High ContrastAddressing (HCA) is a driver technology for LCD displays
. The HCA technology enables a higher refresh rate and a simultaneous control of several lines. Therefore, HCA technology is characterized by shorter response times of
LCD cells, improved contrast ratio, which is over 50:1. Thelatter is less than 100 ms and is due to the multi-line addressing. The
brightness and luminance is higher than that of LCD displays and is over 200 cd/sqm. LCA technology is used in laptops, handhelds, digital cameras and mobile phones.
