Panorama-Headup-Display

Abstract

A panoramic head-up display comprising a reflector mirror mounted on a dashboard and several flat display modules mounted below the reflector mirror, wherein the reflector mirror is positioned between the left and right edges of the dashboard and is further equipped with a mirror base attached to the dashboard behind the reflector mirror and a transparent protective cap for support in front of the reflector mirror, wherein the reflective surface of the reflector mirror has low reflectivity, so that the reflector mirror does not reflect light from the dashboard and can still absorb the light passing through the reflective surface of the reflector mirror to eliminate any ghosting. This allows the image rays to be projected from each flat display module onto the reflector mirror and then reflected via the reflector mirror to the eyes of a viewer.

Description

[Technology field]

[0001] The invention relates to a panoramic head-up display, in particular one whose reflector mirror replaces a light-shielding zone at the lower edge of the windscreen and then serves as a reflective assembly to produce a similar or better demonstration effect than a curved panoramic display in the prior art, which extends from the left A-pillar to the right A-pillar. [Background of the invention]

[0002] The windshield of a motor vehicle is attached to the body using adhesive strips and sealants. However, it is inevitable that these adhesive strips and sealants will age with prolonged exposure to sunlight. In this case, a light-shielding zone is arranged at the edge of the windshield. This light-shielding zone is formed using a ceramic sintering process, similar to that used for ceramic-textured glass with a dark glaze applied. As shown in the diagram... Fig. 1A and Fig. As shown in Figure 1B, the black light-shielding zone (LSR) is just sufficient to cover the adhesive strips and sealant, blocking direct sunlight and thus protecting the adhesive strips and sealant from premature aging or damage. This ensures the proper service life of the adhesive strips and sealant.

[0003] In addition to protecting the adhesive strips and sealants from aging, the prior art also includes the installation of a curved display field CDP with reference to Fig. 2A and Fig. 2B is possible by increasing the area of ​​the light shielding zone LSR at the lower edge of the windscreen 6, or between L-AP of the left A-pillar and R-AP of the right A-pillar, provided that the area around the visible viewing angle θd remains unobstructed according to the technical specifications. The curved display field CDP extends from L-AP of the left A-pillar to R-AP of the right A-pillar, thus forming a panoramic display that can provide the driver and passengers with desired information about the vehicle status, navigation, and other data. However, it should be noted that a curved display field CDP is expensive and therefore very difficult to implement in a large number of vehicle models.

[0004] In the prior art, another panoramic head-up display is also known, wherein the light-shielding zone LSR at the lower edge of the windshield 6 serves as a reflector mirror, below which a flat display module 3 is located, as in Fig. 3A is shown, attached. This allows the image rays D to be projected through the flat display module 3 onto the light-shielding zone LSR and then reflected through the light-shielding zone LSR to the eyes E of the driver and / or passengers, so that the viewer's eyes E see the virtual images VI behind the light-shielding zone LSR of the windshield 6. In this context, the panoramic head-up display can already show desired information about the vehicle status, navigation, and other data, as shown in, without a costly curved display area. Fig. 3B shown, make available.

[0005] However, this panoramic head-up display is only feasible for the windshield of a conventional passenger car, since the angle θw, as in Fig. Figure 3A shows that the angle between the windshield and the dashboard of an ordinary passenger car is approximately 30 degrees. In a sports car, according to... Fig. However, this is difficult for 3C because the angle θw between the windshield 6 and the dashboard ID is relatively small, for example, about 20 degrees. This means that the image rays D coming from the light shielding zone LSR cannot be projected to the viewer's eyes E due to the projection angle being too small after passing through the light shielding zone LSR. If the flat display module 3 were adjusted so that the image rays could be reflected through the light shielding zone LSR to the viewer's eyes E, this would interfere with the fire wall and the viewing angle would become relatively smaller both upwards and downwards. [Description of the invention]

[0006] The object of the invention is to provide a panoramic head-up display in which the light-shielding zone at the lower edge of the windshield is replaced by a reflector mirror as a reflective assembly which can reflect the image rays to the eyes of a viewer in order to achieve a similar or better demonstration effect than a curved panoramic display and to find extensive application in various vehicle models.

