AMOLED

Per-pixel drive, not scanned lines. A PMOLED panel lights one row at a time, so every pixel has to flash briefly and brightly as its line is scanned — the higher drive voltage that requires is what limits PMOLED to small panels. AMOLED backs every pixel with its own transistor and capacitor, so each pixel holds its state and emits continuously between refreshes at a much lower drive voltage. That is the whole basis for scaling to larger, higher-resolution, and round or non-rectangular panels without the PMOLED brightness/lifetime tradeoff.

Same self-emitting technology underneath. Like PMOLED, an AMOLED pixel is its own organic light source between two electrodes, with no backlight anywhere in the stack — so contrast, thinness and viewing angle carry over, and an off pixel is genuinely black. What changes is the backplane and the interface: AMOLED modules in this range are driven over MIPI, SPI, QSPI, or MCU parallel, depending on the controller, and pair with round as well as rectangular glass. See the PMOLED vs. AMOLED guide for the full comparison against the smaller OLED Modules line.

Choose AMOLED for a panel above roughly 3″, a round or non-rectangular shape, a higher resolution than a passive-matrix panel can drive cleanly, or a MIPI/QSPI host interface. Choose OLED Modules for a small, named-controller PMOLED part already in the catalog with a stocked or near-term lead time. Every AMOLED part today is a custom quote — bring us the size, resolution, shape and interface and a US-based engineer will scope it.
