We propose an advanced patterned vertical alignment (PVA) mode with a fast response time through double ultraviolet (UV) exposure to UV curable reactive mesogen (RM) mixed in alignment layer. The double step UV exposures using a photomask divide an active pixel region into two regions with a modified pretilt region and a high elastics deformation energy one.
متن کاملAdvanced Patterned Vertical Aligned Nematic Mode to Elevate Transmittance
This paper presents an advanced patterned vertical aligned nematic liquid crystal (APVA) mode as a way of improving the transmittance of the conventional patterned, vertically-aligned nematic liquid crystal (PVA) mode. The APVA was characterized by multi-electrodes, which play an important role in generating a horizontal electric field that prevents LC disclination in the vicinity of the middle...
متن کاملFast vertical alignment mode with continuous multi-domains for a liquid crystal display.
We proposed a fast liquid crystal display (LCD) in a vertical alignment (VA) mode with continuous multi-domains for wide-viewing characteristics. The fast VA LCD was fabricated by the mixed vertical alignment layer with UV curable reactive mesogen (RM) polymer memorizing the switching directions of the LC molecules. The wide-viewing and fast response characteristics were obtained by axially sym...
متن کاملNematic cells with defect-patterned alignment layers.
Using Monte Carlo simulations of the Lebwohl-Lasher model we study the director ordering in a nematic cell where the top and bottom surfaces are patterned with a lattice of +/-1 point topological defects of lattice spacing a . As expected on general physical grounds we find that the nematic order depends on the ratio of the height of the cell H to a . For thick cells (Ha > or = 0.9) we find tha...
