We propose a universal image processor for a-Si TFT LCD of UXGA class that can display the full screen on the LCD panel with low resolution of video sources such as NTSC, VGA, SVGA, XGA, and SXGA by using the proposed interpolation filter. In addition, we propose a real-time contrast controller for image improvement of multi-gray scale image. The operation of the proposed methods has been verified using Synopsys VHDL and computer simulation. Results show that the proposed methods might be suitable for a UXGA LCD controller for real-time image improvement.

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.

This study uses the concept of dominant design to identify the determinants for the emergence of a next-generation dominant electronic display. It employs multiple research methods with the participation of display experts, which combine case studies, an unstructured interview, and the Delphi method. The results show that based on technological innovation and market dominance, a next-generation dominant display is more likely to emerge as a result of technological competition between liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). The findings emphasize that the importance of rapid technological innovation, including component and process innovations, and a competitive edge in manufacturing costs are important. The study sheds light on our understanding of dominance in an industry and market, and also provides strategic guidance for practitioners to establish a competitive strategy.

A portable terminal assistant market grows rapidly every year and it requires many change in research on display devices. Among many newly developing methods, OLED(Organic Light Emitting Diode) is considered an advanced flat display device because its excellent characteristics, including high speed response, full color performance, low power consumption and flux of panel. However changes in the market of display shows that the market will require 3-dimensional images, but it is hard for existing 2-dimensional displays to make 3-dimensional images. Therefore we will try to find various methods such as holograms. In this paper, we will show existing flat displays can make 3-dimensional images by applying Lenticular Screen printing techniques on the organic semiconductor display device.

Reflective paper-like display (PLD) using two types of particles having different electric polarity has been developed. A positive-charged particle has $TiO_2$, polymer and charge control agent (CCA), while a negative-charged particle consists of carbon black, polymer and CCA. We achieved fast response time (${\sim}0.2$ msec) and passive matrix driving addressing. These methods can easily be adapted to complete a large area display and flexible display.

After 1990's, many multi-level marketing companies lave been introduced in Korea. These MLM companies operate their stores as same way as general retailing stores. The major characteristics of these MLM companys' store is that their main customers are distributors who sell the purchased merchandise to another customers. Many studies about merchandise display in general retailing stores were reported. But, there was less research about merchandise display in these special type stores such as MLM companys' stores. This paper investigates the effects of merchandise display on distributor's merchandise selection in channel flow of multi-level marketing company. For this purpose, we formulated four hypotheses about display variance in quantity, height, location, and related merchandise to analyze the effect of merchandise display methods in MLM companys' stores. The experiment had been proceeded in three stores in a MLM company for 6 weeks and the sales data were collected by POS. The methods to analyze the data were used ANOVA and T-test. Findings of this study are as follows; First, there was no effect to store sale by the interaction effect between merchandise display method and scale of store. Second, scale of store affected considerably the volume of sales of each store according to main effect analysis. Third, display variance in quantity, height, and location did not affect store sale. In the related merchandise display, however, sale in all store was increased. Fourth, in additional analysis considering merchandise display only, display variance in both height and location affected their sale in large scale store. Based on the above results, we may predict merchandise display can affect sale in MLM companys' store as well as general retailing stores. Therefore if MLM company has large scale store, it should consider merchandise display methods in its stores.

Reflection measurements are critical to the evaluation of display performance under ambient illumination conditions. Various hemispherical reflection methods are evaluated for their suitability and robustness across display technologies. The standard integrating sphere method is compared to a sampling sphere apparatus.

Today, display is rapid changing with the rapid expansion of industrial society, the rapid changing of distribution structure, various world fairs and living environmental improvement. The extreme effect, visibility and imphasis are necessary for the efficient exhibition to show the invention Idea and products. Exhibition space's functions is to possess accumulative results and can communicate with visitors. The display in exhibition spare connect space, human and objects. This study is to systematize the display composition methods by the characteristics of arrangement and installation in display.

In this paper, we present a simple framework to measure BRDF(Bidirectional Reflectance Distribution Function) values of objects and to render them using the values more realistically. There are lots of BRDF measurement methods, but the methods have been separated from the effective rendering of the values. Therefore, we suggest the framework which includes the BRDF measurement methods of objects and the effective rendering methods of the measured BRDF data. Before measuring the BRDFs, we do light sources analysis, camera calibration and display device characterization. After measuring them, we apply them to the characterized display device for rendering effectively and realistically.
