摘要：

A charge-pump (CP) pixel addressing method for an organic light-emitting diode (OLED) display panel is shown to be feasible by implementing pixel arrays of both OLEDs and semiconductor light-emitting diodes (LEDs). It is also shown that the light output from the CP-OLED can be made to last for the entire panel scanning period and that the crosstalk between pixels can be minimized by a proper choice of drive signal waveforms. A SPICE circuit model is developed, and a pn-junction model is found to be effective in the numerical simulation of CP-OLED display panels. It is also found that a high contrast ratio and a high luminance level can be achieved using the new pixel addressing method.
