Flexible displays such as plastic based LCDs and organic light-emitting diodes for mobile communication devices have been researched and developed at KETI in KOREA since 1997. The Plastic film substrate has so poor thermal tolerance and non-rigidness that the fabrication of active devices and panel assembly have to perform at low temperature and pressure. In addition, high thermal expansion of the substrate is also a serious problem for reliable metallic film deposition. In this paper, we investigated particularly on the fundamental characteristics of various plastic substrates and then, suggested novel methods that improve the fabrication processes of plastic LCD panel. In order to maintain stable substrate surface and uniform cell gap during panel assembly, we utilized newly-invented iii and vacuum chuck. Electro-optical characteristics of fabricated plastic LCD are better than or equivalent to those of typical glass based LCDs though it is thinner, lighter-weight and more robust.

현대 사회가 고도의 정보화 사회로 변화하는 가운데 능동행렬 액정 표시 소자(AMLCD : Active Matrix Liquid Crystal Display)는 정보 디스플레이 분야에서 없어서는 안될 중요한 위치를 차지하게 됐다. AMOLED는 자체발광형이므로 LCD에 비해 시야각, contrast, 시인성이 우수하며, 화소를 낮은 전류 밀도로 구동시킨다는 장점이 있다. OLED 소자는 각 화소를 구동할 수 있는 박막 트랜지스타가 필요하며, OLED 소자와 결합된 TFT의 연구도 진행되고 있다. 더욱이 모바일 소자에서 낮은 구동 전압과 비용의 절감을 위해 System On Panels (SOP)에 대한 연구가 또한 진행되고 있다. LCD 패널위에 콘트롤러와 메모리와 같은 소자를 직접화시킴으로써 액정 표시 장치를 소형화시킬 수 있으며 신뢰성을 향상시킬 수가 있다. 본 연구에서는 SOP를 위한 ELA 방법을 통하여 결정화한 poly-Si TFT memory를 제작하여 전기적 특성을 조사하였다.

Recently low resistance of bus line is required for large screen size TFT-LCD panels. As a result, lower resistance Al-alloy is currently reviewed extensively. The resistivity is required smaller than 10 $\mu$$\Omega$cm. In this paper, Al-Nd thin film were deposited on glass substrates by D.C. magnetron sputtering system under various condition. Its properties were characterized by SEM, AFM, XRD, 4-ping-probe. The optimal condition of Al-Nd was 12$0^{\circ}C$, 125W, 0.4Pa, 30sccm(Ar) and 35$0^{\circ}C$, 20min. annealing. At that condition the resistivity of Al-Nd(2wt.%) was about 4 $\mu$$\Omega$cm. The minimum contact resistance of ITO/Nd was about 110$\mu$$\Omega$cm in the condition of 30$0^{\circ}C$, Ar 30 sccm.

Recently low resistance of gate line or data line is required for large screen size TFT-LCD panels. As a result, lower resistance Al-alloy is currently reviewed extensively and the resistivity is required smaller than 10$\mu\Omega$cm. In this paper, Al-Nd and Al-Zr thin film were deposited on glass substrated by D.C. magnetron sputtering system under various condition. Its properties were characterized by SEM, AFM, XRD and 4-point-probe. The optimal condition was $120^{\circ}C$, 125W, 0.4Pa, 30sccm (Ar) and $350^{\circ}C$, 20min. annealing. At that condition the resistivity of Al-Zr(0.9%wt.) is about 4$\mu\Omega$cm.

Recently, research on a flat panel display(FPD) has focused on organic light-emitting display(OLED) which has wide angle of view, high contrast ratio and low power consumption. ITO(Indium-Tin-Oxide) films are the most widely used material as a transparent electrode of OLED and also in many other display devices like LCD or PDP. The performance and efficiency of OLED is related to the surface condition of ITO coated glass substrate. The typical surface defect of glass substrate is measured for electric characteristics and physical condition for transmittance and roughness. Since ITO coated glass substrate can be destroyed for inspection about surface roughness, sheet resistance, film thickness and transmittance, precise fabrication condition should be made based on the estimated relationship. In this paper, ITO films were prepared on the commercial glass substrate by the Ion-Plating method changing the partial pressure of gas(Ar, 02) and the chamber temperature between $200^{\circ}C$ and $300^{\circ}C$. The characteristics of films were examined by the 4-point probe, supersonic thickness measurement, transmittance measurement and AFM. We estimated the relationship between processing parameters(Ar gas, O2 gas, Temperature) and properties of ITO films (Sheet Resistance, Film Thickness, Transmittance, Surface Roughness).

We have prepared a DEMO conveyor device for conveying a large 8G class glass sheet using ahorizontal air-cushion system. This device consists of the body frame and the driving frame that are combined to realize a frame for conveying glass without any contact.The driving frame comprises an air flotation table (bed), drive roller supported at both ends, and ASU. Part of the ASU serves to control the airflow as the chamber consists of a porous pad and fan. Fiber filters replace the porous pad and axial fans serve as an air compressor. In addition, to determine the appropriate glass levitation from the air table, this study examined the design specifications of the applied filter (discharge speed of HEPA and ULPA filters, and flow rate) as well as the height of the and the proper supporting roller height (14mm). Then, after adjusting the position of the ASU and the number of ASUs required to configure the UNIT air floating C/V, we analyzed the height and flatness of the glass and derived the appropriate layout (1140-mm distance between ASUs).

An Parallax-Barrier type autostereoscopic display system is implemented to overcome the handicap of current glass-typed stereo imaging system which gives operators unnatural feeling and reluctance. This system is composed of image mixing part of two input images, A/D transformation part, scan conversion part to eliminate the rainbow interference phenomenon, and pin-hole type barrier lens. For the fine display the accurate slit width of barrier is calculated in consideration of retina size, and the samsung 10.4" TFT-LCO was used as flat display monitor.itor.
