CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is the U.S. national stage of International
Application No. PCT/EP2018/053760, filed Feb. 15, 2018, and claims
the benefit thereof. The International Application claims the
benefit of German Application No. 10 2017 203 167.0 filed on Feb.
27, 2017, both applications are incorporated by reference herein in
their entirety.
BACKGROUND
[0002] Described below is a display device for an inner wall of an
interior of a vehicle and to a method for presenting display
content in an interior of a vehicle.
[0003] A display or a display panel usually has a defined emission
angle. So-called dual-view displays, in which different images are
visible from two different directions, are also known. However, it
should be taken into account in this respect that these dual-view
displays present a respective image or partial image only with half
the resolution of the overall display on account of their
properties.
[0004] A foldable display device is known from the document US
2012/0235894 A1. In this case, this display device includes two
display panels which are connected to one another and can be
positioned at an angle relative to one another along a common axis.
During operation of this display system, partial displays of the
display elements are combined in an angle-dependent manner to form
a common display.
[0005] A display device and a method for operating the latter are
described in the document EP 2 902 870 A2. This display device also
includes two display elements which can be positioned at an angle
relative to one another, wherein display content of these two
displays is merged in an angle-dependent manner to form a common
display content.
[0006] The document DE 20 2004 012 734 A1 furthermore shows a flat
screen which is composed of pixels, wherein its image area is
divided into at least two zones, wherein one zone is provided with
an applied emission filter which emits in different directions for
each pixel.
[0007] Against this background, the display device in a vehicle
presents display content in the manner described below.
[0008] The display device can be arranged and/or is to be arranged
on an inner wall in an interior of a vehicle and is subdivided into
a plurality of display panels. In this case, two directly adjacent
display panels are respectively connected to one another along a
common axis, for example a bending axis, wherein these two directly
adjacent display panels can be pivoted relative to one another
about the common axis. The display device has at least one bending
plane, wherein at least one display panel can also be pivoted
relative to the at least one bending plane, wherein an angle
.alpha. can be set and/or has been set for this at least one
display panel which can be pivoted relative to the at least one
bending plane, at which angle this at least one display panel which
can be pivoted relative to the at least one bending plane emits
display content into the interior, for example in the clockwise or
anti-clockwise direction depending on the definition, relative to
the at least one bending plane if a surface of this at least one
display panel which can be pivoted relative to the at least one
bending plane is oriented perpendicular to the at least one bending
plane, for example, depending on the definition, in a first
operating position. This at least one display panel which can be
pivoted relative to the at least one bending plane is pivoted at an
angle of 90.degree.-.alpha., in the clockwise or anticlockwise
direction depending on the definition, relative to the at least one
bending plane in a second operating position.
[0009] In this case, this at least one display panel which can be
pivoted relative to the bending plane emits the display content
into the interior parallel to the at least one bending plane in the
second operating position. In one configuration, an axis, about
which two directly adjacent display panels can be pivoted relative
to one another, runs through the at least one bending plane,
relative to which the at least one display panel can be pivoted and
to which the display panel is assigned.
[0010] In the case of the display device, provision is made, for
example, for its at least one bending plane to be able to be
oriented and/or to have to be oriented at a respectively provided
angle, generally perpendicular, with respect to a surface of the
inner wall. If the display device has a plurality of pivotable
display panels, they are assigned to the at least one bending
plane. In this case, it is possible for each display panel to be
assigned to its own bending plane. It is accordingly possible for
at least one bending plane to be assigned to at least one pivotable
display panel.
[0011] It is also possible for the angle .alpha. provided for the
at least one display panel which can be pivoted relative to the at
least one bending plane to be an acute angle and therefore greater
than -90.degree. and less than +90.degree.. In this case, depending
on the definition, for example on the basis of the clockwise
direction, it is possible for a respective angle .alpha. which is
provided for a respective pivotable display panel to have a
positive value or a negative value.
