Description

Display device and display method

The present invention relates to a display device, in particular to a multi-layer display device for displaying images with multiple vanishing points.

Display devices have been widely used in various electronic devices or equipment to provide information and even operate or input interfaces. Taking a car dashboard as an example, in order to improve the maneuverability of the car, a variety of information can be provided to the driver, so that the driver can control the car in a more detailed manner based on the rich information. Therefore, the display device can be integrated into the car to display various kinds of information to the driver. For example, a conventional mechanical instrument panel can be replaced with a display device.

Single-layer display devices can no longer meet the visual needs of drivers. In order to provide multiple information to the driver while maintaining the visual effect of the three-dimensional pointer of the mechanical instrument panel, a multi-layer display is proposed to meet the three-dimensional image display.

However, multi-layer displays have many problems in image production due to having more than two layers of panels. For example, the lower layer and upper layer images fail to construct stereoscopic vision, the stereoscopic experience is limited to a specific angle of view, or the fidelity is insufficient. Therefore, there is an urgent need in the art for a multi-layer display device capable of displaying realistic images, especially a multi-layer display device that does not see the above-mentioned image infidelity phenomenon at a large viewing angle.

The purpose of the present invention is to provide a multi-layer display device and a display method, so that the displayed images have higher fidelity.

Another object of the present invention is to provide a multi-layer display device and a display method, so that the displayed image can be observed in a wide viewing angle range.

To achieve the above objective, in one aspect of the present invention, a display device may include a first display panel and a second display panel. The first display panel can display a first layer image, and the first layer image can include a first area image and a second area image. The first area image may have a first vanishing point, and the second area image may have a second vanishing point different from the first vanishing point. The second display panel can overlap the first display panel and display the second layer of images. The second layer of images may include a third area image and a fourth area image. The third area image can be superimposed with the first area image to form a first superimposed image. The third region image may have a third vanishing point. The fourth area image can be superimposed with the second area image to form a second superimposed image. The fourth area image may have a fourth vanishing point different from the third vanishing point.

To achieve the above objective, in one aspect of the present invention, a display method may include displaying a first layer image through a first display panel, wherein the first layer image includes a first area image and a second area image, and the first area image having a first vanishing point, the second region image has a second vanishing point different from the first vanishing point; and displaying a second layer of images through a second display panel overlapping with the first display panel, wherein the second layer of images A third area image and a fourth area image are included, wherein the third area image has a third vanishing point, and the fourth area image has a fourth vanishing point different from the third vanishing point.

In the above aspects, since the displayed image has different vanishing points in different regions, the vanishing points of each region can be set according to the viewing angle of the viewer looking at each region. Therefore, even an image of a large viewing angle area for the viewer can provide a realistic image by setting an appropriate vanishing point.

In this document, unless otherwise stated, the ordinal terms "first", "second", "third", etc. are only used to distinguish between different elements or features of the same or similar kind, and do not imply such elements or temporal, spatial, hierarchical, or any other order between features.

FIG. 1 is a schematic diagram of a display device according to some embodiments of the present invention. Referring to FIG. 2 , in some embodiments of the present invention, the display device 100 includes a first display panel 101 and a second display panel 102 . As shown in FIG. 2 , the first display panel 101 and the second display panel 102 are overlapped (that is, the two can be arranged and overlapped in the front view direction of the viewer), and a gap can be sandwiched between them. distance d. In order to clearly illustrate the relationship between the components and the images, the gap distance d in the illustration does not necessarily correspond to the actual situation. The first display panel 101 and the second display panel 102 respectively display the first layer image and the second layer image (for example, the first layer image can be a pointer and a meter frame; the second layer image can be a scale of the meter).

As shown in FIG. 1 , the first display panel 101 is closer to the viewer than the second display panel 102 ; that is, the first display panel 101 and the second display panel 102 are facing the first display panel 101 opposite to the second display panel 102 to display the image in the side direction. In some embodiments, the brightness of the first-layer image displayed on the first display panel 101 is higher than the brightness of the second-layer image displayed on the second display panel 102 . Therefore, the second layer image displayed on the second display panel 102 can be prevented from showing through the first layer image displayed on the first display panel 101, so that the viewer cannot see the part of the lower layer image that should be blocked by the upper layer image in stereoscopic vision. In some embodiments, only the first display panel 101 can display the stereoscopic image, and at this time, the second display panel 102 can display a completely black image.

