  • The conventional AC PDP has a relatively low efficiency which is close to 1.5 lm/W. If the AC sustain period is replaced by the RF sustain period, due to oscillating and low electric field, almost 60% of the supplied energy is spent by Xe excitation [1]. The efficiency of RF PDP can be $4{\sim}5$ times higher than that of AC PDP. In this paper, we will present the RF PDP that is a new type of PDP. A new display method in PDP using RF pulses is suggested and applied on a 4-inch-diagonal Panel (hereinafter 4" panel). Even though there were many researches in RF discharge, there was not enough research for display application. Now we propose the RF PDP that is a new display field and we will expect to do more research in this field.

  • The virtual reality technology has been developed as the computer and computer graphic technology are progressed. However it has still the limits of the use because of it costs a great for system construction. A virtual reality technology is the best application example to reduce time and cost of development in engineering. Actually, VR(Virtual reality) technology has given engineers the ability to design, test and evaluate engineering systems in a virtual environment. The objective of this paper is to construct the arm mounted display VR system by using 3 channel spherical screen and to show its capabilities of an engineering system development. This paper describes the development of arm mounted display VR system with 3 channel spherical screen system and the generation of 3 channel graphic modules. The arm mounted display VR system provides a highly economical efficiency because of it uses a popular computer system as a graphic server.

  • There are several researches on 2D gaze tracking techniques for the 2D screen for the Human-Computer Interaction. However, the researches for the gaze-based interaction to the stereo images or contents are not reported. The 3D display techniques are emerging now for the reality service. Moreover, the 3D interaction techniques are much more needed in the 3D contents service environments. This paper addresses gaze-based 3D interaction techniques on stereo display, such as parallax barrier or lenticular stereo display. This paper presents our researches on 3D gaze estimation and gaze-based interaction to stereo display.

  • The display of biological signals in raster scan monitors often involves a multirate sampling operation which consists of decimation .and interpolation. All electroencephalouaphic (EEG) samples of 10 to 30 seconds (2, 500 to 7, 500 samples at 250[Hz] sampling frequency) must be displayed in the computer screen to keep the aspect ratio of the paper polygraph output. Since the current afrorclable display technology Plots at most 2, 000 Pixels Per row, sDme signal samples need to be discarde4 This Paper studies methods to perform this operation characterizing them from the signal processing viewpoint and compares the display quality among several decimation techniques. Experimental results show that a nonlinear operation such as the peak detection method could be preferable to the canonical linear filtering to reduce aliasing.

  • The commercialization of an active matrix e-reader display using E Ink microencapsulated electrophoretic (MEP) ink marked a big step towards comfortable reading over an extended period of time in an electronic book, as the high resolution display, jointly realized by Philips, E Ink and Toppan, has a true paper-like look and feel. Alternative electrophoretic material systems are being developed by SiPix and Bridgestone and progress has been made in the past two years. In this paper, electrophoretic material systems are briefly reviewed, after which the perspectives and challenges of electrophoretic displays are addressed and methods for generating gray tones are presented and discussed.

  • Electro-wetting display (EWD) that displays information by controling movement of fluid is one of the strong candidates for electronic paper display (EPD). In EWD cell. the movement of oil which locates between hydrophobic insulation layer and deionized water is rather random, which makes it difficult to realize gray scale, fast response time, and good color characteristics. In this paper, we investigated how to control the oil movement in specific one direction by surface treatment and pattered electrodes. From these experiments, we could control oil movement in a desired direction.

  • We successfully fabricated flexible electronic paper display (EPD) by using toner particles on plastic (PC) substrate. It has high resolution (WVGA : 800 ${\times}$ 480) and 7 inch diagonal viewable image size. The response time was about 0.25 msec at 90 V, a contrast ratio of about 2, a driving voltage of 60 V which we successfully demonstrated to display several images at.

  • Optically anisotropic rotating balls were disposed in a monolayer, and controllably closely packed with respect to one another in the monolayer. The close packed monolayer configuration provided high brightness and improved contrast. The monolayer rotating ball display (MRB) electrically demonstrated a fast response time of approximately 40 msec at a voltage of 30 V. Measurements of the rotation as a function of voltage led to surface charge density for the balls in the range of 3-4 ${\mu}C/m^2$.

  • There is mounting evidence that complex computer system displays in control rooms contribute to cognitive complexity and, thus, to the probability of human error. Research shows that reaction time increases and response accuracy decreases as the number of elements in the display screen increase. However, in terms of supporting the control room operator, approaches focusing on addressing display complexity solely in terms of information density and its location and patterning, will fall short of delivering a properly designed interface. This paper argues that information complexity and semantic complexity are mandatory components when considering display complexity and that the addition of these concepts assists in understanding and resolving differences between designers and the preferences and performance of operators. This paper concludes that a number of simplified methods, when combined, can be used to estimate the impact that a particular display may have on the operator's ability to perform a function accurately and effectively. We present a mixed qualitative and quantitative approach and a method for complexity estimation.
