[0022] Reference will be made to Figures 1 to 6 describe a "vehicle display device" according to an embodiment of the present invention.

[0023] As Figure 1 shown, the vehicle display device 1 includes: a display panel 2 and linear illuminations 4, 5 provided at the instrument panel 9 of an automobile; a linear illumination 6 provided on the inner lining of the driver's side door 11; and a linear illumination 7 provided on the inner lining of the front passenger's side door 12.

[0024] The display panel 2 according to this example is a full-range liquid crystal panel, wherein the display panel 2 serves as an instrument panel, an audio, and an in-vehicle navigation display, and has functions such as displaying entertainment information. The display panel 2 has a plate shape extending in the length direction of the instrument panel 9. The instrument panel 9 has a shape extending in the vehicle width direction. That is, the length direction of the instrument panel 9 is along the vehicle width direction, and the width direction of the instrument panel 9 is along the vehicle height direction.

[0025] The linear illuminations 4 to 7 are configured as illuminations generally referred to as "ambient lights". The linear illumination 4 extends along the length direction of the instrument panel 9 from the right end of the instrument panel 9 towards the display panel 2 when viewed from the driver's side. The linear illumination 5 extends along the length direction of the instrument panel 9 from the left end of the instrument panel 9 towards the display panel 2 when viewed from the driver's side. For the linear illuminations 4 and 5, it is sufficient that they extend along the length direction of the instrument panel 9 near the display panel 2, and the portions of the linear illuminations 4 and 5 away from the display panel 2 do not necessarily extend along the length direction of the instrument panel 9. The linear illumination 6 extends backward from near the right end of the linear illumination 4. The linear illumination 7 extends backward from near the left end of the linear illumination 5.

[0026] As Figure 5 shown, the linear illumination 4 includes a strip-shaped light guide member 41 and a plurality of full-color LEDs 42 arranged along the light guide member 41. The light guide member 41 has a semi-reflective mirror structure with a metal vapor deposition layer 41a (see Figure 6 ), such that the light guide member 41 appears silver when the LED 42 is turned off, and appears as the color of the light emitted from the LED 42 when the LED 42 is turned on. Although the structures of the remaining linear illuminations 5 to 7 are omitted in the figure, they have the same structure as the linear illumination 4. The linear illuminations 4 to 7 are controlled by a control unit (not shown).

[0027] It is sufficient that the display device 1 includes at least one of the linear illuminations 4 and 5 (either the linear illumination 4 or 5), and the linear illuminations 6 and 7 are not necessary. Additional linear illuminations can be provided on the door lining on the rear seat side, and the additional linear illuminations are continuous with the linear illuminations 6 and 7.

[0028] As an example of the display on the display panel 2, the display panel 2 displays Figure 2 , 3A and the linear display portion 3 shown in FIGS. 3A and 3B. The linear display portion 3 includes: a first linear portion 31 that extends along the length direction of the instrument panel 9; a second linear portion 32 that extends upward from the end of the first linear portion 31; a third linear portion 33 that extends along the length direction of the instrument panel 9 from the end of the second linear portion 32; a fourth linear portion 34 that extends downward from the end of the third linear portion 33; and a fifth linear portion 35 that extends along the length direction of the instrument panel 9 from the end of the fourth linear portion 34. The first linear portion 31 is continuous with the end of the linear illumination 4. The fifth linear portion 35 is continuous with the end of the linear illumination 5.

[0029] In Figure 2In this case, the linear display section 3 is displayed in area A, where the linear illuminations 4 and 5 are located in areas B and C respectively. In a state where the linear display section 3 is displayed and the linear illuminations 4 to 7 are turned on, they appear to form a single glowing continuous line extending from the driver's side door 11 through the instrument panel 9 to the passenger side door 12. This line can be monochromatic (the linear illuminations 4 to 7 and the linear display section 3 can emit light of the same color), or multicolored, or a gradient color. In addition, their on / off cycles can be offset from each other so that it looks as if the light is flowing.

[0030] In this way, the linear display section 3 of the display panel 2 and the linear illuminations 4 to 7 can be continuous, thus achieving a cockpit design with a unified sense of horizontal tone. In this example, the shape of the linear display section 3 is similar to the outer shape of the display panel 2 to enhance the sense of unity.

