[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] See also Figure 1 and Figure 2 In the virtual display, imaging light is emitted from the light source 14, passes through the screen and reaches the user's eyes. The user looks against the screen and sees an enlarged display virtual image 400 in the distance through the screen.

[0041] As the user's position changes, the angle between his or her line of sight and the edge of the screen will also change, and the imaging light received by the eyes will also change. Therefore, the virtual image seen by the user will shift as the user's position changes.

[0042] Taking the light point A on the light source 14 as an example, the virtual image 400 has an image point A' corresponding to the light point A. When the user is at one position, the observed image point A' is formed by a beam of imaging light emitted by the light point A passing through the screen to the user's eyes, and the intersection of the imaging light and the screen is A1; when the user is at another position, the observed image point A' is formed by another beam of imaging light emitted by the light point A passing through the screen to the user's eyes, and the intersection of the imaging light and the screen is A2; and so on, a plurality of imaging light beams emitted by the light point A pass through the set of screen intersections to form the A region 500, and when the user is at different positions, the imaging light received by his eyes is the imaging light passing through one point of the A region 500, so the points on the screen of the virtual display device cannot be mapped one-to-one with the points on the virtual image 400.

[0043] Assume that the light point B on the light source 14 corresponds to the image point B' and the area B 600 on the screen, and that the area B 600 and the area A 500 have an intersection area. When the screen is touched, a point in the intersection area is touched, which corresponds to the two image points A' and B' at the same time. In addition, the user's left and right eyes are in different positions, and receive two beams of imaging light corresponding to the same image point. The intersection of the two beams of imaging light and the screen does not coincide, so it is impossible to use touch operation for human-computer interaction.

[0044] In view of this, the present invention provides a virtual display 100 .

[0045] See also Figure 3 The virtual display 100 includes a display body 1, a touch device 2, an infrared sensing device 3 and a control device; the display body 1 includes a window mirror 11, the window mirror 11 is used to transmit imaging light to form a display virtual image 400, and the side where the imaging light emerges is the light-emitting side; the touch device 2 is arranged on the window mirror 11, and a touch surface is formed on the window mirror 11, and the touch device 2 is used to detect the user's touch operation; the infrared sensing device 3 is arranged on the light-emitting side of the window mirror 11, and is used to detect the corresponding position of the user's finger on the window mirror 11; the control device is electrically connected to the display body 1, the touch device 2 and the infrared sensing device 3.

[0046] The technical solution of the present invention uses the display body 1 to emit imaging light to form a display virtual image 400 in the user's eyes. When the user performs a touch operation, the finger first moves in the sensing area of ​​the infrared sensing device 3. At this time, the infrared sensing device 3 detects the corresponding position of the user's finger on the window mirror 11 in real time, and sends the sensing information to the control device. The control device controls the display body 1 to display the virtual image position corresponding to the current position of the user's finger. When the user's finger moves, the displayed virtual image position also moves in the displayed virtual image 400. When the user moves his finger until the virtual image position reaches the target virtual image position, the finger performs a touch operation on the touch surface. At this time, the touch device 2 senses the touch operation type and sends the sensing information to the control device. The control device controls the display body 1 to implement the corresponding function; the user's finger position is corresponded to the virtual image position in the displayed virtual image 400 in real time, and the virtual image 400 position is displayed, so that the user can receive feedback before performing the touch operation, and the position of the touch operation is determined according to the feedback, thereby realizing accurate touch operation of the virtual image display and realizing human-computer interaction in the virtual image display.

[0047] The touch control device 2 and the infrared sensing device 3 are prior art, and their specific structures are not described in detail.

[0048] See also Figure 6 In one embodiment of the present invention, the control device includes a memory, a processor, and a virtual display touch program stored in the memory, and the processor executes the virtual display touch program to implement the following virtual display touch method:

[0049] Step S10: obtaining the current position of the user's finger on the window mirror 11 detected by the infrared sensing device 3;

[0050] Step S20: Displaying a virtual image position corresponding to the current position of the user's finger on the display body 1;

[0051] Step S30: when the virtual image position reaches the target virtual image position and the user's finger touches the touch surface, the current position of the user's finger is determined to be the touch position.

[0052] In one embodiment of the present invention, the window mirror 11 has a first direction and a second direction, the size of the window mirror 11 along the first direction is a, and the size of the window mirror 11 along the second direction is b;

[0053] The virtual image 400 displayed by the virtual display 100 has a first virtual image direction corresponding to the first direction and a second virtual image direction corresponding to the second direction. The length of the virtual image 400 displayed by the virtual display 100 along the first virtual image direction is c, and the length along the second virtual image direction is d.

[0054] The coordinate of the current position of the user's finger along the first direction is w, and the coordinate along the second direction is h; the coordinate of the virtual image position along the first virtual image direction is x, and the coordinate along the second virtual image direction is y;

[0055] In the step of displaying the virtual image position corresponding to the current position of the user's finger on the display body 1, the corresponding relationship between the virtual image position displayed by the display body 1 and the current position of the user's finger is:

[0056]

[0057] In one embodiment of the present invention, when the virtual image position reaches the target virtual image position and the user's finger touches the touch surface, the step of determining the current position of the user's finger as the touch position includes:

[0058] Step S31: receiving a touch operation of a user's finger at a touch position;

[0059] Step S32: Execute corresponding functions according to the touch operation.

[0060] In one embodiment of the present invention, touch operations include click operations, long press operations, and click-and-slide operations; functions corresponding to touch operations include selection functions, option functions, and drag functions; the selection function corresponds to the click operation, the option function corresponds to the long press operation, and the drag function corresponds to the slide operation.

