Abstract

PURPOSE:To facilitate easy portability as well as to attain the driving with a low level of voltage, by using a liquid crystal display which can be miniaturized with small thickness. CONSTITUTION:The video signal is fed by a video jack 1, and this device is provided with a power supply switch 2, a contrast control knob 3, a brightness control knob 4, a liquid crystal panel 5, a video input terminal 6 and a battery box 7. For the power supply two UM-3 batteries are used. Then the screen is controlled by turning the knobs 3 and 4 while looking at the screen of the panel 5.