[0031] Specifically, the second linear section 32 extends parallel to the edge 2a at the right end of the display panel 2, and the fourth linear section 34 extends parallel to the edge 2c at the left end of the display panel 2, such that the second linear section 32, the third linear section 33, and the fourth linear section 34 form a trapezoidal shape that is similar to the shape formed by the edges 2a, 2b, and 2c of the display panel, as Figure 3A and 3B shown.

[0032] Furthermore, in order to make the linear display section 3 of the display panel 2 connect more smoothly and seamlessly with the linear illuminations 4 and 5, the ends of the linear illuminations 4 and 5 overlap with the driver's side of the display panel 2, as [[ID=!4]] Figures 4 to 6 shown. Although Figures 4 to 6 only the linear illumination 4 is shown, the linear illumination 5 has the same structure.

[0033] In Figures 4 to 6 reference numeral 91 denotes the cover member of the instrument panel 9, reference numeral 27 denotes the housing of the display panel 2, reference numeral 28 denotes the TFT liquid crystal panel, and reference numeral 29 denotes the cover glass. As Figure 6 shown, the light guide member 41 of the linear illumination 4 gradually approaches the front surface (the side facing the driver) of the cover glass 29 of the display panel 2 in the direction toward the left end of the light guide member 41, where the left end of the light guide member 41 contacts the front surface of the cover glass 29.

[0034] The linear display portion 3 divides the display panel 2 into two areas, namely a first area 21 and a second area 22. The first area 21 is configured to display information necessary for determining driving actions, such as various types of instrument information, car navigation information, and driver assistance information (in the example shown, information for blind spot monitoring). In addition, in this example, the vehicle speed display portion 23 is displayed on the third linear portion 33. In this way, the first to fifth linear portions include interrupted portions. The second area 22 is configured to display information unrelated to driving, such as group icons (friends connected via VV communication) and / or recommendation information from friends.

[0035] The first area 21 and the second area 22 have ranges that change in the left and right directions according to their respective information amounts and / or priorities. For example, during manual driving, the first area 21 is enlarged, as shown in FIG. Figure 2 and Figure 3B This is because a large amount of information is required to determine the driving action. On the other hand, during autonomous driving, as shown in Figure 3A As shown, the first area 21 is reduced (the first and second areas 21, 22 are of similar size) because less information is required to determine the driving maneuver. In this way, the changes in the range of the first and second areas 21, 22 are accompanied by changes in the boundaries between the third and fourth linear portions 33, 34, and between the fourth and fifth linear portions 34, 35. This means that the lengths of the third and fifth linear portions 33, 35 are changed, and the fourth linear portion 34 is displaced in the left-right direction.

[0036] In this example, the information displayed on the display panel 2 is segmented by the linear display portion 3 in the manner described above, thereby facilitating easier identification of the information for the driver. Furthermore, the linear illuminations 4 to 7 and the linear display portion 3 according to this example are synchronized to provide the driver with information that is easier to identify. A specific example of this synchronized illumination will be described below.

[0037] For example, when the car is driving, the linear lighting 4 to 7 and the linear display 3 are set to emit a light blue light during automatic driving. When automatic driving is stopped, the linear lighting 4 to 7 and the linear display 3 are set to emit amber light. During manual driving, the linear lighting 4 to 7 and the linear display 3 are set to emit white light. In this way, the driving status is indicated by the coordinated lighting of the linear lighting 4 to 7 and the linear display 3, allowing the driver to understand the driving status without having to look at a point on the display panel 2, thus avoiding mode confusion.

[0038] When operating the turn signal in the case of right / left turn and / or changing the route, the turn signal indicator (e.g., arrow mark) in the first area 21 blinks green, and a part of the linear display section 3 and the linear illuminations 4 to 7 (e.g., in the case of a right turn, the right part of the third linear section 33, the second linear section 32, the first linear section 31, and the linear illuminations 4 and 6) blink green light with the same cycle length as the turn signal indicator. Their blinking cycles are offset from each other (blinking over time), so it looks as if the green light is flowing. In addition, when an ADAS warning is issued, the linear illuminations 4 to 7 and the linear display section 3 blink amber. By providing information to the driver in this way, the driver can intuitively understand the information without having to gaze at a point on the display panel 2.

