[0001] The present disclosure relates to a display device, and more particularly to a vehicle-mounted display device. Background Art

[0002] In-vehicle display devices are devices used to display information in vehicles, including, for example, dashboards, center consoles, and entertainment systems. The dashboard is usually used to display speed, rpm, fuel level, and other important information. The center console is usually used to control the audio, air conditioning, and other functions. The entertainment system is usually used to play music, movies, and games. In-vehicle display devices provide the information that drivers need and make vehicles safer and more comfortable. Therefore, with the development of technology, in-vehicle display devices are becoming an increasingly important component of vehicles.

[0003] In addition, narrow borders and thinness are two important trends in vehicle-mounted display devices. Narrow borders can make the display look larger and more eye-catching, while thinness can make the display more space-saving and easier to install inside the car. However, there is currently no simple and effective solution for narrow borders and thinness.

[0004] Therefore, how to propose a vehicle-mounted display device that can solve the above problems is one of the problems that the industry is eager to invest research and development resources to solve. Summary of the invention

[0005] In view of this, an object of the present disclosure is to provide a vehicle-mounted display device that can solve the above-mentioned problem.

[0006] In order to achieve the above-mentioned purpose, according to one embodiment of the present disclosure, a vehicle-mounted display device includes a cover plate, a display module, a frameless backlight module, a shell, a main circuit board and a mounting frame. The cover plate has a visible area and a non-visible area surrounding the visible area. The display module is at least partially located in the non-visible area and has a cable located in the non-visible area. The frameless backlight module is arranged on a side of the display module away from the cover plate. The shell includes a side wall, a first step and a second step. The side wall laterally covers the cover plate. The first step is connected to the inner side of the side wall and carries the cover plate. The first step has a through hole. The second step is connected to the inner side of the first step and carries the frameless backlight module. The main circuit board is arranged on the back of the shell. The cable passes through the through hole and is connected to the main circuit board. The mounting frame covers the main circuit board. The side wall laterally covers the connection between the mounting frame and the shell.

[0007] In one or more embodiments of the present disclosure, the mounting bracket further covers the opening of the through hole on the back side of the housing.

[0008] In one or more embodiments of the present disclosure, the bottom surface of the side wall and the bottom surface of the first step are located on the back surface of the housing. The bottom surface of the first step is recessed relative to the bottom surface of the side wall. The connecting portion is located on the bottom surface of the first step.

[0009] In one or more embodiments of the present disclosure, the through hole passes through the top surface and the bottom surface of the first step.

[0010] In one or more embodiments of the present disclosure, a top surface of the second step is recessed relative to a top surface of the first step.

[0011] In one or more embodiments of the present disclosure, the bottom surface of the first step and the bottom surface of the second step are located on the back surface of the housing, are flush with the bottom surface of the second step, and are at least partially covered by the mounting frame.

[0012] In one or more embodiments of the present disclosure, a side of the housing facing the cover plate forms an accommodation space, and the cover plate, the display module and the frameless backlight module are accommodated in the accommodation space.

[0052] The following will disclose multiple embodiments of the present disclosure with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. In other words, in some embodiments of the present disclosure, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and elements will be depicted in a simple schematic manner in the drawings.

[0053] Please refer to Figure 1 , Figure 2 as well as Figure 3 . Figure 1 FIG. 1 is a front view of a vehicle-mounted display device 100 according to an embodiment of the present disclosure. Figure 2 To illustrate Figure 1 A partial cross-sectional view of the vehicle-mounted display device 100 along the cutting line 2-2. Figure 3 To illustrate Figure 1 A partial cross-sectional view of the vehicle-mounted display device 100 along the cutting plane line 3-3. Figures 1 to 3 As shown, in this embodiment, the vehicle-mounted display device 100 includes a cover plate 110, a display module 120, a frameless backlight module 130, and a housing 140. The cover plate 110 has a visible area VA and a non-visible area BM surrounding the visible area VA. For example, a light shielding layer (not shown) may be provided at the bottom of the cover plate 110. The area of ​​the cover plate 110 covered by the light shielding layer is the non-visible area BM, and the area of ​​the cover plate 110 not covered by the light shielding layer is the visible area VA.

[0054] The display module 120 is at least partially located in the non-visible area BM, and has a flat cable 121 located in the non-visible area BM. For example, the flat cable 121 is, for example, a flexible printed circuit, and the display module 120 of this embodiment is a liquid crystal screen using a FOG (Film on Glass) process, but the present disclosure is not limited thereto. The frameless backlight module 130 is disposed on a side of the display module 120 away from the cover plate 110. For example, the frameless backlight module 130 includes a light source, a light guide plate, and at least one optical film (not shown), which will not be illustrated in detail here.

