Abstract: A panel display apparatus is provided which includes a timing controller, a plurality of source drivers, a first data path, and a second data path. The first data path and the second data path are both coupled between the timing controller and the source drivers. The timing controller transmits multiple display data to the source drivers via the first data path. When the source drivers detect an event (e.g. error event), the source drivers transmit at least one event data (e.g. notification data) to the timing controller via the second data path to notify the timing controller that event correction (e.g. error correction) is needed.
