Abstract
Organic light‐emitting diode (OLED) display panel using the charge‐pump (CP) pixel addressing scheme was fabricated, and the results show that it is applicable for information display. A CP‐OLED panel with 64 × 64 pixels consisting of thin‐film capacitors and amorphous silicon Schottky diodes was fabricated using conventional thin‐film processes. The pixel drive circuit passes electrical current into the OLED cell during most of the frame period as in the thin‐film transistor (TFT)‐based active‐matrix (AM) OLED displays. In this study, the panel was operated at a voltage level of below 4 V, and this operation voltage can be reduced by eliminating the overlap capacitance between the column bus line and the common electrode.
