“…1) These devices are fabricated by various patterning methods using organic materials, such as mask evaporation, screen printing, 2) stamping, 3) masked dye diffusion, 4) ink-jet printing (IJP), [5][6][7][8][9][10][11] microgravure printing, 12) spraying, 13) ink brushing, 14) and lamination. [15][16][17] One of the interesting topics is the fabrication of transparent OLEDs (TOLEDs) that emit from two sides, and their type of matrix panel has been demonstrated. 18,19) However, an image of such display devices can show a flip horizontal shape and the result is limited to few applications.…”
