Final answer:
Vertical Alignment (VA) display technology is primarily characterized by its ability to achieve deep black levels, owing to its efficient backlight blocking in pixels when displaying black.
Step-by-step explanation:
Vertical Alignment (VA) display technology can be characterized mainly by its deep black levels. In flat screen LCD televisions and monitors, pixels, composed of red, green, and blue cells, control the passage of light through filters. VA panels are known for their ability to block this backlight more effectively when a pixel is supposed to display black, which enhances the perception of deep blacks on the screen. Unlike other types of LCD technology such as IPS (In-Plane Switching) that are known for their wide viewing angles and fast response times, VA panels typically have more limited viewing angles and can have slower response times, although many modern VA panels have improved in these respects. However, they still generally do not match the refresh rates typically found in TN (Twisted Nematic) panels.
