本研究以適用於量產的網版印刷技術為基礎，開發能在室溫下、大氣環境中、於可撓式軟性基板上製作低表面粗糙度之崁入式金屬網格透明電極的製程技術。為了進一步降低電極表面粗糙度及增加元件應用時之電流擴散效應，在銀網電極表面使用導電高分子PEDOT:PS S作為修飾平坦層，此層同時具有降低OLED元件應用時可能的漏電流及短路現象。本研究所獲致之軟性銀網性質檢測結果顯示，無論是透光度、片電阻、表面粗糙度、抗彎曲機械等特性皆優於ITO電極；以此透明電極，作成性質之白光OLED元件，其電性與發光特性皆不遜於ITO電極。;This study aims on developing a scalable, screen-printing based process for fabricating low surface roughness, embedded metal-mesh transparent electrode on a flexible substrate. This method takes the advantages that all fabricating processes are exectable at room temperature and in the ambient environment. To further reduce the the electrode’s surface roughness and increase the effect of current diffusion during the device’s lighting process, a surface modification layer of conducting polymer, PEDOT:PSS, is used. This layer also helps to impede current leakage and avoid short circuit at the lighting duration. Measurements show that the obtained embedded silver-mesh electrode has excellent properties in transmittance, sheet resistance, surface roughness, and mechanical bending characteristics, superior to that of ITO electrode. As serving as the anode in a white OLED device, the present metal-mesh based device also demonstrates better electrical and luminescent characteristics than that based on the ITO electrode.
