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: A data signal delay circuit and delay method and a display device are disclosed. The data signal delay circuit includes a feedback signal generation sub-circuit, a compensation signal generation sub-circuit, and a control sub-circuit. The feedback signal generation sub-circuit is configured to generate a feedback signal based on a first level signal from the first level signal terminal and a second level signal from the second level signal terminal under the control of a gate drive signal from a scan signal line currently being scanned. The compensation signal generation sub-circuit is configured to generate a compensation signal based on the feedback signal and a data enable signal from the data enable signal line. The control sub-circuit is configured to delay a data enable signal of the data enable signal line in a next cycle based on the compensation signal.

Abstract: Disclosed is a shift register unit, a gate driving circuit and a driving method, as well as a display apparatus. The shift register unit has a working cycle including an input phase, an output phase, a reset phase and a maintaining phase. In the reset phase, a clock signal is transmitted to an output terminal to pull a voltage of the output terminal down to a reference voltage, and the pulled-down voltage of the output terminal is subsequently changed from the reference voltage to a gate-off voltage. In the maintaining phase, the voltage of the output terminal is maintained at the gate-off voltage. The reference voltage is smaller than the gate-off voltage.
