According to foreign media reports, the iPad 2 generation is expected to use AMOLED (active-matrix organic LED, active matrix organic light emitting LED) screens, but it will eventually be abandoned due to capacity problems. Reported that although Taiwanese manufacturers are trying to keep up with the pace of South Korean manufacturers, they still cannot meet Apple's requirements. The main reason why Apple gave up using the AMOLED screen in iPad 2 is that the production capacity is difficult to meet. South Korea's Samsung is currently the main supplier of AMOLED screen panels, offering 2-inch to 4.2-inch models, but Samsung's production capacity can not even meet the needs of their own Galaxy S, Google Nexus S and Nokia and other vendors.
In addition, the current AMOLED technology is not suitable for mass production of 7-inch to 11-inch panels, and even if mass production, the cost is higher than the current TFT LCD panel.
Another source said that Apple has conducted an AMOLED screen test on the iPhone, but decided to give up because it is not suitable for displaying text messages.
