Timing-controller-controlled power modes in touch-enabled source drivers

A display device, comprising:

• a plurality of common electrodes;
• at least one source driver coupled to the plurality of common electrodes and configured to drive the plurality of common electrodes for display updating;
• a timing controller coupled to the at least one source driver via a communication link, the timing controller configured to:
• receive, via the communication link, an uplink signal including operating information of the at least one source driver;
• determine an equalizer bias setting for the at least one source driver based on the received operating information of the at least one source driver;
• and
• transmit, via the communication link, a display data signal to the at least one source driver, the display data signal including timing control information and the determined equalizer bias setting for the at least one source driver;
• wherein the at least one source driver is configured to reduce its power consumption based on the determined equalizer bias setting.

A method for operating a source driver of a display device, the method comprising:

• receiving, from the source driver via a communication link, an uplink signal including operating information of the source driver;
• determining an equalizer bias setting for the source driver based on the received operating information;
• transmitting, to the source driver via the communication link, a display data signal including timing control information and the determined equalizer bias setting;
• and
• reducing power consumption of the source driver by causing a modification of sensing operations of the display device based on the determined equalizer bias setting.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor of a system including at least a source driver coupled to a display device, causes the system to reduce power consumption of the source driver by performing operating comprising:

• receiving, via a communication link, an uplink signal including operating information of the source driver;
• determining an equalizer bias setting for the source driver based on the received operating information;
• transmitting, to the source driver via the communication link, a display data signal including timing control information and the determined equalizer bias setting;
• and
• modifying sensing operations of the display device based on the determined equalizer bias setting.
