Uniform brightness is very crucial for LCD panels, which should be made in during manufacturing. Usually some compensating algorithms are applied to recover the brightness deviation that occurs in actual panels. Although such remedying tools are used, it is very hard to prevent horizontal or vertical crosstalks that represent the brightness level difference in horizontal or vertical direction. This research applied transformability Taguchi dynamic characteristics and “nominal is best” static characteristic simultaneously to design the compensating circuit optimally that may reduce the crosstalks and make uniform brightness level.

Most of process data control have been designed under the assumption that there are independence between observed data. However, it has been difficult to apply the traditional method to real-time data because they are autocorrelated, and they are not norm
