A touch pad controller includes a voltage generator and a selector circuit. The system includes a processor coupled to a database and a display. Thus, noise is removed without modifying the design of the filter circuit depending on the system in which the memory module is incorporated. The light generating layer diffusely reflects and randomizes the polarization state of the reflected light and recirculates the reflected light back to the reflective polarizer. That is, the screen contents of the second sub display apparatus 8 are transformed to the main display apparatus 6, and the screen contents of the main display apparatus 6 are transformed to the second sub display apparatus 8. Additionally, a composition is disclosed that comprises: A) at least one nitroxyl compound, and B) at least one quinone alkide compound having an electron-withdrawing group at the 7-position.
