Latest Patents
One of Joong-Ha Lee's latest patents is a method of driving a dual mode liquid crystal display device. This method involves applying a first horizontal electric field to the liquid crystal layer for a specified duration during a reset period of a memory mode. The process includes eliminating the first horizontal electric field and maintaining the liquid crystal layer without it for a second duration. Additionally, it applies a first vertical electric field corresponding to a static image during a writing period, followed by eliminating this field as well.
Another significant patent is for a dual mode LCD device, which consists of first and second substrates facing each other. This device features a first electrode on the inner surface of the first substrate, along with a first insulating layer, and multiple electrodes that extend in a specific direction. The liquid crystal layer interposed between the substrates includes chiral dopants, allowing for stable arrangements of liquid crystal molecules in different states for memory and dynamic modes.