[0061] In one embodiment of the present invention, the touch device 2 includes a capacitive film, and the capacitive film is attached to the surface of the window mirror 11. The use of a capacitive sensing touch device 2 has a higher resolution and a more sensitive response.

[0062] See also Figure 3 and Figure 4In one embodiment of the present invention, the display body 1 further includes a light source 14, an inner window glass 13 and a curved mirror 12; the light source 14 is arranged on a side of the window mirror 11 facing away from the touch device 2; the inner window glass 13 is arranged between the light source 14 and the window mirror 11, and is arranged opposite to the window mirror 11, and a first quarter wave plate 131 is bonded to one side of the inner window glass 13; the curved mirror 12 is arranged between the inner window glass 13 and the window mirror 11, and is arranged opposite to the window mirror 11, and a dichroic film 121 is bonded to one side of the curved mirror 12; on a side of the window mirror 11 facing the curved mirror 12, a first reflective polarizer 111 and a second quarter wave plate 112 are bonded in sequence along a direction away from the window mirror 11.

[0063] In the figure, the straight line on the reflective polarizer is the reflection axis direction, and the transmission axis direction is perpendicular to the reflection axis direction; the straight line on the quarter-wave plate is the slow axis direction; and the straight line on the linear polarizer is the absorption axis direction.

[0064] The first quarter wave plate 131, the second quarter wave plate 112 and the first reflective polarizer 111 are arranged so that the splitter film 121 transmits the imaging light that arrives at the curved mirror 12 for the first time, and reflects the imaging light that is reflected from the window mirror 11 to the curved mirror 12 for the second time and arrives at the curved mirror 12; the window mirror 11 is used to reflect the imaging light that arrives at the window mirror 11 for the first time to the curved mirror 12, and transmits the imaging light that is reflected from the curved mirror 12 to the window mirror 11 for the second time and arrives at the window mirror 11.

[0065] The path of the imaging light is as follows: the imaging light emitted by the image source passes through the inner window glass 13 and the curved mirror 12 in turn and reaches the window mirror 11, is reflected by the window mirror 11 and reaches the curved mirror 12 again, is reflected back to the window mirror 11 by the curved mirror 12, and is emitted from the window mirror 11, forming a long-distance magnified virtual image in the user's perspective.

[0066] Specifically, the first quarter wave plate 131 is disposed perpendicular to the slow axis direction of the second quarter wave plate 112 , and the slow axis direction of the second quarter wave plate 112 is disposed at an angle of 45° or 135° to the reflection axis of the first reflective polarizer 111 .

[0067] See also Figure 4 Furthermore, a first linear polarizer 132 is disposed between the first quarter wave plate 131 and the inner window glass 13, and the angle between the slow axis direction of the first quarter wave plate 131 and the absorption axis of the linear polarizer is 45°, so that circularly polarized light can be emitted.

[0068] See also Figure 5Further, the beam splitter film 121 is arranged on the concave side or the convex side of the curved mirror 12, an anti-reflection film 15 is arranged on the side of the second quarter wave plate 112 away from the window mirror 11, and an anti-reflection film 15 is arranged on the side of the first quarter wave plate 131 away from the inner window glass 13 and on the side of the inner window glass 13 close to the light source 14, so as to reduce reflection and enhance light effect.

[0069] Furthermore, a second linear polarizer 113 is disposed between the first reflective polarizer 111 and the window mirror 11 to eliminate ghost images formed by light leakage due to insufficient extinction ratio of the self-reflection axis.

[0070] Further, on the side of the window mirror 11 away from the curved mirror 12, a third quarter wave plate 114 and a third linear polarizer 115 are sequentially arranged along the direction away from the curved mirror 12, the third quarter wave plate 114 forms a 45° angle or a 135° angle with the absorption axis of the second linear polarizer 113, and the third linear polarizer 115 forms a 0° angle or a 90° angle with the absorption axis of the second linear polarizer 113. The third quarter wave plate 114 and the third linear polarizer 115 form an AR circular polarizer, which can reduce the reflection of the window mirror 11 to the external ambient light, so as to reduce the influence of the external ambient light on the imaging.

[0071] Furthermore, a capacitive screen is used to replace the capacitive film and the window mirror 11 , and the above-mentioned film material is attached to the capacitive screen to achieve good imaging function and touch function, or the above-mentioned film material and the capacitive film are attached to the window mirror 11 in sequence.

[0073] Among them, mobile devices include mobile phones, tablets and other devices. The interface uses the OTG interface to achieve touch expansion. When using it, you need to turn on the "touch display" function in the mobile phone or tablet system, that is, to display the touch position in real time. For computer display screens, the corresponding host can also achieve touch expansion through the USB interface to replace the mouse function.

[0074] In one embodiment of the present invention, the light source 14, the inner window glass 13, the curved mirror 12 and the window mirror 11 are relatively movable, and the movable direction is along the main light direction of the imaging light. The virtual display image can be adjusted by adjusting the distance between the inner window glass 13, the curved mirror 12 and the window mirror 11.

[0075] The invention also provides a touch control method for a virtual display.

[0078] Step S20: Displaying a virtual image position corresponding to the current position of the user's finger on the display body 1;

[0079] Step S30: when the virtual image position reaches the target virtual image position and the user's finger touches the touch surface, the current position of the user's finger is determined to be the touch position.

[0080] In this way, when the user uses a virtual display with this method, the finger first moves in the infrared detection area of ​​the infrared sensing device 3, and then determines whether it has reached the target virtual image position based on the corresponding virtual image position displayed by the display body 1, so that the user can receive real-time feedback to determine whether his current position is the position he wants to touch. If so, he operates on the touch surface, thereby accurately realizing the human-computer interaction of the virtual display.
