This paper described the new key technology of Dual-Cell LCD with mega contrast. V-type pixel of sub cell, which contains enhanced mosaic slit ITO, is designed for eliminating moiré, transmittance fluctuation and horizon mura. Thanks to the development of functional films, Large size Dual-cell LCD such as 110 inch was realized without any special pixel design on subcell. Although algorithm optimization was needed according to the difference of resolution between main cell and sub cell, the skill of stacking two cells directly greatly enriched the product group and lifetime of Dual-Cell LCD, as low cost as well.
