[0002] With the development of display technology, large-sized displays are now installed on large devices such as mobile phones, tablets, laptops and televisions, making it easier for people to view the content displayed on the screen.

[0003] In related technologies, larger electronic devices are typically equipped with hardware that can accommodate more computing resources, enabling the computational rendering of glasses-free 3D images. However, smaller electronic devices, such as electronic watches and e-cigarettes, have limited hardware resources due to their small size, such as smaller batteries and weaker processors. These devices cannot perform the computational rendering of glasses-free 3D images, thus failing to display them. Utility Model Content

A preset distance is set between each pair of adjacent parallax gratings. The display area between each pair of gratings is used to display sub-images corresponding to multiple naked-eye 3D images on the display component. The multiple naked-eye 3D images are arranged in different ways.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Before providing a further detailed description of the embodiments of this application, the nouns and terms used in the embodiments of this application are explained, and the nouns and terms used in the embodiments of this application shall be interpreted as follows:

[0042] Autostereoscopy (Naked-eye 3D): This is a general term for technologies that achieve stereoscopic visual effects without the aid of external tools such as polarized glasses.

[0043] Parallax: Parallax refers to the difference in position or orientation of an object within the field of vision when viewed from two different positions. Specifically, it includes positive parallax and negative parallax. Positive parallax occurs when the left-eye image of an object on a display screen is on the left and the right-eye image is on the right. When viewing an object with positive parallax, the perceived image of the object is behind the display screen. Negative parallax occurs when the left-eye image of an object on a display screen is on the right and the right-eye image is on the left. When viewing an object with negative parallax, the perceived image of the object is in front of the display screen.

[0044] Stereoscopic vision involves providing each eye with images exhibiting parallax, which are then synthesized by the brain to create a sense of depth. This is widely recognized as one of the main mechanisms for forming stereoscopic vision. For example, computer devices reproduce image signals with parallax information into images with parallax, thus creating stereoscopic vision for the observer.

[0045] 3D (Three Dimensions) technology adds a dimension to the original two-dimensional plane image, so that the objects seen by the human eye are three-dimensional. Not only is there a distinction between left and right on the plane, but also a distinction between front and back, and near and far. Therefore, the objects we see appear to be three-dimensional.

[0046] Naked-eye 3D images are three-dimensional images that create a stereoscopic effect by utilizing the parallax and convergence function of the two eyes when viewing a display screen at different angles. When a naked-eye 3D image is displayed normally, the observer's left eye sees the image taken from the left perspective, and the right eye sees the image taken from the right perspective. Through the convergence function of the two eyes, they are combined to form a stereoscopic 3D image.

[0047] The naked-eye 3D display device provided in the embodiments of this application will be described in detail below.

[0048] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the naked-eye 3D display device provided in the embodiments of this application.

[0049] The naked-eye 3D display device includes a display component 100 and a parallax grating 200. The display component 100 is disposed on the naked-eye 3D display device, and the parallax grating 200 is disposed directly above the display component 100. The parallax grating 200 is used to adjust the different display contents in the display component 100 to enter different human eyes. A preset distance is set between each pair of adjacent parallax gratings 200. The display area between each pair of pitches is used to display the sub-images corresponding to the multiple naked-eye 3D images on the display component 100. The multiple naked-eye 3D images are arranged in different ways.

[0050] The naked-eye 3D display device provided in this application embodiment is a miniaturized electronic device, such as an electronic cigarette or electronic watch, which is much smaller than the size of electronic devices such as televisions and tablets. Therefore, the size of the entire display component 100 is smaller than the preset size.

[0051] Display component 100 can be a display screen made of any of the following materials: LCD (Liquid Crystal Display), LED (Light Emitting Diode), OLED (Organic Light-Emitting Diode), Micro LED (Micro Light Emitting Diode), or Mini LED (Mini Light Emitting Diode). Display component 100 can also be an e-ink screen.

