Latest Patents
Vithana's latest patents include a groundbreaking design for a vertically aligned nematic mode liquid crystal display. This innovative reflective liquid crystal on silicon (LCOS) display features a transparent substrate, a reflective substrate, and liquid crystal fluid positioned between the two substrates. The design incorporates a matrix of pixels arranged in rows and columns, where the intersection of each row and column defines the position of a pixel. The LCOS display is engineered to achieve tilt angles that effectively overcome disclinations caused by fringe fields, while also ensuring high contrast. The orientation of the liquid crystal molecules is carefully controlled to minimize light leakage, resulting in an effective birefringence that is substantially zero. This design allows for a twist of the liquid crystal molecules to vary from 0 degrees to 90 degrees when in the 'OFF' state, enhancing the display's overall performance.