[0055] A side of the housing 140 facing the cover plate 110 forms an accommodation space S. The cover plate 110 , the display module 120 and the frameless backlight module 130 are accommodated in the accommodation space S of the integrated housing 140 .

[0056] Further, if Figure 2 As shown, the housing 140 includes a side wall 141, a first step 142, and a second step 143. The first step 142 is connected to the inner side 141s of the side wall 141, and supports the cover plate 110. That is, the side wall 141 and the first step 142 can together constitute a support portion for supporting the cover plate 110. The second step 143 is connected to the inner side 142s of the first step 142, and supports the frameless backlight module 130. Since the frameless backlight module 130 is directly supported on the second step 143, the frameless backlight module 130 shares the housing 140 with the cover plate 110 and the display module 120.

[0057] In detail, Figure 2 As shown, in this embodiment, the first step 142 of the housing 140 has a through hole H. The through hole H passes through the top surface 142t and the bottom surface 142b of the first step 142. The vehicle-mounted display device 100 further includes a main circuit board 150 and a mounting bracket 160. The main circuit board 150 is disposed on the back side 140b of the housing 140. That is, the main circuit board 150 is disposed outside the accommodating space S of the housing 140. The flat cable 121 passes through the through hole H of the first step 142 and is connected to the main circuit board 150. The mounting bracket 160 covers the main circuit board 150 and covers the opening of the through hole H located on the back side 140b of the housing 140.

[0058] From the above structural configuration, it can be seen that the main circuit board 150 disposed outside the shell 140 can effectively reduce the overall thickness of the vehicle display device 100, and the mounting frame 160 covering the back side 140b of the shell 140 can achieve the purpose of hiding the main circuit board 150 and the cable 121.

[0059] like Figure 2As shown, in this embodiment, the distance between the through hole H and the inner side surface 142s of the first step 142 is greater than zero. That is, the through hole H is not directly formed on the inner side surface 142s of the first step 142. In this way, the mechanical strength of the through hole H can be guaranteed. In other words, the housing 140 will not be easily deformed due to the through hole H formed on the first step 142.

[0060] In practical applications, the back surface 140b of the housing 140 may constitute a part of the exterior surface of the vehicle-mounted display device 100. That is, when the vehicle-mounted display device 100 is installed on a vehicle, the back surface 140b of the housing 140 is at least partially exposed.

[0061] In some embodiments, when the vehicle-mounted display device 100 is installed on a vehicle, the mounting frame 160 is shielded by the vehicle and is not exposed. Therefore, when determining the overall thickness of the vehicle-mounted display device 100 of these embodiments, the thickness of the housing 140 may be mainly used as the reference, and the thickness of the mounting frame 160 may be ignored.

[0062] like Figure 2 As shown, in this embodiment, the upper end of the side wall 141 laterally covers the cover plate 110. The lower end of the side wall 141 laterally covers the connection portion 161 between the mounting frame 160 and the shell 140. Specifically, the top surface 142t of the first step 142 is recessed relative to the top surface 141t of the side wall 141. It can be seen that the support portion formed by the side wall 141 and the first step 142 is recessed relative to the top surface 141t of the side wall 141. In addition, the bottom surface 141b of the side wall 141 and the bottom surface 142b of the first step 142 are located on the back surface 140b of the shell 140. The bottom surface 142b of the first step 142 is recessed relative to the bottom surface 141b of the side wall 141. The connection portion 161 between the mounting frame 160 and the shell 140 is located on the bottom surface 142b of the first step 142. It can be seen that the connection portion 161 between the mounting bracket 160 and the housing 140 is recessed relative to the bottom surface 141b of the side wall 141. Thus, the side wall 141 of the housing 140 can better protect other components of the vehicle display device 100 and increase the difficulty of the cover plate 110 and the mounting bracket 160 being arbitrarily disassembled.

[0063] like Figure 2As shown, in this embodiment, the bottom surface 142b of the first step 142 and the bottom surface 143b of the second step 143 are located on the back surface 140b of the housing 140. The bottom surface 142b of the first step 142 and the bottom surface 143b of the second step 143 are flush with each other and at least partially covered by the mounting bracket 160. In other embodiments, the bottom surface 142b of the first step 142 and the bottom surface 143b of the second step 143 are not flush with each other. For example, the bottom surface 143b of the second step 143 may be concave relative to the bottom surface 142b of the first step 142. In other embodiments, at least one of the bottom surface 142b of the first step 142 and the bottom surface 143b of the second step 143 may be a curved surface.

