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.

Transparent dielectric layer having color-filter function in front panel for PDP(Plasma Display Panel) was successfully fabricated and characterized. Transparent dielectric layer in front panel was made of glass based on $PbO-SiO_2-B_2O_3$ ternary system. The change of properties with content variation of oxide colorants in transparent dielectric layer having color-filter function was systematically accessed. It was demonstrated that the optimized content of oxide colorants to parent glass could greatly increase up contrast ratio and color temperature without significantly degrading luminance.

The advent of new media resulted in the revolutionary change of human way of life, which have big influence on the society and new culture other than that of the past appeared. This study aims preparing indicators of digital display space which meets with paradigm of the new age by studying characteristics of expression of new media in digital display space. his study searched for their meaning and possibilities by analyzing their characteristics of expression through cases of digital display space at homeand overseas since 1990s with key words of characteristics of expression of new media. Characteristics of expression in modern digital display space are characterized by immateriality, interrelated actions, nature of non-rectilineal figure, space is immaterial and abstract by new media, and new aesthetics completed by expression of images. Accordingly, we expect that this study will be the medium of development of digital display space which is developed more and communicated mutually by rapidly understanding changes of digital display space in the future.

Fabrication of photosensitive carbon nanotubes paste and its post-treatment has been developed for high resolution with good electron emission uniformity. We report novel post-treatment techniques including rubber-rolling and multiple field emission cycling from which we could improve the field emission properties of printed carbon nanotubes. These techniques would be easily applicable to large area field emission display using paste of carbon nanotubes

In order to improve the contrast ratio of PDPs in the bright room, we decreased the panel reflection by coating phosphors with pigments. In this work, we investigated the panel reflectance with various sizes of the blue pigments and obtained good results by reducing the size of the pigment properly.

We developed three kinds of electrode-structures for high luminance and luminous efficiency. Also, we optimized the mixture gas. Three kinds of 7.5-inch experimental panels having a pixel pitch of 0.864mm were evaluated, and high efficiency of 1.6lm/W was obtained in the panel type2.

Though bottom emission AM-OLED has advantages in respect of mass production, the bottom emission type is underrated due to its low aperture ratio and low color gamut, compared with top emission type. In this paper, we demonstrate that the color gamut up to 89 % can be simply achieved by depositing dielectric multilayers, whose thicknesses are determined using an optical simulation program, prior to formation of Si layer.

We propose a novel digital driving method for AM-OLED (Active Matrix-Organic Light Emitting Diode) display. Proposed method modulates $V_{DD}$ so that luminance may be weighted in accordance with the bit significance. We can increase the minimum emission time or slower scan circuits are applicable by using proposed method.
