DATA TRANSMISSION SYSTEM FOR DISPLAY DEVICE, DATA TRANSMISSION METHOD FOR DISPLAY DEVICE AND DISPLAY DEVICE
First Claim
1. A data transmission system for a display device, the data transmission system comprising:
- an encoder having at least one translation table, and encoding m (m is a natural number) bits of a data into n (n is a natural number and n>
m) bits of a data on the basis of the translation table;
a clock recovery circuit of recovering a clock from the data encoded by the encoder;
a decoder of decoding the n bits of the encoded data to the m bits of the data in accordance with the clock recovered by the clock recovery circuit; and
an output driver of outputting a gray scale voltage in accordance with the data decoded by the decoder,wherein in the translation table, the larger the amplitude of the gray scale voltage of a bit pattern in pieces of bit patterns of the m bits of the data, the larger the data change index of the bit pattern which is assigned to the bit pattern in the 2m pieces of bit patterns in 2n pieces of bit patterns of the n bits of the data.

Abstract
A data transmission system for a display device, which is an mBnB encoding system encoding a signal of m (m is a natural number) bits into a signal of n (n is a natural number and n>m) bits on the basis of a certain translation table to be transmitted thereafter, the system including: an output driver of outputting a gray scale voltage in accordance with the data decoded at a receiver side, in which in the translation table, a bit pattern with a larger data change index from among 2n pieces of bit patterns of the n bits of the data is assigned to a bit pattern with a larger amplitude of the gray scale voltage from among 2m pieces of bit patterns of the m bits of the data.
