Advancements in FPD Create Need for Standardization
By Dr. Jong-Seo Lee, Samsung
Since the advent of CRT displays the extraordinary advancements in FPD, including LCD and PDP, have distributed great economical and cultural benefits to both the display industry and to consumers.
However, there are still extensive standardization issues that are due in part to these rapid FPD advancements. Furthermore, the various benefits that the display industry and consumers enjoy have not reached their optimum states. In other words, the industry cannot pursue the highest profit levels due to the investments of cost and time required for development. This is attributable to the lack of standardization.
Currently, the international standardization activities related to the display industry are divided into state-led standardization efforts, such as ISO, IEC, and ITU, and industry-led standardization activities, such as SEMI, VESA, and TCO. Unfortunately, none of these standardization activities have developed a standard fully prepared for the future. This means that the standards are developed only after new display technologies were commercialized and distributed to consumers. One of the biggest problems this situation creates is that standards can become meaningless when they are established long after technologies have been commercialized−meaning efforts for standardization can come to nothing. If technology and market preparations could be made for future display-related technologies, then an optimal standardization process would emerge. This is quite difficult in reality. However, such efforts must be made. As previously stated, it is necessary to consider the fact that standards will not provide substantial support to the industry when the establishment of such standards takes too much time or is done after the fact.
Standardization has advantages
From this point of view, SEMI’s FPD standardization activities have a number of advantages. First, the industry that adequately prepares for business and technology can properly prepare standards for the future. Unlike the state-led standardization activities such as ISO, IEC, and ITU, the standardization activities of SEMI are led by industry, giving SEMI unlimited potential to quickly cope with issues arising in the industry. Secondly, it can considerably reduce the time required for the establishment of standards compared to other standardization organizations. Quickening the process does not always promise positive results. This is dependent on the integrity of the standard itself. However, the relatively simplified procedure clearly has some advantages. Therefore, the industry must take the responsibility to ensure the timely establishment of applicable standards desired by the industry and consumers when undertaking future FPD standardization activities using these advantages.
One of the largest issues in the current display industry is the technological development for future displays. While there are no schemes for the standardization of the process, technology, and evaluation of reflective type displays, Flexible display, 3D display, and OLED display−yet to be fully commercialized−SEMI’s FPD standardization activities should become an important part of all standardization activities in the future.
Currently, SEMI Korea FPD TC is making preparations to achieve this. (Figure 1)

It is not desirable to carry out a series of activities for the standardization of key future technologies dependent on a Korean effort alone. It is more desirable to emphasize the need for the organization of cross-functional teams by forming committees in each region in order to efficiently make advance preparations. SEMI HQ must carefully consider the further intensification of the system through which experts from many regions interested in establishing standards that cannot be established in any one specific region of the world can organically exchange knowledge and information. In the near future, there will be other great changes for the display industry to face, and being fully prepared for such changes seems to be the most rational standardization activity to undertake. This will become a significant contribution to the industry and consumers alike, bringing vast economic and cultural benefits. SEMI has a system optimized for such preparations, and I sincerely hope SEMI becomes the leader of display standardization activities in the future.
