  • The recent growth in the portable display industry has been dominated by flexible display, moreover, several developing of using LCD technology has been in making the flexible display work effectively, however flexible device is not practical. Recently, the study on the multi-display screen has been published as the needs of larger screen in mobile device has been increased. The multi-display screen which is composed of two LCD panels, has the characteristics of the seamless gap between two panels. To meet the needs of this multi-display, in this paper, the study is performed to design the seamless device which consist of LCD panels, light film, back light and driver, and finally, we evaluated the effectiveness of seamless folding mechanism.

  • A mini-projector prototype employing a LED light source, a nontelecentric structure, and an LCOS panel for application in the integrated 3D display was fabricated. A seamless image was obtained by tilting an array of mini-projectors. Seamless quality was created by the excellent uniformity of the projection intensity on the mini-projector's screen, which was simulated as 98.34%. Great uniformity can be realized by optimizing the design of the light source and the optics configuration, which is the key to such realization.

  • The 3D display has been used in optical projection technology to connect twenty mini- projectors with seamless image tiling. In this way, we can improve the projected resolution by reducing each project screen and increase projected area by connect several mini-projectors. In this article, the illumination system uses the LED light source, non- telecentric structure and LCOS panel, and it's total length is less than 10 centimeter. It can build a seamless large display by tiling multiple projectors.

  • The needs of larger screen in mobile device would be increased as the time of ubiquitous and convergence is coming. And, the type of mobile device has been evolved from bar, slide to row. Recently, the study on the multi-display screen which has seamless gap between two display panel has been published, and moreover the System On Chip(SOC) design strategy of core chip has been the most promising Field-Programmable Gate Array(FPGA) technology in the display system. Therefore, in this paper, we proposed the design technique of SOC and evaluated the effectiveness with Very high speed Hardware Description Language(VHDL) Intellectual Property (IP) for the operation of multi display device driver. Also, This IP design would be to allow any kind of user interface in control system.

  • 3D stereo display systems gain more interests recently. Multiple-view autostereoscopic display system enables observers to watch stereo image from multiple viewpoints not wearing specific devices such as shutter glasses or HMD. Therefore, the Multiple-view autostereoscopic display is being spotlighted in the field of virtual reality, mobile, 3D TV and so on. However, one of the critical disadvantages of the system is that observer can enjoy the system only in a small designated area where the system is designed to work properly. This research provides an effective way of GPU based rendering technique to present seamless 3D stereo experiences from an arbitrary observer's view position.

  • This study presents a strategy using the synchronized output regulation method (SOR) for controlling inverters operating in stand-alone and grid-connected modes. From the view point of networked dynamic systems, SOR involves nodes with outputs that are synchronized but also display a desirable wave shape. Under the SOR strategy, the inverter and grid are treated as two nodes that comprise a simple network. These two nodes work independently under the stand-alone mode. An intermediate mode, here is named the synchronization mode, is emphasized because the transition from the stand-alone mode to the grid-connected mode can be dealt as a standard SOR problem. In the grid-connected mode, the inverter operates in an independent way, in which the voltage reference changes for generalized synchronization where its output current satisfies the required power injection. Such a relatively independent design leads to a seamless transfer between operation modes. The closed-loop system is analyzed in the state space on the basis of the output regulation theory, which improves the robustness of the design. Simulations and experiments are performed to verify the proposed control strategy.

  • This paper presents the method to provide a fast service for user in image manipulation such as zooming and panning of huge size high resolution satellite image (e.g. Giga bytes per scene). The proposed technique is based on the hierarchical structure that has 3D-Tiling in horizontal and vertical direction to provide the image service more effectively than 2D-Tiling technique in the past does. The essence of the proposed technique is to create tiles that have optimum level of horizontal as well as vertical direction on the basis of current displaying area which changes as user manipulates huge image. So this technique provides seamless service, and will be very powerful and useful for manipulation of images of huge size without data conversion.
