Display device with touch panel
View Patent ↗A display device with a touch panel includes the touch panel having a first substrate having a detection area to detect a coordinate and an outside area in which at least one external terminal is formed, a plurality of first lines to detect the coordinate in the detection area, a plurality of second lines to detect the coordinate in the detection area, wherein each of the plurality of first lines traverse each of the plurality of second lines. An organic emitting display panel is arranged under the touch panel, and a circular polarizing plate arranged at a side of the touch panel opposite to the organic emitting display panel. The organic emitting display panel, the touch panel, and the circular polarizing plate are arranged in this order.
1. A display device comprising:
an organic emitting display panel:
a predetermined layer arranged above the organic emitting display panel:
a touch panel, arranged above the predetermined layer:
first lines to detect a coordinate in a detection area; and
a circular polarizing plate, arranged above the touch panel, adhering to the touch panel, wherein
the lines include metal lines which overlap the predetermined layer,
the predetermined layer is softer than the circular polarizing plate,
a width of the metal lines is less than 50% of a wiring pitch of the metal lines,
the lines include ITO lines
the ITO lines overlap a region where the metal lines overlap the predetermined layer and
the circular polarizing plate;
the lines include outside lines arranged outside the detection area and
a wiring pitch of the outside lines is narrower than a wiring pitch of the lines in the detection area.
2. A display device according to claim 1 , further comprising a display panel, wherein at least a portion of the display panel does not overlap the circular polarizing plate in a plan view.
3. A display device according to claim 2 , wherein the lines include first lines and second lines,
the touch panel includes a plurality of wiring groups,
each of the plurality of wiring groups has some of the first lines, and
some of the first lines in each of the plurality of wiring groups are banded in each other.
4. A display device according to claim 3 , wherein each of the second lines and the first lines is made of metal, and each of the first lines is black in color.
5. A display device according to claim 4 , wherein a transparent conductive film overlays the first lines, and wherein the transparent conductive film is electrically connected to the first lines.
6. A display device according to claim 4 , wherein a transparent conductive film underlays the first lines, and wherein the transparent conductive film is electrically connected to the first lines.
7. A display device according to claim 3 , wherein a transparent conductive film overlays the second lines, and wherein the transparent conductive film is electrically connected to the second lines.
8. A display device according to claim 3 , wherein a transparent conductive film underlays the second lines, and wherein the transparent conductive film is electrically connected to the second lines.
9. A display device according to claim 2 , wherein the touch panel is a resistance-film-type touch panel.
10. A display device according to claim 2 , further comprising:
a first adhesive layer between the touch panel and the circular polarizing plate, wherein the touch panel and the organic emitting display panel are fixed in each other by the seal material,
wherein the touch panel and the circular polarizing plate are fixed in each other by the first adhesive layer.
11. A display device comprising:
an organic emitting display panel:
a predetermined layer arranged above the organic emitting display panel:
a touch panel, arranged above the predetermined layer:
lines to detect a coordinate in a detection area; and
a circular polarizing plate, arranged above the touch panel, adhering to the touch panel,
wherein the lines overlap the predetermined layer,
the predetermined layer is softer than the circular polarizing plate,
the lines include metal lines,
a width of the metal lines is less than 50% of a wiring pitch of the metal lines,
the lines include ITO lines
the ITO lines overlap a region where the metal lines overlap the predetermined layer and
the circular polarizing plate;
the lines include outside lines arranged outside the detection area and
a wiring pitch of the outside lines is narrower than a wiring pitch of the lines in the detection area.