[0012] In one configuration, the display device has at least one
pair of display panels which can both be pivoted relative to the at
least one bending plane, that is to say only one bending plane or
one bending plane each, and can be correlated and/or are correlated
with one another. In this case, surfaces of both display panels are
oriented perpendicular to the at least one bending plane in the
first operating position, wherein the two display panels emit a
respective display content at a respective angle .alpha. relative
to the at least one bending plane and at an angle of
90.degree.-.alpha. relative to their own surface, wherein,
depending on the definition, for example taking into account the
clockwise direction, the angle .alpha. for a first of the two
display panels has a positive or negative value and, depending on
the definition, for example taking into account the clockwise
direction, the angle for a second of the two display panels has a
negative or positive value, wherein the two display panels emit the
display contents in different directions which are oriented at
twice the angle .alpha. or at an angle of 2.alpha., with a positive
or negative value depending on the definition, with respect to one
another.
[0013] The surface of the first of the two display panels is
pivoted at an angle of 90.degree.-.alpha., with a positive or
negative value depending on the definition, relative to the at
least one bending plane in the second operating position, wherein
the surface of the second of the two display panels is pivoted at
an angle of 90.degree.-.alpha., with a negative or positive value
depending on the definition, relative to the at least one bending
plane in the second operating position, wherein the two display
panels emit the display contents parallel to one another in the
second operating position.
[0014] In this respect, it is also possible for the at least one
bending plane to be arranged between the two display panels of the
at least one pair of display panels, wherein the two display panels
emit the display content away from the at least one bending plane
in each case in the first operating position.
[0015] Depending on a perspective, it is also possible for the
first display panel to be arranged to the left or right of the at
least one bending plane and for the second display panel to be
accordingly arranged to the right or left of the at least one
bending plane depending on the definition. In this case, the first
display panel to the left or right of the at least one bending
plane emits the display content to the left or right away from the
at least one bending plane in the first operating position and the
second display panel to the right or left of the at least one
bending plane emits the display content to the right or left away
from the at least one bending plane in the first operating
position.
[0016] One configuration provides for the angle .alpha. for the at
least one display panel to be usually permanently set for both
operating positions. Accordingly, the angle 90.degree.-.alpha., at
which the display content of a respective pivotable display panel
is emitted, is permanently set for both operating positions and is
constant. However, it is also possible for the angle .alpha. to
also be able to be varied and to be able to be set depending on
requirements. Therefore, a value which is suitable and/or desired
for at least one user of the display device can be permanently set
and stored for the angle .alpha..
[0017] It is additionally possible for the display device to have
at least one further display panel which is arranged and/or fixed
in a stationary manner relative to the at least one bending plane
and can be fixed in a stationary manner relative to the inner wall,
wherein a surface of this at least one fixed display panel is
oriented perpendicular to the at least one bending plane, wherein
this at least one fixed display panel emits the display content
parallel to the at least one bending plane in both operating
positions and therefore independently of a respective operating
position of the at least one pivotable display panel. The display
content of at least one pivotable display panel is oriented at the
angle .alpha. relative to the display content of the at least one
fixed display panel in the first operating position, whereas
display contents of the at least one pivotable display panel and of
the at least one fixed display panel are oriented parallel to one
another in the second operating position.
[0018] It is therefore also possible for the display device to have
at least one pair of display panels which can be pivoted relative
to the at least one bending plane and can be correlated and/or are
correlated with one another and at least one display panel which is
fixed relative to the at least one bending plane, wherein the at
least one display panel which is fixed relative to the at least one
bending plane is generally arranged between the two display panels
of the at least one pair which can be pivoted relative to the at
least one bending plane.
[0019] In one configuration, the display device includes at least
one holding device having two outer surfaces arranged parallel to
one another, wherein a first of the two outer surfaces is connected
to at least one of the display panels, wherein a second of the two
outer surfaces can be fastened and/or is to be fastened to the
inner wall.
