Detailed Description of the Embodiments

[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0028] In the related art, the display assembly includes a plurality of structural members, which are respectively used for the assembly of the display module, the backlight film material, and the light source. After the display module, the backlight film material, and the light source are assembled on the plurality of structural members, the plurality of structural members can be assembled together. However, the plurality of structural members will cause the structure of the display assembly to be thick and heavy, and after the assembly of the plurality of structural members, an appearance part needs to be additionally configured outside the plurality of structural members, further increasing the weight of the display assembly and resulting in a relatively reduced display size of the display assembly, affecting the user experience.

[0029] Therefore, the present utility model proposes a display assembly 100 and a vehicle, which can achieve the thinness and narrow bezel of the display assembly 100.

[0030] Refer to Figure 1, according to the display assembly 100 in the embodiments of the present utility model, the display assembly 100 may include a base 10, a display module 20, a backlight film 30 and a light source 40 disposed on the base 10. The backlight film 30 is disposed on the backlight side of the display module 20, and the light source 40 is disposed on the side of the backlight film 30 facing away from the display module 20. In this way, through the base 10, the installation of the display module 20, the backlight film 30 and the light source 40 can be realized, and the thinness and narrow bezel of the display assembly 100 can be achieved.

[0031] Specifically, the display module 20, the backlight film 30 and the light source 40 are all disposed on the base 10. The base 10 provides an assembly position for the display module 20, the backlight film 30 and the light source 40, realizing the assembly of the display assembly 100. And since the display module 20, the backlight film 30 and the light source 40 are all disposed on the same base 10, compared with the foregoing related technologies, the display assembly 100 can achieve thinness and narrow bezel.

[0032] In addition, the backlight film is disposed on the backlight side of the display module 20, and the light source 40 is disposed on the side of the backlight film 30 facing away from the display module 20. When the display assembly 100 is working, the light source 40 can release light to the display module 20, and the light can first pass through the backlight film 30. The backlight film 30 realizes a light homogenizing effect on the light, and then illuminates the display module 20, realizing the display function of the display assembly 100.

[0033] Referring to Figure 1 , in some embodiments of the present utility model, the base 10 includes an installation space 50 with an opening. The display module 20 is disposed at the opening of the base 10, and at least a part of the light source 40 and the backlight film 30 are disposed in the installation space 50. It can be understood that the display module 20 and the base 10 cooperate to form a closed installation space 50. By disposing at least a part of the light source 40 and at least a part of the backlight film 30 in the installation space 50, the influence of the external environment on the light source 40 and the backlight film 30 can be reduced, thereby improving the working stability of the display assembly 100.

[0034] Referring to Figure 1 , in some embodiments of the present utility model, the light source 40 can be stacked on the inner bottom surface of the installation space 50 and opposite to the opening. Specifically, stacking the light source 40 on the inner bottom surface of the installation space 50 can improve the assembly stability of the light source 40 on the base 10. And combined with the foregoing embodiments, the display module 20 is disposed at the opening of the base 10, and the light source 40 disposed in the installation space 50 can be opposite to the opening, so that the light source 40 can better illuminate the display module 20 to better realize the display function of the display assembly.

[0035] Referring to Figure 1, in some embodiments of the present utility model, the installation space 50 has a first surface 51, a second surface 52 and a third surface 53. The first surface 51 and the second surface 52 are arranged along the thickness direction of the display screen assembly 100, and the second surface 52 is closer to the opening than the first surface 51. The second surface 52 extends outward compared to the first surface 51, and the third surface 53 is connected between the first surface 51 and the second surface 52 to construct a first stepped structure. The backlight film material 30 is arranged on the third surface 53. In this way, the first stepped structure can facilitate the assembly of the backlight film material 30 and improve the installation stability of the backlight film material 30 on the seat body 10.

