摘要： This application relates to an encoding method and apparatus, and a display apparatus. The encoding method includes encoding 8-bit data corresponding to a to-be-encoded byte of to-be-transmitted data into alternative 10-bit data, the to-be-transmitted data including at least one to-be-encoded byte, detecting whether the first-digit data of the alternative 10-bit data is the same as the previous-digit data adjacent to the first-digit data, when the to-be-encoded byte is not the first byte of the to-be-transmitted data, inverting the alternative 10-bit data to obtain target 10-bit data, when the numerical value of the first-digit data is the same as that of the previous-digit data, and determining the alternative 10-bit data as the target 10-bit data, when the numerical value of the first-digit data is different from that of the previous-digit data. The 8-bit data, the alternative 10-bit data and the target 10-bit data are binary data.
