  • Routing for an integrated display and input sensing device
    Patent number: 10216302
    Abstract: Display devices with improved routing between connectors and source drivers disposed on a substrate such as glass. Various features improve different characteristics of the routings between the connectors and source drivers. For example, a t-shaped connector is provided to ensure voltage provided to the source drivers is approximately equal. Routings may be tapered (i.e., altered in width) to reduce the amount of area consumption in locations where doing so is desirable but to decrease resistance in areas having more space. Routings may also include stacked power supply and ground traces to provide benefits such as improved decoupling capacitance. Other features are provided.