Since the first display panel 101 and the second display panel 102 overlap, referring to FIG. 2 , when the viewer looks at the display device 100 , he can see the image formed by the overlapping of the first layer of images and the second layer of images ( e.g. complete meter). FIG. 2 shows the superimposed image viewed from approximately a positive viewing angle (perpendicular to the first display panel 101 and the second display panel 102 ), however, the first layer image and the second layer image can be seen within a viewing angle range close to plus or minus 90 degrees The layer images are at least partially overlapped, and images formed by overlapping the first layer image and the second layer image in different degrees can be seen. In other words, the superposition of the first-layer image and the second-layer image The image is not only visible in the range of the adjacent frontal viewing angle, for example, the first layer image and the second layer image can also be seen in the range of a larger viewing angle (such as a viewing angle greater than 60 degrees) to form a three-dimensional visual effect. Overlay images.

In some embodiments, the first display panel 101 and the second display panel 102 may be, for example, a transparent liquid crystal display panel (LCD), a transparent organic light emitting diode display panel (OLED), a transparent micro light emitting diode (Micro LED) The display panel is a transparent sub-millimeter light emitting diode (Mini LED) display panel, although the present invention is not limited to this. The first display panel 101 and the second display panel 102 may also use display panels of different types or different transparency (eg, and the second display panel 102 may be opaque) to match each other.

The first-layer image displayed on the first display panel 101 and the second-layer image displayed on the second display panel 102 may respectively include images of several different regions. For example, as shown in FIG. 1 , in some embodiments, the first display panel 101 may be roughly divided into a first area A1 and a second area A2 , and correspondingly, the first layer of images may include the first area A1 The area image and the second area image in the second area A2; similarly, the second display panel 102 can be roughly divided into a third area A3 and a fourth area A4, and correspondingly, the second layer image can be included in the third area A3 The third area image of , and the fourth area image in the fourth area A4. It should be understood that the present invention is not limited to this. For example, in other embodiments, the first display panel and the second display panel can be divided into different numbers of regions according to the screen contents displayed by them, and superimposed to form different numbers of region images .

As shown in FIG. 2 , when a viewer looks at the display device 100 from an approximately front view angle, it can be seen that the first area A1 and the third area A3 overlap, and the second area A2 and the fourth area A4 overlap. The display device 100 can display an object (eg, a meter) in the overlapping first area A1 and the third area A3, and display another object (eg, another meter) in the overlapping second area A2 and the fourth area A4 .

Referring to FIG. 3A , in some embodiments of the present invention, the first area image displayed in the first area A1 of the first display panel 101 has a first vanishing point VP1 ; the image displayed in the second area A2 of the first display panel 101 has a first vanishing point VP1 . The second area image has a second vanishing point VP2; the third area of the second display panel 102 The third area image displayed by A3 has a third vanishing point VP3; and the fourth area image displayed by the fourth area A4 of the second display panel 102 has a fourth vanishing point VP4. As shown in FIG. 3A , the first vanishing point VP1 is different from the second vanishing point VP2 , and the third vanishing point VP3 is different from the fourth vanishing point VP4 . In other words, the first-layer image displayed on the first display panel 101 has two different vanishing points, and similarly, the second-layer image displayed on the second display panel 102 has two different vanishing points. It should be understood that in other embodiments, each display panel of the present invention may have other numbers of different vanishing points, and the present invention is not limited to this, for example, a superimposed image formed by superimposing the first layer image and the second layer image Objects in each area of can be composed according to the multi-point perspective method, so each area can also have more than 2 vanishing points.

The display device 100 has different vanishing points corresponding to different regions. In other words, the composition of objects in each region can be based only on the vanishing point corresponding to the region where it is located, but not on the vanishing points corresponding to other regions. For example, please refer to FIG. 2 together. 3A and 3B, the meter superimposed on the first area A1 and the third area A3 can be composed only according to the first vanishing point A1 and the third vanishing point A3, but not according to the second vanishing point A2 and the fourth vanishing point A2. Point A4 is used to form a picture, and the opposite is true for the meters superimposed on the first area A1 and the third area A3. Therefore, when the viewer looks at an object displayed by the display device 100 from a large viewing angle, he will not see an unrealistic phenomenon (for example, after the lower layer image and the upper layer image are superimposed, there is no stereoscopic view between them. A transitional picture that should exist visually (such as a picture of a side elevation of an object), or the outlines of the upper and lower images protrude or shrink in relation to each other in a way that does not conform to stereoscopic vision).

