Abstract
A touch panel display subsystem for bi-directional intra-panel communication includes a forward link and a backward link between a timing controller and one or more source drivers. The forward link includes a timing controller transmitter in the timing controller to receive video signal, video control signal and touch control signal, and to transmit over the forward link in the format of frame based packet, and a source driver receiver in the source driver to receive video signal, video control signal and touch control signal over the forward link. The backward link includes a source driver transmitter in the source driver to receive the touch sensor data and transmit the touch sensor data over the backward link when the backward link is enabled, and a timing controller receiver in the timing controller to receive the touch sensor data over the backward link when the backward link is enabled.
