In a gift to those who want to be surrounded by work 24 hours a day, Hitachi said Thursday it had developed a thin electronic paper that can be posted on walls bringing in messages by remote control.
Everything from family pictures to work schedules to recipes could be zoomed in through the paper, which measures 16.2 by 18.1 centimeters (6.48 by 7.24 inches), the Japanese hi-tech firm said.
And, in a future dreaded by techno-skeptics, the paper could theoretically be used to beam advertisements into homes.
The device is fitted with a solar-power panel and can be functional for several months without charging.
Hitachi plans to commercialize the product in 2006. No price has been set yet.
The three-millimeter thick electronic paper weighs 100 grams (3.5 ounces) with a lithium ion battery and liquid crystal display screen capable of displaying 64 colors.
Rival companies have developed electronic paper that appears in only two colors.
