Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted display screens, in particular to an integrated display screen without a center frame. Background Art

[0002] As a crucial interface for human-machine interaction in modern vehicles, in-vehicle displays are constantly evolving in functionality and technology, driven by the advancement of automotive intelligence. Simultaneously, these displays are becoming increasingly simple and thinner. Traditional in-vehicle displays retain a mid-frame backlight module design, with the backlight rear housing and display front housing separated. This results in a thicker overall size after assembly, which is inconsistent with the development trend of in-vehicle displays. Furthermore, the thinner the display, the higher the heat dissipation requirements. Failure to dissipate heat effectively can lead to unstable display operation, impacting operation. Utility Model Content

[0003] In response to the above-mentioned problems, the purpose of the present invention is to design a frameless integrated display screen, which reduces the thickness of the display screen by adopting an integrated rear shell structure, while improving the heat dissipation capacity of the display screen, thereby preventing the display screen from being unable to operate stably and affecting operation.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A frameless integrated display screen is designed, comprising a glass display assembly and a back shell for supporting the glass display assembly. The glass display assembly covers the back shell to form a storage space. An optical assembly is disposed in the storage space. The optical assembly includes a film material located below the glass display assembly and fixed to the back shell, and an LED light strip attached to the side wall of the back shell. The entire bottom surface of the back shell is covered with a heat dissipation foil for conducting heat generated by the LED light strip.

[0006] This design features a frameless, integrated display with a die-cast backshell. The glass display assembly is directly bonded to the backshell, eliminating the front shell, middle frame, bracket, and backlight backshell modules found in traditional display structures. Instead, these components are integrated into a single unit, reducing the number of parts and, in turn, the thickness of the display assembly. The LED light strips are mounted sideways, replacing the inline mounting method at the bottom of the backshell. These LED light strips are bonded to the side walls of the backshell, with the LEDs facing the side of the film. This reduces the thickness of the LED light strip and film, further reducing the thickness of the backshell and the display. To improve heat dissipation, a heat sink foil is applied to the bottom of the backshell, fully covering it. This foil quickly transfers heat generated by the LED light strips to the entire backshell, shifting from localized heat dissipation to a global heat dissipation approach. This design effectively reduces the thickness of the display, enhancing its aesthetic design while also improving its heat dissipation capacity. This avoids the risk of unstable operation and operational issues caused by reduced heat dissipation due to a reduction in thickness.

[0007] Furthermore, a limiting retaining wall is provided around the side of the end surface where the rear shell and the glass display assembly are in contact, and the glass display assembly is flush with the top end of the limiting retaining wall.

[0008] The rear case is rectangular in shape, with retaining walls around its top. Adhesive strips are attached to the sides of the retaining walls, and the glass display assembly fits directly into the grooves created by the retaining walls. The retaining walls protect the glass display assembly from damage caused by bumps and collisions. This design also increases the screen-to-body ratio of the display, eliminates the traditional front cover, and reduces the overall thickness of the display.

[0009] Furthermore, the rear shell includes a first side wall and a second side wall that are arranged opposite to each other, the LED light bar is attached to the first side wall, and the second side wall is provided with a limiting portion for limiting the movement of the film material.

[0010] The back shell adopts a rectangular back shell, which has a first side wall and a second side wall relative to each other. The LED light strip is fixed on the first side wall, and a limit part is set on the second side wall to limit the movement of the film material. When the film material is assembled into the back shell, the film material cannot move under the action of the limit part, thereby ensuring the stability of the film material assembly. Through this design, the middle frame used to press and fix the film material is eliminated, and the number of parts is optimized.

[0011] Furthermore, the limiting portion is a limiting groove, and the edge of the film material is provided with a limiting protrusion that can be inserted into the limiting groove.

[0012] The limiting structure between the membrane material and the rear shell can adopt an insertion limiting method. Several limiting grooves are opened on the second side wall of the rear shell, and limiting protrusions are designed corresponding to the edges of the membrane material. During assembly, the limiting protrusions are directly inserted into the limiting grooves, thereby limiting the movement of the membrane material from multiple directions.

[0013] Furthermore, the first side wall is provided with a support platform, and the film material is placed on the support platform near the edge of the first side wall.

[0014] A support platform is set on the first side wall. When the membrane material is installed on the rear shell, the limiting protrusion of the membrane material is inserted into the limiting groove of the second side wall, and the side of the membrane material opposite to the limiting protrusion is overlapped on the support platform, thereby ensuring the stability of the membrane material after assembly.

[0015] Furthermore, a support block for supporting the film material is provided at an edge of the bottom of the rear shell close to the second side wall.

