[0024] The utility model relates to a vehicle-mounted display device, and more particularly to a large-sized vehicle-mounted display device. Figure 2 , Figure 2FIG. 1 is a schematic diagram of an embodiment of a vehicle-mounted display device of the present invention. The vehicle-mounted display device 10 has a display area AA and a peripheral area BA located at the periphery thereof. Figure 2 As shown, the vehicle-mounted display device 10 includes a supporting frame 100, a lamp board 200, an optical film material 300, a display panel assembly 400 and an auxiliary light guide assembly 500. The supporting frame 100 has a bottom plate 110 and a side portion 120 connected thereto, the bottom plate 110 has a first supporting surface 111, the side portion 120 has a first supporting portion 121 and a second supporting portion 122 in a stepped shape, and the first supporting portion 121 is located between the bottom plate 110 and the second supporting portion 122. The lamp board 200 is accommodated in the supporting frame 100 and is arranged on the first supporting surface 111, and a plurality of light sources 201 arranged in an array may be arranged on the lamp board 200. The optical film material 300 is accommodated in the supporting frame 100 and is carried on the first supporting portion 121, and the display panel assembly 400 is fixed on the second supporting portion 122. Further, the display panel assembly 400 includes a display panel 410 and a cover plate 420 that are bonded to each other. For example, the cover plate 420 is bonded to the display panel 410 via an optical adhesive 430. The edge of the cover plate 420 may exceed the edge of the display panel 410, so that the display panel assembly 400 is fixed to the second support portion 122 via the edge of the cover plate 420. The auxiliary light guide assembly 500 is located in the peripheral area BA, and the auxiliary light guide assembly 500 is disposed on a side of the display panel assembly 400 that faces the first support portion 121. Specifically, the auxiliary light guide assembly 500 is disposed on the display panel 410 or the cover plate 420 adjacent to the edge of the display panel 410, and the auxiliary light guide assembly 500 has a spacing with the upper surface of the optical film material 300 carried on the first support portion 121, that is, the auxiliary light guide assembly 500 does not contact the upper surface of the optical film material 300.
[0025] like Figure 2 As shown, the vehicle-mounted display device 10 further includes a foam tape 600, and the display panel 410 assembly 400 is fixedly connected to the second support portion 122 via the foam tape 600.

At this time, the auxiliary light guide component 500 and the upper surface of the at least one brightness enhancement film 320 have the aforementioned spacing. The light emitted by each light source 201 on the light board 200 enters the diffuser plate 310 and the at least one brightness enhancement film 320 to form a uniform surface light source and irradiate the display panel component 400. When the vehicle-mounted display device 10 is assembled, the auxiliary light guide component 500 and the upper surface of the optical film material 300 have a spacing, so that the auxiliary light guide component 500 will neither affect the light transmission of the optical film material 300 itself, nor limit the slight displacement (such as thermal expansion and contraction) that may occur in the optical film material 300 during the application process.
[0026] In the present invention, when the vehicle-mounted display device 10 is in use, the auxiliary light guide assembly 500 can provide light to the first support portion 121, so that the first support portion 121 is brightened, and the user cannot easily see the edge of the optical film material 300, nor the first support portion 121, so that the size of the optical film material 300 in the peripheral area BA can be reduced, and the size of the supporting frame 100 in the peripheral area BA can be reduced accordingly, and the frame size of the vehicle-mounted display device 10 is reduced as a whole. Furthermore, the auxiliary light guide assembly 500 will not contact the optical film material 300, ensuring the normal operation of the optical film material 300 itself.
[0027] like Figure 2 As shown, in this embodiment, the auxiliary light guide component 500 is arranged on the cover plate 420 (the lower surface) adjacent to the edge of the display panel 410, and the auxiliary light guide component 500 includes an auxiliary light source 520 and a light guide column structure 510, the light guide column structure 510 has a light incident surface (not marked) and a light emitting surface (not marked) facing the first support portion 121, and the light emitted by the auxiliary light source 520 enters the light guide column structure 510 from the light incident surface, is transmitted within the light guide column structure 510, and is emitted from the light emitting surface toward the first support portion 121.
[0028] In the present embodiment, when the vehicle-mounted display device 10 is in use, the light emitted by the auxiliary light source 520 is emitted toward the first support portion 121 via the light guide column structure 510, so that the first support portion 121 is brightened, and the user cannot easily see the edge of the optical film material 300 or the first support portion 121, so that the size of the optical film material 300 in the peripheral area BA can be reduced, and the size of the supporting frame 100 in the peripheral area BA can also be reduced accordingly, thereby reducing the frame size of the vehicle-mounted display device 10 as a whole.
[0029] In one embodiment, the light guide column structure 510 may include a plurality of light guide columns to form a discontinuous ring structure, and the auxiliary light source 520 is disposed between adjacent light guide columns and emits light toward at least one of the light guide columns. Figure 3 , Figure 3 for Figure 2 In this embodiment, the light guide column structure 510 corresponds to the side of the display panel 410, and includes a first light guide column 511, a second light guide column 512, a third light guide column 513 and a fourth light guide column 514 that are not connected. The auxiliary light source 520 includes a first auxiliary light source 521, a second auxiliary light source 522, a third auxiliary light source 523 and a fourth auxiliary light source 524. The first auxiliary light source 521 is disposed between the first light guide column 511 and the fourth light guide column 514 and emits light toward at least one of the first light guide column 511 and the fourth light guide column 514. The second auxiliary light source 522 is disposed between the first light guide column 511 and the fourth light guide column 514. The first light guide column 511 is disposed between the second light guide column 512 and emits light toward at least one of the first light guide column 511 and the second light guide column 512. The third auxiliary light source 523 is disposed between the second light guide column 512 and the third light guide column 513 and emits light toward at least one of the second light guide column 512 and the third light guide column 513. The fourth auxiliary light source 524 is disposed between the third light guide column 513 and the fourth light guide column 514 and emits light toward at least one of the third light guide column 513 and the fourth light guide column 514, so as to ensure that light is incident on each light guide column.
