Description

[0001] The present disclosure relates to a display device for a vehicle according to the preamble of claim 1. The present disclosure also relates to a vehicle with such a display device.

[0002] Display units are used in a vehicle to show, for example, the vehicle's surroundings. These display units are bulky because several internal components, such as electronic control units (ECUs), are stacked on top of each other to form a single display unit. The ECUs are also arranged in various specialized housings and on different horizontal planes.

[0003] Electromagnetic radiation is generated by electronic components such as ECUs. This electromagnetic radiation causes many performance problems and increases significantly when a device has two or more ECUs.

[0004] Therefore, electromagnetic shielding, especially electromagnetic coupling shielding (EMC shielding), is stacked on top of each other in various horizontal planes to minimize electromagnetic interference. This electromagnetic shielding increases the number of components in the display device, extending assembly time during manufacturing and increasing the overall size of the assembly.

[0005] A well-known prior art document, EP 4 164 922 A2 (WO 2022 / 034 240 A2), relates to a vehicle display system and a vehicle display mounting device. The vehicle display mounting device comprises a display unit attached to a display frame and connected to a handle, and an intermediate adapter coupled to the handle. The intermediate adapter includes a mounting arm for attachment to a vehicle at a first mounting point, a retaining strap coupled to the mounting arm and the vehicle at the first mounting point, and a mounting component coupled to the intermediate adapter. The control units in this vehicle display have separate housings in different vertical planes, which is why the vehicle display is bulky due to space constraints and difficult to install in the vehicle.Furthermore, it is difficult to completely shield the control units of these vehicle display systems from electromagnetic radiation using EMC shielding units or plates. Therefore, complete protection against electrical and magnetic interference is not possible. Additionally, the EMC shields are also stacked vertically, making the vehicle display even bulkier or thicker.

[0006] Another known prior art, US 10,499,517 B2, relates to a display device for a motor vehicle, comprising a housing with a front opening, a circumferential wall, and a rear wall arranged along a principal axis. The housing is configured to accommodate a display module on the side of the front opening and a printed circuit board (PCB) connected to the display module. The PCB includes an electronic control unit for controlling the display module, with an inner housing mounted in the housing on the rear wall of the housing. The inner housing comprises a first mounting surface for receiving the PCB and a second mounting surface for receiving the display module. The housing includes a first set of axial retaining elements that hold the PCB on the first mounting surface and a second set of axial retaining elements that hold the display module on the second mounting surface.

[0007] Another known prior art, EP 3 944 010 A1, relates to a display device for an imaging instrument comprising a display panel, a display, a first control unit, a second control unit, a heat-insulating layer, and a housing. The heat-insulating layer divides the housing into at least a first cavity, which comprises the first control unit, and a second cavity, which comprises the second control unit. The heat-insulating layer prevents the heat generated in the first or second cavity from reaching the other cavity and comprises an electrically conductive material to at least partially prevent the electromagnetic radiation generated in the first or second cavity from reaching the other cavity.

In yet another embodiment, the heat sink 250 can be made of a conductive material such as aluminum or copper. The display unit 200 can be configured such that the heat sink 250 remains in contact with the display holder 206. In such a scenario, the display holder 206, which is inherently conductive, can also act as a heat dissipation unit. This is an additional advantage of the current design, in which the display holder 206 also serves as an EMC shield and heat dissipation unit.

[0057] The display device 200 according to the embodiment of the Fig. 3B and Fig. 4 further comprises a first EMC sealing unit 210, which is arranged between the unit 208 and the backlight cover 204, and a second EMC sealing unit 212, which is arranged between the control unit 208 and the display holder 206. In one embodiment, the display holder 206 and the backlight cover 204 are configured to form a closed housing to accommodate the control unit 208 and / or the PCB 214. This closed housing ensures the EMC sealing of the control units 208 and / or the electronic components arranged on the PCB 214. Here, the housing is designed as a Faraday cage in which the control unit 208 and / or the electronic components arranged on the PCB 214 are shielded from all external electrical and magnetic radiation.The first EMC sealing unit 210 and the second EMC sealing unit 212 further ensure that electromagnetic radiation does not escape to the outside of the housing or inwards from within the housing. It is generally known that the Faraday cage serves to reduce the electromagnetic radiation emitted by an electronic assembly. It is also generally known that the Faraday cage is an enclosure used to shield against electromagnetic fields.

[0058] In one embodiment of the present disclosure, the display device 200 is further configured to prevent at least some electromagnetic radiation generated in the first recording section 300a from reaching the second recording section 300b; and to prevent at least some electromagnetic radiation generated in the second recording section 300b from reaching the first recording section 300a.

[0059] In one embodiment, the at least two EMC sealing units 210, 212 are conductive. For example, the at least two EMC sealing units 210, 212 are made of copper, aluminum, or alloys thereof. In another embodiment, the at least two EMC sealing units 210, 212 are formed in the display device 200 using a form-in-place (FIP) technology. FIP technology refers to the application of a liquid or moldable sealing element to metal or plastic parts before the device is assembled. With FIP technology, the sealing element is applied as a liquid or mold so that it conforms precisely to the shape or form of the part, regardless of surface irregularities. This results in a reliable EMC seal and longevity of the display device 200.In one embodiment, FIP sealing units are applied using known computer-controlled numerical control (CNC) machines. In the context of the present disclosure, CNC can be defined as a manufacturing process that automates the control, movement, and precision of machine tools using pre-programmed computer software embedded in the tools. Furthermore, the FIP process is so precise that even surfaces less than one millimeter wide can be provided with FIP sealing elements. The FIP sealing units are cost-effective, accurate, and offer a simple sealing solution, particularly in cases where a very small, narrow, or complex seal is required.In another embodiment, the at least two EMC sealing units 210, 212 are manufactured using a printing process, a CNC machining process or a combination thereof.

[0060] With reference to Fig. 4. A connector 302 can be connected to the second PCB 214b to establish a data or electrical connection from the vehicle 100 (in particular, a battery of the vehicle) to the display unit 200. Depending on the design of the display unit 200, the connector 302 can also be connected to the first PCB 214a. In one embodiment, an opening can be provided in a housing 216 to allow a cable of the connector 302 to exit. Furthermore, a connection can be established between the housing 216 and the panel 220 using a sealant, adhesive tape 304, or the like.