Referring to FIG. 3A again, in some embodiments, the first area image displayed in the first area A1 has a first perspective direction D1. As shown in FIG. 3A , when looking at the overlapping first area A1 and the third area A3 from the first perspective direction D1 , the line of sight will pass through the first vanishing point VP1 and also the third vanishing point VP3 . In other words, in the first perspective direction D1, the first vanishing point VP1 and the third vanishing point VP3 overlap. Similarly, the second area image displayed in the second area A2 has a second perspective direction D2, and in the second perspective direction D2, the second vanishing point VP2 and the fourth vanishing point VP4 coincide.

Referring to FIG. 3B , in some embodiments, the first vanishing point VP1 and the third vanishing point VP3 are substantially the same, and the second vanishing point VP2 and the fourth vanishing point VP4 are substantially the same.

Referring to FIGS. 4A-4C, as shown in FIG. 4A, in some embodiments, the first layer of images displayed on the first panel 101 may include images of objects (eg, the first object OB1, the second object OB2, and the third object OB2). Object OB3), as shown in FIG. 4B , the second layer image displayed on the second display panel 102 may include shadow images (eg, the first shadow SHA1, the second shadow SHA2, and the third shadow SHA3). As shown in FIG. 4C , when the first layer image displayed by the first panel 101 in FIG. 4A and the second layer image displayed by the second display panel 102 in FIG. 4B are superimposed, a shadowed object can be formed. An image (eg, the image of the first object OB1 with the first shadow SHA1, etc.). In these embodiments, the range of the shadow images (eg, the first shadow SHA1, the second shadow SHA2, and the third shadow SHA3) in the second layer image displayed by the second display panel 101 is derived from the object image (eg, the first shadow SHA3). An object OB1, a second object OB2, and a third object OB3) extend an extension length (eg, the first extension length ext1, the second extension length ext2, and the third extension length) on the edge of the orthographic projection on the second display panel 102 length ext3).

In some embodiments, the ratio of the extended length of the shadow image to the gap distance between the first display panel 101 and the second display panel 102 (eg, the gap distance d shown in FIG. 1 ) ranges from 1/7 to 5/7 In between, it can make the viewer feel more natural. For example, when the gap distance d is 7 mm, the first extension length ext1 , the second extension length ext2 , and the third extension length ext3 may fall within the range of 1 mm to 5 mm.

Referring to FIG. 5 , the object OB is, for example, a three-dimensional image formed by superimposing the first-layer image displayed on the first display panel 101 and the second-layer image displayed on the second display panel 102 . FIG. 5 shows the object OB viewed from a large viewing angle. As shown in FIG. 5 , in some embodiments, the image of the object OB (eg, instrument) formed by superimposing the first layer image displayed on the first display panel 101 and the second layer image displayed on the second display panel 102 There may be a façade image SW (eg the side wall of the meter frame). Therefore, the stereoscopic image displayed by the display device 100 can avoid phenomena such as image discontinuity.

Since the façade image needs to have a visual experience spanning different depths in stereoscopic vision, the façade image needs to be displayed by the first-layer panel and the second-layer panel at different distances from the viewer. Referring to FIG. 6A , FIG. 6A shows an upper-section elevation image sw_u that can be displayed by the first display panel 101 when viewed from a front view. Referring to FIG. 6B , FIG. 6B shows the lower-section elevation image sw_d which can be displayed by the second display panel 102 when viewed from the front view. Referring to FIG. 6C , the elevation image SW can be superimposed by the upper elevation image sw_u in the first layer image displayed by the first display panel 101 and the lower elevation image sw_d in the second layer image displayed by the second display panel 102 form.

In some embodiments, the orthographic projection of the upper elevation image sw_u on the second display panel 102 at least partially overlaps with the lower elevation image sw_d (eg, the shaded portion shown in FIG. 6C ). For example, in some cases, In an embodiment that the viewer feels more natural, the overlapping width wov of the shaded portion shown in FIG. 7 may be 15-40% of the width wsw of the elevation image SW. The above are only examples, and the present invention is not limited to the above numerical values.

The transparency of the upper elevation image sw_u is greater than the transparency of the lower elevation image sw_d. For example, in some embodiments that can make the viewer feel more natural, the opacity of the upper elevation image sw_u may be 34%, and the lower elevation image sw_d may be 34%. The opacity of the face image sw_d can be 45%. The above are only examples, and the present invention is not limited to the above numerical values.

