Transparent LED display is providing city residents with different attractions via information services and landscape and increasing demand is detected in various areas. It is true that majority of the current demand in transparent electrode material was found and used in ITO but limitations in capacity and economic efficiency led to the need for continuous research and technology development via new materials. As a new material, metal mesh has 85% of the materials to substitute ITO and is widely used due to low-cost and high-conductive rate. Maintenance of transparent LED display utilizing metal mesh compared to existing ITO transparent display is much easier as it not only saves resources but is also economical. Thus the objective of this paper lies in proposing the utilization of metal mesh in transparent LED display prototype to enable economical use of transparent LED display technology and to expand the market and to also propose transparent LED display development method via metal mesh and manufacture a prototype based on the method. And a characteristic comparison test between ITO and metal mesh provides the possibility of using metal mesh as a transparent electrode material in transparent LED display development.

The composites were fabricated with titania used commercially and calcite as a filler in BZB glass matrix and their thermal, optical and electrical properties were investigated. From our results, calcite may be the profitable and highly efficient reflectance material as a filler for flat panel display devices.

Cell gap dependence on anisotropic phase separation was studied. The results showed that the morphology of phase separation depended on cell gap and material parameters. With numerical simulation and experiments, the optimal range of cell gap in the formation of polymer layer and liquid crystal was suggested for given material parameters.

Electrowetting display (EWD) is one of the strong candidates for electronic paper like display (EPD). However, in the conventional EWD, the oil movement occurs in random direction so that we can observe irregular distribution of contracted oil in the operation. To realize colorful display and achieve a fast response time, oil movement in the pixel should be directed in a specific direction. In this paper, we report the result of oil contraction with specified direction which is achieved by patterned electrode. From the experiments, we find that the oil movement depends on the portion of etched electrode area and study other influencing factors of patterned electrode on the oil movement.

We report on white organic light-emitting diodes (WOLEDs) based on single white dopants, $Ir(pq)_2$($F_2$-ppy) and $Ir(F_2-ppy)_2$(pq), where $F_2$-ppy and pq are 2-(2,4-difluorophenyl) pyridine and 2-phenylquinoline, respectively. The similar phosphorescent lifetime of two ligands lead to luminescence emission in two ligands simultaneously. However, the emission color of the devices was reddish, because the energy was not transferred efficiently from the 4,4,N,N'-dicarbazolebiphenyl (CBP) to the $F_2$-ppy ligand, due to the small band gap of the CBP. Accordingly, we used 1,4-phenylenesis(triphenylsilane) (UGH2) with a large band gap, instead of CBP as the host material. As a result, it was possible to adjust the emission color by the host material. The luminous efficiency of the device with $Ir(F_2-ppy)_2$(pq) doped in UGH2 was about 11 cd/A at 0.06 cd/$m^2$.
