dc.description.abstract | In this work, characteristics of microplasma for enhancement of efficiency and reliability of flexible photoluminescent display was investigated. For enhancing the efficiency of microplasma, the microplasma modes generated in a plasma display with a coplanar-gap and an auxiliary electrode were investigated using the discharge current peak time (discharge delay) and discharge current. From the measurement results of the discharge current peak time and discharge current, three types of modes were classified as follows: mode 1 showed a decrease in both the discharge current and the discharge delay, mode 2 showed a decrease in the discharge current and an increase in the discharge delay, and mode 3 showed an increase in the discharge current and a decrease in the discharge delay. In addition, to illustrate the phenomena of the three microplasma modes generated in a coplanar- gap with the auxiliary electrode, discharge models were suggested using the wall charge state and field effect. From the measurement of IR spectra of 823 and 828nm, the infrared (IR) efficiency increased in modes 1 and 2 with an increase in the auxiliary pulse voltage. However, in mode 3, the IR efficiency started to decrease. According to the measurement results, modes 1 and 2 are suitable for microplasma generated in a coplanar-gap with an auxiliary electrode to obtain high efficacy. For more detailed investigation, the characteristics of the discharge modes in microplasma generated in a plasma display with a coplanar gap and an auxiliary electrode were investigated in accordance with various plate gaps in the range of 200 to 1,000 $\mu m$ and coplanar gaps in the range of 220 to 2,000 $\mu m$. The measurement results of the discharge current peak time, discharge current, and luminous efficacy showed that, mode 2 and mode 3 appeared in microplasma in cases of various plate gaps and coplanar gaps and that the luminous efficacy increased in mode 2 and decreased in mode 3.