[0020] The display device can usually be arranged and/or is to be
arranged between two seats of the vehicle on an inner wall of the
interior of the vehicle which is arranged at the front in a forward
direction of travel of the vehicle, wherein the at least one
display panel which can be pivoted relative to the at least one
bending plane emits the display content in the direction of one of
the two seats in the first operating position. If the display
device has at least one pair of pivotable display panels which are
correlated with one another, one display panel respectively emits a
respective display content to the interior of the vehicle in the
direction of one seat in each case.
SUMMARY
[0021] The method is provided for the purpose of presenting at
least one display content in an interior of a vehicle using a
display device which is arranged on an inner wall in an interior of
a vehicle and is subdivided into a plurality of display panels,
wherein two directly adjacent display panels are connected to one
another along a common axis, for example a bending axis, wherein
these two directly adjacent display panels can be pivoted relative
to one another about the common axis. The display device has at
least one bending plane, wherein at least one display panel is
assigned to this at least one bending plane and can also be pivoted
relative to the at least one bending plane, wherein an angle
.alpha. is set for this at least one display panel which can be
pivoted relative to the at least one bending plane, at which angle
display content of this at least one display panel which can be
pivoted relative to the at least one bending plane is emitted into
the interior, in the clockwise or anti-clockwise direction
depending on the definition, relative to the at least one bending
plane if a surface of this at least one display panel which can be
pivoted relative to the at least one bending plane is oriented
perpendicular to the at least one bending plane in a first
operating position. This at least one display panel which can be
pivoted relative to the at least one bending plane is pivoted at an
angle of 90.degree.-.alpha., in the clockwise or anti-clockwise
direction depending on the definition, relative to the at least one
bending plane in a second operating position, wherein the display
content of this at least one display panel which can be pivoted
relative to the bending plane is emitted parallel to the at least
one bending plane in the second operating position. In both
operating positions mentioned, the display content of the at least
one pivotable display panel is respectively emitted at an angle of
90.degree.-.alpha. relative to the surface thereof.
[0022] Overall, the presented display device is flexible, wherein
display content or display contents is/are emitted at different
angles in the first operating position and is/are emitted into the
interior of the vehicle at the same angle in the second operating
position using the display panels or displays of the device.
[0023] In this case, the display device is subdivided into at least
two display panels and therefore into two viewing areas. In this
case, each display panel is assigned its own specific emission
angle and therefore angle .alpha., for example by a special light
control film, wherein this angle .alpha. is set taking into account
the clockwise direction depending on the position of at least one
pivotable display panel relative to the at least one bending plane.
In this case, it is possible for this angle to have a positive or
negative value depending on the definition and taking into account
the clockwise direction. On account of flexibility of the display
device, it is possible to bend a junction between two directly
adjacent display panels or displays or viewing areas, for example
using kinematics integrated in the common axis and/or the holding
device, for example. It is therefore possible, inter alia, to
manipulate the emission direction of the angle of a pivotable
display panel. If an embodiment of the display device is used when
carrying out an embodiment of the method, different possible ways
of viewing the display content which can be presented therewith can
be achieved depending on an orientation of a respective display
panel.
[0024] It goes without saying that the features mentioned above and
the features yet to be explained below can be used not only in the
respectively stated combination but also in other combinations or
along without departing from the scope of the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0025] These and other aspects and advantages will become more
apparent and more readily appreciated from the following
description of exemplary embodiments described in detail and
schematically with reference to the drawings of which:
[0026] FIG. 1 is a schematic illustration of a first embodiment of
the display device in different operating states which result when
carrying out a first embodiment of the method.
[0027] FIG. 2 is a schematic illustration of a second embodiment of
the display device in different operating states which result when
carrying out a second embodiment of the method.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0028] The figures are described in a connected and comprehensive
manner and the same reference signs are assigned to identical
components.
