Scrambling method, descrambling method and display device

The invention discloses a scrambling method, a descrambling method and a display device, and belongs to the technical field of data transmission. The scrambling method is applied to a sending end of the display device, and comprises the following steps: scrambling a plurality of display data sequences in image frame data by adopting at least two different scrambling codes to generate a plurality of display coding sequences in a frame display data packet. According to the embodiment of the invention, the autocorrelation of the scrambled coded data can be reduced, the coding randomness is improved, and the anti-EMI capability in the data transmission process is improved. 本发明公开了一种加扰方法、解扰方法和显示装置，属于数据传输技术领域。加扰方法应用于显示装置的发送端，所述加扰方法包括：采用至少两种不同的扰码，对图像帧数据中的多条显示数据序列进行加扰，生成帧显示数据包中的多条显示编码序列。本发明实施例可以降低加扰后的编码数据的自相关性，提高编码随机性，提高数据传输过程中的抗EMI能力。
