Methods of making a full-color organic light-emitting display |
摘要 |
Methods of making a full-color organic light-emitting display are disclosed. The methods include ink-jet printing of fluorescent dopants selected to produce red, green, or blue light emission from designated subpixels of the display. The dopants are printed sequentially from ink-jet printing compositions which permit printing of dopant layers over a light-emitting layer containing a host material selected to provide host light emission in a blue spectral region. The dopants are diffused from the dopant layer into the light-emitting layer by exposing the light-emitting layer and the dopant layers to vapor of a fluid or fluid mixture. When an ink-jet printing composition is formulated with a printing fluid having fluid vapors which promote dopant diffusion, the steps of ink-jet printing and diffusing of dopants can be combined to form a selectively doped light-emitting layer. <IMAGE> <IMAGE> <IMAGE> |
