摘要

The display has a lighting plate placed behind a LCD screen (1), and a power supply unit. The lighting plate has two light sources i.e. incandescent bulbs (2, 3) in which one light source radiates in a visible spectrum, and another light source radiates in a spectrum having a radiation pattern that excludes a sensibility pattern of light intensification tubes. The power supply unit has an inverter type switch (5) to light one of the light sources. The incandescent bulb (2) has surrounded with a filter (4) for suppressing the radiations whose wavelength is detected in the sensibility pattern.
