  • This work proposes and characterizes switched-capacitor type cyclic digital-to-analog converter for display data driving. The proposed digital-to-analog converter composes simple structure, and can be implemented for low-power, small area display driver ICs. By circuit level simulations, it is verified that the op-amp input referred offset is attenuated at the DAC output and the circuit performance is robust at 0.5% of capacitor mismatch.

  • The one of the most meaningful change in the recent ubiquitous environment is the omnipresence of public digital display device for providing ubiquitous information. It is the important issue to provide publicity as well as adaptive information to each user in the field of the public digital display device. This research proposes the idea ensuring fast response speed by the selection of user preference function. The preference function is selected by statistics using Zipf distribution in the system comprising mobile device and digital display device based on NFC (Near Field Communication). The idea is proved by CPM-GOMS model and the improvement of user response can be achieved.

  • This paper presents a brief introduction to self-interference incoherent digital holography (SIDH). Holography conducted under incoherent light conditions has various advantages over digital holography performed with a conventional coherent light source. We categorize the methods for SIDH, which divides the incident light into two waves and modulates them differently. We also explore various optical concepts and techniques for the implementation and advancement of SIDH. This review presents the system design, performance analysis, and improvement of SIDH, as well as recent applications of SIDH, including optical sectioning and deep-learning-based SIDH.

  • Our human society is rapidly changing into the world of advanced visual information with the development of image industry, the advent of satellite and terrestrial DMB, and the opening of Ubiquitous era. Like this, we are living in the space of overflowing media contents. Jean Baudrillad anticipated that the influential power of image would dominate our reality in 'Simulation'. Noticing the indication of our time, which is organized by various information media including the mass media, Baudrillad predicted that the 21st century would be an era of symbol and image due to the development of television, computer, and internet. This paper attempts to find the physical and conceptual peculiarities of the space change according to the use of display, by analyzing SF films, where future daily life is a major setting, under the judgement that the exploration of space change is significant. Through findings, it tries to lead the visual expansion, which recognizes display as space itself rather than object of space and changes unmoving space into moving space, and suggest the future space design by using digital space. It suggests case studies, which use digital display in the real space, as a study method and it examines the features, influences, and roles of digital display through investigating literatures and cases. In addition, it attempts to find a correlation of digital display and space by selecting films, which can give the affluent resources of analysis on the digital display among SF films. Therefore, it will come to a conclusion that space change should be dealt with in the space design.

  • Head fixed type multi-focus display system using Galvano-scanner and DMD(Digital Micro-mirror Device), which is able to perfectly accommodate, can solve eye fatigue due to conflict between convergence eye movement and accommodation action in stereoscopic display. This system is able to accommodate through making convergence point about each view point and offering it in front of observer's pupil by using laser scanning method. In this paper, we analyzed laser scanning method of this multi-focus display system. And multi-focus display system based on this analysis was made, which showed that focus adjustment was possible through video camera. As a result, formation principle of view point of multi-focus system by laser scanning method was verified.

  • We have demonstrated efficient white WOLEDs by using three emissive materials for primary colors (red, green, and blue). The characteristics of WOLEDs showed the maximum luminance of $37600\;cd/m^2$ at 13V, the maximum luminous efficiency of 20.6 cd/A, and the $CIE_{xy}$ coordinates of (x = 0.33, y = 0.33) at 10V.

  • An experimental study was made to compare digital display with analogue-digital display during a digital pursuit tracking task under the preview information. The effect of preview on performance during the tracking task was analyzed for the different preview spans and the different characteristics of the information input. The data from ten subjects revealed that the RMS error performance was improved substantially in the case of one preview point than in that of no preview. It was obtained from the result of the experiments that the improvement ratio of analogue digital to digital display increased to 48%.
