Studies on display has been requested some major changes due to the high growth of the handheld terminal market. Therefore, the self emitting OLED(Organic Light Emitting Diode) has been interested as a next generation flat plane display because of its preeminent characteristics such as quick response characteristics, higher performance viewing angle, low power consumption, and panel floating. However, a trend of the display market is moving to three dimensional image processing instead of two dimensional flat display and various researches on display using hologram makes up for the difficulty in three dimensional display using typical flat display. In this study the Lenticular Screen Printing method is presented so that it can be applicable to organic semiconductor display devices and makes possible three dimensional display using flat display for complement the drawback of inorganic semiconductor.

각 분야에서 고화질 고해상도의 Flat Panel Display(FPD)에 대한 요구가 급증하고 있으며, FPD 소자들도 다양하다. FPD를 위한 구동방식은 근본적으로 matrix addroessing 방식을 사용하지만 FPD 소자의 동작 원리, 특성, 구동상의 문제점 등에 따라서 구동방식도 매우 다양하다. 다양한 FPD 소자들이 구동 방식과 구동회로를 다 살펴볼 수 없으므로 본고에서는 FPD소자인 PDP, EL, LED, EC, LCD, DMD, AMA, GLV, FED 등의 동작 원리를 설명하고, 이 소자들 중에서 AMLCD와 dc-PDP 소자의 구동방식과 구동회로에 대하여 논의한다. AMLCD의 구동방식으로는 펄스 구동 방식과 용량 구동 방식을 살펴보고, AMLCD의 문제점들을 극복할 수 있는 방법들을 설명한다. dc-PDP의 구동 방법인 pulse-memory 구동방식과 새로운 pulse-memory 구동 방식을 살펴보았다.

Recently, Plasma display panel(PDP) has been in the spotlight as one of the next generation flat-panel-display device. The luminance and luminous efficiency improvement is the hot issues for making a plasma display into a large flat panel device. In this paper, We suggest a new penning gas mixture, in order to find the optimum mixture gas in plasma display panel. The optimum gas composition has been found by the partial pressure of inert gases(such as Af and Kr added to matrix of He(70%)-Ne(27%)Xe(3%) and Ne(96%)-Xe(4%)). The influences of Ar or Kr addition to Ne(96%)-Xe(4%) and He(70%)-Ne(27%)-Xe(3%) mixture gases are experimentally investigated for AC Plasma Display Panel. When rare As(0.01%-0.03%) or Kr(0.01%-0.03%) is added Ne-Xe and He-Ne-Xe mixture gases, the luminance increases over 10%-20% and luminous efficiency increases over 10%-20% at 200 Torr. It is sure that luminance and efficiency are improved by Penning effect. Also, This influence of Penning effect is shown by increased wall charge(10%-25%). In addition to the result, firing voltage and minimum sustain voltage was approximately decreased by 2V-3V.

It is conducted that study on corner crack protection for various thermal environment in a flat panel display. Most of the consumer electronics consist of a plastic and a metal structure. And different properties of materials could cause failure of structural reliability due to the various operating temperatures. Especially for front bezel with thin and slender structure, the effect of temperature is significant, and the design for crack protection is crucial for thermal reliability of displays. In this study, it is prescribed the behavior of the front bezel in flat panel display for various operation temperatures and proposed design parameters to ensure the structural reliability of displays.

Amorphous silicon thin-film transtors (TFT's) have been designed and fabricated on glass substrates. The hydrogenated amorphous silicon (a-Si:H) thin-film has been deposited by decomposing silane(SiH4) in hydorgen ambient by rf glow discharge method. Amorphous silicon nitride(a-Si:H) has been chosen as the gate dielectric material. It has been prepared by decomposing the mixed gas of silane(SiH4) and ammonia(NH3). The electrical properties and performance characteristics of the thin-film transistrs have been measured and compared with the requirements for the switching elements in liquid crystal flat panel display. The results show that liquid crystal flat panel displays can be fabricated using the thin-film transistors described in this paper.
