We have developed the technique of fabricating triode structure with simple stacking method using a polymer insulator that is suitable for large panel and the activation method after the fabrication. By the techniques, a test panel was manufactured and proves good emission property and uniformity.

We have demonstrated a flexible and full-color OTFT-OLED display. The display has a top-emitting pixel structure with a resolution of 80 ppi, which can be achieved by developed integration architecture of OTFTs. The 0.3-mm-thick flexible display exhibits peak brightness over 100 nit with a contrast ratio greater than 1000:1.

We have developed a flexible OTFT backplane in which all the dielectrics are formed by solutionprocess in order to achieve low-cost and highthroughput manufacturing. The backplane successfully drives a flexible AM-OLED display with peak brightness of > 200 nit and the contrast ratio of > 1000:1 with great mechanical flexibility.

We developed the laser annealing system using green laser of 261W(5kHz) and 75.5mJ/pulse(2kHz). We confirmed that this system makes it possible to form two kinds(large or uniformed grain) of poly-Si by changing its polarized directions. By using ${\mu}-crystal-Si$ as irradiated films, grain size uniformity is better than that using a-Si.

The aim of present study was to examine the inhibitory effects of hydroxamic acid derivatives on the melanogenesis. We found that hydroxamic acid moiety was important for anti-melanogenic activity. Compounds 1a and 1b strongly inhibited melanin synthesis via deactivation of tyrosinase. Hydroxamic acid has metal ion chelating ability which is similar to that kojic acid, however, anti-tyrosinase mechanism of compounds 1a and 1b was different from that of kojic acid. They showed noncompetitive inhibition kinetics
