This paper presents an alternative approach for achieving higher optical efficiency in conventional parallax barrier 3D mobile displays. The method entails modifying and enhancing the protrusion structure of conventional multi-domain vertical alignment (MVA) pixel arrays plus the storage capacitors (Cst) of the pixel circuitry which increase effective pixel transmission area by a factor of 1.07. Hiding the modified storage capacitor under the parallax barrier strip increases the barrier gap or slit size by a factor of 1.52. The result is a structure that enhances mobile displays' optical efficiency by a compounded factor slightly over 60% without compromising power consumption.