[0016] In order to further increase the strength and stability of the film material support, two support blocks are respectively set at two right angles near the second side wall of the rear shell. The two support blocks are perpendicular to each other and fit the side wall of the rear shell to support adjacent edges of the film material.

[0017] Furthermore, a placement groove is provided at the bottom of the rear shell, and the support block is located in the placement groove.

[0018] The support block is attached to the bottom of the back shell with adhesive strips. To facilitate positioning, a placement slot is provided on the back shell where the support block is attached. When attaching and placing the support block, simply place it directly into the placement slot to avoid position deviation during placement.

[0019] Furthermore, the rear shell is provided with a first through hole and a second through hole, the first through hole is used for the flexible flat cable of the glass display assembly to pass through, and the second through hole is used for the flexible flat cable of the LED light bar to pass through.

[0020] The glass display assembly and LED light strip need to be electrically connected to the circuit board on the back of the rear shell through a flexible cable. In order to ensure the integrity of the rear shell shape, a first through hole and a second through hole are opened on the rear shell for the flexible cable of the glass display assembly and the flexible cable of the LED light strip to pass through.

[0021] Furthermore, the first through hole is located on the first side wall, and the second through hole is located on the bottom of the rear shell.

[0022] The flexible cable for the glass display assembly connects to the side of the glass display assembly, adjacent to the first sidewall. Therefore, a first through-hole is provided on the first sidewall to facilitate the cable's passage. The flexible cable for the LED light strip needs to pass through the bottom of the rear case after routing, so a second through-hole is provided on the rear case's bottom.

[0023] Furthermore, the heat dissipation foil is provided with an avoidance gap to avoid the second through hole and the flexible cable of the LED light strip.

[0024] The heat sink foil is attached to the bottom of the back cover. In order to avoid the second through hole and the routing of the flexible cable of the LED light strip, the heat sink foil is designed to avoid the gap to prevent the heat sink foil from contacting the flexible cable.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This design features a frameless, integrated display with a die-cast backshell. The glass display assembly is directly bonded to the backshell, eliminating the front shell, middle frame, bracket, and backlight backshell modules found in traditional display structures. Instead, these components are integrated into a single unit, reducing the number of parts and, in turn, the thickness of the display assembly. The LED light strips are mounted sideways, replacing the inline mounting method at the bottom of the backshell. These LED light strips are bonded to the side walls of the backshell, with the LEDs facing the side of the film. This reduces the thickness of the LED light strip and film, further reducing the thickness of the backshell and the display. To improve heat dissipation, a heat sink foil is applied to the bottom of the backshell, fully covering it. This foil quickly transfers heat generated by the LED light strips to the entire backshell, shifting from localized heat dissipation to a global heat dissipation approach. This design effectively reduces the thickness of the display, enhancing its aesthetic design while also improving its heat dissipation capacity. This avoids the risk of unstable operation and operational issues caused by reduced heat dissipation due to a reduction in thickness. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] like Figures 1 to 5 As shown, this embodiment provides a frameless integrated display screen. The display screen is rectangular in shape and includes a glass display assembly 1 and a back shell 2 for supporting the glass display assembly 1. The back shell 2 is provided with a retaining wall 21 around the end surface where it contacts the glass display assembly 1. Adhesive strips are attached to the back shell 2 along the sides of the retaining wall 21. The glass display assembly 1 is directly attached to the groove enclosed by the retaining wall 21, and the top of the glass display assembly 1 is flush with the top of the retaining wall 21. The retaining wall 21 protects the glass display assembly 1 from damage caused by collisions. The glass display assembly 1 covers the back shell 2 to form a storage space. An optical assembly 3 is disposed within the storage space. The optical assembly 3 includes a film 31 located below the glass display assembly 1 and fixed to the back shell 2, and an LED light strip 32 attached to the side wall of the back shell 2. The entire bottom surface of the back shell 2 is covered with a heat dissipation foil 4 to conduct heat generated by the LED light strip 32.

