The MDDI interface standard is intended for portable imaging equipment regulated by group of VESA (Video Electronics Standards Association) under the image signal equipment. It is based on the LVDS transmission technology, supporting transfer rate is up to 3. 2Gbps. Using MDDI interface can reduce the number of connecting the signal lines to six, generally two data lines, one is for Stb, another one is for DATA. If multiple data, one is for Stb, the data lines were DATA0, DATA1,and thus reducing the noise interference problem.
