Through QD-polarizer[1], the viewing-angle and color-gamut of VA-LCD is significantly improved as well as IPS-LCD and OLED. But dark-leakage also excists just like normal VA-LCDs. The influence of dark-leakage is simulated and verfied by test. A significantly decrease (-80%) in dark luminance by optimizing the compensation value is discovered.
