What is HCA?
| High-contrast Addressing |
|
1997 Sharp Corporation created HCA. High-contrast Addressing (abbreviated: HC-Addressing.) These displays combine high contrast to yield crisp, clear colors with a fast response speed; 150mS refresh rate, that enables full-motion video display. The most exciting news in screen technology is HPA, also known as Fast DSTN, HCA (for high-contrast addressing) and Super DSTN. It is an improved version of DSTN that offers a faster response time, higher contrast ratio and wider viewing angle. This is an ideal solution for many mobile PC users and is poised to replace DSTN in mid-range and value mobile PCs. It provides better viewing than a DSTN display at a better price than TFT. |
