The present invention also provides a kind of means of transport of optionally motor type, the means of transport is included at least one
State the electronic equipment of type.
Description of the drawings
By reading following detailed description and drawings, other features and advantages of the present invention will become apparent from, described attached
In figure：
- Fig. 1 is schematic and functionally illustrates an exemplary part for the motor vehicle including electronic equipment, institute
State electronic equipment include display device according to the present invention and
- Fig. 2 is schematic and functionally illustrates the embodiment of the electronic equipment including display device according to the present invention
Rearview.
Specific embodiment
In particular, in that providing a kind of display device DA, the display device is used for as including that can connect the purpose of the present invention
Receive a part of the electronic equipment EE of the antenna AR of radio wave.
Hereinafter, as non-limiting example, it is believed that electronic equipment EE is the radio set for vehicle of means of transport V.But this
Invention is not limited to the electronic equipment of the type.The electronic equipment is in fact related to the antenna for including that radio wave can be received
Any kind of electronic equipment.Therefore, the electronic equipment further relates to the radio of such as radio station, high-fidelity channel and connects
Receive amplifier-tuner of device (or " tuner ") and high-fidelity channel.
In addition, hereinafter, as non-limiting example, it is believed that means of transport V is motor type.The means of transport
E.g. car.But electronic equipment EE can be as the one of the means of transport of any types (land, marine (or on river) or aerial)
Part.In addition, electronic equipment EE also can temporarily or permanently be installed between floors, the building is optionally industrial type
's.
It is exemplary one schematic and functionally illustrating the motor vehicle V including electronic equipment EE on Fig. 1
Point, the electronic equipment includes display device DA according to the present invention.The electronic equipment EE (herein, radio set for vehicle) is more really
It is mounted in the instrument board PB of means of transport V with cutting, the instrument board is itself mounted in the cockpit H of the means of transport V.
Although not complete on Fig. 1 and 2 occur, electronic equipment EE includes the control unit of receiving part and electronic type,
The receiving part especially includes that the antenna AR of radio wave and the Signal Processing Element of electronic type can be received.
As shown in Figure 2, display device DA according to the present invention include be provided with the touch screen ET of printed circuit board CC with
And conducting wire FC.
Printed circuit board (PCB (" Printed Circuit Board ")) CC controls display unit (for example, touching tablet)
And emit electromagnetic wave at runtime.In the case of touch screen ET, the electromagnetic wave is periodic and for example per 33MHz
Ground includes harmonic wave.
Conducting wire FC includes being coupled the first end and free second of (for example, connection) with the ground terminal of printed circuit board CC
End.In addition, placements (see Fig. 2) of the conducting wire FC in touch screen ET behinds can be captured by the touch screen ET electromagnetic waves generated
At least part in energy.Therefore, conducting wire FC is used as mating antenna, and the mating antenna can reduce to be drawn by the electromagnetic wave
The electromagnetic interference risen.
Since one in the opposite end of the conducting wire is free, conducting wire FC is formed a kind of " short-term ", described short
Line can capture at least part in the energy of the electromagnetic wave generated in the short-term side.Therefore, the energy through capture
Part no longer reaches the position of the reception antenna AR of electronic equipment EE, this can be substantially reduced at reception antenna AR positions
Interference, and therefore can avoid reducing the audio quality of the program played by selected radio station.
The physical property of conducting wire FC is similar to the performance of reception antenna, but also with (known in electronic circuit field) short-term
Performance it is similar, this is because conducting wire FC is attached on one end in the both ends of conducting wire, the second end in the both ends is in sky
In gas.
For example, conducting wire FC can be made of copper or aluminium or any other known conductive material.
Further for example, the diameter that conducting wire FC has can be between 1mm and 4mm.The selection to value is the resistance by conducting wire
The fact that be inversely proportional with the diameter of the conducting wire and obtain.It is highly preferred that the diameter can be between 1.5mm and 3mm.
Further for example, the length that conducting wire FC has can be in 30cm between 70cm.The selection to value is the electricity by conducting wire
It hinders the fact that directly proportional to the length of the resistivity of the conducting wire and the conducting wire and obtains.The length of the conducting wire also has and biography
The directly related larger importance of the wavelength of the electromagnetic wave broadcast.It is highly preferred that the length can be between 40cm and 50cm.
Further for example, as shown in nonrestrictive on Fig. 2, conducting wire FC can be connect with the grounding pin of connector CN, the connection
Device is connected with printed circuit board CC.As an example, when printed circuit board CC is disposed with company well known by persons skilled in the art
It meets device J6 and (is exclusively used in and is loaded in LIN (" the Local Interconnect Network (local internets in means of transport V
Network) ") the multiplex communication network link of type) when, the first end of conducting wire FC can be with the ground connection that is exclusively used in of connector J6
Third pin connects.
It is noted that as shown in nonrestrictive on Fig. 2, conducting wire FC can be at least partly as a part of wirning harness FE, institute
Stating wirning harness ensures coupling, such as (optionally more between the connector CN of touch screen ET and another equipment of means of transport V
Road multiplexing) bus of communication network.
Herein " as ... a part " be understood as being integrated in inside wirning harness FE or follow at least partly with should
The identical path in the path of wirning harness FE.
It is noted that when printed circuit board CC is disposed with connector J6 and connector J5 (is exclusively used in and is loaded in haulagman
Has the multiplex communication network connection of CAN (" Controller Area Network (controller local area network) ") type in V
Knot) when, the ground connection being present between LIN networks and the ground terminal of CAN network splices the disconnection energy of (é pissure de masse)
Conducting wire FC is enough made to be in air, and therefore can realize the desired effect for reducing electromagnetic interference.
