  • Publication number: 20140078133
    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.

  • Publication number: 20140049524
    Abstract: A method for displaying error rates of data channels of a display is provided. A timing controller of the display repeatedly transmits a test signal with a specific format to a first and a second source drivers of the display via a first and a second data channels of the display. During testing, a first number and a second number of times of the first source driver and the second source driver determining that the received test signal does not have the specific format are counted respectively. The first and the second source drivers control displaying of a first area and a second area of a panel of the display respectively according to the counted first and second numbers of times. Accordingly, the error rates of the data channels are presented on the panel of the display in a way that the error rates could be recognized more easily.
