A voltage biasing circuit includes a metal-oxide-semiconductor transistor, a voltage control circuit controlling a voltage between a gate and a source of the MOS transistor to operate the MOS transistor in a sub-threshold range, and a capacitor connected to the MOS transistor. The bearing arrangement includes at least two fluid pressure bearings having a membrane formed as a support end. This rear projection screen construction can give rise to increased efficiency and higher contrast, as well as allow for more design freedom in constructing screens that have desired characteristics such as viewing angle, viewing asymmetry, and the like. PIN diodes are connected between the respective extension elements and the respective outer ends of the dipole antenna.
