- Title:Thermal Transfer Pixel Patterning Method by General Lamp Source in Organic Light Emitting Devices
- Hyeong Woo Bae, Gyeong Heon Kim, and Jang Hyuk Kwon (Kyung Hee Univ., Korea)
Abstract: We report the result of sublimation based thermal transfer method by using general light source. Several thermal transfer donor substrates were designed and fabricated for our thermal transfer process.?Organic material on the donor substrate is locally heated and evaporated by the patterned layer. From this process, we obtained emissive layer patterns under 100 ¥ìm size. To verify this process, we fabricated the red phosphorescent OLED devices. Device performances were compared with those of our thermal deposition processed device, driving voltage increase at 1,000 cd/m2 is 0.7V and the maximum current efficiency decreases about 8 cd/A
