  • In this paper, we proposed the novel device and process design to enhance the uniformity of low-temperature poly-Si TFTs fabricated by sequential lateral solidification (SLS). The proposed design schemes can avert the conventional two-shot SLS process-induced issues. Moreover, different design considerations between conventional excimer laser crystallization and the SLS process were also proposed and discussed.

  • The contact resistivity of the black interlayer which has been introduced between BUS and ITO electrodes in a plasma display panel was evaluated using two kinds of specially designed test electrode patterns. Of the two, type 2 pattern was able to evaluate the contact resistivity more successfully, which was calculated as about $250{\Omega}$ in the suggested test pattern structure.

  • A low cost PDP sustain power supply is proposed based on flyback topology using Boundary Conduction Mode(BCM) to control input current regulation. This method guarantees DCM condition to regulate the input current harmonics under all load conditions. An excessive voltage stress due to the link voltage increase can be suppressed by removing link capacitor and adjusting transformer turns ratios, which makes it possible to be used for universal line applications. The proposed converter is tested with a 400W(200V-2A output) prototype circuit.

  • This paper classifies driving technologies for AMOLEDs by the driving TFT conditions in pixels. A saturation region operation type driving TFT circuit provides good stability of OLED because of constant current drive. However, complicated compensation circuits are necessary to avoid effect of the TFT characteristics deviation. On the other hand, a linear region operation type driving TFT circuit provides better uniformity of the display image and lower power consumption. However, the stability of OLED is critical because of constant voltage drive.

  • The problem of the conflict between eye convergence and accommodation can be induced at Stereoscopic or multi-view 3D display system using binocular disparity. A multi-focus 3D display system was developed, which can solve the problem. LEDs are used instead of galvano scanner and laser to avoid mechanical moving part at the 3D display system.

  • High Luminance PDPs have been developed using high efficient electrode structure, discharge gas and fishbone type barrier ribs. New phosphors for the good picture quality were developed. Also, New manufacturing processes such as CPBB were applied in order to reduce processing steps. High Luminance of 1,000 $cd/m^2$ was obtained in the series of 42 inch, 50 inch and 60 inch PDPs.

  • This study is focused on proposing a creative system that can display 3D hologram on the real-time basis. This method applies 3D display on volume hologram based on CGH. The process of implementing the system consists of two stages of fringe pattern recording for passive component that includes information on hologram, and irradiating object beam. Distinguished from an existing electronic holographic display system, this system is free from the process of a huge calculation that is necessary to compose CGH for a real-time 3D display.

  • A glass cockpit is an aircraft cockpit that features electronic (digital) instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges to display information, a glass cockpit uses several displays driven by flight management systems, that can be adjusted to display flight information as needed. This study introduces design considerations of electronic display in KAS Part 23 airplanes.

  • Laser diagnostic method in a plasma display discharge cell was introduced. The information of electric field, potential and electron temperature et al. in the surface of plasma display panel can be measured using laser induced fluorescence spectroscopy. However, because of the very small discharge dimension of ${\sim}$ 100 ${\mu}m$, the measurement attempt has almost not been performed. In this paper, the direct measurement possibility of the parameters and the recent work of electric field measurement are demonstrated in the plasma display panel.