[0036] Optionally, the first surface 51 and the second surface 52 are arranged along the thickness direction of the display screen assembly 100. It can be understood that the first surface 51 and the second surface 52 can extend along the thickness direction and are arranged along the thickness direction. The third surface 53 is respectively connected to the first surface 51 and the second surface 52 to form a first stepped structure. The backlight film material 30 can be arranged on the third surface 53, that is, the backlight film material 30 can be laminated on the first stepped structure to improve the installation stability of the backlight film material 30. And in combination with the foregoing embodiments, the light source 40 is laminated on the inner bottom surface of the installation space 50. In this way, in the installation space 50, the backlight film material 30 and the light source 40 can be laminated and arranged so that the light emitted by the light source 40 can pass through the backlight film material 30 to the maximum extent, and the light homogenizing effect of the light is realized through the backlight film material 30, thereby improving the display performance of the display screen assembly 100.

[0037] In addition, in some specific examples, the backlight film material 30 can be connected to the third surface 53 by means of bonding; in other specific examples, the backlight film material 30 can be positioned on the third surface 53 through a structural member.

[0038] Refer to Figure 1 , in some embodiments of the present utility model, there is an air layer 60 between the light source 40 and the backlight film material 30. Specifically, when the display screen assembly 100 is working, the light emitted by the light source 40 first radiates and diverges through the air layer 60, and then passes through the backlight film material 30. The light homogenizing effect is realized through the backlight film material 30, and finally the display module 20 is illuminated to realize the display of the display screen assembly 100. In addition, the air layer 60 can help the light source 40 dissipate heat and avoid affecting the performance of the display screen assembly 100 due to excessive heat.

[0039] Refer to Figure 1, in some embodiments of the present utility model, the installation space 50 further has a fourth surface 54. The fourth surface 54 and the third surface 53 are arranged along the thickness direction, and the fourth surface 54 is closer to the opening than the third surface 53. The fourth surface 54 extends outward compared to the third surface 53, and the second surface 52 is connected between the third surface 53 and the fourth surface 54 to construct a second step structure, and the display module 20 is disposed on the fourth surface 54. In this way, the second step structure can facilitate the assembly of the display module 20 and improve the installation stability of the display module 20 on the seat body 10.

[0040] Optionally, the third surface 53 and the fourth surface 54 are arranged along the thickness direction of the display screen assembly 100. It can be understood that the third surface 53 and the fourth surface 54 can extend along the vertical direction of the thickness direction and are arranged along the thickness direction. The second surface 52 is respectively connected to the third surface 53 and the fourth surface 54 to form a second step structure, and the display module 20 can be arranged on the fourth surface 54, that is, the display module 20 can be stacked on the second step structure to improve the installation stability of the display module 20. And in combination with the foregoing embodiments, the light source 40 is stacked on the inner bottom surface of the installation space 50, and the light source 40 and the backlight film material 30 are stacked. In this way, in the installation space 50, the light source 40, the backlight film material 30, and the display module 20 can be stacked so that the light emitted by the light source 40 can pass through the backlight film material 30 to the greatest extent, and the light homogenizing effect of the light is realized through the backlight film material 30, and then the light illuminates the display module 20 to the greatest extent, improving the display performance of the display screen assembly 100.

[0041] And in combination with the foregoing, the first surface 51, the second surface 52, the third surface 53, and the fourth surface 54 can form a continuous step structure. It can be understood that in the direction from the opening of the installation space 50 to the inner bottom surface of the installation space 50, the second step structure and the first step structure are arranged in sequence, which is convenient for the display module 20 and the backlight film material 30 to be arranged in the installation space 50.

[0042] In addition, in some specific examples, the display module 20 can be connected to the fourth surface 54 by bonding.