[0052] The parallax grating 200 can specifically be a lens grating, which is positioned directly above the display component 100. The lens grating can be a cylindrical lens, such as a cylindrical lens, trapezoidal lens, or prismatic lens. When the display component 100 emits light, the cylindrical lens refracts and splits the light, so that the left and right eyes can see different image information when viewing the display component 100 from different angles, thereby producing a naked-eye 3D visual effect and seeing a naked-eye 3D image.

[0053] This application considers the limitations of smaller naked-eye 3D display devices, which restrict the use of larger capacity batteries and more powerful processing chips. To ensure the device can properly display naked-eye 3D images, this application employs a pre-arrangement method for the original image, resulting in naked-eye 3D images with different arrangement options. These images can be displayed by the naked-eye 3D display device, allowing the viewer's brain to perceive the displayed images based on the principle of left-right eye parallax. Because different arrangement options are applied to the original image, the viewer can see the corresponding naked-eye 3D image from various viewpoints, and the content displayed in the naked-eye 3D image is identical to the content of the original image.

[0054] Specifically, please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the sub-images displayed between adjacent pitches of the parallax grating 200 provided in the embodiments of this application.

[0055] A preset pitch is provided between each pair of adjacent parallax gratings 200. The display area between each pair of pitches is used to display the sub-images corresponding to the multiple naked-eye 3D images on the display component 100. The multiple naked-eye 3D images are arranged in different ways.

[0056] In glasses-free 3D display technology, pitch is a crucial parameter. For lenticular lens technology, pitch refers to the distance between the centers of two adjacent lenticular lenses; for parallax barrier technology, pitch refers to the distance between the centers of two adjacent slits (or opaque stripes).

[0057] The pixels corresponding to the sub-images of the naked-eye 3D image under each layout are controlled by the parallax grating 200 and enter different human eyes. Human eyes at different viewpoints can view the sub-images of the naked-eye 3D image under the corresponding layout, thereby realizing the viewing of naked-eye 3D images.

[0058] Since the naked-eye 3D images under different layouts are pre-made, the naked-eye 3D display device only needs to display them without rendering. Therefore, even if the naked-eye 3D display device is miniaturized, it can still display naked-eye 3D images under multiple viewpoints.

[0059] Please see Figure 3 , Figure 3 This is a schematic diagram of the naked-eye 3D display corresponding to the naked-eye 3D display device provided in the embodiments of this application.

[0060] The display component 100 can display naked-eye 3D images under different layouts. The parallax grating 200 can make the pixels corresponding to the left eye of the object enter the left eye and the pixels corresponding to the right eye of the object enter the right eye. Based on the parallax between the left and right eyes, the brain of the object can generate naked-eye 3D images in the brain. Therefore, the human eye can see the naked-eye 3D images displayed by the naked-eye 3D display device.

[0061] Please see Figure 4 , Figure 4 This is another structural schematic diagram of the naked-eye 3D display device provided in the embodiments of this application.

[0062] The naked-eye 3D display device includes a display component 100 and a parallax grating 200. The display component 100 is disposed on the naked-eye 3D display device, and the parallax grating 200 is disposed directly below the display component 100. The parallax grating 200 is used to adjust the different display contents in the display component 100 to enter different human eyes. A preset distance is set between each pair of adjacent parallax gratings 200. The display area between each pair of pitches is used to display the sub-images corresponding to the multiple naked-eye 3D images on the display component 100. The multiple naked-eye 3D images are arranged in different ways.

[0063] Display component 100 may be a display screen made of LCD (Liquid Crystal Display) material. Parallax grating 200 is a slit grating.

[0064] Please combine Figure 5 , Figure 5 This is another structural schematic diagram of the naked-eye 3D display device provided in the embodiments of this application.

[0065] The naked-eye 3D display device includes a backlight module 300 and a parallax grating 200, which is a slit grating disposed between the backlight module 300 and the display component 100.

[0066] When the display assembly is based on LCD material, a backlight module 300 is required for backlight display. At this time, a parallax grating 200 can be set between the backlight module 300 and the display assembly 100 to change the direction of the pixels entering the human eye, so that the left view corresponding to the naked-eye 3D image enters the left eye and the right view corresponding to the naked-eye 3D image enters the right eye.

