摘要

A differential data array group, which have at least a plurality of pairs of a differential data to transmit a serial signal, includes difference absolute value data having a plurality of bits to represent an absolute value obtained by converting gray scale level data of red, green and blue to binary number data, and sign data having at least one bit to represent a sign of the gray scale level data. With respect to one pair of the differential data, gray scale level data corresponding to one pixel are arranged in an ascending order or a descending order. With respect to another pair of the differential data, the sign data corresponding to one pixel are arranged into a former half or a latter half of a time period corresponding to one pixel. Data of a highest order bit of the difference absolute value data corresponding to one pixel are arranged into the latter half or the former half of the time period corresponding to one pixel.
