摘要： 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 X 16 +X 5 +X 4 +X 3 +1, X 24 +X 4 +X 3 +X+1 or X 32 +X 7 +X 5 +X 3 +X 2 +X+1. The present disclosure reduces distortion of an image displayed on a display panel.

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 to obtain a decoded code stream. Whether the decoded code stream is the same as the initial code stream is detected, and 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, so that when it does not match with pre-set reference information of the timing controller, the configuration information is adjusted according to 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. The present disclosure solves a problem of low signal transmission efficiency, and therefore improves the signal transmission efficiency.

摘要： The present disclosure provides a compensation method and compensation device for a display screen, and a display device. The compensation method includes: adjusting a charging time for a plurality of areas of the display screen so that the charging time for each area to be charged is positively related to a distance from the each area to a data voltage input terminal of the display screen; comparing a first grayscale value before compensation of a sub-pixel in an i-th row and j-th column with a second grayscale value input to a sub-pixel in an (i-1)-th row and j-th column, where i and j are both positive integers, and i>1; searching a grayscale compensation parameter corresponding to the first grayscale value and the second grayscale value from a grayscale compensation parameter table in a case where the first grayscale value is not equal to the second grayscale value; compensating the first grayscale value by the grayscale compensation parameter to obtain a third grayscale value; and inputting the third grayscale value to the sub-pixel in the i-th row and j-th column for display. In the present disclosure, it is possible to allow that the display screen when displaying an image may reach a desired target grayscale value, thereby improving the display effect.