[0043] Refer to Figure 1, in some embodiments of the present utility model, there is a first predetermined distance L1 between the light source 40 and the inner peripheral wall of the installation space 50 to facilitate the assembly of the light source 40 in the installation space 50; specifically, the first surface 51 extends in the thickness direction and has opposite ends. One end of the first surface 51 is connected to the inner bottom surface of the installation space 50, and the other end is connected to the third surface 53. The light source 40 is stacked on the inner bottom surface of the installation space 50, and the inner peripheral wall of the installation space 50 corresponding to the light source 40 can be the first surface 51. Therefore, there is a first predetermined distance L1 between the light source 40 and the first surface 51, and the first predetermined distance L1 can provide an assembly allowance for the light source 40 to facilitate the assembly of the light source 40 in the installation space 50.

[0044] Refer to Figure 1 , in some embodiments of the present utility model, there is a second predetermined distance L2 between the backlight film material 30 and the inner peripheral wall of the installation space 50 to facilitate the assembly of the backlight film material 30 in the installation space 50 and provide a space for the deformation of the backlight film material 30; specifically, the second surface 52 extends in the thickness direction and has opposite ends. One end of the second surface 52 is connected to the third surface 53, and the other end is connected to the fourth surface 54. The backlight film material 30 is stacked on the third surface 53, and the inner peripheral wall of the installation space 50 corresponding to the backlight film material 30 can be the second surface 52. Therefore, there is a second predetermined distance L2 between the backlight friction and the second surface 52, and the second predetermined distance L2 can provide an assembly allowance for the backlight film material 30 to facilitate the assembly of the backlight film material 30 in the installation space 50. Moreover, when the backlight film material 30 expands and deforms, the second predetermined distance L2 can provide a space for the deformation of the backlight film material 30.

[0045] Refer to Figure 1 , in some embodiments of the present utility model, the display screen assembly 100 may further include a limiting bracket 70. The limiting bracket 70 is disposed between the display module 20 and the backlight film material 30, and in the thickness direction of the display screen assembly 100, the limiting bracket 70 is spaced apart from the backlight film material 30 by a predetermined distance; in this way, the installation of the backlight film material 30 can be facilitated, and the contact between the backlight film material 30 and the display module 20 can be avoided to prevent damage.

[0046] Specifically, in combination with the foregoing embodiments, the light source 40, the backlight film material 30, and the display module 20 are stacked in the thickness direction of the display screen assembly 100. A limiting bracket 70 is provided between the backlight film material 30 and the display module 20. The limiting bracket 70 can cooperate with the third surface 53 to form a space suitable for installing the backlight film material 30, facilitating the assembly of the backlight film material 30 on the seat body 10. Moreover, as the display screen assembly 100 operates, the backlight film material 30 will expand and deform. The limiting bracket 70 can limit the contact between the backlight film material 30 and the display module 20, that is, when the backlight film material 30 expands and deforms, it will abut against the limiting bracket 70, preventing damage caused by mutual interference between the backlight film material 30 and the display module 20.

[0047] Referring to Figure 2 , in some embodiments of the present invention, the light source 40 includes a MINILED light source 40 (MINILED stands for sub - millimeter light - emitting diode); specifically, the MINILED light source 40 may include a plurality of MINILED lamp beads. The plurality of MINILED lamp beads are arranged in regions, and the number of regions is determined according to the size and resolution of the display module 20. The brightness of each region of lamp beads can be precisely controlled to meet the requirements of the video signal. For example, under a black interface, the LEDs can be precisely turned off in different regions, achieving an effect close to pure black, thereby realizing high static / dynamic contrast, excellent color reproduction, detailed display, and lower overall power consumption.

[0048] Referring to Figure 1 , in some embodiments of the present invention, the display screen assembly 100 may further include a limiting bracket 70. The limiting bracket 70 can cooperate with the seat body 10 to form a space suitable for installing the backlight film material 30, and the limiting bracket 70 can limit the expansion of the backlight film material 30, avoiding damage caused by interference between the backlight film material 30 and the display module 20.

