Both PM-OLEDs and AM-OLEDs are now in production. However, manufacturers are still concerned about life-time, voltage drift, operating voltage and efficiency in order to develop larger displays. Most material suppliers seem to be focussing on emitters and the benefits of introducing suitable charge transporters have been largely unexplored. OLED-T has developed a novel organic electron injector (Trade Name: EI-101) which evaporates at a very low temperature of $300^{\circ}C$ as opposed to the conventional LiF which requires $580^{\circ}C$. EI-101 has been found to increase the lifetime by up to 12%, reduce the voltage drift by up to 61% and increase the efficiency by up to 15%. The material can be handled in air and in situ Q-mass spectroscopy on extended thermal evaporation has confirmed its high stability for use in mass production.

The biological effects of NADPH-dependent isocitrate dehydrogenase (IDPc) inhibitor. DA-11004, was examined in obese zucker rats or streptozotocin-induced diabetic SD rats. Diabetes was induced by injection of streptozotocin (50mg/kg) dissolved in citrate buffer (pH 4.8) into the tail vein and induction of diabetes was confirmed by the measurement of the tail blood glucose level at 48h. DA-11004 (30mg/kg, po) was injected for successive 7days and significantly reduced the plasma glucose in streptozotocin-induced diabetic rats (P<0.05). (omitted)

The biological effects of NADPH-dependent isocitrate dehydrogenase (IDPc) inhibitor, DA-11004, was investigated in obese diabetic (ob/ ob) mice. DA-11004, metformin, and oxalomalate were daily injected (ip) for 8 weeks and after completing an 8-week period of experiment, mice were sacrificed at 1 hr after the last drugs treatment to collect their blood, liver, and adipose tissues(epididymal and retroperitoneal fat).

Recently. it has been known that NADPH-dependent isocitrate dehydrogenase (IDPc) involves in the obesity through production of NADPH, an important cofactor. DA-11004 is a synthetic potent IDPc inhibitor that $IC_{50}$ for IDPc is 1.49$\mu\textrm{M}$ (0.9$\mu$g/ml). The purpose of this study was to evaluate the effects of DA-11004 on the high fat high sucrose (HF)-induced obesity in C57BL/6 mice. (omitted)

A touch screen panel embedded 12.1-inch TFT LCD employing a standard a-Si:H TFT process has been successfully developed. Compared with conventional external touch screen panels, the new internal TSP exhibits a clearer image and improved touch feeling. Our new internal proposed TSP can be fabricated with low cost.

We have developed a RGB polymer dispersed liquid crystal film (RGB PDLC). To obtain the color display, color pigments are mixed in the prepolymer. We have presented an electro-optical performance of our cell and analyzed the electro optical properties for varying LC/ pre-polymer ratio and polymer type.

One-Drop-Filling (ODF) process is an advanced vacuum filling process in LCoS manufacture line. The merits not only increase the throughput of liquid crystal filling process but also reduce the number of equipments. Studying application of ODF process in LCoS panel manufacturing is the purpose of is this article. The accuracy of liquid crystal drop size, the stability of seal dispensing and the nozzle size etc. In the tiny panel manufacture are more important than those factors in normal panel manufacture.

In this paper, a new barrier rib forming method of embossed barrier rib (EBR) formation process for the PDP rear panel was introduced. The process is mainly composed of green sheet fabrication, lamination of the green sheet on the rear glass panel having data electrodes, and roll embossing followed by firing. The EBR process has two advantages over the conventional barrier rib forming methods. One is the process requires less equipment investment than the conventional methods by about 20% of the current rear panel fabrication equipment investment owing to the simplified fabrication process. The other advantage is its reduced rear panel manufacturing cost by eliminating the time consuming and complicated processes and waste of materials in the conventional methods. In this study, general procedure of EBR fabrication process is described and the characteristics of prototype PDP using EBR panel are discussed.