[0039] As described above, the display device 1 includes the linear display section 3 that is continuously located in the display panel 2 at the ends of the linear illuminations 4 and 5, where the linear illuminations 4 to 7 and the linear display section 3 are configured to be capable of linked light emission. This means that the linear display section 3 of the display panel 2 is interrelated with the linear illuminations 4 to 7. This enables a cockpit design with a unified sense of horizontal tone to be provided. In addition, the linked light emission of the linear illuminations 4 to 7 and the linear display section 3 enables information to be provided to the driver quickly and in an easily recognizable manner.

[0040] In addition, the display panel 2 in the display device 1 is divided into two areas, namely the first area 21 and the second area 22, by the linear display section 3, which enables information to be presented to the driver in an easily recognizable manner on the display panel 2.

[0041] In addition, the display device 1 is configured such that the linear illuminations 4 and 5 are placed on the left and right sides of the display panel 2, where the first linear section 31 is positioned to be continuous with the end of the linear illumination 4 on one side of the right or left side, and the fifth linear section 35 is positioned to be continuous with the end of the linear illumination 5 on the other side of the right or left side, further enhancing the unified sense of the cockpit.

[0042] In addition, the display device 1 is configured such that the ranges of the first area 21 and the second area 22 are changed according to the amount of information and / or priority of the first area 21 and the second area 22, along with changing the boundary between the third linear section 33 and the fourth linear section 34 and changing the boundary between the fourth linear section 34 and the fifth linear section 35, which enables the information displayed on the display panel 2 to be provided to the driver in an easier-to-recognize manner.

[0043] In addition, the display device 1 is configured such that the linear illuminations 4 to 7 and the linear display section 3 are configured to be capable of emitting light of the same color, which enables the unified sense of the cockpit to be further enhanced. This also enables information to be provided to the driver in an easier-to-recognize manner.

[0044] The display device 1 is also configured such that when viewed from the driver's side, the ends of the linear illuminations 4 and 5 overlap with the display panel 2, enabling the linear display section 3 of the display panel 2 and the linear illuminations 4 and 5 to be connected more smoothly and seamlessly.

[0045] Although according to the above-described embodiment, the ends of the linear illuminations are continuous (connected) with the linear display section, the ends of the linear illuminations may not be continuous with the linear display section, and there may be a gap therebetween. In such a case, it is only necessary to position the linear display section on the extension line of the linear illumination.

[0046] Although the "display panel" according to the above-described embodiment is configured as a liquid crystal panel, the display panel may also be configured by an organic EL panel. In addition, the display panel may be configured as a combination of an analog meter (physical meter) and a two-dimensional display panel (liquid crystal panel / organic EL panel). The display panel does not necessarily have to have a meter function, but it is sufficient for the display panel to have some information display function.

[0047] Although the "linear display section" according to the above-described embodiment is configured as an image displayed on a liquid crystal panel, the linear display section may also be constituted by a physical light-emitting entity like the linear illumination.

[0048] The above-described embodiment is configured such that when the turn signal is operated, the turn signal indicator, the linear display section, and the linear illumination flash with a time offset to present an effect as if green light is flowing. In addition to controlling the direction of the flow, a directional design expression such as ">>>>" may be adopted to provide information to the user in the vehicle without relying on animation.

[0049] Although according to this embodiment, only one layer (one row) of linear illumination is provided in the height direction at each position, three or more layers (three or more rows) of linear illumination may be provided in the height direction, so that in a scene such as a rear view that is difficult to recognize and thus requires attention, not only information about the direction but also information such as distance (height) and / or degree of danger (risk level) can be expressed, which enables various types of information to be provided to the user.

[0050] In addition, the linear illumination can be used as a low-resolution display device combined with the display panel to display information such as a map and / or TbyT by extending it outside the display panel of the display panel. This means that information about an area outside the display area of the display panel, such as a destination icon, can be easily displayed.

[0051] In addition to MET and / or CID, devices such as mirrors are increasingly used in the cockpit. In view of this, they can be used by connecting them to a linear illumination having one row.

[0052] It should be noted that the embodiments described above are only shown as representative examples of the present invention, and the present invention is not limited to these embodiments. That is, various modifications can be made without departing from the core of the present invention. Obviously, as long as these modifications include the features of the present invention, they are also included within the scope of the present invention.
