[0033] Currently, displays occupy a large space and have many parts, making assembly quite complex, which is not conducive to reducing the production cost of displays.
[0034] Based on this, this application proposes a display assembly 100, an instrument panel assembly, and a vehicle. The PCB board 2 in the display assembly 100 integrates an input connector 21, a power module 22, a serializer module 23, a touch display module 24, a controller 25, and an output connector 26, which greatly improves the integration level of the PCB board 2 and helps to reduce the space occupied by the display assembly 100. Furthermore, the PCB board 2 is directly connected to the display module 1 through a flexible circuit board 3, which reduces assembly steps and helps to reduce production costs.
[0035] The following description, with reference to the accompanying drawings, illustrates an embodiment of the display assembly 100, a dashboard assembly, and a vehicle.
[0036] like Figures 1-2 As shown, the display assembly 100 according to the first aspect of this application includes: a display module 1, a PCB board 2, and a flexible circuit board 3.
[0037] It should be noted that the current display assembly 100 typically includes a T-Con (Timing Controller 25) and a PCB (Printed Circuit Board). The T-Con is equipped with a touch display module 24, which is mainly responsible for controlling the timing signals and image processing of the screen. For example, it receives video signals from the motherboard and converts them into timing signals required by the display module 1, and precisely controls the scanning timing of the display module 1. The PCB is mainly used to fix electronic components and realize electrical connections through conductive paths.
[0038] However, currently the T-Con and PCB are set on two different board structures and connected by a conversion circuit. This results in a large space occupation for the display assembly, which is not conducive to the external shape design of the screen. In addition, the connection between the T-Con and the PCB increases the assembly process, making the assembly more complicated and also hindering the reduction of display production costs.
[0039] Based on this, the functional components in T-Con are integrated onto PCB board 2, thereby simplifying the display assembly 100 into three components: display module 1, PCB board 2, and flexible circuit board 3, thus reducing assembly steps and helping to reduce production costs.
[0040] Specifically, PCB board 2 is fixedly mounted to display module 1, and the mounting methods include, but are not limited to, bolt connection, snap-fit, etc. For example... Figure 2 As shown, PCB board 2 includes an input connector 21, a power module 22, a serializer module 23, a touch display module 24, a controller 25, and an output connector 26. The input connector 21 can be configured as an HSD connector. In this application, the display assembly 100 is used in a vehicle for illustration. The HSD connector is connected to the vehicle's host computer. The vehicle's host computer supplies power to PCB board 2 and transmits video signals through the HSD connector.
[0041] Furthermore, the input connector 21 (HSD connector) is electrically connected to the power module 22. Thus, external power is first delivered to the power module 22 through the HSD connector. The power module 22 is also electrically connected to the serializer module 23, the touch display module 24, the controller 25, and the output connector 26. In this way, the power module 22 can provide separate power to different functional devices. For example, if the serializer module 23, the touch display module 24, the controller 25, and the output connector 26 have different operating voltages, the power module 22 can supply power to the serializer module 23, the touch display module 24, the controller 25, and the output connector 26 separately, which can meet the power supply requirements of different functional devices. It can also achieve precise control of the power supply voltage of different functional devices, avoiding the risk of overvoltage or undervoltage of functional devices.
[0042] Furthermore, such as Figure 2 As shown, the input connector 21 is also communicatively connected to the serializer module 23. The input connector 21 (HSD connector) is used to receive video signals from the vehicle's main unit. After receiving the video signal, the input connector 21 transmits the video signal to the serializer module 23. The serializer module 23 then converts the received video signal into a high-speed serial signal. The serializer module 23 is communicatively connected to the touch display module 24. The serializer module 23 transmits the generated high-speed serial signal to the touch display module 24. The touch display module 24 decodes the received high-speed serial signal into row and column drive signals. The touch display module 24 is communicatively connected to the output connector 26, thereby enabling the row and column drive signals to be sent to the output connector 26. The flexible circuit board 3 is connected between the output connector 26 and the display module 1. It can be understood that the power module 22 provides the operating voltage to the output connector 26. In this way, the row and column drive signals can be transmitted to the display module 1 through the flexible circuit board 3. The display module 1 then precisely controls the pixel display according to the row and column drive signals, thereby realizing the display function of the display module 1.
