High-Performance Addressing

High-Performance Addressing (HPA) was developed by Hitachi and is an LCD Passive-matrix display technology commonly found on low-end portable computers. HPAs have higher response rates and contrast, and are capable of displaying up to 16-million colors; however, they lack the crisp display that is found with an Active-matrix display.[1] HPA uses a technique called multiline addressing in which the incoming video signal is analyzed and the image is refreshed with a frequency as high as possible.[2]
