Abstract

Television receiver has at least one planar or wire antenna (5) for the receipt of terrestrial, analogue or digital, television and radio signals. The at least one antenna (5) is attached to the inner or outer side of the filter screen (2) or the inner or outer side of the housing rear wall (3). An internal connection (6) is made if the antenna is inside. If outside, a connection (4) is made to the internal connection.

Description

  • The invention relates to a television receiver with a Casing, a front filter disc and at least one rear wall and a receiving circuit for Terrestrially distributed digital or analog television and audio broadcast signals with a connection to at least one receiving antenna.
  • From the DE 200 00 921 U a high-frequency transmission and / or reception circuit for audio and / or video and / or data or control signals for communication between at least two electronic reception, recording or reproduction devices of such signals and / or a remote control transmitter is known for this purpose, which transmission and / or receiving circuit is connected to an antenna. The transmitting and / or receiving circuit is integrated in the housing of the receiving, recording or reproducing device. The antenna for transmitting the signals is formed from the metal parts of the chassis and / or metal fasteners in or on the housing or from metal parts of a base frame, which metal parts are present in the chassis or in the device or in the base frame of the device for other purposes anyway. Contact connections for connecting to the transmitting and / or receiving circuit are provided on the parts.
  • It is also out of the DE 197 331 A1 a radio device with a housing is known, the housing comprising a hearing device on one side and an antenna element on a second side opposite the first side. The antenna element is movably mounted on a second side of the housing and has a directional radiation characteristic at least in a first position and an omnidirectional radiation characteristic in at least a second position. The antenna is attached to the back on the outside or inside.
  • From the DE 198 15 322 a reflector antenna for analog and digital mobile telephones is also known. The reflector can be designed planar or convex to broaden the antenna pattern. The base of the antenna is designed as a conductive level. In a user-friendly version, the rod antenna can be integrated in the fastening clip of the mobile radio device. In the DE 689 10 184 T2 a 2-antenna is also shown, which is housed in a housing.
  • Currently, for the portals, digital, terrestrial television reception passive or active antennas available, the nearer Environment of the TV set set up and over a coaxial cable can be connected externally. These antennas are either in conventional Dipole technology or manufactured in planar technology. With such antennas Is it possible, both terrestrial digital and analog TV signals to recieve.
  • For DVB-T reception there are also small indoor antennas in the area of the television or can be set up separately. The reception performance is enough to get the over the filling transmitter fed TV channels to be able to receive in the digital band.
  • It has been shown that integration of antennas in the chassis itself is extremely difficult and planar antennas due to the space requirement and the ability to arrange them do not work optimally if they are not installed stationary. on the other hand the adjacent antennas are a hindrance since they are reserved for other purposes Footprints or Accessory rooms available to take.
  • The invention is based on the object a generic object so that an antenna, in particular for receiving terrestrial DVB-T signals, into which the device can be installed.
  • The invention solves the problem by design the television receiver according to the in the claim 1 specified technical teaching.
  • Advantageous further developments of Invention and the arrangement and designs of the antenna are in the subclaims specified.
  • By attaching the antenna, especially a planar antenna, either on or behind the windscreen or on the back wall the immediate interference of the electronic circuits of the flat panel display or picture tube the circuit largely eliminated or reduced. Furthermore is an integral solution possible, so that additional connections for one outside aerial on such devices need not be provided. This has particular advantage in portable flat display devices. In these can according to the teaching the invention, the antennas either in or on the windshield or in or on the back wall of the device be provided. A planar antenna has proven to be particularly advantageous proven that is manufactured using film technology and glued flat can. Instead of the foil technology, the antenna can also be used the plastic back wall inside or outside be evaporated. It is also possible to use an antenna while injecting or in a tool before spraying the plastic and have it overmolded so that the antenna is fully protected and only the electrical lead wire protrudes to one Is struck to make the appropriate connection with the To be able to manufacture tuners.
  • In accordance with the reception conditions and to ensure reception in all set-up positions, it is also appropriate to provide at least one further antenna in the device instead of a single antenna, in particular a planar antenna. This can be done in such a way that these are horizontally and vertically offset from one another either on the inside or outside on the rear wall or on the inside or on the front screen can be introduced into this. However, it is also possible to provide a single antenna on the front pane and an antenna offset from it on the rear wall. If two plates glued together are used as the front pane or filter pane, the planar antenna can also be integrated between the panes. It can also be evaporated at this point so that it is practically transparent. The connection cable is then only to be brought out in order to be able to establish the connection to the tuner.
  • The arrangement of the antenna also has the advantage that shielding structures can also be introduced in a simple manner can be. For example, it is possible also to shield an antenna towards the chassis side, so that from no interference from the antenna itself emanates.
  • The invention is illustrated below with reference to the drawings 1 . 2 . 3 and 4 additionally explained.
  • 1 shows a schematic representation of the filter disk or the projection screen of a rear projection device or a display device. On the inside of this disc 2 is a polarization and direction independent VHF / UHF antenna 5 for the reception of terrestrial, analog and digital television signals applied. It can be, for example, a film antenna that is glued on. However, it is also possible by means of metallization to evaporate the structure, the dipole antenna shown being considered as an example. The person skilled in the art has a wide variety of training options for the antenna here in accordance with the requirements, in particular the requirements also for the reception of digital signals, such as DVB-T signals. However, the antenna can also be integrated into the base material itself, that is to say overmolded or inserted between the two layers in the case of layer disks. 1 shows a single antenna 5 that have a connector 6 with a connector 4 is coupled, which is attached to the input of the tuner during final assembly.
  • 2 shows an arrangement in which two antennas in the vertical direction 5 are provided one above the other on the windscreen. The supply lines are also here 6 with the connectors 4 inside the case 1 routed so that the desired connection can be made with the tuner. It is also possible to use the connectors 4 to couple with a diversity circuit so that only the receiving antenna with the best reception properties is selected in order to be able to be connected to the tuner. With the flat display devices, which in 1 and 2 is shown, a rear wall is provided in each case.
  • 3 and 4 show another example, the rear wall 3 is now drawn to the foreground and hatched. On the inside of the back wall or in the back wall itself there is how 3 shows an antenna introduced. In 4 are two antennas 5 shown, which are offset from each other. Here, too, the electrical connection to the antenna is made via the respective connection lines 6 and connectors 4 made with the tuners. This arrangement also has the advantage that when a television set is set up, for example in the area of the outer wall of a building, and the filling transmitter shines in directly, optimal reception is ensured without any structural changes and attachment of external antennas. In addition, these antennas can be integrated into the manufacturing process, so that no further expenditure is incurred and reception is ensured without the use of antenna connection cables.
