At last, the result of real test is that the height of curl reduces averagely to 54.6% and Cpk increases from 0.94 to 1.36. The NG ppm drops off apparently before improvement from 11053.02ppm to 1267.37ppm and it doesn't'' result any other side effect of quality under relative process inspection. The benefit of improvement is estimated to save the inner failure cost of production about NT 1127.8 thousand dollars. It proves that this research case can improve effectively the curl quality of polarizer in LSG process.
