On the other hand, the latter, as exemplified by display, emphasizes “diversification,” “mass diffusion,” and “usability,” and there are demands to accommodate various uses and places where the technology is used. For further diffusion and expansion of IT technology, diffusion of information terminal is essential, and creation of more convenient terminal is awaited. To create new information device, it is important to understand the market demand. Particularly, as the general public is becoming accustomed in using the network, demands for usability are increasing. For example, we well as demands for hardware such as being light, thin, or doesn’t break when dropped, there are demands for usability such as not being affected by place or environment in which the device is used (everywhere device), or user can customize the device to 1 Background: flexible information terminal device in demandAs IT technology has deeply penetrated the society today, development of technology that improves usability will diffuse IT technology further and is expected bring forth economic impact. The new technology may also contribute to sustainable society by conserving resource and energy for transportation and communication. The development of technologies for software and hardware for sustainable society is being conducted actively, and the international competition in this field is becoming fierce.The hardware for IT technology can be roughly divided into “central-mainline technology” where information are collected and processed and “terminal-access technology” where information are received and distributed (Figure 1).

We have succeeded in the development of several low-temperature printing technologies for flexible active devices such as flexible displays and circuits. In this research, we have paid attention especially to the social requirements for the technology, and positions of respective technologies in the total set-up concept. We believe that it would contribute to the expansion of information technology in the world.Development of flexible-printable device processing technologyKeywords : Display, information terminal device, flexible device, process innovation, organic semiconductor, printing[Translation from Synthesiology, Vol.1, No.3, p.190-200 (2008)](23)−Fig. 1 Development of flexible printable electronics technology.産総研4.11つくば東22.Branching and diffusion of network terminalManufacture and provide extremely thin, lightweight, flexible device using highly productive process ◆ Everywhere device, everyone deviceEffectTechnology to apply semiconductor device at low temperature on a plastic film◆ Flexible printable device technologyDevelopmental technology◆ Provide function wanted by end user Increase usabilitySheet cameraAmbient sensorElectronic paper (flexible sheet display)IC price tag,IC shipping tagProduction control tagFlexible printable device technologyDisplayPCCardMobile phoneTerminal-access systemFrequency, diffusionInformation triangleCentral-mainline systemSuper computerOptical communicationSystem LSI(Uninterrupted, low capacity, diversification)BranchingPerformance(Super high-speed, high capacity, standardization)High integration◆ Expand horizon of IT technology Expand economy◆ Reduce weight and power consumption of terminal AimPromote energy conservation by mass diffusion terminal
