The concepts of flexible displays and plastic electronics have become some of the most talked about new product opportunities for direct view flat panel displays in recent years. The potential advantages are frequently cited, but the achievement of commercially viable products will require many significant technological innovations in new materials and manufacturing technology. This paper will provide a very broad overview of the rationale for developing flexible displays, the market drivers, the applicable display technologies, the major hurdles that must be overcome and the required evolution of new manufacturing technologies that are essential for successful commercialization. This is intended to provide the outline and context for the series of presentations on specific aspects in each of these topics that will be delivered and discussed at the Plastic Electronics Special Session of the 2005 IMID conference.

This paper describes the realization of the full-color to the degree of nearest white light by compounding high brightness Red, Green and Blue LEDs with appropriate proportional index. Once these three colors; red, green and blue are mixed, they are genearlly additive mixing and produce white light color contrasted to negative mixing. The luminous efficiency is defined as the product of the efficiency(lm/w), which indicates the degree of perceptual response by the human eye to unit energy(W) of light emitted by an active display devises and as the conversion efficiency of the device from electric power consumed to optical energy produced. We will deduce the each number of LEDs theoretically and design several shapes of LED displays for the full-color. Finally theoretical predictions will be compared with the measured data with different type of display designs.

In general wireless power transfer systems (WPTSs), power transfer is controlled by the wireless communication between a transmitter (Tx) and a receiver (Rx). However, WPTS is difficult to apply in electronic products that do not have batteries, such as TVs. A WPTS with resonators based on a transformer of LLC series resonant converter is proposed in this study to eliminate wireless communication units between a Tx and an Rx. The proposed system operates at the boundary of the resonance frequency, and the required power can be stably supplied to authorized devices even though some misalignment occurs. Moreover, standby power standards for the electronic product can be satisfied.

At present, the Korean display industry lacks significantly in qualitative achievements when compared to quantitative achievements. Of course, there are various systems established according to the developments of display design organizing methods, production, and installing methods through some preceding studies related to display, but it is true that the wholistic management through display business management process which is prerequisite for this field is now considered yet. This has led to consistent and repetitive limitations, although many have undergone numerous trials and errors, along with related conflicts during implementing display business. Accordingly, organizing process and system for display business management field is the most field to be studied in order to not follow suit of the existing problems and look back on the failure factors of past display business. This study is focused on studying stage-to-stage research on organizing process and system for display business management, and aims to provide basic information for a more efficient management which can be realized during future business implementation for display culture facilities. The followings are the conclusions for this study. First, in order to successfully implement display business, the role of display business management is crucial, and the related need for display business management operations was proved. Second, the viability of 'Check-List for examining displaying product designs, production and installment' was verified, along with suggestions for additional factors to be considered in the examining check-list. Finally, third, the analyzing process of this study is focused on analyzing the facilities according to justifiable analysis factors. However, there are limitations such as corning up with subjective facts which can be known through naked eyes. Thus, the necessity for additional researches which can supplement the limitations of this study was found.

The purpose of this study is to investigate the details of the overall interior design of the department store supermarket retail space, interior design and development, seeks to help change. In this study, a range of research the department store supermarket located in the major department store. Since 2012, new construction or renewal has been done in a department store, was investigated by selecting a total of five locations of two places in the premium supermarket. Conclusions are as followings ; First, In-store merchandising strategies, store configuration strategy, product mix strategies, and the layout plan considering the advanced strategies. Secondly, the interior guidelines are, (1)VP should be planned as an expression of a company or brand management strategies to visualize a concept image of product planning stages of merchandising to entering the store to induce curiosity to customers. (2)PP is by planning purposes, the use of lighting, directing structure, color harmony, by utilizing such as props and small parts must be able to attract attention. (3)IP is the customer to organize display, depending on the type of the display items to facilitate fraud, and the fixture plan in association with it, the customer selects a product must induced to purchase.

Recently, specifications of flat display module is going to be higher definition, brightness and more wide viewing angle. On the other hand, physical thickness of those modules is forced to be slimmer and lighter. The flat display modules such as plasma or TFT-LCD employ thin crystallized panels that are normally weak to high level transient mechanical energy inputs. As a result, anti-shock performance is one of the most important design specifications of TFT-LCD modules. TFT-LCD module manufacturers and their customers like PC or TV makers perform a series of strict impact/drop test for the modules. However most of the large display module designs are generated based on engineer's own trial-error experiences. Those designs may result in disqualification from the drop/impact test during final product evaluation. A rigorous study on the impact failure of the displays is of course necessitated in order to avoid the problems. In this article, a systematic design evaluation is presented with combinations of FEM modeling and testing to support the optimal shock proof display design procedure.

Predictive modeling schemes have been developed to characterize the heat Transfer and thermo-mechanical behavior for the plasma display panel (PDP) in operation. The inverse approach was adopted to predict the accurate temperature distribution and deformation in PDP. The predictive models were validated with the measurements from real panel. The developed models could be utilized to predict and/or improve the product quality of PDP.