[0043] It should be noted that the controller 25 is also communicatively connected to the serializer module 23 and the touch display module 24. Thus, the controller 25 can send central control signals to the serializer module 23 and the touch display module 24 respectively to adjust the brightness, color, and other functions of the display module 1. When an operator touches the display module 1, the touch display module 24 sends a touch signal to the controller 25. The controller 25 then feeds back the touch signal to the vehicle's main unit sequentially through the serializer module 23 and the input connector 21 (HSD connector) to provide touch feedback to the display module 1. For example, when the operator slides left on the display module 1... The touch display module 24 forwards the leftward sliding signal to the vehicle host via the controller 25. Then, the vehicle host issues a leftward page-turning video signal based on the leftward sliding touch signal. After receiving the leftward page-turning video signal, the input connector 21 sends it to the serializer module 23. The serializer module 23 then regenerates a high-speed serial signal based on the leftward page-turning video signal. The touch display module 24 decodes the new row and column drive signals based on the regenerated high-speed serial signal. The display module 1 refreshes the pixels based on the new row and column drive signals to display the leftward page-turning video, thereby realizing the touch adjustment display function of the display module 1.
[0044] It can be seen that the touch display module 24 in this application is equivalent to disassembling and integrating the traditional T-Con touch display device onto the PCB board 2, eliminating the need for a separate T-Con board, which greatly improves the integration level of the PCB board 2. Compared with the traditional display assembly 100, it has one less component inside, which helps to reduce the space occupied by the display assembly 100. In addition, the PCB board 2 is directly connected to the display module 1 through the flexible circuit board 3, which reduces the assembly process and helps to reduce production costs.
[0045] In some embodiments of this application, such as Figure 2 As shown, the power module 22 includes a main power module 221 and a serializer power module 222. The input connector 21 is electrically connected to the main power module 221. The main power module 221 is electrically connected to the serializer module 23 and the serializer power module 222 respectively. The serializer power module 222 is also electrically connected to the serializer module 23. In other words, the input connector 21 (HSD connector) is directly electrically connected to the main power module 221 in the power module 22. Thus, external power is first delivered to the main power module 221 through the HSD connector. It can be understood that the serializer module 23 has two sub-modules with different operating voltages. The main power module 221 is electrically connected to the serializer module 23 to directly power one of the sub-modules, while the other sub-module in the serializer module 23 is powered through the serializer power module 222, which in turn is powered through the main power module 221. Thus, the combined use of the main power module 221 and the serializer power module 222 meets the power supply requirements of different sub-modules in the serializer module 23, making it easier to accurately control the power supply voltage of different sub-modules.
[0046] In some embodiments of this application, such as Figure 2 As shown, the power module 22 also includes a touch display power module 223, which is electrically connected to the main power module 221 and to the touch display module 24. In other words, the main power module 221 supplies power to the touch display power module 223, which in turn provides the touch display module 24 with the voltage required for operation. This configuration allows the touch display power module 223 to provide more precise voltage control for the touch display module 24.
[0047] In some embodiments of this application, such as Figure 2 As shown, it also includes: a backlight strip 4, a PCB board 2 also includes a backlight control module 27, an input connector 21 is electrically connected to the backlight control module 27, and the backlight control module 27 is electrically connected to the backlight strip 4.
[0048] Specifically, for the display assembly 100 with backlight strip 4, the traditional display assembly 100 places the backlight control module 27 on the T-Con. However, in this application, the backlight control module 27 of the traditional T-Con is separated and integrated onto the PCB board 2. This further realizes the integration function of the PCB. The backlight control module 27 is electrically connected to the input connector 21 (HSD connector), so that the input connector 21 (HSD connector) can deliver external power to the backlight control module 27. The backlight control module 27 is electrically connected to the backlight strip 4. That is to say, the power supply and control of the backlight strip 4 are realized through the backlight control module 27, such as controlling the brightness of the backlight strip 4.
