Hitachi and Bridgestone Corporation will cultivate the market for electronic paper display solutions and will strive towards the commercial application of the displays.
Electronic paper display is ultra-thin and lightweight and combines the conveniences of both paper and digital media by realizing long-life operation via battery, and adopting a display module that has image retention ability and the drive, wireless communications circuit and memory embedded in. The image display doesn’t require electricity to run and the contents can be transmitted wirelessly. In this way, it can easily be set up in places where it is difficult to install power supplies and communication equipment. These features make it useful in communicating advertisements and other information, including that needed in times of emergency due to the disaster.
Hitachi recognized the potential of electronic paper displays early on and has been investigating into their commercialization. In December 2005, it conducted a field trial in conjunction with East Japan Marketing & Communications, Inc., the subsidiary company of East Japan Railway Company, in the Tokyo Station underground. Bridgestone, on the other hand, has already been successful in developing one that uses the company’s original Electronic Liquid Powder and has been researching into a diverse array of display modules. Bridgestone’s display modules were used in the field trial conducted by Hitachi.
Bridgestone will supply the display modules to Hitachi, which will use them in the production of electronic paper displays. Business will be focused primarily in transportation, electricity and urban development engineering. The aim is to provide total solutions by way of integrated display management, contents database management and remote transmission, for instance. Going forward, both companies will work in tandem to cultivate the electronic paper display market.