[0007] To solve the problem, an embodiment of the panoramic head-up display is provided, which is suitable for installation on a dashboard and comprises the following: a reflector mirror mounted on an upper surface of the dashboard and between the left and right edges of the dashboard, wherein the front surface of the reflector mirror facing the viewer forms an angle of less than 90 degrees with the upper surface of the dashboard; a mirror base attached to the dashboard for fixing the reflector mirror to the dashboard; a transparent protective cap attached to a side of the reflector mirror adjacent to the viewer, wherein the upper edge of the transparent protective cap is connected to the mirror base, while the lower edge is attached to the dashboard for supporting the mirror base; and several flat display modules mounted below the reflector mirror.to project the image rays from each flat display module onto the reflector mirror and then reflect them back via the reflector mirror to the viewer's eyes. This creates multiple virtual images behind the reflector mirror.

[0008] This arrangement of the panoramic head-up display can reduce manufacturing costs and is well suited for installation in various vehicles.

[0009] The reflector mirror can also include several adjacent reflective components.

[0010] The back side of the reflector mirror, opposite the front surface, can also be formed with a dark light-absorbing layer.

[0011] Furthermore, the refractive index of the dark light-absorbing layer can remain analogous to or equal to the refractive index of the reflector mirror material with respect to the image ray.

[0012] The material color of the reflector mirror can also be dark.

[0013] The dark light-absorbing layer can also be made of black, dark blue, dark green, or other dark colors.

[0014] The front surface of the reflector mirror can also be designed as a curved surface.

[0015] The reflector mirror can also be made of a material that can partially reflect the penetrating light.

[0016] Furthermore, the front surface of the reflector mirror can have a reflectivity of less than 40% towards the image beam.

[0017] The front surface of the reflector mirror can further be provided with a low-reflection coating whose reflectivity to the image beam is less than 40%. The material of the reflector mirror can optionally have a refractive index of 1.4 to 1.9 with respect to visible light, where the angle of incidence of the image beam before the front surface of the reflector mirror is greater than 0 degrees and less than 70 degrees.

[0018] The mirror base can also be opaque with a frosted outer surface.

[0019] Furthermore, the material (such as clear glass or plastic) of the transparent protective cap can be penetrated by most image rays (such as > 80%).

[0020] The transparent protective cap can also include several transparent components.

[0021] Each flat display module can also be installed in a recess in the dashboard.

[0022] Furthermore, the display surface can form an angle of greater than or equal to 0 degrees and less than 10 degrees to the horizontal plane of the flat display module.

[0023] The flat display module can further comprise a flat display field and a directional backlight module, wherein the flat display field serves to reproduce an image, while the directional backlight module comprises a backlight array for projecting a directional backlight beam, the directional backlight beam penetrating the flat display field to shape the image beam.

[0024] Furthermore, the lateral diffusion angle of the directional background light beam can be larger than the longitudinal diffusion angle.

[0025] Furthermore, the lateral diffusion angle of the directional background light beam can be more than three times larger than the longitudinal diffusion angle.

[0026] The position of the directional backlight module can also be adjustable.

[0027] Furthermore, the position of the directional backlight module and the position of the flat display field can be adjusted simultaneously relative to each other.

[0028] Furthermore, the flat display fields of all flat display modules can be designed to be spaced apart from each other.

[0029] Furthermore, the flat display fields of all flat display modules cannot be designed to be parallel or aligned with each other. [Drawing description]

[Detailed description of preferred embodiments]

[0031] As from Fig. 4A to Fig. As can be seen in Figure 7F, the panoramic head-up display according to the invention comprises a reflector mirror 1 and several flat display modules 3 (e.g. three flat display modules 3) to solve the problem regarding the projection angle due to the smaller angle between the windscreen 6 and the dashboard ID.

[0032] With reference to Fig. 4A and Fig. 4B The reflector mirror 1 is mounted on the dashboard ID, the angle of the reflector mirror 1 to the horizontal plane being individually adjustable depending on the car model. The angle θm between the front surface 11 of the reflector mirror 1 facing the viewer and the upper surface of the dashboard ID is between 0 and 90 degrees, with the reflector mirror 1 being positioned between the left and right edges of the dashboard ID (for example, between the left and right edges of the dashboard ID, which corresponds to the distance from L-AP of the left A-pillar to R-AP of the right A-pillar of the vehicle).

[0033] The flat display modules 3 are mounted below the reflector mirror 1 and below the mirror base 4 (su) to each project an image beam D onto the reflector mirror 1 and then reflect it via the reflector mirror 1 to the eyes E of a viewer. This creates several virtual images VI behind the reflector mirror 1, which can provide the desired information about the vehicle status, navigation, and other data (including entertainment and audiovisual information).

