AMOLED is Active Matrix OLED. An Active Matrix OLED uses a TFT (Thin Film Transistor) transistor-per-pixel architecture. Using a transistor-per-pixel allows higher resolution displays to be made and avoids the problems associated with high duty cycle passive displays.

Detailed Definition

In an AMOLED, once a pixel is turned on, it can stay on for the entire frame time. Compare this to a 1/64 duty cycle PMOLED (Passive Matrix OLED) where a pixel can be on at most 1/64 of the frame time.

Active Matrix OLEDs have fantastic resolution, great brightness, and super viewing angles. Active Matrix OLEDs are typically full color using red, green, and blue sub-pixels.

Additionally, since there is no backlight required, an OLED can be made extremely thin.

AMOLED Display Manufacturing

Manufacturing of AMOLED displays is much more difficult than PMOLED displays. Currently, this has AMOLED displays priced much higher than a similar backlit color TFT LCD display.

As the technology matures, high volume production will likely drive the cost of AMOLEDs displays lower, perhaps approaching TFT LCD displays.
