We propose a hole-filling method to solve discontinuous depth representation and to reduce the visible seams and cracks that cause the limitation of the viewing angle of the three-dimensional (3D) image in the multilayer type 3D display system. The occlusion and the disocclusion regions between layers, such as the visible seams and cracks, are a major bottleneck of the multilayer type 3D display system to represent a volumetric 3D image by stacking multiple images. As a result, in the reconstructed 3D image, the visible seams and cracks appear as brighter overlapping and undesirable cut-off. In order to resolve the problems above, we applied the depth-fused effect to the sub-depth map generating algorithm and improve the viewing characteristics of the multilayer type 3D display. The experimental demonstrations are also provided to verify the proposed scheme.

High-density directional display provides natural three-dimensional images. A large number of directional images are displayed in different horizontal directions with directional rays. There are two different types of display configurations. One is the projection-type and the other is the thin-type. The 64-directional and 128-directional displays using the projection-type configuration and the 72-directional display using the thin-type configuration are presented. The human responses are also shown.

The toner type paper-like display (PLD) has been developed with two polymer particles having opposite polarity composed of polymer, colorant and external additives (nano-sized silica). Nano-sized silica with triboelectric charge was used for the charge control agent (CCA) and influenced on the electrostatic properties of the silica-coated polymer particles. The surface morphology and the cohesiveness of silica-coated polymer particles were changed with the silica coating time. From these results, it was verified that the PLD cell using silica-coated particles (200 seconds) shows a good white appearance and low driving voltage.

Polymide is widely used alignment material of recent commercial LCD panel structure. Generally, polyimide alignment material is classified soluble polyimide type and polyamic acid type with their main bond structure of solution state. specially, compared to polyamic acid alignment layer, soluble polyimide type alignment layer have excellent reliability during long term LCD driving cause of their high imidazation ratio(%), high voltage holding ratio(%) and low ion density. The other side, this type alignment materials has significant DC image stickicng side effect for using in-plane switching mode lcd structure cause of their slow DC discharging property. we applied inorganic salt to usual soluble polyimide type alignment layer and found out this technique had good DC image sticking property without any loss of reliability property in inplane switching LCD cell structure. This approach leads excellent DC image sticking property with maintaining high reliability property this approach confirmed improves an image sticking and a reliability simultaneously from the horizontality aligned LCD mode whose relatively bad image sticking property.

This study was to find the display considerations of RDA resource type - content type, media type, and carrier type. The Literature review, the case study, and the survey were used as the research method. 5 display strategies were suggested in this study. First, content and carrier types were better displayed than all 3 types of RDA resources. Second, two kinds of algorithm should be considered for RDA resource icon display. One was the combination of the terms of carrier types plus content types icon. The other was the combination of carrier types icon and content types icon in which the terms reflecting types must be included. Third, the subfield of 33x must be used for the paired display of content type and carrier type of multi-types resources. Fourth, in brief display, resource type icon was better positioned on the left and upper side and in detailed display, resource types were better located in description area. Fifth, 'format' was used as display indication phrase. This study would contribute to the design for the resource display by suggesting the practical display considerations of RDA resource type.

With the increase of visitors to rural tourism villages, the direct selling at sites is getting vitalized. Accordingly, their display stores is getting more important. Therefore, this study has selected 30 domestic rural tourism villages as study objects for the attitude survey of 200 farming suppliers and the site examination for the designs of those display stores in order to analyze their status and classify the types of necessity. Such operation status as sale item, sale method, method of supply and demand, major customer, sales scale, manager, opening hour, and operation cost were examined, to identity and for design factors the pattern, material quality and color were investigated. For the attitude of farming suppliers, the tactics of sales, the reason for being positive or negative, the functionality and the features of display stores were examined through brainstorming. IBM SPSS Statistics 20 Program was employed for Frequency, which indicated that village chiefs and store managers with the sales scale of 1 to 20 million won are dealing with female customers in their 40's and 50's and that those stores are open at the time of experience or year round without any operation expense. Permanent type and Fixed type were found to be the design factors of the display-case type with the material and the color of wood and orange respectively. The result of investigation analysis of farming suppliers' attitude showed the followings: the need of display stores is quite high, structure type and permanent type have high fitness and from the viewpoint of display-on-table type as a standard moving type was very convenient. The analysis of significant items at the characteristics of those display stores revealed that their locations, quality conservation, sanitation, users' convenience, designs and promotion are very important. The result of status analysis revealed that though there is a correlation among the types of display stores depending on the visiting season of tourists their installing is not desirable. Three types have been analyzed: Type 1 is a structure type only in the villages with continuous visitors, Type 2 a moving-table type only in the villages with temporary visitors and Type 3 is a fixed display-case type.

A single-clock-driven shift register and a two-stage buffer are proposed, using p-type, low-temperature polycrystalline silicon thin-film transistors. To eliminate the clock skew problems and to reduce the burden of the interface, only one clock signal was adopted to the shift register circuit, without additional reference voltages. A two-stage, p-type buffer was proposed to drive the gate line load and shows a full-swing output without threshold voltage loss. The shift register and buffer were designed for the 3.31" WVGA ($800{\times}480$) LCD panel, and the fabricated circuits were verified via simulations and measurements.

The fundamental purpose of this study is whether Show Window Display actually affect on purchase and if it does, how much Show Window Display have influence on the buyer's satisfaction. Show windows are most important at clothing stores. The show open types of domestic clothing stores are usually open-type and semi open-type. Show Window Display types of low and middle prices stores are generally opened, horizontal and storied type and the shape, height, opening type and use of ground floor are different by regional distinct features. Generally Show Window Display are consisted by lights, mannequins and directed props. In buying patterns, an impulse buying has more stronger effect than a scheduled buying, a substituted buying and non-buying. An impulse buying are strongly affected by Design and others are prices. The reason why Show Window Display affecting on purchase is the satisfaction of Design and the strong stimulus to purchase(impulse buying), and then Show window Display used by all components strongly has an effect on it. Factors of purchase desires were Design, price and quality in order and factors of purchase motivations were the motivation of clothing design and the motivation of impulse buying. Thus the effects of Show Window Display and factors of purchase motivations are same. As a result of this study, differentiated Show Window Display methods of clothing stores affect the value of goods, the stimulus of purchase and fostering sales effectiveness. Therefore the instruction of Show Window Display methods are indicated by this study.

Recently, white LEDs, especially, warm white LEDs have been intensively investigated due to outstanding optical properties, long term stability and low power consumption. In this study, mixed type and patterned type of remote phosphors were prepared by screen printing process employing green and red phosphor. Each type of remote phosphor exhibited distinctive photoluminescence spectrum. For example, the mixed type of remote phosphor exhibited unique spectrum, while the patterned type showed expectable spectrum depending on the concentration of phosphors. This indicates that a small amount of red phosphor dramatically reduced the green photoluminescence in the case of mixed-type remote phosphor, whereas the effect was negligible in the patterned-type remote phosphor. The possibility of undesirable chemical reaction was further investigated by using scanning electron microscopy and X-ray diffraction.