[0034] A mirror base 4 is attached to the rear of the reflector mirror 1 and is connected to the instrument panel ID. Specifically, the reflector mirror 1 is positioned on an inner surface of the mirror base 4 opposite an outer surface of the mirror base 4. This allows the reflector mirror 1 to be mounted on the instrument panel ID without interfering with the projection path of the image beam D.

[0035] The material of the mirror base 4 is an opaque material with a mattifying outer surface 41 facing the front glass 6 in order to exclude any reflection of an external light beam from the mirror base 4 onto the front glass 6 and to exclude any possible impairment of the view to the front.

[0036] Furthermore, a transparent protective cap 5 is attached to the side of the reflector mirror 1 adjacent to the viewer. Its upper edge is connected to the mirror base 4, and its lower edge is attached to the dashboard ID to provide secure support for the mirror base 4 and prevent potential damage to the structure from external weight. The transparent protective cap 5 thus extends between the left and right edges of the dashboard ID. The material (such as transparent glass or plastic) of the transparent protective cap 5 is permeable to the image ray D, allowing the image ray D to pass through the transparent protective cap 5 and then be projected to the viewer's eyes. This provides protection against interference with the projection path due to the ingress of any foreign objects into the reflector mirror 1.

[0037] The transparent protective cap 5 has a similar or greater width relative to the reflector mirror 1. Specifically, the dimensions of the transparent protective cap 5 are sufficient if the reflector mirror 1 can be completely covered.

[0038] The transparent protective cap 5 can consist of a single transparent component or of several transparent components with a smaller surface area. The embodiment according to the invention is not limited to the number of transparent components and the spacing between them, provided that the mirror base 4 is well supported.

[0039] In this context, the panoramic head-up display according to the invention can achieve a similar or better demonstration effect compared to the conventional panoramic display, but at a lower cost and with more flexible application possibilities compared to the conventionally used curved display field. Furthermore, the panoramic head-up display according to the invention, with its own reflector mirror 1, is not limited to the angles of the windshield 6 of a car and can replace the costly curved display field.

[0040] In this embodiment, the reflector mirror 1 consists of a single reflective component with reference to Fig. 4C. However, the embodiment according to the invention is not limited thereto. In a further embodiment, the reflector mirror 1 can be made up of several small-area, interconnected reflective components RM with reference to Fig. 4D exists to facilitate manufacturing, increase the success rate, and save costs.

[0041] Furthermore, stray light can occur and image quality can be impaired if sunlight or other light rays fall on the dashboard ID and are then reflected by the dashboard ID onto the reflector mirror 1 and subsequently by the reflector mirror 1 to the viewer's eyes E (see Fig. 5A). To solve this problem, the reflector mirror 1, in the present or further embodiment, can be made of a transparent material such as glass or plastic, which is partially permeable to the image ray D. The reflector mirror 1 can absorb the portion of the image ray D that passes through the front surface 11. Furthermore, the front surface 11 of the reflector mirror 1 can be processed and the angle of incidence of the image ray D can be designed such that the reflector mirror 1 has a reflectance relative to the image ray D of, for example, less than 40%.

[0042] As from Fig. As can be seen in Figure 5B, the refractive index of commercially available optical glass in the wavelength range of visible light is between 1.4 and 1.9. For example, in the case of mirror glass with a refractive index of 1.5 of visible light, the total sum of the reflectance Rp of the P-wave plus the reflectance Rs of the S-wave is < 40% when the angle of incidence θi < 70 degrees.

[0043] The reflectivity depends on the surface treatment of the mirror glass and the angle of incidence of the light. For example, a film or coating with lower reflectivity can be applied to the front surface 11, or the angle of incidence θi can be set to, for example, 65 degrees without altering the original material of the reflector mirror 1, so that only 40% or less than 40% of the image beam D from each flat display module 3 is reflected by the reflector mirror 1. Furthermore, the brightness of the backlight source of the flat display module 3 can be increased; for example, the brightness of the projected image beam D from the flat display module 3 can be increased to 1000 cd / m². 2 The brightness of the image beam D after reflection from the reflector mirror 1 must be adjusted so that it is less than 400 cd / m². 2The angle decreases. As a result, the viewer can only see a projected image from the flat display module 3 without the backlighting on the dashboard ID.

[0044] In the present or further embodiment, the front surface 11 of the reflector mirror 1 can be a curved surface, such as a toroidal, double curved surface or free curved surface.

