Description

Technical Field

[0001] This invention relates to a stereoscopic display device and a display method for the stereoscopic display device. Background Technology

[0002] In the field of three-dimensional (3D) display technology, how to break through the limitations of traditional flat-panel displays and provide viewers with a more immersive, realistic, and stereoscopic visual experience that is not limited by specific viewing angles has always been the direction that related industries have been striving to develop. Currently, most applications utilize large screens at the corners of buildings to create a naked-eye 3D effect through visual displacement, but their viewing angles and image presentation methods are still limited. Summary of the Invention

[0003] This invention proposes a stereoscopic display device and its display method, aiming to improve the limitations of traditional naked-eye 3D displays, which can only be viewed from a fixed direction and have insufficient depth of field. It provides a display solution that can be viewed from multiple angles, and at the same time combines the naked-eye 3D effect with the stereoscopic depth of field presented by the superposition of physical space, making the overall visual experience more realistic.

[0004] At least one embodiment of the present invention provides a stereoscopic display device. The stereoscopic display device includes first to third double-sided transparent displays that laterally surround a permeable region. The first double-sided transparent display includes a first display surface and a second display surface opposite to the first display surface. The second double-sided transparent display includes a third display surface and a fourth display surface opposite to the third display surface. The third double-sided transparent display includes a fifth display surface and a sixth display surface opposite to the fifth display surface. The second display surface of the first double-sided transparent display overlaps the included angle between the second and third double-sided transparent displays in a first direction perpendicular to the second display surface.

[0005] At least one embodiment of the present invention provides a display method for a stereoscopic display device, comprising the following steps: Providing the stereoscopic display device. A user faces one of a first double-sided transparent display, a second double-sided transparent display, and a third double-sided transparent display, and the included angle between the other two of the first, second, and third double-sided transparent displays. The first, second, and third double-sided transparent displays display a stereoscopic image to the user.

[0006] Based on the above design, a naked-eye 3D effect can be presented by combining the first to third double-sided transparent displays, and the performance of stereoscopic depth of field can be improved at the same time, making the overall visual experience more realistic and vivid.

These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, the “first element,” “component,” “region,” “layer,” or “part” discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of this document.

[0025] Figure 1 This is a perspective view of a stereoscopic display device 10 according to an embodiment of the present invention. (See reference) Figure 1 The stereoscopic display device 10 includes a first double-sided transparent display 100, a second double-sided transparent display 200, and a third double-sided transparent display 300 that horizontally surround the penetrating area TR.

[0026] The first double-sided transparent display 100 includes a first display surface 101 and a second display surface 102 opposite to the first display surface 101. The second double-sided transparent display 200 includes a third display surface 203 and a fourth display surface 204 opposite to the third display surface 203. The third double-sided transparent display 300 includes a fifth display surface 305 and a sixth display surface 306 opposite to the fifth display surface 305. The first display surface 101, the third display surface 203, and the fifth display surface 305 face outwards (or are said to face away from the penetration area TR), and therefore can also be called outer display surfaces. The second display surface 102, the fourth display surface 204, and the sixth display surface 306 face inwards (or are said to face the penetration area TR), and therefore can also be called inner display surfaces. The outer display surface of each double-sided transparent display faces away from the other two double-sided transparent displays, and the inner display surface of each double-sided transparent display faces the included angle between the other two double-sided transparent displays.

[0027] The first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 are connected together. The first double-sided transparent display 100 is connected to the second double-sided transparent display 200, the second double-sided transparent display 200 is connected to the third double-sided transparent display 300, and the third double-sided transparent display 300 is connected to the first double-sided transparent display 100.

[0028] The first display surface 101 is connected to the third display surface 203, the third display surface 203 is connected to the fifth display surface 305, and the fifth display surface 305 is connected to the first display surface 101; the second display surface 102 is connected to the fourth display surface 204, the fourth display surface 204 is connected to the sixth display surface 306, and the sixth display surface 306 is connected to the second display surface 102. In some embodiments, there are seams between the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300, but this disclosure is not limited thereto. In other embodiments, the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 are seamlessly spliced ​​together, making the displayed image more continuous.

