Abstract

An electronic device according to various embodiments of the present disclosure may include: a housing having first and second faces opposite to each other; a transparent substrate disposed on the first face of the housing; a display panel disposed below the transparent substrate; and an input sensing panel disposed below the display panel. The input sensing panel may include: a plurality of conductive patterns; and dummy patterns each disposed between each of the conductive patterns. Other various embodiments are also possible.

First claim

1 . An electronic device comprising:
a housing having first and second faces opposite to each other; a transparent substrate disposed on the first face of the housing; a display panel disposed below the transparent substrate; and an input sensing panel disposed below the display panel, wherein the input sensing panel comprises:
a plurality of conductive patterns; and
dummy patterns each disposed between each of the conductive patterns.

2 . The electronic device of claim 1 , wherein the dummy patterns are constructed of a non-conductive material.

3 . The electronic device of claim 1 , wherein each of the dummy patterns is constructed to have substantially the same thickness as that of each of the conductive patterns,
wherein each of the dummy patterns is disposed to be co-planar with each of the conductive patterns.

4 . The electronic device of claim 1 , wherein the transparent substrate is constructed of a synthetic resin material.

5 . The electronic device of claim 1 , wherein the plurality of conductive patterns comprise:
transmission patterns disposed with an equal interval, and each extended in a first direction; and reception patterns disposed with an equal interval, and each extended in a second direction different to the first direction, wherein the dummy patterns comprise:
at least one or more transmission dummy patterns each constructed between each of the transmission patterns; and
at least one or more reception dummy patterns each constructed between each of the reception patterns.

6 . The electronic device of claim 5 , wherein the transmission dummy patterns and the reception dummy patterns are disposed in directions crossing each other, while overlapping with each other.

7 . The electronic device of claim 1 , wherein the display panel comprises a touch screen display panel, the touch screen display panel comprising:
a flat touch screen display; and a curved touch screen display disposed to an edge of the flat touch screen display, wherein when the touch screen display panel is viewed from above, a first region having the flat touch screen display disposed thereon has a dummy pattern constructed between each of the conductive patterns, and a second region having the curved touch screen display disposed thereon does not have a dummy pattern constructed between each of the conductive patterns.

8 . The electronic device of claim 7 , wherein the touch screen display panel comprises any one of a Liquid Crystal Display (LCD) display panel and an Organic Light Emitting Diode (OLED) display panel,
wherein the input sensing panel is a digitizer, the digitizer comprising:
a digitizer flexible circuit;
at least one or more conductive patterns constructed on the digitizer flexible circuit; and
a non-conductive pattern disposed between each of the conductive patterns.

9 . An electronic device comprising:
a transparent substrate constructed of a synthetic resin material; a display panel disposed to a lower face of the transparent substrate and having first and second faces facing each other; a touch screen panel disposed to the first face of the display panel; and a digitizer panel disposed to the second face of the display panel through a pressing process, the digitizer panel comprising:
a digitizer circuit board;
at least one or more signal patterns constructed on a first face of the digitizer circuit board; and
at least one non-signal patterns constructed on the first face of the digitizer circuit board, and each disposed between each of the signal patterns.

11 . An electronic device comprising:
a housing comprising a first face facing a first direction, a second face facing a second direction opposite to the first direction, and a side face surrounding a space between the first face and the second face; a substantially transparent plate which constitutes at least part of the first face; a display layer disposed between the plate and the second face; a detection layer disposed between the display layer and the second face to detect whether an external object is in contact with or adjacent to the transparent plate by using an electromagnetic and/or magnetic change; and a processor electrically coupled to the display layer and the detection layer, wherein the detection layer comprises:
a first plurality of conductive strips that has a first thickness in the first direction, and extend parallel to one another and separated from one another in a third direction perpendicular to the first direction; and
at least one first pattern disposed between two adjacent conductive strips among the first plurality of conductive strips, and disposed to be substantially co-planar with the two conductive strips while having the first thickness in the first direction, wherein the first plurality of conductive strips are electrically coupled to the processor, and