[0045] As from Fig. As can be seen in Figure 5A, part of the image ray D, after passing through the front surface 11 of the reflector mirror 1, becomes an image ray D_2, which, after reflection from the rear surface 12 of the reflector mirror 1, partially becomes an image ray D_3, which, after further passing through the front surface 11 of the reflector mirror 1, partially becomes an image ray D_4. The image ray D_4 is then projected towards the viewer's eyes, resulting in unwanted ghost images.

[0046] Ghost images can impair the image quality being viewed. In this context, the rear surface 12 of the reflector mirror 1, in the present or further embodiment, can be formed with a dark light-absorbing layer 13, for example, black, dark blue, dark green, or another dark color. The material of this dark light-absorbing layer 13 has the same or a similar refractive index with respect to the wavelength of the image beam as the material of the reflector mirror 1. The image beam D_2, penetrating the front surface 11 of the reflector mirror 1, will reach the interface between the rear surface 12 and the dark light-absorbing layer 13 of the reflector mirror 1.Since the refractive index of the reflector mirror 1 is the same or similar to that of the dark light-absorbing layer 13, most of the light rays are absorbed by the dark light-absorbing layer 13, while only a small portion of the light rays is reflected to form an image ray D_3. A small portion of the formed image rays D_3 also penetrates the front surface 11 and thus becomes an image ray D_4. This can significantly weaken image ray D_4, which can lead to a ghost image.

[0047] In the present or further embodiment, the reflector mirror 1 can, for example, consist of black, dark blue, or dark green glass or plastic, in addition to commercially available transparent glass or plastic. This can increase the absorption rate of the image ray D_2 penetrating the front surface 11 of the reflector mirror 1, as well as of the image ray D_3, and significantly weaken or reduce the image ray D_4, which can lead to a ghost image.

[0048] If the reflector mirror 1, which consists of a dark material, has a sufficient absorption rate relative to the image ray D_2 and the image ray D_3, a dark light-absorbing layer 13 on the back surface 12 of the reflector mirror 1 can be omitted, while the exclusion of ghost images is always present.

[0049] In the present or further embodiment, the upper surface of the dashboard ID below the reflector mirror has a recess ID_rc with reference to Fig. 6A designed so that the above-mentioned flat display modules 3, for example three flat display modules 3, can be inserted in the recess ID_rc (see Fig. 6B).

[0050] In the present or further embodiment, each flat display module 3 can consist of, for example, a flat display field 31 and a directional backlight module 32.

[0051] Each flat display panel 31 can display an image. Each directional backlight module 32 comprises an LED array (namely, a backlight array) of several LEDs 321 and can project a directional backlight beam. The projected directional backlight beam can penetrate the flat display panel 31 and project an image beam D with respect to Fig. 4A is formed, which is then projected onto the reflector mirror 1 and subsequently reflected via the reflector mirror 1 to the viewer's eyes. This allows the viewer to see virtual images VI behind the reflector mirror 1.

[0052] The positions of the virtual images VI are similar to those of a conventional curved display field. With the concave front surface 11 of the reflector mirror 1, it is possible to integrate a small flat display field 31 by enlarging the virtual image VI or increasing the distance of the virtual image VI from the viewer. This allows for a similar or greater long-range demonstration effect compared to a conventional curved display field.

[0053] In the present or further embodiment, the individual flat display fields 31 of the several flat display modules 3 can be configured with reference to Fig. 6C, for example, but without being limited thereto, may be spaced apart from each other or not connected to each other, and / or not parallel or aligned to each other, provided that the viewer can see the images projected from each flat display field 31 via the reflector mirror 1.

[0054] In the present or further embodiment, the flat display fields 31 of the flat display modules 3 are designed approximately horizontally, with the display area 311 of each flat display field 31 forming an angle between 0 and 10 degrees to the horizontal plane. This avoids an excessively large angle and makes the flat display field 31 easier for the viewer to see (see Fig. 6D). With reference to Fig. 6E allows the depth of the recess ID_rc to be reduced.

[0055] When images are simultaneously displayed by several flat display modules 3, the viewer can see the clear panoramic image extending from the left to the right side of the dashboard ID, without the backlighting from the dashboard ID and also without the gaps between adjacent flat display fields 31, provided that a dark light-absorbing layer 13 and / or a reflector mirror 1 made of a dark material is used and, in addition, the backlight brightness is increased at the front surface 11 with lower reflectivity. As a result, the viewer is not aware that the virtual images are being projected from several flat display fields 31.

[0056] Furthermore, the scattering angle of the light beam is normally specified as a full width at half maximum (FWHM), so that the angular intensity corresponds to half the maximum intensity value.

