Abstract: The present disclosure provides a compensation method, compensation device, and a display device. The compensation method includes: adjusting charging time for multiple areas of the display screen so that the charging time for each area is positively related to a distance from the area to a data voltage input terminal; 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; searching a corresponding grayscale compensation parameter from a grayscale compensation parameter table according to the first grayscale value and 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.

Abstract: A signal transmission method and related timing controller, source driver and display device are disclosed. The method includes scrambling a signal to be transmitted by a transmitting unit to obtain a scrambled signal. Each frame of the scrambled signal includes at least one first identification signal sequentially arranged in time domain, and a number of the first identification signals in the scrambled signal is equal to a number of the first identification signals in the scrambled signals of other transmitting units in the plurality of transmitting units. The method includes transmitting the scrambled signal to a corresponding receiving unit, where the first identification signal is configured to indicate linear feedback shift registers of the transmitting unit and the corresponding receiving unit to perform a reset operation, and after each collective reset operation is completed, the corresponding receiving unit outputs a display signal to the display panel.

Abstract: This application relates to an encoding method and device, a decoding method and device, and a signal transmission system. The encoding method includes: encoding 8-bit data corresponding to a to-be-encoded byte of to-be-transmitted data into 9-bit data, the to-be-transmitted data comprising at least one to-be-encoded byte; detecting the first digit of data of the 9-bit data and a previous digit of data adjacent to the first digit of data, when the to-be-encoded byte is not the first byte of the to-be-transmitted data; inverting the 9-bit data and then adding a tenth digit of data for indicating that the inverted 9-bit data has undergone an inversion operation behind the inverted 9-bit data to obtain 10-bit data, when the numerical value of the first digit of data is the same as that of the previous digit of data; and adding a tenth digit of data for indicating that the 9-bit data has not undergone an inversion operation behind the 9-bit data to obtain 10-bit data, when the numerical value of the first digit of data is different from that of the previous digit of data.
