Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

The first embodiment of the present invention relates to a screen, including a deformation layer and an image layer; wherein, the image layer is used to generate a visible planar image; the deformation layer includes electro-deformation units, and the electro-deformation units are distributed in different regions of the image layer , used to generate deformation in a direction perpendicular to the image layer; the electro-deformation unit is transparent, and the visible plane image generated by the image layer is displayed through the electro-deformation unit.

Specifically, as shown in FIG. 1 , the screen includes a deformation layer 101 and an image layer 102 . Wherein, the image layer 102 is used to produce a visible planar image; the deformation layer 101 includes a single-layer array composed of a plurality of electro-deformation units 103, and each electro-deformation unit 103 in the array is distributed in different regions of the image layer 102, The electro-deformation units 103 are transparent and can deform in a direction perpendicular to the image layer 102 , and the visible planar image generated by the image layer 102 is displayed through each electro-deformation unit 103 .

Since the electro-deformable units 103 in the screen-deformable layer 101 can respectively produce deformations in the direction perpendicular to the image layer 102, the visible planar images generated by the image layer 102 will form different refractions through the electro-deformable units 103 of different heights, It can make the displayed image more three-dimensional, forming the effect of 3D image.

The two ends of each electro-deformation unit 103 in the deformation layer 101 (perpendicular to the direction of the image layer 102) are respectively attached to the transparent film 104 etched with metal lines. Through these metal lines, the electro-deformation units 103 can be made There are different voltage differences. Wherein, one of the two transparent films 104 can overlap with the image layer 102 (directly marked as 102 in the figure), and the other layer is a flexible material that can be deformed within a certain range.

The electro-deformation unit 103 is made of an electro-expandable material, which can be an electro-thermal material, that is, a material that expands when heated, or a piezoelectric material, that is, a material that deforms when a voltage is applied. The electro-deformation unit 103 deforms in a direction perpendicular to the image layer 102 according to the applied voltage difference, and the magnitude of the applied voltage difference is determined by the plane image corresponding to the electro-deformation unit 103, and the plane image is the image layer 102 The resulting image. For example, it can be determined according to the gray scale of the planar image corresponding to the electro-deformation unit 103 , so as to ensure that the degree of deformation of the electro-deformation unit matches the 3D effect required by the image. The specific structure of the electro-deformation unit 103 may be as shown in FIG. 2 , including a conductive working area and a dielectric-filled intersecting area of an electro-expandable material capable of generating deformation.

In addition, since the application direction of the voltage on the electro-deformation unit 103 is perpendicular to the image layer 102, under the action of the voltage, the electro-deformation unit 103 mainly deforms in the direction perpendicular to the image layer 102, and deforms in the direction parallel to the image layer 102. The direction change is small. In order to ensure the display effect of the image, the electro-deformable units 103 in the deformable layer 101 can be closely connected, as shown in FIG. The display is performed under the refraction of , and the degree of deformation of the electro-deformation unit 103 in the direction parallel to the image layer 102 is further limited.

The second embodiment of the present invention also relates to a screen, which is similar to the first embodiment, the difference is that in the first embodiment, the deformable layer includes a single-layer array composed of a plurality of electro-deformation units; and in this embodiment In an embodiment, the array included in the deformable layer is a stacked array, which is obtained by stacking multiple layers of electro-deformation units, as shown in FIG. 4 . Wherein, the two layers of electro-deformation units can be separated by an insulating layer. Due to the limited ductility of the material, a single electro-deformation unit can only produce deformation within a limited range. By superimposing the electro-deformation unit in multiple layers, the deformation range of the deformation layer is larger, which in turn makes the plane image refraction The obtained 3D effect is more obvious, and the stereoscopic effect of the generated 3D image is stronger.

The third embodiment of the present invention relates to a screen comprising a deformation layer and an image layer. Among them, the image layer is used to produce a visible planar image; the deformation layer includes an electro-deformation unit, and the electro-deformation unit is attached to different regions of the image layer; the electro-deformation unit is used to generate deformation in a direction perpendicular to the image layer , the planar image generated by the image layer produces concavo-convex according to the deformation of each electro-deformable unit.

Specifically, as shown in FIG. 5 , the screen includes a deformation layer 501 and an image layer 502 . Wherein, the image layer 502 is used to produce a visible planar image; the deformable layer 501 includes an array composed of a plurality of electro-deformation units 503, and each electro-deformation unit 503 in the array is respectively attached to different regions of the image layer 502 Each electro-deformation unit 503 can generate deformation in a direction perpendicular to the image layer 502 , and the planar image generated by the image layer 502 produces concavo-convex according to the deformation of each electro-deformation unit 503 .

Since the electro-deformation units 503 in the screen deformation layer 501 can respectively produce deformations in the direction perpendicular to the image layer 502, the image layer 502 attached to these electro-deformation units 503 will produce unevenness, thereby creating a more three-dimensional 3D image.

The two ends of each electro-deformation unit 503 in the deformation layer 501 (in the direction perpendicular to the image layer 502) are respectively bonded to the transparent film 504 etched with metal lines. Through these metal lines, the electro-deformation units 503 can be made There are different voltage differences. Wherein, one of the two layers of transparent film 504 can overlap with the image layer 502 (directly marked as 502 in the figure), and the overlapped transparent film 504 and image layer 502 are flexible materials that can be deformed according to the deformation of the electro-deformation unit 503 .