[0029] The first embodiment of the display device 2 is
schematically illustrated in a first operating position in FIG. 1a
and in a second operating position in FIG. 1b. This display device
2 has a first display panel 4 and a second display panel 6 in this
case. A bending plane 8 is also defined in the display device 2
and, in the first operating position (FIG. 1a), is oriented
perpendicular to the surfaces of both display panels 4, 6, wherein
the surfaces of both display panels 4, 6, in the first operating
position, are arranged parallel to one another and beside one
another in a common plane which is likewise oriented perpendicular
to the bending plane 8. In this case, these two display panels 4, 6
form a pair of display panels 4, 6 which are arranged symmetrically
with respect to the bending plane 8 and can be pivoted in opposite
directions relative to the bending plane 8, wherein a common axis,
about which these display panels 4, 6 which are directly adjacent
here can be pivoted, runs through the bending plane 8.
[0030] In this case, the display device 2 also has a holding device
10 having a first outer surface or outer side to which the two
display panels 4, 6 are pivotably fastened. The holding device 10
also has a second outer surface or outer side, via which the
holding device 10 and therefore also the entire display device 2
can be arranged on an inner wall of a vehicle, for example on a
center console between two front seats of the vehicle.
[0031] In the first operating position, provision is made for
display content 12 of the first display panel 4, which is arranged
here to the left of the bending plane 8, to be emitted to the left
at an angle .alpha. which here is pivoted to the left from the
display plane 8 in the clockwise direction. Accordingly, the first
display content 12 is emitted to the left at an angle of
90.degree.-.alpha. relative to a surface of the first display panel
4. In contrast, second display content 14 of the second display
panel 6 is likewise emitted at the angle .alpha. which, however, is
pivoted here to the right from the bending plane 8 in the
anti-clockwise direction. Accordingly, the second display content
14 is emitted to the right at an angle of 90.degree.-.alpha.
relative to a surface of the second display panel 6. Therefore, the
first display content 12 is visible from a first perspective in the
first operating position and the second display content 14 is
visible from a second perspective in the first operating position,
wherein directions of these two display contents 12, 14 are overall
oriented at twice the angle .alpha. or at an angle 2.alpha.
relative to one another.
[0032] In the second operating position provided on the basis of
FIG. 1b, provision is made for the first display panel 4 arranged
on the left to be pivoted to the right in the anti-clockwise
direction toward the bending plane 8 at an angle of
90.degree.-.alpha., whereas the right-hand, second display panel 6
is pivoted to the left in the clockwise direction toward the
bending plane 8 likewise at the angle of 90.degree.-.alpha..
[0033] However, provision is made for a respective angle
90.degree.-.alpha., at which display content 12, 14 of a respective
display panel 4, 6 is emitted relative to a respective surface of
the respective display panel 4, 6 with respect to the first
operating position, to also be retained in the second operating
position, thus resulting in the display contents 12, 14 of both
display panels 4, 6 being emitted parallel to one another and also
parallel to the bending plane 8 in the second operating
position.
[0034] The second embodiment of the display device 40 is
schematically illustrated in a first operating position in FIG. 2a
and in a second operating position in FIG. 2b. This display device
40 here includes a first display panel 13, a second display panel
16 and a third, fixed display panel 30 which is arranged between
the first and second display panels 13, 16. Furthermore, a first
bending plane 15, which is assigned to the first display panel 13,
and a second bending plane 17, which is assigned to the second
display panel 16, are defined for the display device 40.
[0035] In this case, a first axis, about which the first display
panel 13 can be pivoted relative to the directly adjacent third
display panel 30, runs through the first bending plane 15. The
second display panel 16 can be pivoted relative to the directly
adjacent third display panel 30 about a second axis which runs
through the second bending plane 17. The two bending planes 15, 17
which are parallel to one another are oriented perpendicular to the
surfaces of all three display panels 13, 16, 30 in the first
operating position (FIG. 2a), wherein the surfaces of the display
panels 13, 16, 30, in the first operating position, are arranged
parallel to one another and beside one another in a common plane
which is likewise oriented perpendicular to the bending planes 15,
17 which are parallel to one another.
