Abstract

This investigation reports the optical simulation of axially symmetric vertically aligned liquid crystal displays (ASVA LCDs). The circularly symmetric iso-light leakage and iso-transmittance contours of one subpixel result in the circularly symmetric iso-contrast contours. The contrast ratio of the area close to x- and y-axes at a polar angle of around 30° exceeds 10. The LCs near some azimuthal angles are not perfectly aligned in circularly symmetric manner because of the square subpixel. Such a reason causes major reduction of the light utilization efficiency. Additionally, the circularly symmetric iso-contrast has potential for fabricating private mobile products.