[0030] In this embodiment, the display panel 410 has a first side 411, a second side 412, a third side 413 and a fourth side 414 that are connected. The first to fourth light guide columns are respectively arranged corresponding to the four sides of the display panel 410, and the first to fourth auxiliary light sources are respectively arranged between adjacent light guide columns, for example, arranged near the four corners of the display panel 410. The light emitted by each auxiliary light source can be transmitted through the corresponding light guide column and then irradiated to the first support portion 121 to increase the light at the first support portion 121, so that the user is not easy to see the edge of the optical film material 300 and the first support portion 121.
[0031] Please refer to Figure 4 , Figure 4 FIG. 1 is a schematic diagram of another embodiment of the vehicle-mounted display device 10 of the present utility model. Figure 4 As shown, the first support portion 121 has a second bearing surface 123, and the first support portion 121 and the second support portion 122 are connected via a first connecting surface 124. Figure 2 The difference from the embodiment shown is that in this embodiment, the vehicle-mounted display device 10 further includes a second reflective sheet 700, which is disposed on the second carrying surface 123 and the first connecting surface 124. In this way, among the light rays irradiated to the first supporting portion 121 by each light guide column, part of the light rays can be reflected again by the second reflective sheet 700 to further brighten the brightness of the first supporting portion 121. Figure 4In the embodiment, the second reflective sheet 700 disposed on the second supporting surface 123 and the first connecting surface 124 are connected to each other and are continuous. In other embodiments, this is not limited to the embodiment, and the second reflective sheet 700 disposed on the second supporting surface 123 and the first connecting surface 124 may not be connected to each other and may be discontinuous.
[0032] Please refer to Figure 5 , Figure 5 FIG. 1 is a schematic diagram of another embodiment of the vehicle-mounted display device 10 of the present utility model. Figure 2 The difference between the embodiment shown is that in this embodiment, Figure 5 As shown, the auxiliary light guide component 500 is disposed on (the lower surface of) the display panel 410 adjacent to the edge of the display panel 410. The auxiliary light guide component 500 includes a first reflective sheet 530 and a black double-sided adhesive tape 540, and the first reflective sheet 530 is fixed to the display panel 410 via the black double-sided adhesive tape 540. In one embodiment, the first reflective sheet 530 is a white reflective sheet (or a reflective sheet coated with white ink) or a mirror reflective sheet.
[0033] In this embodiment, when the vehicle-mounted display device 10 is in normal use, after the light emitted by each light source 201 on the light board 200 passes through the optical film material 300, part of the light can reach the first reflective sheet 530 at the edge of the display panel 410. This part of the light is reflected by the first reflective sheet 530 and irradiated to the first support portion 121, so that the first support portion 121 is brightened, and the user is not easy to see the edge of the optical film material 300, nor the first support portion 121, so that the size of the optical film material 300 in the peripheral area BA can be reduced, and correspondingly, the size of the supporting frame 100 in the peripheral area BA can also be reduced, and the frame size of the vehicle-mounted display device 10 is reduced as a whole. Further, since the first reflective sheet 530 is arranged on its lower surface adjacent to the edge of the display panel 410 through the black double-sided tape 540, the black double-sided tape 540 has a better light absorption effect, which can ensure that there is no unnecessary light in the display panel 410 here.
[0034] Please refer to Figure 6 , Figure 6 FIG. 1 is a schematic diagram of another embodiment of the vehicle-mounted display device 10 of the present utility model. Figure 6 As shown, the first support portion 121 has a second bearing surface 123, and the first support portion 121 and the second support portion 122 are connected via a first connecting surface 124. Figure 5 The difference between the illustrated embodiment and the vehicle-mounted display device 10 is that the vehicle-mounted display device 10 further includes a second reflective sheet 700, which is disposed on the second carrying surface 123 and the first connecting surface 124. Thus, among the light reflected by the first reflective sheet 530 to the first supporting portion 121, part of the light can be reflected again by the second reflective sheet 700 to further increase the brightness of the first supporting portion 121.
[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first support portion 121 is connected to the first bearing surface 111 via a connecting inclined surface 125, and the vehicle-mounted display device 10 further includes a third reflector 800, which is disposed on the connecting inclined surface 125. When the vehicle-mounted display device 10 is in normal use, the light emitted by each light source 201 on the light board 200 can be transmitted toward the optical film material 201 through reflection by the third reflector 800 when irradiating the third reflector 800, thereby ensuring the light utilization rate of the light board 200. In one embodiment, the second reflector 700 and the third reflector 800 can be connected to each other or integrally formed, and in other embodiments, the second reflector 700 and the third reflector 800 can also be not connected.
[0036] In the utility model, when the vehicle-mounted display device is in use, the auxiliary light-guiding component can provide light to the first supporting portion, so that the first supporting portion is brightened, and the user cannot easily see the edge of the optical film material or the first supporting portion, so that the size of the optical film material in the peripheral area can be reduced. Correspondingly, the size of the supporting frame in the peripheral area can also be reduced, thereby reducing the frame size of the vehicle-mounted display device as a whole.
[0037] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
