  • Patent number: 10937347
    Abstract: The present disclosure relates to a signal detection method and component, as well as a display device. The display device includes a timing controller and a source driver. The source driver receives a test code stream from the timing controller, which is obtained through encoding of an initial code stream by the timing controller, the initial code stream representing a test signal. The source driver decodes the test code stream. When the decoded code stream is different from the initial code stream, configuration information of the source driver is acquired. The configuration information is transmitted to the timing controller, and is adjusted according to reference information of the timing controller when it does not match with the reference information. The source driver receives adjusted configuration information transmitted by the timing controller, and then receives a subsequently transmitted signal according to the adjusted configuration information.