[0064] In some embodiments, the main circuit board 150 can be fixed or locked on the back side 140b of the housing 140, but the disclosure is not limited thereto. In some embodiments, the mounting frame 160 can be fixed or locked on the back side 140b of the housing 140, but the disclosure is not limited thereto.

[0065] like Figure 2 As shown, in this embodiment, the cover plate 110 is fixed to the first step 142 of the housing 140 by a fixing member 191. For example, the fixing member 191 is a double-sided adhesive tape (VHB), but the present disclosure is not limited thereto.

[0066] like Figure 2 As shown, in this embodiment, the top surface 143t of the second step 143 is recessed relative to the top surface 142t of the first step 142. Specifically, the second step 143 includes a first supporting portion 1431 and a second supporting portion 1432. The first supporting portion 1431 is connected to the inner side surface 142s of the first step 142 and supports the display module 120. The second supporting portion 1432 is connected to the first supporting portion 1431 and supports the frameless backlight module 130. It can be seen that the second step 143 uses the first supporting portion 1431 and the second supporting portion 1432 to support the display module 120 and the frameless backlight module 130 at different heights.

[0067] Furthermore, the vehicle-mounted display device 100 further includes a frame 170 and a fixing member 192. The frame 170 is disposed on the first carrying portion 1431. The frame 170 is carried on the first carrying portion 1431. The fixing member 192 is disposed on a side of the frame 170 away from the frameless backlight module 130. The display module 120 is carried on the frame 170 via the fixing member 192. In this way, the display module 120 can be carried on the first carrying portion 1431.

[0068] In some embodiments, the fixing member 192 is a cell tape to provide a buffer between the frame 170 and the display module 120 , but the disclosure is not limited thereto.

[0069] like Figure 2 As shown, in this embodiment, the vehicle-mounted display device 100 further includes an electrical connector 180. The electrical connector 180 is connected to the main circuit board 150 and is exposed through the mounting bracket 160. The electrical connector 180 is configured to be electrically connected to the vehicle.

[0070] In some embodiments, the electrical connector 180 is a high speed data connector that can transmit data and signals with a frequency of up to 6 GHz without being interfered by noise, which makes it very suitable for application in the automotive industry.

[0071] Please refer to Figure 4 , which is a partial cross-sectional view of another vehicle-mounted display device 200. Figure 4 As shown, in this embodiment, the vehicle display device 200 includes a cover plate 110, a display module 120, a frameless backlight module 130, a housing 240, a frame 170, fixing members 191, 192 and a back frame 241, wherein the cover plate 110, the display module 120, the frameless backlight module 130 and the fixing members 191, 192 are the same or similar to Figure 3 The embodiment shown in the figure, therefore, the structure and function of these components can refer to the above-mentioned related description, and will not be repeated here. It should be noted that the vehicle-mounted display device 200 of this embodiment is replaced by the housing 240 and the back frame 241. Figure 3 The integrated housing 140 is shown.

[0072] Specifically, if Figure 4 As shown, in this embodiment, the cover plate 110 is disposed on the housing 240 via the fixing member 191. The display module 120 is disposed on the back frame 241 via the fixing member 192 and the frame body 170. The frameless backlight module 130 is carried on the back frame 241. The back frame 241 is accommodated in the housing 240. Figure 3 and Figure 4 Afterwards, it can be clearly seen that due to Figure 3The vehicle-mounted display device 100 does not have a back frame 241, so the side wall thickness of the back frame 241 (i.e., distance D1) and the lateral gap between the back frame 241 and the housing 240 (i.e., distance D2) can be reduced in the width direction of the vehicle-mounted display device 100, so that the vehicle-mounted display device 100 can effectively reduce the overall width to achieve the purpose of narrow frame. In addition, the bottom plate thickness of the back frame 241 (i.e., distance D3) and the longitudinal gap between the back frame 241 and the housing 240 (i.e., distance D4) can be reduced in the thickness direction of the vehicle-mounted display device 100, so that the overall thickness of the vehicle-mounted display device 100 can be effectively reduced to achieve the purpose of thinning.

[0073] From the above detailed description of the specific implementation of the present disclosure, it can be clearly seen that in the vehicle-mounted display device disclosed herein, the cover plate, the display module and the frameless backlight module are fixed in the accommodation space of the integrated housing, so the overall width and thickness of the vehicle-mounted display device can be effectively reduced. By arranging the main circuit board on the back of the housing (that is, outside the accommodation space) and allowing the display module's cable to pass through the housing and connect to the main circuit board, the overall thickness of the vehicle-mounted display device can be further reduced. The mounting frame covering the back of the housing can achieve the purpose of hiding the main circuit board and the cable.

[0074] Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the definition of the attached claims.
