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.

Abstract: The present disclosure relates to a method and device for transmitting a signal in a display device. The display device comprises a timing controller and a source driver. The method is applied to any of a plurality of transmitting units of the timing controller. The plurality of transmitting units correspond to a plurality of receiving units of the source driver in a one-to-one relationship. The method comprises: obtaining a scrambled signal by scrambling, via a scrambler of the transmitting unit, a non-identification signal in a signal to be transmitted, the scrambled signal comprising an identification signal and a scrambled non-identification signal; and transmitting the scrambled signal to a corresponding receiving unit. A signal obtained by scrambling a signal X via the scrambler is X16+X5+X4+X3+1, X24+X4+X3+X+1 or X32+X7+X5+X3+X2+X+1. The present disclosure reduces distortion of an image displayed on a display panel.

Abstract: The present disclosure describes a data transmission method, a timing controller, a source driver, and a data transmission system. The method includes: when the timing controller transmits data to the source driver at a speed n times a preset speed, the timing controller suspends transmission of valid data with the source driver after completing transmission of a first data packet; and the transmission of valid data with the source driver is resumed at a transmitting time of a second data packet; the first data packet and the second data packet each includes valid data of a row of sub-pixels, or each includes valid data of a frame. The present disclosure completes the transmission of the first data packet in advance by increasing the transmission speed, then suspends the data transmission, and resumes the data transmission at the transmitting time of the second data packet, thereby reducing the power consumption.
