摘要： 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.

摘要： This disclosure relates to a liquid crystal display and a display device. A plurality of photosensitive detectors is arranged in the frame region of the liquid crystal display panel. Light intensity distribution in the display region is estimated by a light intensity estimation module based on the light intensity detected by each photosensitive detector. Light intensity in a position corresponding to each light emitting pixel of the backlight source is determined based on the light intensity distribution in the display region estimated by the light intensity estimation module. Depending on the determined light intensity in a position corresponding to each light emitting pixel of the backlight source, luminance of the light emitting pixel in this corresponding position is controlled by a backlight driving circuit.

摘要： 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.
