“…For the purpose of a simple device process, good long-term stability with identical device characteristics, we have studied the OLEDs with a mixed single-layer (MSL), [26][27][28][29][30][31][32][33][34][35][36][37] application to a special solution-processed OLED, 29,[38][39][40][41][42][43] using inkjet printing technology, [44][45][46][47][48][49][50] and the OLED fabricated with spray method. 51,52) In order to express multi-functional abilities of the organic materials, we have studied a doublefaced emission panel with different images, named a "Dual-Drive Emission (DDE) panel", 53,54) an organic light-sensing device 55,56) and X-ray sensing devices, 57) a stacked device structure of OLED and light-sensing devices, named "Bifunction Matrix Array (Bi-Matrix)", 58,59) multi-function devices with single organic device structure, [60][61][62][63][64][65] and an organic-scanner with the OLED as a light source. 66) A brief description was presented in the open session, the 24th microoptics conference, MS-2.…”
