  • Touch display panel
    Patent number: 10963114
    Abstract: The present invention teaches a touch display panel having a notch. A first resistance of a touch electrode is defined as the sum of a contact resistance between the touch electrode and the touch electrode's corresponding wire, and a resistance of the corresponding wire. For touch electrodes of an identical area, the touch electrodes have an identical first resistances. For touch electrodes of different areas, the touch electrodes of smaller areas have greater first resistances than those of the touch electrodes of greater areas. A consistent RC loading is obtained for touch electrodes of different areas, thereby effectively eliminating the touch and display differences resulted from the different areas of touch electrodes as the touch display panel has a notch design.
