Abstract
In this study, we proposed a tandem structured 2-color micro-polymer light-emitting diodes (μ-PLEDs) for super high-resolution organic light-emitting diodes (OLEDs) micro displays. The proposed 2-color polymer light-emitting diodes consisted of red and green colored polymers patterned to 20 μm. For the tandem structure, we adopted the recently developed sol-gel process to obtain the orthogonality of organic semiconductor against the solvents and chemicals so that we could apply the standard photo-lithography and dry-etch process to achieve micron-size patterns of light-emitting polymers. Experimental results showed that we could achieve the maximum luminance of the tandem structured 2-color PLEDs up to 140 cd/m2 at 8V