[0049] It should be noted that the backlight strip 4 is fixedly installed on the display module 1. For example, the backlight strip 4 is designed to surround the periphery of the display module 1. The installation method includes, but is not limited to, snap-fit and glued.
[0050] In some embodiments of this application, the flexible circuit board 3 is snap-fitted to the output connector 26. That is, one end of the flexible circuit board 3 and the output connector 26 can be fixed by a snap-fit connection. For example, the flexible circuit board 3 has a slot structure, and the output connector 26 has a snap-fit structure that matches the slot structure. When the flexible circuit board 3 and the output connector 26 are assembled, the snap-fit structure and the slot structure are snapped together. Alternatively, the flexible circuit board 3 has a first connection pin, and the output connector 26 has a second connection pin that matches the first connection pin. The first connection pin and the second connection pin can be snap-fitted together and fixed. Of course, other snap-fit structures can also be used in this application, and no specific limitations are made here.
[0051] In some embodiments of this application, the flexible circuit board 3 is crimped to the connection end of the display module 1. That is, the other end of the flexible circuit board 3 is fixed to the connection end of the display module 1 by crimping. The crimping method includes, but is not limited to, mechanical crimping, thermal crimping, etc. The crimping method can improve the connection strength between the connection end of the flexible circuit board 3 and the display module 1, thereby improving the stability of the display assembly 100.
[0052] In some embodiments of this application, the connection end between the flexible circuit board 3 and the display module 1 is bonded with adhesive. That is, the other end of the flexible circuit board 3 and the connection end of the display module 1 can also be fixed with adhesive. This connection method is relatively simple and reliable, and also helps to save costs.
[0053] In some embodiments of this application, such as Figure 1As shown, the flexible circuit board 3 is at least partially fixed between the display module 1 and the PCB board 2. Specifically, the PCB board 2 is provided with clearance holes. The input connector 21, power module 22, serializer module 23, touch display module 24, controller 25, output connector 26, and backlight control module 27 are all located on the side of the PCB board 2 away from the display module 1. The flexible circuit board 3 is partially sandwiched between the display module 1 and the PCB board 2, with one end of the flexible circuit board 3 passing through the clearance hole to engage with the output connector 26, and the other end of the flexible circuit board 3 connected to the display module 1. This arrangement ensures the stable installation of the flexible circuit board 3 and prevents interference between the flexible circuit board 3 and the functional components on the PCB board 2, thereby ensuring the performance of the display assembly 100.
[0054] Secondly, embodiments of this application provide an instrument panel assembly, including the display screen assembly 100 in the first aspect embodiment.
[0055] According to the second aspect of the present application, the instrument panel assembly is provided with the above-mentioned display screen assembly 100. The PCB board 2 of the display screen assembly 100 integrates an input connector 21, a power module 22, a serializer module 23, a touch display module 24, a controller 25, and an output connector 26, which greatly improves the integration level of the PCB board 2 and helps to reduce the space occupied by the display screen assembly 100. In addition, the PCB board 2 is directly connected to the display module 1 through the flexible circuit board 3, which reduces the assembly process and helps to reduce production costs.
[0056] Thirdly, embodiments of this application provide a vehicle including the dashboard assembly described in the second aspect embodiment.
[0057] According to the vehicle proposed in the third aspect of this application, by providing the above-mentioned instrument panel assembly, the PCB board 2 of the display assembly 100 integrates an input connector 21, a power module 22, a serializer module 23, a touch display module 24, a controller 25, and an output connector 26, which greatly improves the integration level of the PCB board 2, helps to reduce the space occupied by the display assembly 100, and the PCB board 2 is directly connected to the display module 1 through the flexible circuit board 3, which reduces the assembly process and helps to reduce production costs.
[0058] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Each embodiment focuses on describing the differences from other embodiments.