In some embodiments, the width of the orthographic projection of the upper elevation image sw_u (for example, the width wu of the upper elevation) is smaller than the width of the lower elevation image sw_d on the virtual section line L crossing the orthographic projection of the upper elevation image sw_u and the lower elevation image sw_d The width of the elevation image sw_d (for example, the width of the lower elevation wd). The above are only examples, and the present invention is not limited to the above numerical values.

In some embodiments, one of the display parameters of the orthographic projection of the upper elevation image sw_u and the lower elevation image sw_d is gradually changed along a virtual intercept line L that crosses the orthographic projection of the upper elevation image sw_u and the lower elevation image sw_d. For example, the orthographic projection of the upper elevation image sw_u and the color or brightness parameter of the lower elevation image sw_d may gradually increase along the section line L from the center of the elevation image SW to the periphery of the elevation image SW or decreasing. In addition, in one embodiment, the façade image SW can have an image effect of soft edges (eg, feathering), so as to make the viewer feel more realistic.

Stereoscopic images need to have a visual effect of depth (or near and far). For example, objects that are farther from the viewer to be displayed in the image need to make the viewer feel deeper, and vice versa, it needs to make the viewer feel closer. In a multi-layer display of the present disclosure, such as display device 100, a display panel closer to the viewer may be used to display objects with a smaller depth, while a display panel further away from the viewer may be used for objects with a larger depth the display. Referring to FIG. 7A , FIG. 7A shows a first layer image pic_u with a smaller depth displayed by the first display panel 101 . Referring to FIG. 7B , FIG. 7B shows the second layer image pic_d with a larger depth displayed by the second display panel 102 . Referring to FIG. 7C , the superimposed image pic is, for example, a three-dimensional image formed by superimposing the first layer image pic_u and the second layer image pic_d. In some embodiments, the first-layer image displayed on the first display panel 101 and the second-layer image displayed on the second display panel 102 may respectively have several layers, and each layer presents different depths in stereoscopic vision. For example, as shown in FIG. 8 , the picture pic has a first-level surface p1, a second-level surface p2, a third-level surface p3, and a fourth-level surface p4, which can be images of four different layers respectively.

In different embodiments, the first-level surface p1, the second-level surface p2, the third-level surface p3, and the fourth-level surface p4 may be included in the first-level image or the second display displayed by the first display panel 101, respectively. In the second layer image displayed on the panel 102 . For example, in one embodiment, the first layer of image displayed on the first display panel 101 may include the first level surface p1 and the second level surface p2, and the second level image displayed by the second display panel 102 may include The third-level surface p3 and the fourth-level surface p4 (that is, the first-layer image and the second-layer image respectively include two layers); in another embodiment, the first-layer image displayed on the first display panel 101 The first level surface p1 may be included, and the second level image displayed by the second display panel 102 may include the second level surface p2, the third level surface p3, and the fourth level surface p4 (ie, the first level image contains 1 layer, and the second image contains 3 layers). In some embodiments, the first-layer image displayed by the first display panel 101 may have a value lower than 45% of the total number of layers (ie, the sum of the number of layers of the first-layer image and the second-layer image). number of layers (ie, The image depth of the first layer image is less than 45% of the image depth of the superimposed image) to provide a more realistic three-dimensional image. In other words, the first-layer image displayed on the first display panel 101 may have a smaller number of layers than the second-layer image displayed on the second display panel 102, so as to provide a more realistic three-dimensional image.

Referring to FIG. 8, in one aspect of the present invention, the display method 900 may include steps S901-S902. The display method 900 may be performed by the display device 100, for example. In step S901, the first layer image can be displayed through the first display panel 101, wherein the first layer image includes a first area image and a second area image, the first area image has a first vanishing point (eg VP1), The two-region image has a second vanishing point (eg, VP2) that is different from the first vanishing point. Next, in step S902, the second layer image can be displayed through the second display panel 102 overlapping the first display panel 102, wherein the second layer image includes the third area image and the fourth area image, and wherein the first layer image The three-region image has a third vanishing point (eg, VP3), the fourth-region image has a fourth vanishing point (eg, VP4) that is different from the third vanishing point, and the first-layer image and the second-layer image overlap to form a superimposed image .
