This invention will be better understood by referring to the accompanying drawings, wherein:
A first preferred embodiment of a television module 4 provided with an antenna on its PC board in the present invention, as shown in
The PC board 10 is for receiving the IC of the foresaid units thereon.
The antenna unit 20 is a printed circuit antenna 21 formed by printing copper foil on the PC board 10. The printed circuit antenna 21 could be in a bent shape, a labyrinth shape, a Z shape or a whirlpool shape. The antenna unit 20 could also be a micro-antenna 22 secured on the PC board 10. The antenna unit 20 of this preferred embodiment is a bent-shaped printed circuit antenna 21.
The modulation unit 30 properly fixed on the PC board 10 consists of a wave filtering-and-amplifying circuit 31, a tuner 32 and a decoding-modulating device 33. The tuner 32 for modulating different received frequencies has one end connected with the antenna unit 20 by the wave filtering-and-amplifying circuit 31 and the other end connected with the decoding-modulating device 33. The decoding-modulating device 33 could be a specification of DVB-T (Digital Video Broadcasting Television), DVB-H (Digital Video Broadcasting Handhelds), ISDB (Integrated Services Digital Broadcasting) or ATSC (Advanced Television System Committee). The decoding-modulating device 33 of this preferred embodiment is a specification of DVB-T. Both the decoding-modulating device 33 and the tuner 32 are together connected with an automatic gain controller 34.
The digital image-processing unit 40 consists of a multipoint control unit (MCU) 41, a power circuit 42 and an image driving-and-processing circuit 43. The multipoint control unit 41 has one end connected with the modulation unit 30 and the other end connected with an image display 50 by image driving-and-processing circuit 43. The image display 50 of this preferred embodiment is a liquid crystal display. The power circuit 42 is connected with the multipoint control unit 41 for supplying various voltage modes needed by the television module 4. The multipoint control unit 41 could be connected with an external data reading device 60. The external data-reading device 60 of this preferred embodiment is an IC card reader.
In using, as shown in
A second preferred embodiment of a television module provided with an antenna on its PC board in the present invention, as shown in
As can be understood from the above description, this invention has the following advantages.
1. The antenna of the television module of this invention is not an external antenna but a printed circuit antenna formed by printing copper foil on the PC board, saving space for assembling the antenna unit.
2. The television module and the driving circuit of the image display can be assembled together on the same PC board to make up a single module, needless to take space for the antenna unit and conducive to miniaturization of electronic products.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
