AMOLED means Active Matrix Organic light emitting diode


Active matrix (AM) OLED displays stack cathode, organic, and anode layers on top of another layer - or substrate - that contains circuitry. The pixels are defined by the deposition of the organic material in a continuous, discrete "dot" pattern. Each pixel is activated directly: A corresponding circuit delivers voltage to the cathode and anode materials, stimulating the middle organic layer. AM OLED pixels turn on and off more than three times faster than the speed of conventional motion picture film - making these displays ideal for fluid, full-motion video. The substrate - low-temperature polysilicon (LTPS) technology - transmits electrical current extremely efficiently, and its integrated circuitry cuts down AM OLED displays' weight and cost, too.
