Abstract
Embodiments of the present disclosure are related to a touch display device, as implementing a portion of a touch link line by using a metal disposed on a layer different from a layer where a data link line is disposed and disposing a color filter layer between the touch link line and the data link line, a plurality of link lines can be disposed effectively and a parasitic capacitance between the touch link line and the data link line can be reduced. Furthermore, as blocking a light of specific wavelength band by the color filter layer, a light-leakage due to an abnormal driving of a display according to a driving of the touch link line on an area where the touch link line is disposed can be prevented or at least reduced.
Claims20
A touch display device, comprising:
- a plurality of touch electrodes and a plurality of touch lines disposed on an active area of a display panel;
- a plurality of touch pads and a plurality of data pads disposed on a non-active area of the display panel, the non-active area located outside of the active area;
- a plurality of touch link lines disposed on the non-active area;
- and
- a plurality of data link lines disposed on the non-active area,
- wherein each the plurality of touch link lines comprises a first touch link line electrically connected to one of the plurality of touch pads, and a second touch link line disposed on a layer different from a layer where the first touch link line is disposed and electrically connecting the first touch link line and one of the plurality of touch lines,
- wherein each of the plurality of data link lines comprises a first data link line and a second data link line, the second data link line disposed on a layer different from a layer where the first data link line is disposed and electrically connected to the first data link line, and
- wherein a distance between the first touch link line and the second touch link line is greater than a distance between the first data link line and the second data link line.
A touch display device, comprising:
- a substrate;
- a plurality of touch electrodes and a plurality of touch lines disposed on a first area of the substrate;
- a plurality of touch pads and a plurality of data pads disposed on a second area of the substrate;
- a plurality of touch link lines disposed on the second area of the substrate;
- and
- a plurality of data link lines disposed on the second area of the substrate,
- wherein each the plurality of touch link lines comprises a first touch link line electrically connected to one of the plurality of touch pads, and a second touch link line disposed on a layer different from a layer where the first touch link line is disposed and electrically connecting the first touch link line and one of the plurality of touch lines,
- wherein each of the plurality of data link lines comprises a first data link line and a second data link line, the second data link line disposed on a layer different from a layer where the first data link line is disposed and electrically connected to the first data link line, and
- wherein a minimum distance between the second touch link line and the substrate is greater than a minimum distance between the second data link line and the substrate.
