Scalable intra-panel interface

摘要

A system and a method are disclosed for an intra-panel communication interface which, among other advantages, enhances system reliability and reduces bus width. A timing controller initializes communication with a plurality of source drivers by transmitting link data through a plurality of data channels and monitors source driver status through an auxiliary status channel. The plurality of source drivers share the auxiliary status channel to indicate their status. The timing controller transmits display data to a source driver through a data channel. The display data includes a request for status data from the source driver. The source driver transmits the requested status data to the timing controller via the auxiliary status channel.

主权项

1. A method for intra-panel communication, the method comprising:
receiving display data at a source driver in a packet based transmission, the display data including a request for status data; recovering clock information from the received display data; setting a status output signal of the source driver to a high state responsive to recovering the clock information; and transmitting, when the status output signal of the source drive is at a high state, requested status data from the source driver via an auxiliary status channel while continuing to receive display data via a data channel, the auxiliary status channel shared by a plurality of source drivers.
