As a bright star of manufacture process development, the inkjet fabrication has penetrated into the field of display and semiconductor, for example, the fabrication of color filter, the forming of metal circuit, the dispensing of liquid crystal, and further continuous manufacture of flexible display etc. Would it be ideal and expectable? The obstacle lies across is the throughput rate, or the data transfer speed compromises of printing speed. Prior researches suggested to equipping multiple ink-jet heads to speed up printing and patterning, however, it was unfavorable for some applications need high class environment, because of its huge platform occupied and high cost expense. This article designed an electrical system with twin memory arbiter to swing the image data while printing and substrate delivery. It was realized by piping the image data in a multiplexer, and then transferring the data follow with printing process and substrate delivery synchronously. In thus design, the printing head is always kept on its maximum firing speed and the jetting quality can be maintainable. Estimation of the performance improving, the save of waiting time would be 40% or above, and is also accessible for mass production needs.