The electro-deformation unit 503 is made of an electro-expandable material, which can be an electro-thermal material, that is, a material that expands when heated, or a piezoelectric material, that is, a material that deforms when a voltage is applied. The electro-deformation unit 503 deforms in a direction perpendicular to the image layer 502 according to the applied voltage difference, and the magnitude of the applied voltage difference is determined by the plane image corresponding to the electro-deformation unit 503, and the plane image is the image layer 502 The resulting image. For example, it can be determined according to the gray scale of the planar image corresponding to the electro-deformation unit 503 , so as to ensure that the degree of deformation of the electro-deformation unit matches the 3D effect required by the image. The structure of the electro-deformation unit 503 may be as shown in FIG. 2 , including a conductive working area and a dielectric-filled intersecting area of an electro-expandable material capable of generating deformation.

In addition, since the direction of applying the voltage on the electro-deformation unit 503 is perpendicular to the image layer 502, under the action of the voltage, the electro-deformation unit 503 mainly deforms in the direction perpendicular to the image layer 502, and deforms in the direction parallel to the image layer 502. The direction change is small. In order to ensure the display effect of the image, the electro-deformable units 503 in the deformable layer 501 can be closely connected, as shown in FIG. The display is performed under the refraction of , and the degree of deformation of the electro-deformation unit 503 in the direction parallel to the image layer 502 is further limited.

The fourth embodiment of the present invention also relates to a screen, which is similar to the third embodiment, the difference is that in the third embodiment, the electro-deformation units in the deformation layer are distributed in the form of a single-layer array; and in the third embodiment In this embodiment, the electrostrain units in the deformable layer are distributed in the form of stacked arrays, that is, multi-layered electrostrain units are stacked, as shown in FIG. 4 . Wherein, the two layers of electro-deformation units can be separated by an insulating layer. Due to the limited ductility of the material, a single electro-deformation unit can only produce deformation within a limited range. By superimposing the electro-deformation unit in multiple layers, the deformation range of the deformation layer is larger, which in turn makes the image layer produce The bumps and convexities are more obvious, and the three-dimensional effect of the 3D image produced is stronger.

The fifth embodiment of the present invention relates to a display system. As shown in FIG. 6 , it includes any one of the screens in Embodiments 1 to 4, and also includes: a voltage difference judging unit, which is used for different plane images generated according to the image layer of the screen. The regions respectively determine the voltage difference; the voltage applying unit adds the voltage difference to each electro-deformation unit in the deformable layer according to the voltage difference determined by the voltage difference judging unit.

Since in a planar image, the distance of an object is usually represented by the depth of the color, the voltage difference can be determined according to the grayscale of different areas of the planar image, so that the degree of deformation produced by the electro-deformation unit is the same as that of the planar image corresponding to the unit. In proportion to the gray scale of the pattern, or, the voltage difference can also be determined according to other data used to represent the distance of the pattern.

The sixth embodiment of the present invention relates to a display method, as shown in FIG. 7 .

In step 701, voltage difference values are respectively determined according to different regions of the planar image generated on the screen.

In step 702, according to the determined voltage difference, the voltage difference is respectively applied to the electro-deformation units in each area of the screen, so that each electro-deformation unit deforms according to the applied voltage difference.

There is a three-dimensional effect.

Since in a planar image, the distance of an object is usually represented by the depth of the color, the voltage difference can be determined according to the grayscale of different areas of the planar image, so that the degree of deformation produced by the electro-deformation unit is the same as that of the planar image corresponding to the unit. The grayscale is proportional to ensure that the displayed 3D images are more realistic.

The sixth embodiment of the present invention relates to a display method, as shown in FIG. 8 .

In step 801, voltage difference values are respectively determined according to different regions of the planar image generated on the screen.

In step 802, according to the determined voltage difference, the voltage difference is respectively applied to the electro-deformation units in each area of the screen, so that each electro-deformation unit deforms according to the applied voltage difference.

In step 803, the screen generates concavities and convexities according to the deformation of each electro-deformation unit, and the image is displayed through the concavo-convex screen.

Since the electro-deformation units in the screen-deformation layer can respectively generate deformations in the direction perpendicular to the image layer, the image layer attached to these electro-deformation units is concave-convex, thereby generating a more three-dimensional 3D image.

Since in a planar image, the distance of an object is usually represented by the depth of the color, the voltage difference can be determined according to the grayscale of different areas of the planar image, so that the degree of deformation produced by the electro-deformation unit is the same as that of the planar image corresponding to the unit. The grayscale is proportional to ensure that the displayed 3D images are more realistic.

To sum up, in the embodiment of the present invention, since the electro-deformation units in the screen deformation layer can respectively generate deformation in the direction perpendicular to the image layer, the visible plane image generated by the image layer can be transmitted through different heights of the electro-deformation unit.

This ensures that the degree of deformation of the electro-deformation unit matches the desired 3D effect of the image.

The array composed of multiple electro-deformation units is a single-layer array; or, it is a laminated array in which multiple layers are stacked. Due to the limited ductility of the material, the deformation produced by a single electro-deformation unit is limited. By superimposing multiple layers, the deformation range of the deformation layer is larger, the effect is more obvious, and the three-dimensional effect of the generated 3D image is better. strong.
