Abstract
In this research, we describe a facile design of white organic light
emitting diode (WOLED) displays applicable to 8K4K resolution of
large‐area displays. We demonstrated a 13.3‐inch diagonal size
(166 pixel‐per‐inch) of WOLED display, including a self‐aligned
oxide thin‐film transistors, simple pixel driving circuit, external
compensation method, fast driving integrated gate driver circuit.
The narrow bezel of 3.9 mm is realized when multi‐output gate
driver circuit is applied. The required function for external
compensation method is realized by the integrated gate driver
circuit. The external compensation improved global luminance
uniformity, especially at the low gray level.
