Technical Field

The present invention relates to a display system, and more particularly, to a display system capable of simultaneously displaying a planar image and a floating image.

Background

Generally, when a driver operates a vehicle, the driver needs to pay attention to the road condition ahead at any time and also needs to pay attention to the coming vehicle behind or beside the vehicle at any time. However, if the road condition is smooth and monotonous, the driver may feel tired or may feel careless, and thus the driver may not react to the sudden road condition to cause a car accident.

Although a driving assistance system can detect road conditions and give warning or assistance to a driver in time to improve driving safety, if an interface interacting with a user is designed badly, the driver is easily distracted and even dangerous.

Detailed Description

Fig. 1 is a schematic diagram of a display system 100 according to an embodiment of the invention. The display system 100 includes a first display 110, a second display 120, and a floating projection device 130.

The first display 110 has a display surface 110A, and the first display 110 can display the first image IMG1 through the display surface 110A. The second display 120 has a display surface 120A. The second display 120 may simultaneously display the second image IMG2 through the first area 120A1 of the display surface 120A and the third image IMG3 through the second area 120A2 of the display surface 120A.

The overhead projector 130 may be disposed above the display surface 120A and in front of the display surface 110A. The overhead projector 130 may project the overhead image H1 in front of the display surface 110A according to at least the second image IMG2 and the third image IMG 3. The aerial projection device 130 can include a first aerial projection panel 132 and a second aerial projection panel 134. The first floating projection panel 132 may be disposed above the display surface 120A and may reflect the second image IMG2 to project the second image IMG2 on the first plane P1 standing on the display surface 120A to display a first portion of the floating image H1. Similarly, the second floating projection panel 134 may be disposed above the display surface 120A, and may reflect the third image IMG3 to project the third image IM3 on the second plane P2 standing on the display surface 120A to display the second portion of the floating image H1.

In fig. 1, the display surface 110A may be perpendicular to the display surface 120A. In addition, the angle between the first floating projection panel 132 and the display surface 120A may be between 42 and 62 degrees, and the angle between the second floating projection panel 134 and the display surface 120A may also be between 42 and 62 degrees. Furthermore, the first floating projection panel 132 and the second floating projection panel 134 may have a common edge E1, and the included angle between the first floating projection panel 132 and the second floating projection panel 134 may be between 90 degrees and 135 degrees. In this way, the aerial projection device 130 can project the second image IMG2 and the third image IMG3 displayed on the second display 120 onto the first plane P1 and the second plane P2. In some embodiments, the second image IMG2 and the third image IMG3 may respectively represent images of an object in different directions, so that as the position of the viewer moves, different orientations of the object can be observed, creating a floating projection effect.

For example, if the floating image H1 is to be rendered in the shape of a jellyfish, the second image IMG2 may display the right side of the jellyfish, and the third image IMG3 may display the left side of the jellyfish. That is, the overhead projector 130 may project the right and left images of the jellyfish on the first plane P1 and the second plane P2, respectively. So that the observer can see different parts of the jellyfish image when the observer is at different positions, thereby forming the floating image H1.

Fig. 2 is a schematic diagram of a display system 100 according to an embodiment of the present invention applied in a vehicle V1. In fig. 2, the first plane P1 may be toward the driver's seat of the vehicle V1, and the second plane P2 may be toward the passenger's seat of the vehicle V1. That is, the driver and the co-driver can observe different portions of the floating image H1.

In some embodiments, the first display 110 may be a touch screen disposed in the vehicle V1, and the second display 120 may be operated by using a display panel of the mobile device MD 1. In this case, the display system 100 may also include a mount 140. The fixing frame 140 is disposed below the first floating projection panel 132 and the second floating projection panel 134, and is used for accommodating the mobile device MD 1. That is, after entering the vehicle V1, the driver or passenger may place a personal mobile device MD1, such as a smart phone or tablet computer, on the holder 140 and may open the corresponding application. In this way, the second image IMG2 and the third image IMG3 can be displayed by using the display screen of the personal mobile device MD1 as the second display 120, and the second image IMG2 and the third image IMG3 are projected to the first plane P1 and the second plane P2 by the aerial projection device 130 to form the aerial image H1.

In fig. 2, the fixing frame 140 is disposed below the first and second

floating projection panels

132 and 134, and the user can place the display panel of the mobile device MD1 upward on the fixing frame 140 to project the second images IMG2 and IMG3 through the first and second

floating projection panels

132 and 134. However, in some other embodiments, the fixing frame 140 may be disposed above the first floating projection panel 132 and the second floating projection panel 134, and the user may place the display panel of the mobile device MD1 downward on the fixing frame 140 to project the second images IMG2 and IMG3 through the first floating projection panel 132 and the second floating projection panel 134.