[0067] Please combine Figure 6 , Figure 6 This is another structural schematic diagram of the naked-eye 3D display device provided in the embodiments of this application.

[0068] These slit gratings act like a barrier, dividing the naked-eye 3D image into two parts: a left-eye image and a right-eye image. When the left-eye image is displayed on the LCD screen, the opaque slit grating blocks the right eye, allowing the left eye to see only the image information belonging to the left eye. Similarly, when the right-eye image is displayed, the slit grating blocks the left eye, thus separating the left and right eye images and allowing the viewer's brain to synthesize these two parallaxed images into a naked-eye 3D image.

[0069] In some cases, setting a parallax grating 200 between the backlight module 300 and the display component 100 can result in a limited viewing angle for the naked-eye 3D image displayed by the naked-eye 3D display device, such as only about 30 to 40 degrees.

[0070] Based on this, the naked-eye 3D display device of this application includes a lens array 400, which is disposed above the display component 100 and is used to adjust the field of view of every two adjacent slit gratings.

[0071] Please refer to the specific details. Figure 7 , Figure 7 This is another structural schematic diagram of the naked-eye 3D display device provided in the embodiments of this application.

[0072] The lens array 400 is positioned above the display component 100 and is used to adjust the field of view between every two adjacent slit gratings. Each lens has a refractive function, which can change the refraction of light corresponding to the pixels displayed by the display component 100, thereby increasing the viewing angle of the naked-eye 3D display device. Specifically, the field of view between every two adjacent slit gratings is 30 degrees to 120 degrees.

[0073] In some embodiments, the display component 100 includes an e-ink screen. The display component 100 does not have the function of emitting light and can only display pixels by reflecting light.

[0074] Please refer to the following: Figure 8 , Figure 8 This is another structural schematic diagram of the naked-eye 3D display device provided in the embodiments of this application.

[0075] The naked-eye 3D display device includes a reflector module 500, which is located directly below the display component 100. The reflector module 500 is used to reflect external light, so that the reflected external light is filtered by the display component 100 and the parallax grating 200 to display multiple naked-eye 3D images.

[0076] In some embodiments, the naked-eye 3D display device also includes a housing, on which the display component 100 and the parallax grating 200 are disposed, and the size of the display component 100 is smaller than a preset size.

[0077] Specifically, please combine Figure 9 , Figure 9 This is a schematic diagram of a glasses-free 3D device provided in an embodiment of this application.

[0079] Specifically, please combine Figure 10 , Figure 10 This is another schematic diagram of the glasses-free 3D device provided in this application embodiment. The glasses-free 3D display device is an electronic watch, and the display component 100 and the parallax grating 200 are disposed on the casing of the electronic watch.

[0082] The display component 100 and parallax grating 200 mentioned above can constitute a glasses-free 3D display screen 10. The glasses-free 3D display screen 10 may also include other components mentioned above, such as... Figure 11 As shown, the naked-eye 3D display screen 10 can be set on the shell of the mobile phone case, specifically on the non-covering surface, that is, the surface facing the outside of the shell, so as to realize the display of naked-eye 3D images on the mobile phone case. The naked-eye 3D images include multiple images, and the naked-eye 3D images under each row can be viewed by the human eye at the corresponding viewpoint.

[0083] In this embodiment, the display component 100 can display multiple naked-eye 3D images with different arrangement methods. A parallax grating 200 is positioned directly above or below the display component 100, with a preset pitch between each pair of adjacent parallax gratings 200. The display area corresponding to each pitch can display sub-images corresponding to the multiple naked-eye 3D images on the display component 100, allowing for adjustment so that the display content of different naked-eye 3D images reaches different human eyes. Compared to the real-time rendering of naked-eye 3D images in related technologies, the naked-eye 3D display device provided in this application does not require computational power for real-time rendering, yet it can achieve naked-eye 3D display of multiple naked-eye 3D images with different arrangement methods.