[0049] Among them, the limiting bracket 70 includes a first bracket 71, a second bracket 72, and a third bracket; the first bracket 71 is stacked and connected to the inner peripheral wall of the installation space 50, the second bracket 72 is connected to the first bracket 71 and extends along the direction from the center to the edge of the display screen assembly 100, and the third bracket is connected to the first bracket 71 and is stacked and connected to the edge portion of the opening; in this way, the installation strength of the limiting bracket 70 on the seat body 10 can be improved, and the working stability of the display screen assembly 100 can be enhanced.

[0050] Specifically, in combination with the foregoing embodiments, the inner peripheral wall of the installation space 50 corresponding to the backlight film material 30 is the second surface 52. In this way, the first bracket 71 of the limit bracket 70 can be stacked on the second surface 52. The second bracket 72 can be connected to the first bracket 71 and extend along the direction from the center to the edge of the display screen assembly 100, and be spaced apart from the backlight film material 30 by a predetermined distance in the thickness direction to limit the expanded and deformed backlight film material 30 in the thickness direction and prevent the backlight film material 30 from interfering with the display module 20 and causing damage. The third bracket can be connected to the first bracket 71 and stacked and connected to the edge portion of the opening. In combination with the foregoing, the edge portion of the opening can be the fourth surface 54. In other words, the third bracket can be stacked and connected on the fourth surface 54, and the fourth surface 54 extends in the vertical direction of the thickness direction, that is, along the direction from the center to the periphery of the display screen assembly 100. In this way, through the stacked connection of the first bracket 71 and the second surface 52 and the stacked connection of the third bracket and the fourth surface 54, the installation area between the limit bracket 70 and the base 10 can be increased in multiple directions, thereby improving the connection strength between the limit bracket 70 and the base 10.

[0051] In addition, in some specific examples, at least one of the first bracket 71 and the third bracket can be connected to the base 10 by means of bonding and snap connection. For example, the first bracket 71 can be provided with a convex card, and the second surface 52 can be provided with a card slot, and the convex card and the card slot can be fitted in an engaged manner.

[0052] Secondly, referring to Figure 1 , in some specific examples, the limit bracket 70 includes a first bracket 71 and a second bracket 72. The first bracket 71 is connected to the inner peripheral wall of the installation space, and the second bracket 72 is used to limit the expanded and deformed backlight film material 30.

[0053] Referring to Figure 1 , according to the vehicle in the embodiment of the present invention, the vehicle can include a vehicle body and the display screen assembly 100 in the foregoing embodiments.

[0054] Among them, the display screen assembly 100 is provided on the vehicle body. By applying the foregoing display screen assembly 100, the thinness and narrow bezel of the in-vehicle display can be realized, and the user experience can be improved.

[0055] Specifically, the seat body 10 includes an installation space 50 with an opening. The installation space 50 has a first surface 51, a second surface 52, a third surface 53, and a fourth surface 54. The first surface 51, the second surface 52, the third surface 53, and the fourth surface 54 are connected to form a first stepped structure and a second stepped structure. The first stepped structure and the second stepped structure are arranged in sequence in the thickness direction and in the direction from the inner bottom surface of the installation space 50 to the opening of the installation space 50, so as to provide installation positions for the backlight film material 30 and the display module 20. In other words, the light source 40, the backlight film material 30, and the display module 20 can be stacked in the thickness direction of the display screen assembly 100 to improve the display effect of the display screen assembly 100, and the assembly of the light source 40, the backlight film material 30, and the display module 20 can be realized through the seat body 10, so as to realize the thinning and narrow bezeling of the display screen assembly 100.

[0056] In addition, there is an air layer 60 between the light source 40 and the backlight film material 30. The light emitted by the light source 40 can be radiated and diverged through the air layer 60, and then evenly distributed by the backlight film material 30, and finally illuminate the display module 20 to realize the display function; and it can also help the light source 40 dissipate heat and avoid affecting the display performance.

