Abstract
The inkjet printing (IJP) process based on solution‐process is a
very attractive technology because of the high material usage rate
and simple OLEDs structure. But it is not going well on the road
to mass‐product due to the various factors. The first breakthrough
is the middle‐size OLED panel manufactured which exactly
match the demand of market, process, machine and material. In
this middle‐size panel, the top emission OLED is requirement to
increase the pixel aperture ratio, lifetime and color gamut. In this
work, the bank material and process, high resolution printing
technology, in‐pixel uniformity control, and Mura Free process
were developed. Finally, an 11 inch 255 PPI top emission device
was fabricated by inkjet‐printed process.
