Sony develops “Hybrid FPA”, a novel liquid crystal alignment technique that achieves faster response time for liquid crystal displays
Sony has developed “Hybrid FPA (field-induced photo-reactive alignment)”, a new liquid crystal alignment technique which enables a significantly faster response time for liquid crystal displays. Fast responses of less than 3ms have been achieved in test cells through this technology. Aside from contributing to ‘picture quality enhancement in 3D and high frame rate video’, this technology will improve ‘product stability’ during the display panel manufacturing process as well as after long-term use. Additionally, this technology will achieve production efficiencies by reducing the manufacturing process and time.
The new “Hybrid FPA” technology is the result of further development of the aforementioned “FPA” technology with its superior features. “Hybrid FPA” technology has achieved an even faster liquid crystal response time by maintained the pre-tilt on just one side of the substrate alignment layer (see illustration). Furthermore, this new technology has succeeded in facilitating drastic improvements in liquid crystal response time, especially faster movement of liquid crystal molecule when decreasing the voltage which was previously difficult to achieve, as well as higher contrast.