In addition, in some embodiments, the floating image H1 and the first image IMG1 may be displayed simultaneously, and the first floating projection panel 132 and the second floating projection panel 134 may reflect the second image IMG2 and the third image IMG3 and may allow the first image IMG1 to penetrate therethrough. That is, the first floating projection panel 132 and the second floating projection panel 134 can be made of a material having both reflectivity and penetrability, such as glass or acrylic. In this case, the user can observe the floating image H1 and the first image IMG1 at the same time.

In some embodiments, the contents of the floating image H1 and the first image IMG1 may be collocated with each other. For example, when the content of the floating image H1 is jellyfish, the first image IMG1 may present a submarine landscape as a background of the floating image H1, that is, the display system 100 may present the floating image H1 and the planar first image IMG1 at the same time to enhance the interactivity of the driving assistance system with the driver and the passenger.

In fig. 1, the display system 100 may also include a processor 150. The processor 150 may generate the content of the first image IMG1 according to the content of the second image IMG2 and the third image IMG 3. In some embodiments, the processor 150 may be the processor 150 in the driving assistance system of the vehicle V1, and may be connected to the first display 110, and display the interactive interface and provide the information required by the user through the first display 110. In this case, the processor 150 and the mobile device MD1 may be connected by wireless or wired connection, and after the user opens the corresponding application program on the mobile device MD1, the processor 150 may generate the content of the corresponding first image IMG1 according to the second image IMG2 and the third image IMG3 displayed on the second display 120. In addition, in other embodiments of the present invention, the processor 150 may also be a processor in the mobile device MD1, and may transmit the first image IMG1 to the first display 110 through wireless or wired communication.

In some embodiments, the floating image H1 may be used to display an avatar of the intelligent driver carried by the vehicle V1, so that when the user gives a command to the intelligent driver through touch, gesture, and voice control …, the avatar presented by the floating image H1, such as the jellyfish shown in fig. 1 and 2, may move accordingly to enhance the interaction with the driver and/or passenger. In addition, when the intelligent driving judges that emergent road conditions occur, the oil quantity is low, vehicle parts are in fault or an important call is made, the color and/or the size of the specific image can be changed to remind a driver, and the driving safety is improved.

In the embodiment of fig. 1 and 2, the aerial projection device 130 may include two

aerial projection panels

132 and 134, and project the images on both sides of the aerial image H1 through the

aerial projection panels

132 and 134, however, in other embodiments of the invention, the aerial projection device 130 may include a greater number of aerial projection panels to provide more aspects of the aerial image H1, increasing the sense of realism when displaying the aerial image H1.

Fig. 3 is a schematic diagram of a display system 200 according to another embodiment of the invention. Display system 200 has a similar structure to display system 100 and may operate according to similar principles. However, the second display 220 of the display system 200 can display the second image IMG2 through the first area 220A1 of the second display surface 220A, display the third image IMG3 through the second area 220A2 of the second display surface 220A, and display the fourth image IMG4 through the third area 220A3 of the second display surface 220A.

In this case, the aerial projection device 230 projects the aerial image H2 in front of the first display surface 110A according to the second image IMG2, the third image IMG3 and the fourth image IMG 4. For example, the aerial projection device 230 may include a first aerial projection panel 232, a second aerial projection panel 234, and a third aerial projection panel 236. The first, second, and third floating

projection panels

232, 234, 236 may be disposed over the second display surface 220A, the first floating projection panel 232 may reflect the second image IMG2 to project the second image IMG2 on the first plane P1 standing on the second display surface 220A to display a first portion of the floating image H2, the second floating projection panel 234 may reflect the third image IMG3 to project the third image IMG3 on the second plane P2 standing on the second display surface 220A to display a second portion of the floating image H2, and the third floating projection panel 236 may reflect the fourth image IMG4 to project the fourth image IMG4 on the third plane P3 standing on the second display surface 220A to display a third portion of the floating image H2.

In some embodiments, the first plane P1 may face toward the driver's seat, the second plane P2 may face toward the passenger's seat, and the third plane P3 may face toward the rear seat. In this way, both the passenger and the driver in the vehicle can observe the corresponding portion of the floating image H2 according to their own positions.

In summary, the display system provided in the embodiments of the present invention can simultaneously present the floating image and the planar image, and can present the specific image of the intelligent driving through the floating image, so as to enhance the interactivity between the driving assistance system and the driver and the passengers, and to facilitate the improvement of the controllability and thus the driving safety.
