Abstract

Display device which will be considerably flatter by contacting conductor tracks on one side of a substrate via connectors with conductor parts contacting the conductor tracks around the edge of the substrate with contact faces on the other side of the substrate. These contact faces extend parallel to the substrate and may directly or indirectly contact conductor tracks on, for example a printed circuit board.

Claims

1. A display device comprising a first and a second substrate with an electro-optical material between the two substrates each being provided with picture electrodes defining pixels with the intermediate electro-optical material, the first substrate being provided beyond its part located opposite the second substrate with connection conductors extending as far as an edge of the first substrate, characterized in that, at the area of said edge, the display device has a connector housing which embraces the edge and comprises a plurality of conductor parts which, viewed in the direction of the edge, are U-shaped and connect each connection conductor in an electrically conducting manner to an associated contact face which is substantially parallel to the first substrate and is located on the side of the connector housing remote from the second substrate, there being a contact paste applied between the conductor parts and corresponding connection conductors, and the face of the connector housing located against the first substrate at the side of the picture electrodes being provided with depressions between the conductor parts to prevent smearing of the contact paste between adjacent conductor parts.

2. A display device comprising a first and a second substrate with an electro-optical material between the two substrates each being provided with picture electrodes defining pixels with the intermediate electro-optical material, the first substrate being provided beyond its part located opposite the second substrate with connection conductors extending as far as an edge of the first substrate and being connected in an electrically conducting manner to connection tracks on a support, characterized in that, at the area of said edge, the display device has a connector housing which embraces the edge and comprises a plurality of conductor parts which, viewed in the direction of the edge, are U-shaped and connect each connection conductor in an electrically conducting manner to an associated contact face which is substantially parallel to the first substrate and is located on the side of the connector housing remote from the second substrate, said contact face being connected in an electrically conducting manner to at least a connection track on the support, there being a contact paste applied between the conductor parts and corresponding connection conductors, and the face of the connector housing located against the first substrate at the side of the picture electrodes being provided with depressions between the conductor parts to prevent smearing of the contact paste between adjacent conductor parts.

3. A display device comprising a first and a second substrate with an electro-optical material between the two substrates each being provided with picture electrodes defining pixels with the intermediate electro-optical material, the first substrate being provided beyond its part located opposite the second substrate with connection conductors extending as far as an edge of the first substrate, characterized in that, at the area of said edge, the display device has a connector housing comprising a plurality of conductor parts which, viewed in the direction of the edge, partly embrace said edge and connect each connection conductor in an electrically conducting manner to an associated contact face which is substantially parallel to the first substrate and is located on the side of the connector housing remote from the second substrate, there being a contact paste applied between the conductor parts and corresponding connection conductors, and the face of the connector housing located against the first substrate at the side of the picture electrodes being provided with depressions between the conductor parts to prevent smearing of the contact paste between adjacent conductor parts.

4. A display device comprising a first and a second substrate with an electro-optical material between the two substrates each being provided with picture electrodes defining pixels with the intermediate electro-optical material, the first substrate being provided beyond its part located opposite the second substrate with connection conductors extending as far as an edge of the first substrate and being connected in an electrically conducting manner to connection tracks on a support, characterized in that, at the area of said edge, the display device has a connector housing comprising a plurality of conductor parts which, viewed in the direction of the edge, partly embrace said edge and connect each connection conductor in an electrically conducting manner to an associated contact face which is substantially parallel to the first substrate and is located on the side of the connector housing remote from the second substrate, said contact face being connected in an electrically conducting manner to at least a connection track on the support, there being a contact paste applied between the conductor parts and corresponding connection conductors, and the face of the connector housing located against the first substrate at the side of the picture electrodes being provided with depressions between the conductor parts to prevent smearing of the contact paste between adjacent conductor parts.
