AMVA (AUO Advanced MVA)Technology

Color washout is the phenomenon where R, G, and B transmittance changes due to viewing angles being out of harmony. Many specific colors being recognized by the human eye are pale as the viewing angles increase especially the skin color. This is a critical criterion to improve for LCDs. AUO AMVA (AUO Advanced MVA) technology can create more domains than conventional multi-domain vertical alignment (MVA) LCDs, and then successfully increase the viewing angle up to 178 degrees. It also improves color washout and yields better image quality at oblique angles.

The contrast ratio also dramatically dominates the image quality, particularly for dimmer images. AUO continues the development of new generation AMVA technology to provide static contrast ratio > 5000:1 with new pixel design, optimized color resist, backlight structure and optical film. This ultra high contrast technology provides higher transmittance and still retains optical properties of low color washout and wide viewing angle .

Features:

• Low color washout
• Ultra high static contrast ratio > 5000:1
• Wide viewing angle:178° / 178°
