A self-biased differential transmitter is provided. The transmitter may include a differential output driver powered by a supply voltage provided by a differential signal receiver. The output driver may include a bias voltage generator to generate bias voltages to enable one or more transistors in the output driver to operate with differential signals that are beyond the safe operating voltage range of transistors included within the differential transmitter.

Self-biased differential transmitter

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.

Routing for an integrated display and input sensing device

This disclosure generally provides a processing system that includes a first controller coupled with a second controller via a first communication link. The first controller is configured to transmit display data and configuration data to the second controller via the first communication link. The second controller is configured to drive, using the display data, one or more coupled display electrodes for performing display updating. The second controller is further configured to operate one or more coupled sensor electrodes using the configuration data to acquire capacitive sensing data, and to transmit the capacitive sensing data to the first controller via the first communication link.
