Research paper : Development of flexible-printable device processing technology (T. Kamata et al.)−181 Synthesiology - English edition Vol.1 No.3 (2009) Next, new displays such as electronic paper (Phase II) do not require major technology as in television. Therefore, it is technology wanted by companies that wish to create new industry. In this case, new market must be pioneered, so discovery of function unseen in conventional technology will be the priority of development. However, there is limitation that the technology must be capable of fabricating relatively simple things. Although technology for simple display such as indicators and tags (Phases III, IV) may be simple, it can be technology from which totally new industrial product can be created, and it will be wanted by small & middle companies and ventures. Here, there may be more technological limitations such as unable to use expensive, special material or high cost manufacture technology, and therefore requires technological development dedicated for the purpose. Some examples of what can be read from the player map are shown.①Is the individual elemental technology to be developed in match with overall set-up concept? Are there any gaps in technology or player?②Does the technology to be developed have chance of becoming leading technology? ③Is the technology to be developed something that can be developed in multiple directions?④Can the technology to be developed gain competitive position?The technological position can be seen clearly on the player map, and it is extremely useful in judging whether a technology will become winning technology. “Winning technology” is determined based on whether it can lead new industry (leading technology), can respond to social demands such as energy conservation (social technology), or whether it can support industries with weakness in technological development (small-middle company supporting technology).4.3 Linear and non-linear models of technological developmentThere are two styles of technological development: linear model where clear, integrated goal is set and development is planned toward achieving that goal; and non-linear model where clear, integrated goal is difficult to set although target image is sort of there, and scenario to get to the goal is unclear, and appearance of jump-up technology is awaited (Figure 5). The latter non-linear model of technological development is often employed when specifications are diverse as in information terminal device technology.In the non-linear model of technological development, there is expectation for jump-up technology, and it is difficult to conduct development in an orderly manner. However, analyzing the technological fields that employ this model, there are many exceptions. The “information terminal device technology,” the topic of discussion in this paper, is one example. There is gap in technology because there is no technological player, and it looks as though people are waiting for jump-up technology to fill in the gap. In this case, clear planning can be done by organizing the existing technologies.4.4 Presenting effectiveness and innovativeness of technology as productIt is effective to present the developed technology, even if it is single technology, as prototype by combining it with related technologies. The point is to show that technological development can be done by using set of technologies, and to take lead in the technological concept. However, important point is to deliver clear message as well as fabricating a prototype and showing its function. For example, in the above development by the Authors, we added unique message. For “multiple-source photooxidation method,” our goal was to use it in printed TFT for display. In the initial stage of prototype fabrication, we were first in the world to succeed in showing moving image in color on organic TFT driven LC display (Figure 6)[3]-[5]. As this was time when many have high expectation for printed TFT technology, our demonstration (27)−Table 2.
