  • Patent number: 11069275
    Abstract: Provided are a timing controller, and a driving method and a display device thereof. The timing controller may include a detection circuit and a control circuit. The detection circuit may detect a symbol error rate of a drive signal transmitted from a control circuit to a source drive circuit, and send the symbol error rate to the control circuit. The control circuit may automatically adjust a voltage swing of the drive signal according to the symbol error rate of the drive signal, and may enable a magnitude of the adjusted voltage swing to negatively correlate with a magnitude of the symbol error rate. Therefore, electromagnetic interference is effectively reduced, and flexibility in reducing electromagnetic interference is improved.

  • Patent number: 10789904
    Abstract: A method and a device for driving a display panel, and a display device are provided. The method includes: dividing the display panel into at least two display regions, where each display region corresponds to a timing controller, and the timing controller is configured to control the corresponding display region to display; dividing each display region into multiple detection blocks; detecting whether a defect block exists in each display region; and enabling, when the defect block exists in only one display region, by the timing controller corresponding to the only one display region, a pattern detection function, and enabling, when the defect block exists in each of more than one display region, by the timing controllers corresponding to the more than one display region simultaneously, the pattern detection function.
