Final answer:
VA display technology is known for its wide viewing angles and deep blacks. VA panels use pixels with RGB filters controlled by liquid crystals to form images. High refresh rates and low power consumption are not characteristic features of VA displays.
Step-by-step explanation:
Vertical Alignment (VA) display technology is a type of liquid crystal display (LCD) technology that is often used in flat-panel displays such as televisions, monitors, and laptops. VA displays are known for their wide viewing angles and the ability to display deep blacks, which contribute to a high contrast ratio. They use millions of tiny units called pixels, each pixel containing cells with red, green, or blue filters. When voltage is applied to a liquid crystal within the pixel, it controls the passage of light through these filters, which ultimately contributes to the image that appears on the screen. While VA panels can offer certain advantages, they may not necessarily excel in terms of high refresh rates compared to other technologies, and their power consumption can vary based on the specific implementation and backlighting technology used.
