In recent years, home use televisions become thinner, lighter and more inexpensive, and therefore the demand for home use television's replacement has been increasing. And because they can be hung from the ceilings or on the wall, we can set them for fitting with our lifestyle. On the other hand, because many and various people use televisions in the home, they must be designed with the safety for users. Even if they are damaged by accident, the users must not suffer any harm. Furthermore, the realization of a lower cost thin television is necessary, and some new problems have been obvious. In this report, we introduce our new technology which solves the problems in making the thin, light and safety television sets in low cost. And we show some results of simulations and experiments.