[0057] In the present or further embodiment, the directional backlight module 32 is rectangular, with the direction of its longer side defined as transverse and its shorter side as longitudinal. The directional backlight beam emitted by the directional backlight module 32 is wider in the transverse direction and narrower in the longitudinal direction, so that the projected image beam D widens in the transverse direction of the viewer's eyes and narrows in the longitudinal direction. This utilizes the area between the driver and the front passenger, allowing a bright image to be displayed over a wide area of ​​the flat display field 31, resulting in energy savings and reduced cooling.

[0058] As from Fig. As can be seen in Figure 7A, each LED 321 forming the directional backlight module 32 can project a backlight bleed BL. With reference to Fig. 7B and Fig. 7C, the lateral diffusion angle a of the backlight BL is greater than the longitudinal diffusion angle b. To meet the need for a wider viewing angle for a projection between the driver and passenger, a wider lateral beam should be used. To increase the light output and achieve energy savings and cooling, the longitudinal beam should be narrow. For example, the backlight BL can be set to the condition a > 3b.

[0059] As from Fig. As can be seen in Figure 7D, the directional backlight module 32 can project a directional backlight beam L. With reference to Fig. 7E and Fig. 7F, where the lateral diffusion angle A of the background light beam L is greater than the longitudinal diffusion angle B. To meet the need for a wider viewing angle for a projection between the driver and passenger, a wider lateral beam should be used. To increase the light output and achieve energy savings and cooling, the longitudinal beam should be narrow. For example, the background light beam L can be set to the condition A > 3B.

[0060] Furthermore, how from Fig. 8A to Fig. As can be seen in Figure 9C, the panoramic head-up display according to the invention can also adjust the projection angle of the image beam D depending on the position of the viewer's eyes in order to direct the projection angle vertically so that the image beam D is projected onto different heights of the viewer's eyes E1, E2 or E3.

[0061] The following example illustrates how the projection angle is adjusted to different eye positions. <Erste Ausführung>

[0062] As from Fig. 8A to Fig. As can be seen in Figure 8C, the flat display field 31 remains stationary, while the directional backlight module 32 is connected to a swivel drive (not shown), which is connected to a control unit (not shown), the control unit being connected to an eye position sensor (not shown).

[0063] When the eye position sensor detects a change in the viewer's eyes along the longitudinal direction, the control unit, depending on the measurement result of the eye position sensor, causes the pivoting drive to pivot the directional backlight module 32 in order to change the angle of the directional backlight module 32 relative to the flat display field 31 accordingly (see Fig. 8A to Fig. 8C).

[0064] The angle of the display surface 311 of the flat display field 31 to the horizontal plane can be selected to be between 0 and 10 degrees. <Zweite Ausführung>

[0065] As from Fig. 9A to Fig. As can be seen in Figure 9C, the housing of the flat display module 3 is connected to a swivel drive (not shown), which is connected to a control unit (not shown), the control unit being connected to an eye position sensor (not shown).

[0066] When the eye position sensor detects a change in the viewer's eyes along the longitudinal direction, the control unit, depending on the measurement result of the eye position sensor, causes the pivoting drive to pivot the flat display module 3 so that the directional backlight module 32 and the flat display field 31 change their positions simultaneously in order to change the angle of the display surface 311 relative to the horizontal plane accordingly (see Fig. 9A to Fig. 9C).

[0067] The angle of the display surface 311 of the flat display field 31 to the horizontal plane can be selected to be between 0 and 10 degrees.

[0068] In this type of panoramic head-up display, the reflector mirror is positioned between the left and right edges of the dashboard and is also equipped with a mirror base attached to the dashboard behind the reflector mirror and a transparent protective cap for support in front of the reflector mirror. The reflective surface of the reflector mirror has a low reflectivity, so that the reflector mirror does not reflect light from the dashboard and can still absorb the light penetrating the reflective surface of the reflector mirror in order to exclude any ghost images.Furthermore, several flat display modules are mounted on the dashboard below the reflector mirror. Each flat display module projects an image beam onto the reflector mirror, which is then reflected back to the viewer's eyes, allowing the viewer to see the virtual images across the field of vision between the left and right sides of the dashboard. This allows it to be adjusted to the windshield angles of different vehicles, achieving a similar or better display effect than a conventional, expensive, curved panoramic display.

[0069] The embodiment according to the invention is not limited to the exemplary embodiments, but can be varied in many ways within the scope of the disclosure. In this context, all new individual and combination features disclosed in the description and / or drawings are considered essential to the invention.