[0029] The first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 can be any type of double-sided transparent display, such as a micro light-emitting diode double-sided transparent display, an organic light-emitting diode double-sided transparent display, or other types of double-sided transparent displays. In a double-sided transparent display, transparent areas are provided between pixels, allowing the user to see the environment behind the display through these areas. Furthermore, in a double-sided transparent display, some pixels are configured to display an image on the outer display surface, while others are configured to display an image on the inner display surface. The outer and inner display surfaces of each double-sided transparent display can display different images. In other words, different images can be seen when viewing the double-sided transparent display from different sides.

[0030] Furthermore, when displaying images, the perspective effect of different areas in a double-sided transparent display changes with brightness. When a certain area of ​​the screen is brighter, its transparency decreases, preventing the user's gaze from penetrating the bright area to see objects behind it. Conversely, areas with lower brightness or no light emission maintain higher transparency, allowing the user to directly observe the underlying environment through these low grayscale areas. In other words, the displayed content simultaneously acts as both an "image" and an "obscuring element," with the distribution of light and dark determining the range the user can see, creating a dynamic transparency / opaque switching effect. This characteristic allows double-sided transparent displays to retain some background visual information while displaying images, making them suitable for applications that require combining virtual and real scenes, such as display cases, wayfinding interfaces, and augmented reality windows.

[0031] Figure 2A This is a top view of a stereoscopic display device 10 and a user U according to an embodiment of the present invention. Please refer to...

In this embodiment, the included angles θ1 between the first double-sided transparent display 100 and the second double-sided transparent display 200, θ2 between the second double-sided transparent display 200 and the third double-sided transparent display 300, and θ3 between the third double-sided transparent display 300 and the first double-sided transparent display 100 are approximately 60 degrees. In other words, the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 are arranged in an equilateral triangle.

[0032] The second display surface 102 overlaps with the angle θ2 between the second double-sided transparent display 200 and the third double-sided transparent display 300 in a first direction D1 perpendicular to it. The fourth display surface 204 overlaps with the angle θ3 between the third double-sided transparent display 300 and the first double-sided transparent display 100 in a second direction D2 perpendicular to it. The sixth display surface 306 overlaps with the angle θ1 between the first double-sided transparent display 100 and the second double-sided transparent display 200 in a third direction D3 perpendicular to it.

[0033] In some embodiments, the angle between the first display surface 101 and the third display surface 203 is less than 90 degrees, and the angle between the first display surface 101 and the third display surface 203 may be an acute angle or a rounded corner of approximately 60 degrees. Similarly, the angle between the third display surface 203 and the fifth display surface 305 is less than 90 degrees, and the angle between the third display surface 203 and the fifth display surface 305 may be an acute angle or a rounded corner of approximately 60 degrees. In some embodiments, the angle between the second display surface 102 and the fourth display surface 204 may be an acute angle or a rounded corner of approximately 60 degrees. The angle between the fourth display surface 204 and the sixth display surface 306 may be an acute angle or a rounded corner of approximately 60 degrees. The angle between the sixth display surface 306 and the second display surface 102 may also be an acute angle or a rounded corner of approximately 60 degrees.

[0034] User U faces one of the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300, as well as the angle between the other two of the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300. Figure 2A In one embodiment, the user U faces the second display surface 102 of the first double-sided transparent display 100 and the angle between the second double-sided transparent display 200 and the third double-sided transparent display 300.

The naked-eye 3D image displayed on the third display surface 203 and the fifth display surface 305 of the second double-sided transparent display 200 is superimposed on the second display surface 102 of the first double-sided transparent display 100 to obtain a stereoscopic depth effect, making the overall visual experience more realistic and vivid.

It should be noted that... Figures 2B to 2D This is only used to illustrate the overlay of images and does not specifically demonstrate the 3D effect or depth of field of the images.

