Alternatively, when the set temperature is displayed, only the segment corresponding to the temperature is turned on or blinked, and the temperature in the refrigerator can be displayed as a bar.
• FIG. 8 shows a circuit for driving the above-mentioned Yeouin display tube.
• the terminals R 16 to: R 20 and the terminal Og O are output to the multi-color display tube with their output voltages increased by drivers 39 and 40. As shown in FIG. This is because the luminous efficiency of the fluorescent paint differs depending on the paint, so that the intensity of the paint with poor luminous efficiency is increased.