[0036] The display device 40 also here includes a holding device 20
having a first outer surface to which the third display panel 30 is
fastened in a stationary manner and is therefore fixed. The holding
device 20 also has a second outer surface, via which the holding
device 20 and therefore also the entire display device 40 can be
arranged on an inner wall of a vehicle, for example on a center
console between two front seats of the vehicle. The first outer
surface and the second outer surface of the holding device 20,
which is parallel to the first outer surface, are oriented
perpendicular to the two bending planes 15, 17. The first display
panel 13 can be pivoted relative to the first bending plane 15
assigned to it, the third display panel 30 and the holding device
20 and therefore also the inner wall. In addition, the second
display panel 16 can be pivoted relative to the second bending
plane 17 assigned to it, the third display panel 30 and the holding
device 20 and therefore also the inner wall.
[0037] In the first operating position, provision is made for
display content 22 of the first display panel 13, which is arranged
here to the left of the first bending plane 8 and the third display
panel 30, to be emitted to the left at an angle .alpha. which is
here pivoted to the left in the clockwise direction from the
display plane 8. Accordingly, the first display content 22 is
emitted to the left at an angle of 90.degree.-.alpha. relative to a
surface of the first display panel 13. In contrast, second display
content 24 of the second display panel 16 is likewise emitted at
the angle .alpha. which, however, is here pivoted to the right in
the anti-clockwise direction from the second bending plane 8 and
the third display panel 30. Accordingly, the second display content
24 is emitted to the right at an angle of 90.degree.-.alpha.
relative to a surface of the second display panel 16. Display
content 32 of the third display panel 30 is emitted parallel to the
bending planes 15, 17 and perpendicular to the surface thereof in
the first operating position. The first display content 22 is
therefore visible from a first perspective in the first operating
position and the second display content 24 is visible from a second
perspective in the first operating position, wherein directions of
these two display contents 22, 24 are overall oriented at an angle
with respect to one another which is twice as large as the angle
.alpha., that is to say at an angle 2.alpha. or 2*.alpha..
[0038] In the second operating position provided on the basis of
FIG. 2b, provision is made for the first display panel 13 which is
arranged on the left to be pivoted to the right in the
anti-clockwise direction toward the first bending plane 15 and the
third display panel 30 at an angle of 90.degree.-.alpha., whereas
the right-hand second display panel 16 is pivoted to the left in
the clockwise direction toward the second bending plane 17 and the
third display panel 30 likewise at the angle of 90.degree.-.alpha..
In contrast, an orientation of the third display panel 30 and its
display content 32 relative to the holding device 20 and therefore
the inner wall is unchanged in the second operating position in
comparison with the first operating position.
[0039] However, provision is made for a respective angle
90.degree.-.alpha., at which the display content 22, 24 of the
first and second display panels 13, 16 is emitted relative to a
respective surface of the respective display panel 13, 16 with
respect to the first operating position, to also be retained in the
second operating position, thus resulting in the display contents
22, 24, 32 of all three display panels 13, 16, 30 being emitted
parallel to one another in the second operating position. In the
second embodiment, the first and second display panels 13, 16 form
a pair of display panels 13, 16 which are arranged symmetrically
with respect to the fixed, third display panel 30 arranged between
them and can be pivoted in opposite directions with respect
thereto.
[0040] A description has been provided with particular reference to
preferred embodiments thereof and examples, but it will be
understood that variations and modifications can be effected within
the spirit and scope of the claims which may include the phrase "at
least one of A, B and C" as an alternative expression that means
one or more of A, B and C may be used, contrary to the holding in
Superguide v. DIRECTV, 358 F3d 870, 69 USPQ2d 1865 (Fed. Cir.
2004).
