation, and the user can sense the hand action of the character, so that the real experience of the user in the game process is enhanced.
