The data transmission system for a display device, a data transmission method and a display device

The present invention relates to a data transmission system for a display device, a data transmission method and a display device. A data transmission system for a display device, the data transmission system is based on the specific conversion table hereinafter to be transmitted to the m (m is a natural number) signal encoding bits is n (n is a natural number and n> m) bits mBnB coding system signals, the system comprising: an output driver, the output driver outputs a gray voltage based on the data side decoder of the receiver, wherein, in the conversion table, the 2n bit patterns of n bits of data bit pattern change data having a large data index assigned to the m bits of 2m bits having a bit pattern of the gradation voltage amplitude larger pattern.
