  • To get rid of cell assembly margin and have more process room of upper substrate, we developed truly COT (Color Filter On TFF Array) LCDs in that B/M (Black Matrix) as well as C/F (Color Filter) layer is located on TFT substrate. Novel B/M material is also developed for this COT structure. Difficulty in making contact hole through C/F layer was solved by making each C/F pattern isolated from others. We think this configuration will be core technology for prominent COT LCDs.

  • In contrast to conventional crystalline cells, back-contact solar cells feature high efficiencies, simpler module assembly, and better aesthetics. The highest commercialized cell and module efficiency was recorded by n-type back-contact solar cells. However, the mainstream PV industry uses a p-type substrate instead of n-type due to the high costs and complexity of the manufacturing processes in the case of the latter. P-type back-contact solar cells such as metal wrap-through and emitter wrap-through, which are inexpensive and compatible with the current PV industry, have consequently been developed. In this paper the characteristics of EWT (emitter wrap-through) solar cells and their status and prospects for development are discussed.

  • 본 논문은 LS산전 고압인버터의 국내외 현장 전용화 사례에 대해 기술한다. 고압인버터는 대용량 고전압 전동기를 구비한 중요부하에 주로 적용되며 단독운전보다는 다수의 고압인버터가 연동 운전하는 현장에 설치되는 경우가 많다. 이러한 현장에는 표준제품이 아닌 전용화 기능을 포함한 제품이 출하가 된다. 자사 LS MVD는 각종 산업설비와 국책연구기관의 시험설비 그리고 발전소 수처리 시설 등 국가기간시설에 많이 적용이 되며 매년 70여대 이상의 MVD가 국내외 전동기 부하에 신규로 설치되어 운용되고 있다. 본 논문에서는 주목할만한 현장의 전용화 사례에 대해 설명하여 향후 고압인버터를 적용하고자 하는 고객이나 고압인버터에 관심이 있는 엔지니어에게 고압인버터에 대한 이해도를 높이고자 한다.

  • To increase the performance of the light diffusion films, we controlled the three dimensional microstructure of the organic fillers(beads). The refractive index, the size distribution and the three dimensional distribution of beads play an important role to determine the performance of light diffusion films for the backlight unit of TFT-LCD.