[0035] The present embodiment of the frameless integrated display screen has a die-cast rear shell 2, with the glass display assembly 1 directly attached to the rear shell 2. This increases the screen-to-body ratio of the display screen and eliminates the front shell, middle frame, bracket, and backlight rear shell modules in the traditional display screen structure. The front shell, middle frame, bracket, and backlight rear shell functions are integrated into one, reducing the number of parts and, in turn, the thickness of the display screen assembly. The LED light bar 32 adopts a side-entry installation method instead of the in-line installation method at the bottom of the rear shell. The LED light bar 32 is attached to the side wall of the rear shell 2, with the lamp beads facing the side of the film material 31. This reduces the thickness of the LED light bar 32 and the film material 31, reduces the thickness of the rear shell 2, and further reduces the thickness of the display screen. To improve the heat dissipation capacity, a heat dissipation foil 4 is laid on the bottom of the rear shell 2. The heat dissipation foil 4 fully covers the bottom of the rear shell 2 and quickly conducts the heat generated by the LED light bar 32 to the entire rear shell 2, changing the local heat dissipation method to an overall heat dissipation method. Through the above design, the thickness of the display screen is effectively reduced, the aesthetics of the display screen design is improved, and the heat dissipation capacity of the display screen is improved, thereby avoiding the problem of unstable operation of the display screen and affecting operation due to the weakening of the heat dissipation capacity caused by the reduction of the display screen thickness.

[0036] like Figure 2 and Figure 5 As shown, the rear housing 2 is a rectangular rear housing having opposing first and second sidewalls 22 and 23. An LED light strip 32 is affixed to the first sidewall 22. The second sidewall 23 is provided with a plurality of retaining members for limiting the movement of a film 31. These retaining members can be designed as retaining grooves 24. Of course, the retaining members can also be designed in other forms as long as they meet the retaining function. The edges of the film 31 are provided with retaining protrusions 311 that insert into the retaining grooves 24. The retaining structure between the film 31 and the rear housing 2 can be implemented using an insertion-type retaining mechanism. Several retaining grooves 24 are provided on the second sidewall 23 of the rear housing 2, and corresponding retaining protrusions 311 are designed on the edges of the film 31. During assembly, the retaining protrusions 311 directly engage with the retaining grooves 24, thereby restricting the movement of the film 31 in multiple directions. This ensures the stability of the assembly of the film 31. This design eliminates the need for a midframe for press-fitting the film 31, thus optimizing the number of components.

[0037] like Figure 2 and Figure 5As shown, a support platform 25 is provided on the first side wall 22, and the edge of the film 31 near the first side wall 22 is placed on the support platform 25. A support block 26 for supporting the film 31 is provided on the edge of the bottom of the rear shell 2 near the second side wall 23. A placement groove 27 is provided on the bottom of the rear shell 2, and the support block 26 is located within the placement groove 27. The support platform 25 is provided on the first side wall 22. When the film 31 is assembled with the rear shell 2, the limiting protrusion 311 of the film 31 is inserted into the limiting groove 24 of the second side wall 23, and the side of the film 31 opposite the limiting protrusion 311 overlaps the support platform 25. Two support blocks 26 are respectively provided at two right angles to the second side wall 23 of the rear shell 2. The two support blocks 26 are perpendicular to each other and abut the side walls of the rear shell 2, respectively supporting the adjacent edges of the film 31 to ensure the stability of the film 31 after assembly. The support block 26 is attached to the bottom of the rear shell 2 by means of adhesive strips. To facilitate positioning, a placement groove 27 is provided at the attachment position of the support block 26 at the bottom of the rear shell 2. When attaching and placing the support block 26, it can be directly placed into the placement groove 27 to avoid position deviation during placement.

[0038] like Figure 2 and Figure 5 As shown, the back cover 2 is provided with a first through-hole 28 and a second through-hole 29. The first through-hole 28 is for the flexible flat cable of the glass display assembly 1, and the second through-hole 29 is for the flexible flat cable of the LED light strip 32. The first through-hole 28 is located on the first side wall 22, and the second through-hole 29 is located on the bottom of the back cover 2. The glass display assembly 1 and the LED light strip 32 need to be electrically connected to the circuit board on the back of the back cover 2 via flexible flat cables. To ensure the integrity of the back cover 2, the first through-hole 28 and the second through-hole 29 are provided on the back cover 2 to allow for the flexible flat cables of the glass display assembly 1 and the LED light strip 32 to pass through. The flexible flat cable of the glass display assembly 1 is connected to the side of the glass display assembly 1, adjacent to the first side wall 22. Therefore, the first through-hole 28 is provided on the first side wall 22 to facilitate the flexible flat cable passage. The flexible flat cable of the LED light strip 32 needs to pass through the bottom of the back cover 2 after routing, so the second through-hole 29 is provided on the bottom of the back cover 2. The heat dissipation foil 4 is attached to the bottom of the rear housing 2 . To avoid the second through hole 29 and the routing of the flexible cable of the LED light strip 32 , the heat dissipation foil 4 is designed to avoid the notch 41 to prevent the heat dissipation foil 4 from contacting the flexible cable.
