Abstract
A portable information terminal unit comprises a first and a second casing, a hinge means for coupling the first and second casing so that the first and second casing are rotatable relative to each other, an opening piercing though the first casing, a first see-thorough liquid crystal display part fitted in the opening, a means for detecting opening of the first and second casing, relative to each other, and a control means for reversing a display on the first see-through liquid crystal display part in response to a detection by the detecting means, wherein monochromatic information is displayed on the first see-through liquid crystal display part so as to reduce power consumption.