[0037] exist Figures 2A to 2D In this embodiment, the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 of the stereoscopic display device 10 display a stereoscopic image M1 to the user U. The user U faces the second display surface 102 of the first double-sided transparent display 100, and the user U faces the angle between the third display surface 203 of the second double-sided transparent display 200 and the fifth display surface 305 of the third double-sided transparent display 300. The second display surface 102 is farther away from the user U than the third display surface 203 and the fifth display surface 305.

[0038] The second display surface 102 displays the background image B1 to the user U, and the third display surface 203 and the fifth display surface 305 display the object O1 to the user U.

[0039] exist Figure 2A In this embodiment, from the user U's perspective, the angle formed by the third display surface 203 of the second double-sided transparent display 200 and the fifth display surface 305 of the third double-sided transparent display 300 allows the object O1 to have a naked-view 3D effect. The object O1 is superimposed on the background image B1 displayed on the second display surface 102 to obtain a stereoscopic depth effect, making the overall visual experience more realistic and vivid.

[0040] One angle of the stereoscopic display device 10 (i.e., the angle between the second double-sided transparent display 200 and the third double-sided transparent display 300) faces the user U, allowing the user to perceive that the object O1 appears to emerge from the image and approach them. In other words, the stereoscopic display device 10 is particularly suitable for displaying a forward-protruding, floating object O1 when viewed from its angle. For example, the user U can perceive a stereoscopic effect of the object O1 (such as a turtle) swimming outward from the background image B1.

Figure 3D yes Figure 3A This is a schematic diagram of the foreground image F2 displayed on the first display surface 101 of the first double-sided transparent display 100 of the stereoscopic display device 10. It should be noted that... Figures 3B to 3D This is only used to illustrate the overlay of images and does not specifically demonstrate the 3D effect or depth of field of the images.

[0042] exist Figures 3A to 3D In this embodiment, the first double-sided transparent display 100, the second double-sided transparent display 200, and the third double-sided transparent display 300 of the stereoscopic display device 10 display a stereoscopic image M2 to the user U. The user U faces the first display surface 101 of the first double-sided transparent display 100, and the user U faces the angle between the fourth display surface 204 of the second double-sided transparent display 200 and the sixth display surface 306 of the third double-sided transparent display 300. The first display surface 101 is closer to the user U than the fourth display surface 204 and the sixth display surface 306.

[0043] The first display surface 101 displays the foreground image F2 to the user U, and the fourth display surface 204 and the sixth display surface 306 display the object O2 to the user U.

[0044] exist Figure 3A In this embodiment, from the user U's perspective, the angle formed by the fourth display surface 204 of the second double-sided transparent display 200 and the sixth display surface 306 of the third double-sided transparent display 300 allows the object O2 to have a naked-view 3D effect. The object O2 is superimposed on the foreground image F2 displayed on the first display surface 101 to obtain a stereoscopic depth effect, making the overall visual experience more realistic and vivid.

[0045] One side of the stereoscopic display device 10 (i.e., the first display surface 101) faces the user U, allowing the user to perceive that the object O2 appears to be embedded in the foreground image F2 displayed on the first display surface 101 and moving away from itself. In other words, when viewed from the side of the stereoscopic display device 10, it is particularly suitable for presenting an inwardly recessed object O2. For example, the user U can perceive a stereoscopic effect of the object O2 (such as two birds) embedded in the foreground image F2.

[0046] In some embodiments, the object O2 displayed on the first display surface 101 overlaps with the low grayscale area LL (or low brightness area) of the foreground image F2. Since the low grayscale area LL has low brightness or is completely dark, the object O2 is prevented from being blocked by the foreground image F2 and becoming blurry. In some embodiments, the brightness of the low grayscale area LL is less than 30 nits.

Since surround-view applications rely on multiple display surfaces to form a complete image, the content displayed on adjacent display surfaces in the connecting area must remain substantially continuous. "Substantially continuous" means that even if there are slight seams between adjacent display surfaces, causing a slight interruption in the image at the seam, such interruption is not enough to affect the overall visual performance, nor will it disrupt the user's perception of the continuity of the complete image.
