Cu oxide has been deoxidized in an extremely low oxygen partial pressure atmosphere. The oxygen was evacuated to 10-28 atm using a newly developed oxygen reduction system (ORS). It was experimentally demonstrated that the surface oxide of Cu film was completely removed by exposure to such an environment at 200 °C. The proposed deoxidization reaction can be used as a new Cu surface cleaning technique.

The algorithm to reduce the memory capacity in FFD (Feedforward Driving) is discussed. FFD improves the motion video on LCD. The application of image compression technology achieves approximately one tenthorder reduction of memory capacity.

The authors have developed a LCD module that adopts a color conversion circuit which can contribute to the improvement of imperfect color reproduction in the LCD panel. The new module adopts a color conversion circuit that uses a new matrix calculation which we have developed. This color conversion circuit allows support of motion picture display and real time processing. In addition, it enables realization of desired color conversion characteristics and it also facilitates realization of use of two or more types of color conversion characteristics by selection.