[0057] In addition, there is a first predetermined distance L1 between the light source 40 and the first surface 51 to facilitate the assembly of the light source 40 on the seat body 10; there is a second predetermined distance L2 between the backlight film material 30 and the second surface 52 to facilitate the assembly of the backlight film material 30 on the seat body 10 and provide a space for the expansion and deformation of the backlight film material 30.

[0058] Furthermore, the seat body 10 is provided with a limiting bracket 70. The limiting bracket 70 includes a first bracket 71, a second bracket 72, and a third bracket. The first bracket 71 is stacked and connected to the second surface 52. The second bracket 72 extends vertically in the thickness direction. The second bracket 72 can be spaced from the backlight film material 30 by a predetermined distance in the thickness direction. The third bracket is stacked and connected to the fourth surface 54; in short, the second bracket 72 is used to prevent the backlight film material 30 with expanded deformation from interfering with the display module 20; the installation area of the limiting bracket 70 and the seat body 10 can be increased through the first bracket 71 and the third bracket, and the first bracket 71 and the third bracket can be connected to the seat body 10 in multiple directions, so that the connection strength between the limiting bracket 70 and the seat body 10 can be greatly improved.

[0059] In some embodiments of the present invention, the display screen assembly 100 further includes a circuit board assembly 90. The circuit board assembly 90 is disposed on the side of the seat body 10 facing away from the display module 20. In the height direction of the seat body 10, the height dimension of the circuit board assembly 90 is not greater than two-thirds of the height dimension of the seat body 10, so that the seat body 10 protrudes relative to the circuit board assembly 90 to form a floating-shaped display screen, improving the user experience.

[0060] Further, referring to Figure 1 , in some embodiments of the present utility model, the circuit board assembly 90 includes a housing 91 and at least two circuit boards. The at least two circuit boards include a first circuit board 92 and a second circuit board 93. The housing 91 is disposed on a side of the base 10 facing away from the display module 20, and together with the base 10, they enclose a receiving space. The first circuit board 92 and the second circuit board 93 can be disposed in the receiving space and are vertically arranged on a side of the base 10 facing away from the display module 20 along the vertical direction of the height of the display screen assembly 100. Specifically, compared with a single large circuit board disposed on a side of the base 10 facing away from the display module 20 in the related art, in this embodiment, two small circuit boards are used to replace the single large circuit board. The two small circuit boards can accommodate the original electrical components on the single large circuit board, and the two small circuit boards can be vertically arranged along the vertical direction of the height of the display screen assembly 100, thereby reducing the size of the circuit board assembly 90 in the height direction, so that the base 10 extends upward relative to the circuit board assembly 90 to form a suspended-shaped display screen, improving the user experience.

[0061] In addition, the base 10 has a first connecting post, and the housing 91 has a second connecting post. The first connecting post corresponds to the second connecting post and is connected by a fastener. The second circuit board 93 has a relief hole, and when the first connecting post is connected to the second connecting post, it can pass through the relief hole of the second circuit board 93 to position the second circuit board 93 in the receiving space. In addition, the first circuit board 92 can be electrically connected to the display module 20 and the light source 40 to supply power to the light source 40 and the display module 20, and transmit signals to the display module 20. The second circuit board 93 can be electrically connected to the first circuit board 92, and through the second circuit board 93, it can transmit signals to the main controller of the vehicle, ultimately realizing the control of the display of the display screen assembly 100.

[0062] In some specific examples of the present utility model, the base 10 is connected with a first shielding portion 11, and the circuit board assembly 90 has a second shielding portion 95. The first shielding portion 11 and the second shielding portion 95 extend in the thickness direction to shield the gap between the display module 20 and the base 10, improving the sealing performance of the display screen assembly 100 and preventing external environmental pollution of the structural components in the installation space 50.

[0063] In some specific examples of the present utility model, the circuit board assembly 90 further includes a connecting seat.
